SECTION B PASSAGES

Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.

听力原文： Are electric cars the way of the future？ Automobile manufactures are under pressure to develop ca rs that do not pollute. One powerful motive is a California law requiring that by the year 2000 ten percent of new car sells in the state be so called zero-emission vehicles. These cars must put no pollutants whatsoever into the atmosphere.

California is a huge market for the automobile companies, so they are working hard to meet these standards. So far the electric car seems to be the best alternative. So the big advantage of electric cars is that they don't pollute. However they will be in competition with gas-powered cars and that's where the weaknesses come out.

The big problem is that the batteries that power electric cars weigh a lot relative to the amount of power they deliver. For instance, in one prototype electric car, the batteries weighed 400 kilograms. And they provide enough energy to go 250 kilometers before recharging, which takes eight hours. Compare that to a moderately fuel-efficient conventional car, it can go 600 to 700 kilometers on a tank of gas and refilling takes just minutes. If there are other drains on an electric car's batteries besides the motor, headlights, air conditioning or a heater, its already limited range will be significantly reduced. So automobile engineers are trying to make more powerful batteries that would increase the cars' range and make them more attractive to buyers.

What is the talk' mainly about？

A．Automobile safety.

B．Increasing fuel efficiency.

C．California's pollution laws.

D．Electric-powered cars.

It is difficult to imagine what life would be like without memory. (78) The meanings of thousands of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.

Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involving any change in the way an animal typically behaves. (79) Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat.

Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 "words"--ready for instant use. An average U. S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight.

The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person's memory is in terms of words and combinations of words.

According to the passage, memory is considered to be ______.

A．the basis for decision making and problem solving

B．an ability to store experiences for future use

C．an intelligence typically possessed by human beings

D．the data mainly consisting of words and combinations of words

SECTION B PASSAGES

Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.

听力原文： Some people argue that the pressure on international sportsmen and sportswomen kills the essence of sport-the pursuit of personal excellence. Children kick a football around for fun. When they get older and play for local school teams, they become competitive but they still enjoy playing. The individual representing his country cannot afford to think about enjoying himself, he has to think only about winning. He is responsible for an entire nation's hopes, dreams and reputation.

A good example is the football World Cup. Football is the world's most important sport. Winning the World Cup is perhaps the summit of international sporting success. Mention "Argentina" to someone and the chances are that he'll think of football.

In a sense, winning the World Cup "put Argentina on the map".

Sports fans and supporters get quite irrational about the World Cup. People in England felt that their country was somehow important after they won in 1966. Last year thousands of Scots sold their cars, and even their houses, and spent all their money traveling to Argentina, where the finals were played.

So, am I arguing that international competition kills the idea of sport？ Certainly not! Does the Argentina really believe that because eleven of their men proved the most skillful at football, their nation is in every way better than all others？ Not really. But it's nice to know that you won and that in one way at least your country is the best.

What is the author's main purpose in the passage？

A．To prove that football is the world' s most important sport.

B．To show that Argentina is better than others.

C．To compare Scotland with Argentina.

D．To explain the role of sport.
