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(混合動力車輛)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(勻速行駛).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 (車載的)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 (油門)，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.

1.  The author writes this passage mainly to .

A.    teach people how to drive a hybrid car

B.    introduce a new kind of "green" car

C.    show how to save gasoline when driving a car

D. announce plans to develop hybrid vehicles for China

A.    The hybrid cars reduce air pollution and oil shortages.

B.    The car's gasoline engine doesn't work until it reaches about 24 km/h.

C.    This kind of car is completely controlled by an on-board computer.

D.    A specially designed battery motor provides extra power when needed.

3.    What is the most important feature of hybrid cars?

A.    They are powered by both a rechargeable battery and gasoline.

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】為了節(jié)能環(huán)保，汽車制造商宣布他們專門為中國市場研制了一種混合燃料汽車。這種汽車最大的特點是不僅能用汽油發(fā)動機也可以充電使用，而且裝有特殊的引擎，當上坡或需要加速時可以給予額外的動力。在本文中作者還對這種新型汽車的其他特點進行了詳細的介紹。

B寫作意圖題。文章首段提出了一種綠色環(huán)保的汽車，然后整篇文章對此車進行介紹，由此可知，文章的目的就是介紹這種新型車。故選B項。

C 細節(jié)理解題。根據(jù)文章第四段中的"…when you step on the gas pedal (油門)，you are actually telling the computer how fast you want to go."可知，這款車并非完全由電腦控制, 因此C項表述錯誤，故選C項。

A 細節(jié)理解題。本文介紹綠色環(huán)保汽車，所以環(huán)保應該是最大的特點。根據(jù)文章末段可知這種混合動力汽車不僅可以使用汽油做動力也可以用電，故A項正確。

D 細節(jié)理解題。根據(jù)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項正確。
