Question

Imagine a world where air pollution is no longer a problem. Clean air is all around us. People don’t have to worry about polluting the air every time they drive their cars. They no longer need to face the problem of not having enough fuel（燃料）either.

Although scientists have been trying for many years to develop a new kind of car that does not need gasoline (汽油), they have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity（电）. This is the famous “hybrid car”. This car gets its name from the fact that it has a gasoline engine (引擎) and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars.

Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future.

1. The underlined word “they” in Paragraph (段落) 2 means ______.

A. carsB. drivers

C. engines D. scientists

2.Hybrid cars ______.

A. increase air pollution B. run only on electricity

C. have no engines insideD. need less fuel than ordinary cars

3. The passage tells us that with the development of cars, we may ______.

A. like electric cars B. drive cars easily

C. live in the world with clean airD. understand how hybrid cars work

4.The best title for the passage would be ______.

A. The Car of the FutureB. The Meaning of Hybrid

C. The Use of Hybrid CarsD. The Invention of the Car

 

Answer 1

1.D

2.D

3.C

4.A

【解析】

试题分析：这篇文章主要讲了如果污染不再是一个问题，那么我们就不必担心燃料问题，科学家在研究一种不需要燃料的汽车但是都没有成功，现在科学家们发明了一种混合动力汽车不污染环境。

1.词义猜测题。根据短文Although scientists have been trying for many years to develop a new kind of car that does not need gasoline (汽油),科学家们一直在尝试研制一中不烧汽油的新型的汽车，但是他们都没有成功可知they指代的是科学家们，故选D。

2.细节理解题。根据短文第二段They also cost drivers less money because they need less fuel than ordinary cars.可知混合动力车比普通的车需要的燃料少。可知应选D。

3.主旨大意题。通读整篇文章可知汽车的发展可能会使我们居住在更清洁的环境。故选C。

4.标题归纳题。通读整篇文章 可知这篇文章最好的标题是“未来的汽车”故选A。

考点：科技类短文阅读。
