Question

After years of research and testing, the hybrid car was developed and put on the market. It’s an interesting and exciting new improvement in today’s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.

The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which are used to power a car’s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that’s not how it works. The 144 volt battery pack is actually recharged( 充电 ) through the energy that is produced when the car’s brakes are used. This is referred to as “regenerative braking”, because it generates electricity.

Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically ( 自动地；机械地 )shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

Have you ever ridden in a car with someone who ran out of gas? That probably wouldn’t happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

1.According to the passage, the word “hybrid” refers to ________.

A. a high tech discovery B. energy saving

C. a new invention D. a combination of two things

2.“Regenerative braking” is an important process of the hybrid car because ________.

A. it allows the car to come to a quick stop

B. it gives the driver a smoother ride

C. it produces energy to charge the battery

D. it can control the speed of the car

3.Which of the following is right about the EPA?

A. They designed hybrid cars.

B. They outlawed (宣布……为不合法) the burning of fossil fuels.

C. They set important guidelines that help control pollution.

D. Their main purpose is to protect endangered plants and animals.

4.Which of the following is the reason for developing hybrid cars?

A. They use less gas than regular cars.

B. They’re safer to drive than most cars.

C. They’re more modern than other cars.

D. They cost less than regular cars

【解析】

试题分析：本文介绍了已经上市的、更为节能环保的“混合动力汽车”。

1.D词义猜测题。根据文章第三段第一句话“A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered.”可知“hybrid”意为“混合，结合”，故该题正确答案为D.a combination of two things.

2.C细节信息题。根据文章第三段最后部分“The 144 volt battery pack is actually recharged( 充电 ) through the energy that is produced when the car’s brakes are used. This is referred to as “regenerative braking”, because it generates electricity.”可知，“Regenerative braking”之所以重要是因为它能产生电为汽车供能。故该题正确答案为C.it produces energy to charge the battery.

3.C细节信息题。根据文章第二段第三句“The EPA has set national standards to help control the level of harmful pollutants sent off into the air,”可知，环保局制定了控制污染的重要方针，故该题正确答案为C.

4.A推理判断题。根据文章第四段第一句“Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car.”可知，混合动力汽车比普通汽车更为省油节能，当然这也是发展研制这种汽车的原因。故该题正确答案为A.
