    News

    1. One of China’s top government departments published on Sunday a list of eight schools, which charged students a total of 22.7 million Yuan in the extra tuition fees last year.

    This is the first time step in a campaign by China’s State Development and Reform Commission (SDRC) to crack down on this banned practice.

    According to the commission, in the first seven months of 2005, 23.8 percent of all the pricing complaints it received were about schools’ arbitrary fee collection.

    One typical case involved a student majoring in art and design at China Xi’an Academy of Fine Arts. The school’s standard fees were 9,000 Yuan last year, but the student paid 15,000 Yuan.

    According to the Ministry of Education, universities can only charge tuition and accommodation fees.

    Illegal extras:

    Charging other fees, such as for transferring majors, using accommodations during vacations, admission registration and compulsory laundry fees, is all illegal.

    One of the reasons that schools charge extra fees, according to some experts, is that some schools are underfounded.

    Compared with many developed countries and even some developing countries, China’s expenditure on education is low. The world’s educational spending as a percentage of GDP is above 5 percent on average. China spends about 3.5 per cent in 2003.

    The blacklist has triggered much online discussion. The BBS board has become a place for unhappy students to expose schools’ unreasonable fees.

    The commission is encouraging people to report illegal fees through hotline “12358”.

     

    2. The Chinese government issued strict guidelines for the nation’s entertainment venues last week. One of the rules says that businesses like disco and karaoke clubs will be closed between 2:00 am and 8:00 am. This news has spurred different opinions. Officials say that it’s a great harm to health if people stay up all night and will affect their working spirit. But many respondents say since many consumers are adults, it should be their own choice whether to stay late or not. And they also doubt whether many entertainment venues will follow the rules.

     

    3. Pakistan’s president Pervez Musharraf is now in China on a five-day state visit.

    During the visit, Musharraf is expected to strengthen the country’s close relationship with China.

    The president voiced his regret on Monday over the murder of three Chinese engineers in his country. He said Pakistan was committed to strong relations with China. The two countries went on to sign several co-operative pacts.

    The incident was not the first tough spot Musharraf has handled.

    He has survived numerous assassination attempts. It is reported that he carries a gun all the time.

    The key to understanding Musharraf is his background as a military man. He still bids farewell to civilians, and even foreign journalists, with a crisp salute.

    He joined the military at the age of 18. He took over the government through a bloodless military coup in 1999. He was elected as president in a referendum in 2002. He didn’t take off the uniform until the end of 2004.

    Although he announced he would leave the military staying president of the country only, he still holds considerable influence over the army.

    On the other hand, Musharraf is a natural sportsman, who loves to spend most of his leisure time playing squash, badminton or golf.

     

    4. Health officers in Hong Kong and Singapore warned this week the solution of contact lens may not be safe anymore.

     Think twice before using Bausch and Lomb’s ReNu multi-purpose contact lens solution.

    Health officers in Hong Kong and Singapore warned this week the solution may be unsafe.

    Over the past two months, the number of fungal eye infections related to contact lens use has jumped in both areas.

    In Singapore alone, seven cases were reported last month and three more in the past week. Most of those affected sued the ReNu product.

    Current batches of ReNu in Singapore are being tested, and so far have passed. Hong Kong is carrying out similar tests.

    Bausch and Lomb’s Bain Levy said ReNu was subject to stringent cheeks in the US, and that the solution worked better against the particular fungus than other brands.

    Bausch and Lomb China said that ReNu sold in Hong Kong and Singapore is imported from the US.

    However, 98 per cent of the ReNu sold on the mainland is made in China. The company has not planned to suspend sales of the product here.

    Medial experts suggest the eye infection could also be caused by poor hygiene on the part of contact lens users. Some also say the tropical climate might also be the cause of the infection.

     

    5. A mother from the UK lost her High Court battle last month for a parent’s right to be informed about girls under 16 seeking advice on abortion.

    The case has raised the issue of what parents are entitled to be told about their daughter’s sex lives.

    The judge said that informing parents without their children’s consent “may lead (a girl) to make a decision that she later regrets or seek the assistance of an unofficial abortionist”.

    But a Times newspaper survey of readers’ opinions last month found little agreement on the best approach.

    Ian Allen from the UK said British society was “deeply confused about our attitude to the sexual behaviors of teenagers under 16”.

    “Parents don’t have to be consulted by doctors when they give advice on contraception or abortion to girls aged 14 or 15. Is there any lower age limit where parents will be consulted?” he asked.

    Briton Katie Majersk argued differently: “if to have an abortion under 16 requires parental consent, then that implies that consent could be denied. This would force a child to be pregnant, give birth and become a mother.

    An anonymous teenage girl reader said: “I personally would inform my parents if I became pregnant and was considering an abortion. I hope I am in the majority there...”

    However, “the decision to tell parents should remain the girl’s choice,” she continued. “If a girl does not want to tell her parents there may be a good reason for this.”

    “It is a sad fact, especially in American culture that a girl under 16 having any kind of sexual experience is frowned upon. It is this prevalent social attitude that has driven every back-alley abortion ever performed.

    “This attitude has never gone away. Until this attitude is completely eradicated, the need to obtain sexually related advice [from parents] will remain necessary.”

     

    Culture

    Evaluation on Overseas study

    New friends. Fresh lifestyle. Better career opportunities… Those are the attractions of overseas study for young people. Like Zhangxiao.

    Zhangxiao is only a sophomore student from Beijing Normal University, but he’s already considering studying abroad. “Start early, finish strong.” He says.

    He said that last weekend’s international education exposition was a starting point.  More than 300 universities from 27 countries and regions were represented at the expo. Zhang explored and shared what he learned with us.

    1.The US

    The US has always been on the top destination list for Chinese students, with its high education standards and abundant scholarships.

    Good news: It’s easier to get a US student visa nowadays. Last year, the refusal rate was only 20 to 30 per cent, much lower than a couple of years before, according to US embassy.

    Concerns: They’re a lot to prepare. The TOEFL, GRE…its longer time to apply to US universities than schools in the UK or Australia.

    2.The UK

    Easier access to visas and international environment are the UK’s great attractions for Chinese students.

    Good news: There are many new scholarships this year, both from the government and universities, such as the Scotland International Scholarship.

    Concerns: Money. Money. Money. It’s expensive to study in the UK, with an average cost of 200,000 to 300,000 Yuan a year.

    3. Canada

    Canada’s multicultural environment is good for students’ study and careers.

    Good news: Students are allowed to take off-campus part-time jobs during their studies from last year work permits after graduation.

    Concerns: Only a limited number of scholarships are available. They rarely cover the full cost of a study program.

    4. Australia

    Good climate, high quality education, favorable immigration policy: these make Australia one of the most popular choices among Chinese students.

    Good news: A new E-visa policy ensures a quicker application process (4weeks compared with 12 weeks before).
    Concerns: Tuition fees have risen in past year. The total cost is about 200,000 Yuan to attend a university located in big cities like Sydney or Melbourne.

    5. Singapore

    You’ll feel at home if you study in Singapore. The bilingual (Chinese and English) environment will ease you from culture shock.

    Good news: Government grant program helps to pay your tuition fees and allows you to work for a Singapean company after graduation. And a newly-established help centre for international students provides more aids.

    Concerns: Singapore is too close to home. Maybe I’d prefer a more different life.

    6. Italy

    Italy is getting a lot of attention this year in China, with the China-Italy year. Its art, culture and fashion appeal too many.

    Good news: China and Italy will recognize each other’s educational certificates soon. Its government-funded universities are tuition-free to international students.

    Concerns: The language is a problem. Most classes are taught in Italy.

     

    Entertainment

    English brands and their Songs:

    (Back street boy and West life)

    Nearly 5 years after their last studio album, the Backstreet Boys mark a resolute return with their 5th disc June 14 on Jive Records. The 12-song "Never Gone" reflects the adult ideals of a quintet that broke music and concert sales records the world over, moving more than 73 million albums (30 million in America) since their introduction in 1997.

    Certainly, pop culture remains on a first-name basis with the five singers that comprise BSB: Nick Carter, Howie Dorough, Brian Littrell, AJ McLean and Kevin Richardson. When they scored in the U.S. with the debut platinum single "Quit Playing Games (With My Heart)"-followed by such radio staples as "Everybody (Backstreet's Back)," "All I Have To Give" and the No. 1 (in 18 nations) "I Want It That Way"- the Backstreet Boys grew to personify an unprecedented and celebrated youth-driven era in popular music.

    As teen idols, they sold more than 13 million copies each of their first two U.S. albums, "Backstreet Boys" (1997) and the No. 1 (in 25 nations) "Millennium" (1999). "Black and Blue" followed (2000), moving 8 million copies, and then "Hits: Chapter One" (2001), another platinum triumph. Along the way, the group logged12 top 40 hits, 8 of those reaching the top 10.

    Today, nearly a decade since their initial success-and following a healthy 3-year breather-each group member admits that they needed time to catch up, grow up and gain some perspective on the whirlwind of fame.

    "We had been touring pretty much non-stop for 7 or 8 years and we were almost living in a bubble; we had lost perspective on a lot of things," Kevin says. "You need to take care of yourself and rest and be able to reflect. This time off gave us a chance to recharge our batteries and step away and see what has happened in our lives, what we have accomplished and to be thankful for the opportunities that we have had and thankful for each other."

    Brian became the first Backstreet Father during the break, Kevin took on Broadway and London West End with a starring role in "Chicago," Nick put out a solo project and Howie continued his efforts with the Dorough Lupus Foundation after the loss of his oldest sister Caroline in 1998. AJ McLean worked through personal demons with a well-publicized stint in rehab.

    "I've been sober for 2 ?years," AJ says. "I appreciate my family more, these guys more and myself more. Life is great. It's worth living again."

    "Never Gone," which BSB spent more than a year recording, accomplishes the formidable task of moving beyond pop idol notoriety to reflect what is happening in the group's lives and in the world. The project features intensely personal, upfront vocals, coupled with production that spares drum loops and synthesizers for a mature, live, more rootsy vibe. Don't worry-the pandemic hooks and velvet harmonies are still there, behind lyrics that tell universal stories of hope, loss, redemption and love.

    First single "Incomplete," released in April, proves Backstreet Boys' enduring relevance; in its first week out, the ballad was most-added at radio. By the end of May, the song was climbing the top 10 on Billboard's mainstream top 40 chart as well as the top 5 of Top Digital Downloads. The accompanying video clip reached No. 1 on AOL and garnered rotation on MTV, VH1 and MuchMusic.

    Title track, "Never Gone," is among the most moving songs on the album. Written by BSB's Kevin Richardson with Gary Baker and Steve Diamond, the harmony-drenched ballad pays tribute to the death of Kevin's father. It is produced by Mark Taylor.

    "That song has really been important to each one of us," AJ says. "In addition to the loss of Kevin father, I lost both of my grandparents, Nick his grandmother and Howie his sister. We've all experienced great losses, so this song really touches us personally."

    Additional name-brand collaborators that assisted in launching the Backstreet Boys' Chapter 2 include Billy Mann on "Poster Girl", and Switchfoot's John Fields on "Lose It All". Five for Fighting's John Ondrasik contributes "Weird World," a song that examines in life in post 9/11 society.

    The guys also worked with John Shanks, the 2005 Grammy Award Producer of the Year ("Safest Place To Hide"); and the venerable Max Martin, who helped catapult to fame Ace of Base, Britney Spears-and BSB, with "Quit Playing Games (With My Heart)," "As Long As You Love Me" and "Everybody (Backstreet's Back)."

    Martin collaborated on 4 of the 12 songs on "Never Gone," including "Climbing the Walls," a tour de force of conflicting emotion, coupled with a melody so immediately gratifying, you'll be singing along by the second chorus; and the melancholy love song "I Still," which features skyscraping vocals and a magical mesh of harmonies that should be a patented trademark for the Backstreet Boys. Martin also worked with BSB on "Just Want You To Know" and "Siberia."

    Being in the studio together for the first time in years, it took the group some time to integrate their different musical influences. But according to AJ, "Once we got with Max, everything shifted and we started going more toward contemporary, alternative pop with a little R&B. We found exactly what we are supposed to be doing for this album. It's more organic, with more live instruments, and a nice departure for us. If we kept on doing what we used to do-with the way music sounds today-people wouldn't care anymore. We had to step ahead of ourselves."

    Brian adds, "It was essential for us to grow. If we're not getting better and challenging ourselves, what are we here for?"

    Certainly, the average life span of most acts in popular culture is far less than a decade, but the Backstreet Boys are proving that growing with your audience-while staying true to a track record of timeless melodies-cultivates the rare gift of endurance. Indeed, Backstreet's back... again.

    "We're excited and we hope our fans are, too," Kevin says. "We're looking forward to a happy, prosperous 2005."

    1. Debutante wins China's first gold

    At the end of the fifth day of the 2006 Turin Winter Olympic Games, China, a summer sports powerhouse, finally ended its gold medal drought.

         Calm and under no pressure before the Olympics, the 20-year-old said she felt all the tension in the run-up to her gold.

         "I felt very tense from the very beginning and even after the race, I could net calm down.

         "This is my first Olympics and I have to admit the Olympics is really a special competition.

         "I never thought about the specialty of the Olympics but when I stood on the track, I felt it was totally different. Even now I ask myself, Am I an Olympic champion?"

         It was the third winter Olympics gold medal for China after Yang Yang (A) clinched two at the 2002 Salt Lake City Games.

         Following a perfect World Cup season in the women's 500m, where she finished first in all four competitions, Wang was China's biggest gold medal hopeful.

         "I feel no pressure at all but the responsibility, “Wang said before leaving for the Olympics. " The whole country is supporting me and I should be responsible for making some contribution for my motherland."

         At the Turin Games, the burden of winning the first gold for the country fell on Wang Meng.

         On Tuesday, Wang Manli a favorite in the women's speed skating 500m crumbled under pressure, winning only the silver.

         A day earlier, Zhang Dan crashed spectacularly in the free skating of the figure skating pair’s competition, effectively ending hopes of winning gold with her partner, Zhang Hao, giving China yet another silver.

        "After the 500m heats on Monday, I began to feel nervous...But I told myself to do the best I could and in the end I did it.: Wang said.

        She led all the way from the heats to the final.

        The joy of victory made the young skater so exited that she jumped onto the podium even before her name was announced at the awards ceremony.

       Wang's victory continued China's dominance in this event and earned her high praise from team mate Yang, who did not participate in the 500m competition this time. "Wang did very well today since she shouldered heavy pressure."

     

    2. Ancient city plans massive relocation

    XI'AN: Chinese cities are often accused of ignoring their cultural and architectural heritage in the blind pursuit of modernization-but Xi'an is taking a radical step to protect its historic relics.

    The capital of Northwest China's Shanxi Province.-plan to relocate its administrative centre from the downtown area to the northern suburbs.

      Xi'an, with a 3,000-year history of urban construction, was the capital of 13 dynasties. The downtown area, inside the 13.7-kilometre-perimetre city will build some 600 years ago, used to house the imperial palace and the commercial centre in the Tang Dynasty (AD 618-907).

    “The relocation will start later this year, together with a project to rebuild ancient palace and commercial areas,” Major Sun Qingyun said yesterday at the ongoing session of the local legislature.

    The restoration plan will better preserve ancient buildings, ruins and relics-considered non-renewable cultural heritage- and improve urban planning, Sun said.

    The relocation, costing about 50billion yuan (US$6.17 billion), will be completed in 30 years.

    Currently almost all official organs including the municipal government, the municipal Party committee and the local people’s congress are located downtown, which also has commercial centre and residential buildings, said Guo Zhifeng of the municipal urban planning bureau.

    “The present layout of the downtown area is suitable neither for the development of the city nor the preservation of ancient relics. Also, there are traffic jams every inside the city walls,” the urban planning official told China Daily.

    According to Zhang Baotong, an expert on socio-economic development who took part in Xi’an’s revival plan, cars will be banned in the downtown area inside the city walls, and the population will decrease to less than 250,000 from 450,000.

    The local government will build a satellite town in the eastern suburbs for residents to be located from the downtown area, said Wang Jun, director of the new town’s construction committee.

    “Wu Deyuan, a downtown resident, told China Daily after hearing the relocation plan: “I have been living inside the city walls for 71 years and I’m really reluctant to say goodbye to the place. But I understand it is necessary for Xi’an’s development.

     

    World News:

    1. American Idol’s steals gold in ratings

    US television viewer proved they prefer amateur singers to champion skiers and figure skates as the hit talent contest “American Idol” stomped NBC’s coverage of the Winter Olympics in the rating.

    “American Idol” on the Fox network averaged 26.3million viewers on Tuesday night, compared with just 16million who tuned in during the same hour for NBC’s taped-developed broadcast of the Winter Games, according to early figures from Nielsen Media Research on Wednesday.

    Among viewers aged 18 to 49, the audience group most prized by advertisers, “American Idol” had more than double NBC’s ratings in head-to-head competition against the Olympics.

    Fox, a unit of News Corp. Ltd., even gave NBC a run for its money in the next hour of prime time, as the medical drama “House” ran nearly even with the Winter Games in total viwers-20 million for “House” vs. 20.8 million for the Olympics-and trounced NBC in ratings among 18 to 49-year-olds.

    For the night as a whole, Fox surpassed NBC’s prime-time Olympics coverage, including America’s first gold-medal victory in men’s alpine skiing in decade-23.1 million viewers to 18.5million overall- and soundly beat NBC in the 18-49 category.

    The pop star wannabes of “American Idol” likewise outshone the likes of Madonna, U2 and Cold play in last Tuesday’s match up against the Grammy Awards on CBS, averaging 28 million viewers compared with 15 million for the Grammys.

    Predictably, this year’s Winter Olympics in Turin, Italy, have so far failed to attract the viewers of the 2002 gems in Salt Lake City, Utah, which enjoyed a stateside advantage allowing live telecasts of many of the marquee events.

    The Turin game’s biggest stars when skating champion Michelle Kwan withdrew from competition on Sunday due to a groin injury, ending her unsuccessful quest for Olympic gold.

    Despite being bested by fox and “American Idol,” the Turin games gave NBC it’s most watched on Wednesday night in total viewers since the Summer Games in Athens in 2004.

    Last Tuesday’ broadcast of the talent show drew 30 million viewers, nearly 4 million more than during  Olympics week.

     

    2. Real world’s richest club

    Real Madrid has over taken Manchester United to become the richest club in world soccer, ending the English club’s eight-year reign at the top.

    The Football Money League report published by consultants Deloitte yesterday also shows that combined revenues from the game’s top 20 earning teams broke through the 3 billion euros barrier for the first time.

    Much of Real’s success was down to the Spanish club capitalizing on the global appeal of player such as David Beckham, Zinedine Zidane, and Ronaldo, the report said.

    The report points to a possible shift away from the dominance of English and Italian clubs, with a rise in the status of French and German teams predicted.

    “During the next few seasons, we expect to see a stronger financial showing from German and French clubs. In each country there are new broadcast deals that will significantly enhance clubs’ revenue,” it say.

    Stadia devlopent of miore than a billion euros ahead of the 2006 world Cup in Germany will also provide seect Bundesliga club’s with the opportunity to increase both matchday revenue, as many UK clubs have over the past decade.”

    Real mdrid, though, remain the success sstory with a business model other clubs should be looking to emulate.

    “Real have ‘broke the mould’ in terms of revenue growth for football… it is the clubs’s ability to grow commercial revenues that has guided it to the top of the Money Leage,” said Doloitte.

    Dan jones, from Deloitte’s Sports business group, said: “ Real Madrid’s top spot…respresents a remarkable transformation in the club’s revenue generating capacity.

    Jones said the total revenue of the top 20 clubs –all of them European- broke the 3 billion euro barrier for the first time in 2005-05, demonstrating it is still a growth sport at the highest level.

    English side occupy 8 of the top 20 positions, Italian sides account for 5, followed by Spain (3), Germany(2), and one each from France and Scotland. Fourteen of the clubs reached the UEFA Champions League group stages.

    Deloitte predicted that German and French clubs would make a stronger showing over him next few seasons through new broadcasting deals. Germany was also likely to benefit from hosting the World Cup later this year.

     

    Culture Talking:

    In today’s culture talking we will have a conversation about the two words-Come and go.

    A: Wange, you suggested we talk about COME and GO in this dialogue, which made me immediately recall a song I remember, “Love, love you Darling’ COME and GO with me…” It comes from a song titled COME GO with me sung in 1957 by a group called Dell-Vilings.

    B: I read about a drama titled COME and GO written by Beckett in 1965. The whole piece has only 121 words. Three women meet in a softly lit pace. Seated on a bench facing the audience, they reminisce about old school days. Each woman leaves the stage briefly, and during her absence an appalling secret is whispered about her, which the audience doesn’t hear. At the end the three hold hands saying, “I can feel the rings.”

    A: I think this shows that people and events COME and GO, and we, as human beings, have the capacity to value what is most important, making connections with each other despite all the Comings and Goings.

    B: Beckett was very philosophical. So many things COME and GO, but only a few GO down in history.

    A: I agree. IN the case of the expressions COME on; let’s go, which are commonly said together, the meaning suggests we will be moving in the same direction at the same time and right now. I guess that could be confusing as by definition come and go are considered opposites.

    B: Most of the time, it seems to me, come and go are used in the sense of come on here, and go over there and are frequently used in commands or as imperatives like your examples. I guess that’s why they come up in sports songs. Do you know that popular song for soccer games, “GO GO GO, aller, aller, aller…”?

    A: well, that go means get busy, make some points, and win. No, I have heard it. Maybe that’s because soccer is only beginning to come into popularity in the US. The “Aller, aller, aller” portion is very European-French to be exact. Can you imagine a group of American sports enthusiasts singing “Aller, aller, aller”? I would go just to hear that.

    B: This was the song sung in the World Cup Soccer game held in France in 1998 if I remember correctly. That’s how “Aller, aller, aller” comes in. Not many Americans go for soccer. However, they would certainly shout go for their favorite football team as is demonstrated by the Ohio State University Buckeye song Let’s Bucks! “Go Bucks” means “go all out”, I guess.

    A: Well, to go all in a gem means get busy, make some points, and win. People always want their favorite teams to go all out. Shouting go team is common in the US, but “aller” never. I like the idea of the European flavor with go and “aller” combined. By the way, I haven’t heard from you in a while. What’s been going on in your life?

    B: Well, we just finished celebrating the most important Chinese festival- the Spring Festival.  After the Chinese New Year, comes the Lantern Festival. Now that the Spring Festival is over, people have to go back to work. So time for me to come back to our conversation.

    A: How did the festival go? Did everything come off as planned? Ah, there’s another use of come that doesn’t mean movement. Come off is idiomatic for happen. Well, did everything happen as planned?

    B: As far as Spring Festival go, this one came off pretty well. My eldest sister came down to Shenzhen to spend the New year with us. We saw some kids being strapped into harnesses and then bouncing up and down in the air. Qiqi, who is always on the go and very curious about new things, decided to go for the game. I went for the par

    nachutes. At first, I was rather scared, but my wife encouraged me, so I gathered up my courage and decided to have a go at it. It was a thrilling experience, and I landed safe and sound.

    A: How high in the air did you go? Did you come down from an airplane or from an amusement park tower? Wow!! I am impressed. How did if feel to come down as if you were floating? At a brief moment in my life I wanted to try hang gliding just to feel a sense of floating on air, but that never came to be. I couldn’t go through with it. Too chicken, I guess.

    B: I didn’t go up very high. The parachute was pulled by a boat that was circling in the water. I went up as the boat circled, and I instantly panicked as I was lifted into the air. But I soon calmed down. “Keep cool,” I kept saying to myself. I was in the air for about twenty minutes. It wasn’t as scary as I had thought after all.

    A: I’m sorry. That sounds too scary for me, but I guess it must be fairly safe or no one would go on the ride. It sounds like the holiday did come off well.

    B: Yes, very well indeed. If the parachutes sound too scary for you, the dice game Easy come and easy go might be easier and safer.

    B: looks like we should just keep the conversation going on and on. But all things must come to an end. So, that’s all we talking about today, and say goodbye to our audience. See you next time.

    A: see you.

    The Lion King is an animation which depicts adventures and legends that happened in the animal world. It is the Disney film makers who with their intelligence and creativity, worked wonder within four years of hard work. Lion King was presented to the audience in June, 1994, touching a lot of people with the vivid cartoon images and magnificent view. It is not only a great success in box office, but also redefined animations. It won the Academy Award in 1995. Here is the main plot of the movie.

    The first half of the film focuses on Simba's youth, with a couple of scary scenes — the first in an elephant graveyard and the second a wildebeest stampede — both engineered by his evil Uncle Scar (Jeremy Irons).

          After the death of Simba's father, Mufasa, Scar convinces Simba that he's to blame. So, Simba banishes himself from the land of his forefathers, while Scar and the hyenas take over.

          Meanwhile, Simba makes friends with Pumbaa and Timon, as he grows to adulthood. Pumbaa and Timon introduce Simba to the joys of leisure and a steady diet of bugs, until one day the lioness Nala shows up. She tells Simba of Scar's treachery and asks him to return and take his rightful place on the throne.

         Simba then gets a piece of advice from the ghost of his father, ultimately returning home to set his house in order and face the truth about his past.

    Next we will listen to a conversation between Simba and his father about the circle of life.

    2. Harry Potter and the Goblet of Fire

    Between sci-fi and fantasy, fantasy won out this year. With its adjusted score of 81.77 and an 89% on the Tomatometer, "Harry Potter and the Goblet of Fire" takes the Golden Tomato Award for the best-reviewed sci-fi/fantasy movie for 2005, beating out "Serenity" and the final installment of "Star Wars." In his fourth year at Hogwarts, our young wizard-in-training Harry Potter is set to compete in the granddaddy of all tournaments -- the Triwizard Cup, where competing schools gather in a not-so-friendly competition for bragging rights. But danger lurks behind the scenes. Eleanor Ringel Gillespie of the Atlanta Journal-Constitution called "Goblet" "indisputably the best movie in the franchise thus far," while Carrie Rickey of the Philadelphia Inquirer proclaimed it to be "the most fun and the most fraught with conflict." Where will the next one in the series land in 2007? Stay tuned.

     

  •   新浪科技讯 从没有仰望过星空的种族是不会产生宇航的冲动的,从这一点上讲人类是幸运的:由于地球和太阳系处于银河的边缘,四周恒星的密度远比银河中心地带低,因此无论何时地球总有一半的表面处于黑暗之中,这使得人类自诞生之日起就能领略到神秘、浩瀚、浪漫的宇宙空间的无穷魅力,从而产生跃入虚空的梦想,这种萦绕千年的梦想正是20世纪人类航天冒险的强劲动力。

      载人航天是航天工程中最尖端、最复杂的部分,对一个国家的科技、经济、军事和政治等方面都具有非同寻常的意义,众多世界强国包括部分发展中国家都对载人航天活动抱有浓厚兴趣。中国成功地加入世界载人航天俱乐部是一个标志性事件,它集中反应了中国近年来力量与信心的增长,这种增长将对世界战略格局产生深远影响。

      漫漫天途

      最早的载人航天活动开始于东西方阵营的激烈对抗与竞争时期,在漫长的冷战岁月里,美苏两国的载人航天计划带有浓厚的政治宣传和意识形态色彩,双方都不遗余力地想在太空竞赛中获得领先地位,以证明自己在社会制度和国家力量方面的优越性,即使这种竞争耗尽了国家的血脉也在所不惜。这是一场漫长的、代价巨大的赌博。

      1957年10月4日,苏联科学家们将刚刚试射成功的P-7洲际弹道导弹改装为“卫星”号运载火箭,用它发射了世界上第一颗人造地球卫星,这一成就极大地震撼了西方世界,似乎一夜之间苏联的科技能力已经领先于美国。1961年4月12日,苏联使用“东方”号宇宙飞船和“东方”号运载火箭将宇航员尤里·加加林送入太空,成为第一个进行载人航天活动的国家,在太空竞赛方面再赢美国一局。

      美国人在震惊之余,意识到正是由于政府对航天事业的轻视使自己处于下风,并立即着手制定雄心勃勃的太空计划。美国首先进行了“水星”载人飞船计划,进行了几次亚轨道载人飞行,虽说这远远比不上苏联几艘“东方”飞船的近地轨道飞行,但也在一定程度上平息了美国公众对政府航天计划接连失利的不满。随着1961年5月,热衷于航天竞赛的约翰·肯尼迪总统提出执行“阿波罗”登月工程,美国又发射了几艘带有技术探索性质的“双子星”飞船,为“阿波罗”工程做铺垫,“双子星”的成功意味着美国在科技与财力方面的优势开始显现出来。而同一时期,在完成“东方”飞船发射计划后,苏联的航天技术官员们认为应脚踏实地地发展空间轨道站,以实现宇航员的长时间在轨,但苏联领导层尤其是赫鲁晓夫更看中发射宇宙飞船的政治意义,在他的要求下,苏联航天部门发射了2艘“上升”飞船,其中上升2号的宇航员进行了世界上首次太空行走。接着,苏联也秘密地开始了自己的登月计划,采用的技术方案与美国的阿波罗-土星系统如出一辙,为此研制了一种勘与美国土星5号火箭相媲美的H-1巨型火箭,但这种火箭在4次试射中惨遭失败,使苏联的载人登月计划最后夭折。而美国的阿波罗工程则进展基本顺利,1969年阿波罗11号飞船成功地登陆月球,标志着美国在登月竞赛中大获全胜。

      进入1970年代,美苏关系开始逐渐缓和,双方也在反思一个问题:那种只追求政治利益的航天活动是否有真正价值。1975年,一艘美国的阿波罗飞船与苏联的联盟飞船在太空轨道进行了对接,这标志着双方对抗性的太空竞赛告一段落。在整个70年代,双方将注意力转移到了具有实际科技经济意义的深空探索和建设空间站上。

      首先苏联从1971年开始,接连发射了7座“礼炮”系列空间站,开创了宇航员长时间在太空生活工作的先例,是世界载人航天史上的重要里程碑。1986年苏联又发射了新一代空间站“和平”号,这座当时世界上最大最先进的空间站为宇航事业做出了重大贡献,先后接待了数以百计的宇航员进站工作,并创造了人类在太空连续生活时间的纪录,在其近20年的运行过程中一直是苏联/俄罗斯大国尊严的象征。

      美国在70年代初也发展了自己的“天空试验室”,但由于发射时出现的意外,使“天空试验室”一直带伤运行,在它短暂的生命周期中只接待了3批宇航员,但也取得了不少重要的科技研究成果。

      为了支持大型空间站的运转,需要不断地发射载人和运货航天器前往空间站,苏联采用的是发射一次性飞船的方法,这种方法耗资巨大。因此美国从1972年开始研制一种使用灵活、费用低廉的天地间往返运载器——航天飞机,作为未来大型空间站的运输工具。1981年4月12日,在加加林首次遨游太空20周年的纪念日,美国发射了“哥伦比亚”号航天飞机,这是人类太空事业的又一项重大成果,因为从理论上讲,即使是没有经过特殊训练的普通人也可以搭乘航天飞机飞上太空,而且航天飞机和载人飞船相比具有更大的灵活性。一时间,世界上出现了航天飞机热,英国、德国、日本、欧空局等都提出了自己的航天飞机计划,1988年苏联发射了“暴风雪”号航天飞机,和美国航天飞机相比,“暴风雪”号具有很多独特的优点。但1986年“挑战者”号的爆炸使人类意识到自己的技术可靠性还没有想象中那么强,载人航天活动一时陷入低谷。

      1980年代末期,世界局势发生了天翻地覆的变化,苏联由于长年开展军备竞赛和大规模的航天计划而国力透支,加上社会、民族等等尖锐的矛盾,终于轰然倒下。冷战几乎在一夜间结束了。世界战略格局的变化促使各国开始调整自己的航天计划,俄罗斯经济情况恶化,被迫放弃了大部分航天活动,只能勉强维持原有水平。美国则在1990年代初期停止了浩大的“星球大战”计划和“自由”号空间站计划。从1993年开始,美国联合俄罗斯、欧空局和日本等国着手建设“阿尔法”国际空间站,这标志着载人航天工程从冷战时期以政治与军事对抗为目标转变为着眼于国际合作和获取实际科技经济利益的新阶段。

      它山之石,可以攻玉。回顾40年来美苏两国的载人航天活动,对中国具有很大的借鉴价值,首先载人航天是提升国家形象与地位的重要途径,同时在科技、经济和军事方面都有重大意义;其次,载人航天活动是一项耗费巨大的工程,必须量力而行,那种单纯追求政治宣传的铺张的航天发射只会拖垮国家经济。

      力量·形象·威慑

      一个国家的力量包括经济力、科技力、军事力和政治力,其中经济力是社会生活的根本基础,科技力是国家发展的发动机,军事力是国家对外交往的强大后盾,而这最后一项政治力或称政治影响力则是国家力量构成中最复杂最微妙的,它包括国家的威望、在国际事务中的发言权、盟友的数量和力量、缔结盟友的能力、文化影响力等等。政治力的强弱首先取决于经济力、科技力、军事力,但同时也与国家的人口、地缘和历史传统有关,拥有强大政治力的国家往往可以不战而屈人之兵。政治力的养成不是一朝一夕的事情,如何最大限度地将国家的实力转化为政治影响力也需要高度的技巧。在当今国际社会中,我们可以看到某些国家由于精心地运筹折冲,获得了超出自身真正实力的政治力,比如法国并没有日本和德国的经济力量,也没有俄罗斯那样强大的军事实力,更没有美国那种全球力量投放的能力,但法国充分利用其联合国常任理事国、欧洲核心大国和历史上的殖民大国的多重身份,在欧洲、非洲、中东等地区事务上拥有很大的发言权。而值得玩味的是,法国也是一个公认的航天大国。

      对于中国来说,进行航天活动尤其是载人航天活动不失为一种提升国家形象,增强政治影响力,建立强大而可靠的国家威慑力的好方法。首先,载人航天活动具有很强的象征意义。载人航天工程从设计制造运载火箭、宇宙飞船到建立完善的发射场地和测控网络,几乎涉及到所有的国民经济部门,是一个国家工业技术能力的缩影,而工程的进度和花销又能反应出这个国家的管理能力。可以说航天工业的水平高低一定程度上标志着一个国家的现代化程度。因此,中国成功地进行载人航天发射,象征着我们这个曾经贫穷落后的农业国正在向先进的工业国家转变,这对提升中国的形象有很大的好处。

      其次,和其他显示力量的方法相比,进行载人航天活动在道义上无懈可击,在政治上能争取主动。举行军事演习、核试验、导弹试射、派遣舰队出访、向海外直接派兵都可以显示国家力量与决心,但这些方法都有过于强烈的对抗色彩,若处置不当则容易被指为挑衅和恫吓,在道义上和政治上会处于被动,甚至引起对方的激烈反应使威慑失效。由于载人航天发射具有很大的军用潜力,对潜在对手而言是一种强大的战略威慑,在危机关头可起到敲山震虎的作用。而载人航天的直接目的是科学探索,所以进行这种活动在道义上和政治上都处于有利地位,从这个意义上说,中国可以通过巧妙地安排发射时间,使自己的载人航天行动变成一种向对手传达政治信号、显示决心的外交“武器”,这种“武器”又可以避开所谓中国威胁论的指责。

      第三,载人航天发射活动对其他国家的领导层、普通民众和本国民众都有很大的心理影响。载人航天发射活动可以说是地球上最壮观最激动人心的科技活动。硕大无朋的运载火箭喷吐着巨焰和翻滚的浓烟,雷鸣般地从发射台上缓缓升起,明亮的火光像利剑一样划破黑暗的夜空,仿佛天神降临人世。在轨道上运行的宇宙飞船外表涂着醒目的五星红旗,黑眼睛黄皮肤的宇航员们微笑着向千里外幽蓝恬静的地球招手……所有这一切场面通过电视转播传遍世界,对外国观众有巨大的感染力,无论是普通民众还是领导人都会由衷地感叹机械文明的强大,并自然而然地对进行载人航天发射的国家产生羡慕和钦佩之情,这种钦敬将对他们的决策行为产生微妙的影响。这就是航天活动的心理影响力。对于本国民众来说,国家成功地将宇航员送入太空将激发他们的民族自豪感和自信心,而且这种航天活动是无比生动的科学普及课程,十分利于培养民众尤其是孩子们热爱科学的精神,这也可以从长远上提高国家的科技力。

      中国作为一个崛起中的国家,必然将在21世纪的世界上占有一定的地位,到2050年成为中等发达国家的目标能否顺利实现很大程度上取决于能否获得一个长期稳定的周边安全环境。冷战结束后,国际力量对比发生了根本性变化,美国国力相对大大增强,再加上9·11事件的刺激,使国内单边主义抬头,与此对应的是美国在中国周边的一些盟国趁机动作,试图借力打力捞取更多的政治和安全利益,这使得中国的安全环境在近年来呈现这样一种态势:在整体战略和外交空间不断扩大的同时,在某些国际问题上如朝鲜核问题、南海纠纷、日本国内保守势力抬头等等都遇到了严峻挑战甚至威胁。为了应对这种挑战,中国需要加强自己的战略威慑力量,全方位地遏制潜在对手的野心。发展载人航天技术,抢占科技和军事制高点是一种行之有效的方法。

      军事力量倍增器

      航天技术从发展之初就和军事应用有着极为密切的联系,实际上到目前为止世界各国发射的数千个航天器中,70%是军事航天器或军民两用航天器,其中又以美俄两国发射的侦察卫星和军用通信卫星为主。这两个航天超级大国都已经成立了兵种级别的军事航天部队。据统计,美国情报部门获取的各种情报中绝大部分是由美国国防情报局的间谍卫星搜集的,而美军80%的军事通信业务由通信卫星承担,航天器已经成为美军军事网络中最重要的环节。可以说,各军事强国都在努力地占领外太空这一战略制高点。而载人航天器相对于无人航天器的灵活性和自主性,使其具备了多种军事潜力,发展军民两用载人航天器将成为中国军事力量的倍增器。

      在现代战争中,C3I系统即控制、通信、指挥、情报系统的作用显得尤为突出。而C3I系统中一个重要的环节就是空中预警机。1982年中东贝卡谷地之战中,以色列的E-2C“鹰眼”预警机使用机载远程雷达先期探测到叙利亚空军的米格机群,然后从容地引导指挥己方的F-15、F-16拦截攻击,结果在一天之内击落对方70余架战斗机,而己方无一伤亡。1991年的海湾战争中,美国的E-3“望楼”和E-8“联合星”预警机不停地在伊拉克上空巡弋,指挥美军战斗机自始至终牢牢地掌握着制空权,为战争的胜利立下汗马功劳。这两个例子充分说明了空中预警指挥系统的重要性。但预警机也有它的局限性,首先预警机的航程有限,一般留空时间不超过8个小时,需要几架飞机轮番上阵;其次预警机的雷达作用范围还是受到地球曲率半径的影响;而且预警机大多由运输机改装而成,因此容易受到对方战斗机和防空导弹的攻击,需要严加保护。相比之下,如果将载人航天器作为太空预警指挥所则没有这些缺点。目前宇宙飞船一般可在近地轨道上停留一周,航天飞机可以停留两周,而空间站更可以10年20年地运转下去。而且由于载人航天器飞行速度快,活动空间高,对方除非也使用同等水平的航天器否则几乎无法威胁到我方。在宇宙飞船上安装大功率通信指挥系统、红外与雷达探测系统和高速辅助计算机,再派遣经过航天训练的军事指挥员驻船工作,就可以组建起高效的太空指挥站。若再与数据中继卫星和通信卫星相配合,还可以起到太空通信中转站的作用。

      在轨道上运行的航天器一天之内可以环绕地球许多次,而且由于国际法允许航天器飞越其他国家领空,因此十分适合执行军事侦察和情报搜集工作。目前世界各国主要使用各种人造卫星来完成此类任务,其中包括使用可见光或红外光的照相侦察卫星、雷达侦察卫星、气象侦察卫星、海洋监视卫星、电子监听卫星等等。这些卫星虽然能完成多种任务,但也有其固有的缺陷,比如由于卫星的体积重量有限,因此搭载的设备和燃料的数量都不可能太多,作业能力自然受到限制。卫星的工作基本上按固定程序进行,使用灵活性比较差,在轨机动能力低,容易遭到敌人破坏。如果使用载人航天器执行侦察任务,则具有很多优点,首先有人驾驶的航天器运载能力很强,可以携带重型侦察设备,几年前美国一架航天飞机曾装载一部大型高精度合成孔径雷达升空,在一周时间内对地球表面进行了详细的扫描,从而获得了历史上精度最高最完整的地表雷达图象,这种图象可用于巡航导弹的制导系统,对增强美军打击能力意义重大。如果不使用航天飞机上的大型货舱,无人卫星是不可能完成这种任务的。其次,有人驾驶的航天器灵活性很高,可以在宇航员的操纵下随机应变,对突然出现的地面目标进行监视,并可直接判断汇总各种情报,时效性远远高于侦察卫星,因此常在突发危机时用来执行紧急侦察。历史上,无论是苏联的“礼炮”“和平”空间站还是美国的航天飞机都曾多次执行对热点地区的侦察任务。中国的神舟宇宙飞船如果需要,也可以在指令舱外安装侦察照相机,当周边发生军事冲突时进行太空监控。

      载人航天器还有一个重要的军事用途,那就是直接作为太空战斗机或太空轰炸机等天基武器系统攻击敌人的卫星和地面目标。如前所述,各类卫星已经成为军事强国C3I系统的核心环节,因此如果能在战争爆发初期,就迅速破坏敌方的卫星网络,则可以在战争中占得先手。1960年代,苏联军方发展了反卫星卫星,即所谓的杀手卫星,可以采用同归于尽的方式摧毁敌人的航天器。1985年,美国曾使用F-15战斗机在万米高空发射反卫星导弹,击毁了一颗废弃的低轨道通信卫星。从1970年代起,苏联一直在秘密研制可以从地面攻击太空飞行器的粒子束武器,美国的星球大战计划中一项关键性武器就是天基化学或核爆炸激光炮。这些武器都可以用来装备宇宙飞船和航天飞机。1984年,美国航天飞机在几百公里高的太空成功地跟踪捕获了一颗失控的国际通信卫星,并在太空中将其修好,这一事件震惊了苏联,因为这表明美国人实际上已经具备了捕捉摧毁敌人卫星的能力。苏联在1980年代初期,也设想了一种太空航空母舰,它实际上是一座小型空间站,站上有多座对接口,可对接容纳数艘单人驾驶的小型飞船,而飞船上则装备有强大的动能武器用来攻击敌人的航天器。也许在不久的将来,太空中真的会出现科幻电影中的空间大战。从太空中直接袭击敌国本土也是载人航天器的潜在军事能力,以航天飞机为例,它可以在货舱中携带数吨重的核弹头,以3万公里的时速飞行,在1小时内可以到达地球上任何地点,按照目前的防空技术水平是根本无法拦截的。因此,当载人宇宙飞船或航天飞机在设计之初就可以考虑采用模块化设计,平时飞船上搭载用于科研目的的设备模块,到了战争时期则可以迅速换装作战装备模块,摇身变为具有强大战斗力和威慑力的战略武器。

      中共十六大提出紧跟世界军事潮流,启动新军事变革,实现军队战斗力的跨越式发展。那么如何紧跟世界潮流呢?如果按部就班地发展常规武器,将先进军事国家十年甚至二十年前做过的事再做一遍的话,那我们就将永远处于跟随者和落后者的地位。要实现战斗力的跨越式发展,就必须拥有超常规的新概念武器与新概念部队,将其作为我国维护统一、抵抗外国势力干涉的“杀手锏”。组建我国的军事航天部队是大幅度增强我军战斗力的一条捷径。由于我国航天工业起步早、起点高、投入大,因此与世界先进水平相差不多,在某些领域还处于领先地位,利用这种资源研制强大的军用航天武器尤其是载人航天武器并不困难。我军的潜在对手对卫星等航天器的依赖性很强,而卫星也恰恰是其作战网络中最薄弱的环节,如果在未来一旦反侵略战争爆发,我军可使用新型载人航天武器在开战之初就摧毁敌人的天基C3I网络,可以起到“点穴战”的功效。

      一只下金蛋的鹅

      就在去年,一条引人注目的消息传遍了全世界,一位美国富商在支付了2000万美元后,搭乘航天飞机登上了“和平”号空间站生活了一周,成为历史上第一位进行太空旅游的乘客。人们在惊叹这位商人的富有之余,也许会问除了让地球上的人掏钱遨游寰宇之外,载人航天工程是否还有其他的经济技术价值呢?事实上,载人航天工程可以利用外层空间的特殊环境,进行各种科学探索和经济性生产,简而言之,就是一只会下金蛋的鹅。

      首先,让我们来看一组关于“阿波罗”工程的数据。阿波罗工程从1961年5月开始,到1972年12月结束,曾有2万个企业、200多所大学和研究机构参与其中。阿波罗工程在经济上使美国经济增长率提高了2个百分点,物价指数下降2%,创造了80万个就业机会。美国1958年的国民收入为4062亿美元,到1970年增长到9046亿美元,10年间翻了一倍多,这其中相当程度上是阿波罗计划刺激的结果。此外,阿波罗工程中取得的大量科技成果后来被广泛应用在国民经济的其他领域,而美国宇航局在执行阿波罗计划中取得的管理经验也被后来许多大型工程所借鉴。从上述数据中我们可以看出,载人航天工程是经济发展的强劲动力。

      具体而言,载人航天工程在经济科技方面有以下几种用途:

      科学技术探索。地球表面的大气层虽然保护着人类和全体地球生物不受恶劣的外层空间环境的伤害,但同时它也影响了人们对太空的研究,大气的折射作用会使地球上的天文望远镜影响扭曲,会吸收掉太空来的宇宙射线。要想更好地进行天文学和地球物理学研究,就必须脱离大气层的局限,将观测设备安装到人造卫星和宇宙飞船上,搬到外层空间去。从航天时代伊始,各类航天器就不断做出重大的科学发现。1980年代后期美国发射的哈勃太空望远镜是此类航天探测器的代表,而哈勃望远镜就是由航天飞机携带发射的,1990年代初,美国航天飞机还曾专门对哈勃望远镜进行过在轨修理。而且由于太空是一个高洁净环境,因此可以完成许多在地球上无法完成的科学试验。

      太空生产车间。太空的另一个重要特点就是重力极其微弱,在太空中流体内部因不同密度和不同成分而产生的对流现象完全消失,容器内壁对物体也没有摩擦和限制作用,因此在这种环境中可以观察到许多新的物理现象、化学现象、生物现象等,而且为半导体和蛋白晶体的生长、新型材料的加工制造、电泳生产、新型冶金等都创造了条件。载人宇宙飞船和空间站都可以作为太空车间使用。比如,在空间站里可以制造纯度极高的大块半导体晶体,单晶硅和砷化镓之类的半导体晶体是电子工业的基础,但地面上形成的半导体晶体块都很小,而且由于对流作用,晶体的纯度和均匀度都很差,一般只能有30%左右能用于工业生产,而在太空中生产的晶体则没有这些缺陷。在太空中另一项重要的生产加工领域是特种合金和特种材料的生产,在微重力条件下利用汽相合金加工的方法,会形成新的合金结构与特性,在太空中生产的滚珠轴承的寿命是普通轴承的5到8倍。

      太空制药厂。在太空微重力环境下,应用空间分离技术如电泳、等电聚焦、液相细分提炼等等,就可以在空间站里批量生产高纯度药物。美国航天飞机在执行太空试验时发现,太空中制造的药物比地球上制造的同种药物的纯度提高了5倍,而提纯速度提高了400到800倍,这意味着太空中一个月的药物产量顶得上地球上30年的产量。促红细胞生长素是一种可以挽救贫血病人的特效药,在地面上生产的这种药物每剂的价格高达3000美元,用来治疗血栓的尿激酶价格为1000美元,而如果在太空中生产这些药物则价格可以降低到原来的几十分之一,可以拯救无数负担不起高额药费的病人。

      太空育种站。中国多年来发射的返回式卫星和宇宙飞船中经常携带各种农作物的种子,这些种子被带到外层空间后经过宇宙射线的照射,基因结构发生了改变,再被带回地球进行选种后就可获得产量很高的新品种。在太空中遨游过的青椒种子可以种出比苹果还大的果实,而西红柿甚至能长到接近小西瓜的程度。

      中国的经济要保持近年来迅速发展的势头,利用科技拉动经济势在必行,积极发展载人航天技术,使之成为基础科学研究基地,新型材料、新型药物等高附加值产品的生产基地,将对我国的可持续发展具有重要意义。

      龙之升腾

      中国在新世纪刚刚开始的时候积极投身于凸显国家综合实力的载人航天工程,具有很强的象征意义,当五星红旗在太空轨道上出现时,人们看到是一个具有古老传统同时又朝气蓬勃的国家在东方崛起,回首我们那些刻骨铭心的苦难和屈辱,也许并不能仅靠一次震撼世界的航天发射来洗刷,但至少神舟的升空代表了一种希望,一种华夏神州走向现代化走向再次辉煌的希望。它是全体中国人在新世纪发出的自信自豪的宣言。

      让我们为神舟飞船成功地飞往太空喝彩!

      让我们为那些在大漠戈壁中默默奉献一生的航天人喝彩!

      让我们为龙之升腾喝彩!
