听力原文:A heater is using convection when it warms the air in a room. And the air in turn

warms the people and objects in the room. A hot water radiator, a stove and forced air furnace are all convection heaters. A quartz heater, on the other hand, heats the objects and people in a room without heating the air. It does this by producing radiation heat that travels like light waves. The radiation is then directed at objects by means of a reflector.

How is the quartz heater different from other types of heaters?

A.It heats only the objects in a room.

B.It is lighter in weight.

C.It heats the room quicker.

D.It is more common.

听力原文: Are electric cars the way of the future?Automobile manufactures are under pressure to develop cars that do not pollute.One powerful motive is a California law requiring that by the year 2020 ten percent of new car sells in the state be so called zero-emission vehicles.These cars must put no pollutants whatsoever into the at-mosphere.

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.

Why does the electric car seem to be the best alternative so far?

A.It is comfortable.

B.It is best made.

C.It causes no pollution.

D.It makes less noise.

听力原文:Are electric cars the wave of the future? Automobile manufactures are under press

听力原文: Are electric cars the wave of the future? Automobile manufactures are under pressure to develop cars that do not pollute. One powerful motive is a California law requiring that by the year 2000, 10% of new car sales in the state be so-called "zero emission vehicles". These cars must put no pollution, whatsoever, in the atmosphere.

California is a huge market for the automobile companies. So they are working hard to meet the standards. So far, the electric car seems to be the best alternative. So the big advantage of the electric cars is that they don't pollute. However, there will be a 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 weigh 400 kilograms and they provide enough energy to go 250 kilometers before recharging, which takes 8 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 the electric cars' batteries besides the motor, headlights, air-conditioning or heater, its already limited range would 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.

(33)

A.Automobile safety.

B.Increasing fuel efficiency.

C.California's pollution laws.

D.Electric-powered cars.

A scientist helped to wire the school, He says, "Here is a plan to connect 12 thousand California schools to the Internet."

Wiring schools in California can cost a lot of money. It needs to be done by volunteer effort or schools will not be able to afford it. They think that it will cost as much as fifty billion dollars.

Some people say that the money should be spent on teachers instead of computers. Some people say that it would be worth it to wire all of classrooms.

(33)

B.A student in London.

C.Home page on the Internet.
