Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a

day in the not-mo-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of travel in the foreseeable future.

The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.

Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion(拥挤). One proposed solution to this problem is the automated highway system.

When the auto enters the highway system, a retractable(可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements.

The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wak for the buzzer(蜂鸣器) that will warn of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,400 to 2,000 vehicles that can be carried by a present-day highway.

One significant improvement in the future car may probably be ______.

A．its power source

B．its driving system

C．its monitoring system

D．its seating capacity

Having acknowledged receipt of the interview letter，you must prepare for the interview. Fi

rms usually take a good deal of trouble over interviews，and there may be three or more people present，which can be a little frightening. Very often the personnel officer will begin by some words of welcome and an invitation to you to tell them a little about yourself. This is really inviting you to repeat the information you have already supplied on the application form，and which they have already read，but it does have some point. It will put you at your ease，because at least you know all about your own level of achievement and can speak about it confidently. It helps them assess your ability to communicate and your serf-esteem. Some people have too high an opinion of themselves，some take an unduly pessimistic view of their achievements，while others have a nicely balanced assessment of their own abilities.

听力原文： The world's smartest adolescents in mathematics and science are in Singapore, a

ccording to a global survey of educational achievement. In the 3rd International Mathematics and Science Study, a 13 years old student from Singapore achieved the best scores in standardized tests of math and science that were administered to 287,896 students in 41 countries in 1994 and 1995. The survey suggests that science and math education is especially strong in the Far East. While behind those top scores, students from Australia earned higher marks in math than their counterparts in England, who in turn did better than American students. The study collected information on the students' teachers and homes. Not surprisingly, the highest-scoring students had well-educated parents or came from homes containing study-aids such as computers, dictionaries or even such elemental facilities as. desks. The study shows that boys generally did better than girls in science, but there was little difference between them in math. Boys scored better than girls in physics and chemistry. There were no sex differences in the life and environment sciences. In addition to being tested, students in the project were asked how proficient they thought they were in math and science. Students in some countries, such as Columbia and Kuwait, had an overly optimistic view of their skills. Meanwhile, some of the best students from Japan and Korea for example were needlessly pessimistic even though they did far better in math than almost all of other students.

According to the passage, which country's students scored the highest in math？

A．Singapore.

B．America.

C．Japan.

D．England.

第10题

Traditionally economics was dubbed the "dismal science" in response to the notion that sca

Traditionally economics was dubbed the "dismal science" in response to the

notion that scarcity is its foundation, and it constantly unsettles people with its

emphasis on the role that self-interest plays. It is difficult to raise a crop of

Line idealism from fields of self-interest, and to some, this is a dismal outcome.

(5) However, there is an optimistic side to economics: economists focus on market

exchange, where both buyer and seller emerge with greater wealth than they

were before, a positive-sum outcome. In contrast, many social scientists

outside of economics make heavy use of power models to interpret the world,

arguably a far more pessimistic way to view reality and power models tend to

(10) see interactions as zero-sum, meaning that any winning is balanced by a loss:

where one person improves his situation, it must come at the expense of

another whose situation has become worse. But one reason those who use power

models are not dubbed "dismal scientists" is that they are often utopian,

spuriously claiming that at some distant moment, all may win.

Which of the following statements concerning non-economists' view of economists can most logically be inferred from the information in the passage？

A．Non-economists tend to criticize the prevalence of market exchange in economists' models.

B．Non-economists tend to reject the distinction between zero-sum and positive- sum models made by economists.

C．Non-economists tend to disparage the lack of utopian thinking on the part of economists.

D．Non-economists tend to dismiss the economists' tendency to view human interactions as egotistic behavior.

E．Non-economists tend to interpret the lack of reliance on power models as evidence of economics' "dismal nature".
