The world’s population will jump from 6.8 billion to 9 billion by 2050. The need for cars will jump with it. But the oil(石油) won’t keep up with the number of cars on the road. So the price of oil will go up.
Electric cars aren’t perfect just yet. It can take eight hours to charge(充电) a car for only 100 miles of driving. And the distance(路程) that cars can go depends on driving conditions(条件). How far it travels depends on the weather and traffic.
Price is a problem, too. Electric models cost much more than oil-powered cars. The good news is that electric-car technology is getting better. As it does, the prices of this kind of cars are dropping.
To charge the car, the US Department of Energy is paying for at least 10,000 charging stations around the country. Private businesses are also getting ready for it. It will cost about $3 for each charge.
Carmakers are coming up with other ways to make the car cleaner and cheaper. Cars may run on clean diesel(柴油). So who knows what will power the car you may be driving in 10 years? The chances are that it will be something that’s clean and easy.

解析
试题分析:本文介绍的是电动小汽车,由于汽车的使用量越来越大,石油越用越少,油价越来越高,所以产生了环保的电动小汽车,它主要的动力来源是电。
小题1:细节理解题。根据原文These quiet, clean cars run on electricity.可知电动汽车是安静,干净的。故选C。
小题2:细节理解题。通过阅读可知,由于汽车越来越多,石油越来越少,油价会越来越高,从而需要一种替代品,即电动小汽车。所以本段主要告诉我们电动小汽车出现的原因。故选A。
小题3:细节理解题。根据原文How far it travels depends on the weather and traffic.可知能行驶多远主要依靠天气和交通情况,故选B。
小题4:细节理解题。根据原文Price is a problem, too. Electric models cost much more than oil-powered cars.可知电动小汽车的弊端是电比油的花费还贵。故选C。

Tiangong-1 is China’s first space module(舱). It was sent into space in 2011. It will be developed into a large space station around 2020. A space station is a lab for scientific studies.Shenzhou X performed its first docking(对接)with Tiangong-1 on June 13. It docked twice during the 15 days.
