Question

China is going green. In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽車) 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 off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (勻速行駛). A specially designed battery 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 traditional car. At this point, the car's gasoline engine is dormant (休眠). 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 onboard (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 charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, 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 their gasoline when driving a car

D. announce plans to develop hybrid vehicles for China

2.Which of the followings is NOT true?

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 onboard 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 percent of their power to run up hills.

D. They have smaller engines than traditional gasoline ones.

4.What can we conclude from the story?

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.

試題分析：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(diǎn)是不僅能用汽油發(fā)動機(jī)也可以充電,而且裝有特殊的引擎,當(dāng)上坡或者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(diǎn)進(jìn)行了詳細(xì)的介紹.

1.B推理判斷題。文章首段提出了一種綠色環(huán)保的車Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car,然后整篇文章對此車進(jìn)行介紹，由此可知文章的目的就是介紹這種新型車,答案選B.

2.C細(xì)節(jié)理解題。根據(jù)文章第四段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,C選項(xiàng)內(nèi)容錯誤.

3.A細(xì)節(jié)理解題 。本文介紹綠色環(huán)保汽車,所以環(huán)保應(yīng)該是最大的特點(diǎn),根據(jù)文章末段可知這種混合燃料汽車不僅可以使用汽油做動力,也可以用電,所以答案選A.

4.D細(xì)節(jié)理解題。根據(jù)文章末段When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries.可知D選項(xiàng)正確.

考點(diǎn)：考查社會科學(xué)類短文閱讀。
