Question

China is going green. In order to reduce air pollu?tion and oil shortages automobile manufacturers have announced their plans to develop hybrid vehicles(混合动力车辆)for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.

Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run on a recharge?able battery and gasoline. Hybrid cars have special engines which are smaller than traditional gasoline engines. They run at 99 per cent of their power when the car is cruising(匀速行驶).A specially designed bat?tery motor provides extra power for running up hills or when extra acceleration is needed.

Step into a Prius and turn on the engine. The first thing you notice is how much quieter it is than a tradi?tional car. At this point the car's gasoline engine is dormant(休目民).The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed you are effectively driving an electric car with no gasoline being used and no waste gas gives off.

The on-board (车载的)computer makes the decision about when to use a gas engine when to go electric and when to use a combination of the two. If you go over 24 km/h when you step on the gas pedal (油门)，you are actually telling the computer how fast you want to go.

The electronic motor recharges automatically using a set of batteries. When driving at high speed the gasoline engine not only powers the car but also char?ges the batteries. Any time you use the brake the elec?tric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a conse-qiience the car's batteries will last for around 200 000 miles.

B.    They are much quieter than traditional cars.

C.    They only use 99 per cent of their power to run up hills.

D.    They have smaller engines than traditional gasoline ones.

4.    What can we conclude from the passage?

A.    The batteries can be recharged at any time you want.

B.    Using the brake suggests that the gasoline engine should work.

C.    The batteries will last for 200 000 miles without being recharged.

D.    The gasoline engine charges the batteries as well as powers the car.

Answer 1

【文章大意】为了节能环保，汽车制造商宣布他们专门为中国市场研制了一种混合燃料汽车。这种汽车最大的特点是不仅能用汽油发动机也可以充电使用，而且装有特殊的引擎，当上坡或需要加速时可以给予额外的动力。在本文中作者还对这种新型汽车的其他特点进行了详细的介绍。

B写作意图题。文章首段提出了一种绿色环保的汽车，然后整篇文章对此车进行介绍，由此可知，文章的目的就是介绍这种新型车。故选B项。

C 细节理解题。根据文章第四段中的"…when you step on the gas pedal (油门)，you are actually telling the computer how fast you want to go."可知，这款车并非完全由电脑控制 因此C项表述错误，故选C项。

A 细节理解题。本文介绍绿色环保汽车，所以环保应该是最大的特点。根据文章末段可知这种混合动力汽车不仅可以使用汽油做动力也可以用电，故A项正确。

D 细节理解题。根据文章末段的"When driving at high speed the gasoline engine not only powers the car but also charges the batteries."可知D项正确。
