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

Steven Jobs, the designer of Apple Computer, was not clever when he was in school. At that time, he was not a good student and he always made troubles with his schoolmates. When he went into college, he didn’t change a lot. Then he dropped out（退学）. But he was full of new ideas.
After he left college, Steven Jobs worked as a video game designer. He worked there for only several months and then he went to India. He hoped that the trip would give him some new ideas and give him a change in his life.
Steven Jobs lived on a farm in California for a year after he returned from India.
In 1975, he began to make a new type of computer. He designed the Apple Computer with his friend in his garage. He chose the name “Apple” just because it could help him to remember a happy summer he once spent in an apple tree garden.
His Apple Computer was so successful that Steven Jobs soon became famous all over the world.
He often said, “I live in order to change the world, there aren’t any other reasons. The only way to have a great achievement is to love your own career. If you can’t find your favorite career, go on looking for it and never give up.”
This is Steven Jobs, though he is dead, his spirit and achievements still influence our lives.
【小题1】Steven Jobs was not a good student in school because he ________.

                                    In Japan many workers who work in large corporations have a guarantee of lifetime employment. During their employment, they will not be laid off during recessions(经济萧条) or when the tasks they perform are taken over by robots. To some observers, this is what they call capitalism at its best, because workers are treated as people not things. Others see it as necessarily inefficient and they also believe it cannot continue if Japan is to remain competitive with foreign corporations by being more concerned about profits and less concerned about people.

　　Defenders of the system argue that those who call it inefficient do not understand how it really works. In the first place not every Japanese worker has the guarantee of a lifetime job. The lifetime employment system includes only “regular employees”. Many employees are not included in this category, including all women. All businesses have many part-time and temporary employees. These workers are hired and laid off during the course of the business cycle just as employees in the United States are. These “irregular workers” make up about 10 percent of the non-agricultural work force. Additionally, Japanese firms keep some flexibility through the large-scale use of subcontractors（转承包者）. This practice is much more common in Japan than in the United States.

　　The use of both subcontractors and temporary workers has increased remarkably in Japan since the 1974-1975 recessions. All this leads some people to argue that the Japanese system is not all that different from the American system. During recessions Japanese corporations lay off temporary workers and give less business to subcontractors. In the United States, corporations lay off those workers with the least seniority(资历). The difference then is probably less than the term “lifetime employment” suggests, but there still is a difference. And this difference cannot be understood without looking at the values of Japanese society. The relationship between employer and employee cannot be explained in purely contractual(合同的) terms. Firms hold on to the employees and employees stay with one firm. There are also practical reasons for not jumping from job to job. Most retirement benefits come from the employer. Changing jobs means losing these benefits. Also, teamwork is an essential part of Japanese production. Moving to a new firm means adapting to a different team and at least temporarily, possessing lower productivity and lower pay.

61.It is stated in the second paragraph that ____.

　　A. defenders themselves do not appreciate the system

　　B. about 90% of “irregular workers” are employed in agriculture

　　C. the business cycle occurs more often in Japan and in the U.S.

　　D. not all employees can benefit from the policy

62. During recessions those who are to be fired first in the U.S. corporations are ____.

　　A. regular employees                         B. part-time workers

    C. junior employees                            D. temporary workers

63. According to the passage, Japanese firms are remarkably different from American firms in that the former ____.

　　A. use subcontractors in larger amount

　　B. are less flexible in terms of lifetime employment

　　C. hold on to the values of society

　　D. are more efficient in competition than the latter

64. Which of the following does NOT account for the fact that a Japanese worker is unwilling to change his job?

　　A. He will probably be low-paid.

　　B. He will not be able to possess some job benefits.

　　C. He has got used to the teamwork.

　　D. He will be looked down upon by his prospective employer.

65. Which of the following can be the best title for this passage?

  A. The guarantee of employment in Japan

  B. The consequence of the Japanese system

  C. The advantages of lifetime employment in Japan
