A new study has found that it may be possible to train people to be more intelligent,increasing the brainpower they had at birth.
Until now,it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught(though people can raise their grades on tests of it by practicing).
But in the new study,researchers describe a method for improving this skill,along with experiments to prove it works.
The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence,so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game,in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items,monitor ongoing performance,manage two tasks at the same time and connect related items to one another in space and time.
The four groups experienced a half-hour of training daily for 8,12,17 and 19 days,respectively. To make sure they were not just improving their test-taking skills,the researchers compared them with control groups that took the tests without the training.
The results, published Monday in The Proceedings of the National Academy of Sciences,were striking. Improvement in the trained groups was a lot greater. Moreover,the longer they trained, the higher their scores were. All performers,from the weakest to the strongest,showed significant improvement.
“Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops,”he added,“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”
67.The researchers thought the key to improving the intelligence was ______________.
A.memorizing telephone numbers
B.improving working memory
C.training in concentration
D.recalling a card
68.The following aspects of the training help increase intelligence EXCEPT___________.
A.ignoring irrelevant items
B.monitoring ongoing performance
C.managing two tasks at the same time
D.using previous experience
69.When the experiment was conducted,the researchers______________.
A.trained the four groups for the same period of time
B.only made comparisons between the four groups
C.compared the four groups with control groups
D.trained the four groups together
70.By writing the article,the writer intends to ______________.
A.inform the readers of a new study
B.call on people to be trained to increase intelligence
C.prove one’s born brainpower can be improved
D.tell people the improved intelligence will last forever
Some people believe that international sports create goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true: that international competitions encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourage international brotherhood. Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused mainly by minor national competitions.
One country received its second-place medals with visible indignation(愤慨)after a hockey final. There had been noisy scenes at the end of the hockey match, the loser’s objection to the final decision. They were sure that one of their goals should not have been disallowed and that their opponents’ victory was unfair. Their manager was very angry and he said, “This wasn’t hockey. Hockey and the International Hockey Federation are finished.” The president of the Federation said later that such behavior could result in the suspension(停赛)of the team for at least three years.
The American basketball team announced that they would not give up the first place to Russia, after a disputable end to their competition. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player popped the ball into the basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury discussed the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals.
Incidents of this kind will continue as long as sports are played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in non-national teams, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism(爱国主义).

The results of the US/NATO bombing Yugoslavia are to be judged by history. I shall not be the one to do this. But being in the center of actual events that are creating that history, I cannot stay away from what is going on in my country.
First of all, the main aim of the bombing was to prevent a human suffering in Kosovo. Today, after many days of frequent bombing, that aim is more distant than before. The bombing only brought tens of thousands of people running away from their homes, not to mention the large number of the death and injury, buildings and factories. Suppose that the US/NATO really had a wish to prevent the human suffering, they should realize by now how wrong they were when they thought the bombing would solve the problem.
So, what’s left? Back off or ground troops? But who is going to join the ground troops? It would take at least 200,000 armed soldiers, not the 20,000 that the US/NATO have prepared in Macedonia. It should also be clear that the Serbs(塞族人) will not give up on Kosovo.
I live under continuous bombing for more than a week now, and it doesn’t frighten me anymore. I don’t turn to the shelter at the sound of warning. It’s the thought of ground troops that frightens me. Vietnam would seem like a picnic compared to a bloodshed(流血事件) in Kosovo if the ground troops appear. Is that what the US/NATO wants?
72. Which of the following statements is true?
A. The US/NATO really intends to stop the human suffering.
B. The result of the war will be judged by people in Kosovo.
C. The bombing made tens of thousands of people homeless.
D. The continuous bombing will make the Serbs give up on Kosovo.
73. The writer is _____.
A. an American reporter B. a Chinese reporter
C. a Macedonian D. a Yugoslavian
74. What worries the writer most?
A. The continuous bombing. B. The coming of the ground troops.
C. The sound of bomb warning. D. The idea of ground troops.
75. What is the writer’s attitude towards the bombing in Kosovo?
A. It is the US/NATO’s duty to defend Kosovo.
B. It is wrong to solve the problem by bombing Kosovo.
C. The aim of bombing Kosovo is to stop a human suffering.
D. The bombing can solve the problem of Kosovo.

The Internet will open up new vistas (前景), create the global village——you can make new friends all around the world. That, at least, is what it promised us. The difficulty is that it did not take the human mind into account. The reality is that we cannot keep relationships with more than a limited number of people. No matter how hard the Internet tries to put you in communication, its best efforts will be defeated by your mind.
The problem is twofold(双重的). First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest in then. We invest a lot in a small number of people and then distribute what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline until eventually it dies into “someone I once knew”.
This is not, of course, to say that the Internet doesn’t serve a socially valuable function. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.
In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see them, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The Internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.
1.The number of friends we can keep relationships with is decided by__________.
A. the Internet B. the time we have C. the place we live D. the mind
2.The underlined word “engagement” in the second paragraph probably means “__________”.
A. appointment B. connection C. interview D. agreement
3.The author holds the view that___________.
A. the Internet helps to keep in touch with friends far away
B. the Internet determines the quality of social relationships
C. the Internet greatly increases the size of social circles
D. the Internet is of no value in social communication
4.What will the author encourage us to do?
A. To keep in touch with old friends when we have moved away.
B. To chat with friends often on the Internet.
C. To make more new friends face to face.
D. To stop using the Internet to make new friends.
5.What is the author’s attitude towards the use of the Internet to strengthen relationships?
A. He thinks it useless B. He is hopeful of it.
C. He approves of it. D. He doubts it.

第三部分 阅读理解(共20小题;每小题2分,满分40分)
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
A
Too often we accuse others of not listening, pretending that we ourselves are faultless, yet in our hearts we know that many of the mistakes we make come about because we haven’t listened carefully enough. We get things wrong because we haven’t listened carefully enough. We get things wrong because we haven’t quite understand what someone meant when they were talking to us. Anyone who has ever taken the minutes of a long meeting will know how hard it is to remember---despite the benefit of notes---exactly what everyone says. But success depends on getting right---and that means listening.
Listening is not the same thing as hearing; it is not an effort actively. It demands attention and concentration. It may mean quizzing the speaker for additional information or for clarification---it is always better to ask than to continue regardless and get things wrong. However, if you allow your mind to wander onto something else, even for a few minutes, you’ll miss what the speaker is saying---probably at the very moment when he or she is saying something critical. And not having heard, you won’t know you’ve missed anything until it’s too late.
The most common bad habit we have is to start thinking of what we are going to say about the subject long before the other speaker has finished. We then stop listening. Even worse, this often adds rudeness to inattentiveness, as once you have decided what to say there is a fair chance you will interrupt to say it. Good listeners don’t interrupt. In fact it is often worth explaining the main idea of what you have listened well.
Above all, be patient and accept that many people are not very good communicators. It’s helpful to remember that the ways people move and position themselves while they are speaking can reveal a great deal about what they are saying. Equally important you should put yourself in the other person’s place, both intellectually and emotionally; it will help you to understand what they are getting at and form a response. But don’t be too clever. Faced with a know-all, many people keep quiet because they see no point in continuing.
51. Which is the best title for this passage?
A. Don’t be too clever B. Be a good listener
C. Don’t miss anything critical D. Think of the speaker
52. In the last paragraph, the underlined sentence “…what they are getting at…” means ______.
A. what they imply B. what they like C. what they attack D. what they achieve
53. According to the passage, which of the following is the writer’s opinion?
A. If you want to be a good listener, you should be very clever and emotional.
B. Speakers won’t continue talking when their listeners explain what they’ve heard.
C. If you don’t want to get things wrong, it’s important to be a good listener.
D. It’s hard to be a good listener because listening tests you on your intelligence.
54. What is the lesson we can learn from this passage?
A. Don’t accuse others of not listening while talking with them.
B. Don’t get anything wrong if you miss what the speaker is saying.
C. Listening inattentively may cost you the loss of your success.
D. Think carefully of what you’re going to say before the speaker finishes.
