Question

China_is_going_green. In order to reduce air pollution and oil­shortages, 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.

Answer 1

【小題1】B
【小題2】D
【小題3】C
【小題4】A

解析試題分析：本文敘述了為了減少空氣污染和石油­短缺,汽車制造商已經(jīng)宣布他們計劃開發(fā)混合動力汽車來進入中國市場，中國現(xiàn)在對環(huán)境問題非常重視，通過生產(chǎn)環(huán)保型汽車改善環(huán)境。
【小題1】主旨大意題。根據(jù)通讀全文可知，作者想要介紹一種新型環(huán)保的汽車。B
【小題2】句意理解題。通過閱讀第一段可以知道，中國現(xiàn)在對環(huán)境問題非常重視，通過生產(chǎn)環(huán)保型汽車改善環(huán)境。故選D。
【小題3】細(xì)節(jié)理解題。由第二、三、四段可得出答案。故選C。
【小題4】細(xì)節(jié)理解題。根據(jù)Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. 可知應(yīng)選A。
考點：環(huán)保類短文閱讀。
點評：要求考生從中選出最能概括文章主旨思想的一項作為正確答案。主旨大意題的干擾項（錯誤選項）有3種：
（1） 概括范圍太窄，只表達局部信息或某一細(xì)節(jié)，不能概括整篇文章的主旨大意。（2） 概括范圍太寬，所表達的內(nèi)容超出或多于文章闡述的內(nèi)容。（3） 無關(guān)信息：即文章中未提到、或找不到語言依據(jù)的信息。
