To what degree can a computer achieve intelligence?The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.
If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.
He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child’s age returns, “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com.
Some scientists believe that by joining the many systems of the Internet, an artificial(人工的) being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However, if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. Artificial Intelligence, he must solve two problems.
The first is that computers find it difficult to read web pages because the files(文件) are sorted in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.
Another problem is that while Smarter Child can process(處理)information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.
【小題1】From the text we can infer that www.intellicast.com is a website          .

A.which is specially designed to help Smarter Child
B.where we people can find Smarter Child
C.where weather forecasts are made
D.which is about artificial intelligence
【小題2】It is probably most difficult for Smarter Child to         .
A.tell us how to spell a difficult word
B.tell us how the American government is run
C.provide us with a famous poem by Shakespeare
D.learn the ability to tell right behaviors from wrong ones.
【小題3】Which of the following is TRUE according to the text?
A. Smart Child has his own memory bank big enough for all kinds of information.
B. A.I. Artificial Intelligence is probably the name of a film about a boy-computer.
C. Smart Child can recognize different files and find information needed on his own.
D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.
【小題4】Which of the following is the best title for the passage?
A.A New Web ChildB.Smarter Child
C.The Future of InternetD.Intelligence Development


【小題1】C
【小題2】D
【小題3】B

China may be the world's most populous country ,and it won the most gold medals at the 2008 Summer Olympics in Beijing. But its prowess at soccer is lamentable. China is ranked 84th in the sport's world standing.

Chinese are huge soccer fans, and hundreds of millions are expected to tune in to the World Cup, with all the matches broadcast live on public TV. But this time the Chinese don't have their own team to root for.

"Chinese have a reputation of being good at math, but they have trouble explaining why a population of 1.3 billion cannot produce a winning 11-member soccer team," said Xu Guoqi, a history professor at the University of Hong Kong. Journalists and soccer fans offer a number of reasons, most often money issues, politics, corruption(腐敗)and culture, and sometimes a combination of the four.

Even though China now boasts wealthy companies and individuals who could sponsor(贊助) teams, there is little support as long as Chinese teams are perceived as perennial losers. "This is a very bad circle," Ma said. "No results, no money. No money, no results."

Few Chinese children are playing soccer. Some sports journalists and fans attribute the lack of interest partly to schools de-emphasizing sports in general and the lack of playing venues in the country's dense urban areas. "What can Chinese kids do?” said Fan Huiming, 61, a Chinese soccer fan who grew up watching matches at Beijing's Workers' Stadium, which was built in 1958 near his childhood home. "If they play soccer, the ball may fly directly into the glass of someone's home."

For young people, soccer has largely been eclipsed by basketball, thanks in part to Chinese NBA players who are treated like rock stars. Journalists and fans say NBA's aggressive campaign of marketing and merchandise in China has helped swell the popularity of basketball. By comparison, they noted that international soccer does not even have an office in China.

Rowan Simons, a Briton who came to China more than two decades ago and discovered he wasn't able to play weekend soccer, has been on a campaign to popularize the sport here. Simons said the main problem is that soccer elsewhere has traditionally started as a series of neighborhood clubs, but in China, "there's virtually no football at community level".

"Football in China can only succeed if it's a grass-roots activity organized by the people," he said.

This time the Chinese don't have their own team to root for in the World Cup because__________.

A.China is ranked 84th in soccer 's world standing.

B.they are angry about why China cannot produce a winning soccer team.

C.the Chinese huge soccer fans support other soccer teams.

D.the Chinese soccer team is not capable to go as far as the final part of the World Cup.

Why are few Chinese children playing soccer?

  A.No results, no money. No money, no results.

B.If the footballs fly directly into the glass of someone's home,they’ll be criticised.

C there is little support from wealthy companies and individuals sponsoring teams.

D.schools don’t pay much attention on sports and they lack playing venues in dense urban areas.

The underlined word“eclipsed”in the six paragraph can be replaced by      .

  A.occupied.                      B.beaten.                  C.led.                     D.compared.

According to Rowan,what can be inferred ?

  A.NBA players are more popular than soccer players in China.

B. The future of Chinese football is rather promising.

C. Chinese football should get into the life of ordinary people to survive.

D.Grass-roots Chinese football players can be popular .

The Olympic Games are seen as the greatest test of an athlete’s ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began.
In the early years, athletes ate mushrooms(蘑菇)and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping(服用興奮劑).
Just last month, Britain’s top sprinter(賽跑選手) Dwain Chambers and several American athletes tested positive(呈陽(yáng)性)for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how to test for it.
“We’re like cops(警察)chasing criminals—athletes are always adapting and looking for areas we haven’t investigated,” said Jacquew de Ceaurriz, a French anti-doping expert.
Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson.
He broke the 100 meters world record in winning gold at the 1988 Seoul(漢城)Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action—only to be found positive again and banned forever.
China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes—seven of them swimmers—tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again.
Experts are also worried that doping can damage a person’s health. It is believed to increase the risk of liver and kidney(肝腎)diseases, and women may experience reproductive(生育) problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene(基因)technology.
“For the moment, genetic doping does not exist,” said de Ceaurriz. “Even in 10 or 15 years it will not be done easily—the scientific community(界)will not let it happen.”
(  ) 60. Which of the following is not the way that some athletes cheat to their better sports achievements?
A.Eating mushrooms.        B Taking drug THG.
C. Taking genetic doping.       D. Eating plant seeds.
(  ) 61. How many countries are mentioned in the passage in which there were athletes doping?
A. Two.                 B. Four.                C. Sic.                  D. Eight.
(  ) 62. We can infer from the passage that ____.
A.scientists get a lot of information about drugs before the athletes take doping
B.taking doping will never happen again because of the serious test
C.few athletes used drug cheats before the first drugs test was carried out at the 1968 Olympics
D.problems with drug cheats are still serious though they are severely tested
(  ) 63. Which statement of the following is true?
A.Many police are sent to chase criminals of taking doping during the Olympic Games.
B.The drug test was carried out until the 1968 Olympics.
C.There is the possibility that women athletes taking doping will give no birth to a child.
D.Ben Johnson was banned from sports forever for being tested positive for drug use at the 1988 Seoul Olympics.

Tickets for the 2014 World Cup in Brazil have gone on sale, with fans able to apply on FIFA’s website. FIFA is expecting a similar demand to that in Germany 2006, when there were about seven applicants for every ticket of the 64 matches. And now around 3.3 million tickets will be available for the matches in 2014.

    Tickets will range in price from £58 for first-round matches to £632 for the final at Maracana Stadium in Rio de Janeiro. Brazilian citizens over 60, local students and members of some social programs can purchase tickets for £15.

“It’s always difficult to predict,” said FIFA marketing director Thierry Weil. “But I truly believe that it will be more similar to what happened in Germany than in South Africa in 2010.”According to FIFA, the 2006 World Cup was attended by more than 3.3 million fans. Almost two million tickets were sold to the general public in South Africa, although the number of applications during the first ticketing phase was significantly lower.

    All applications made before 10th October 2013 will enter a random selection draw if there are not enough tickets available to fulfill all requests. The sales of the leftover tickets will begin on 5th November on a first-come, first-served basis. Another phase will begin on 8th December after the draw is made. The tournament begins on 12th June, with Brazil playing the opener in Sao Paulo.

    A study on the price of World Cup 2014 looked at the ticket prices and the cost of travelling to Brazil and found that our English fans face hotel costs of between £46 and £797 a night, while packages range from £2,999 to £14,999.

1.How much should a Brazilian student pay for the opening match?  

A.£15         B.£58        C.£112        D.£632

2. From the passage we know that Thierry Weil_______.

B. feels worried about the sales of the tickets for Brazil 2014

C. holds the belief that Brazil 2014 will be the greatest world cup

D. believes that more fans will attend Brazil 2014 than South Africa 2010

3.What will FIFA do if there are not enough tickets available for requests before Oct.10, 2013?

A. They will sell the spare tickets to the applicants.

B. They will sell on a first-come, first-served basis.

C. They will choose the applicants based on a random selection draw.

  In 1990 a report was published about what the earth might be like 20 years from then on. 71 According to the report,the picture of the earth in the year 2010 is not a pleasant one. 72 The population could be as large as 6300 million,almost 2150 million more than in 1985.More people would move into cities ,especially cities in developing countries.Cities like Cairo and Jakarta probably would each have 15 million by then.

   73 Farmers will grow 90% more food than they did in 1985,but most of the increase would be in countries that already produce enough food for their people. 74 Poor farming ways are destroying large areas of crop land,changing farms into deserts.More farmland is lost as cities become larger and more houses are built.Air pollution will get worse as industrial countries burn more coal and oil.Many of the world's forests could disappear as more and more trees are cut down.Energy will continue to be a serious problem. 75 They only workde out the situation that exists today.By changing the situation,by settling the problems,the picture can be changed.There is still time for the nations of the world to work out a plan of action.But they warned that waiting too long to make de cisions would greatly reduce the chances of success.
