题目内容
Thousands of years ago, people didn’t know that the Earth moved. They thought the sun really did move across the sky. The Greek god Helios was said to drive the sun around the sky with his chariot(战车). But now, these ideas have all changed. Nowadays, it is the sun that drives our “chariot” around the sky.
So what does all this mean? Well, quite simply, there is now a plane (or “chariot”) that is powered by the sun. It has special parts in its wings. These parts absorb power from the sun. They absorb so much power that they can carry on flying at night. In the Greek myths(希腊神话), Helios had to take a break at night. It seems we’re finally even more efficient than the gods themselves.
This plane is called Solar Impulse (“太阳驱动”号). It will fly across the US in May. This is very important for the future of the world.
So why is solar energy so good for us? Well, other kinds of energy cause a few problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy. The heat and chemicals(化学制品)from this make things work. But if we use the heat from the sun, we don’t have to burn anything, and there’s no pollution.
Solar energy is not all there yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. Solar Impulse could keep flying forever. Well, actually, the sun will run out too, one day, but not for another 5 billion years. That’s a pretty long flight.

试题分析:这篇短文主要谈到了利用太阳能作为能源的问题。
小题1:根据短文二三段Well, quite simply, there is now a plane (or “chariot”) that is powered by the sun. It has special parts in its wings. These parts absorb power from the sun. ……This plane is called Solar Impulse (“太阳驱动”号).描述,可知选C.
小题2:根据there is now a plane (or “chariot”) that is powered by the sun.描述,可知选C。
小题3:根据If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy.描述,可知选B。
小题4:根据but not for another 5 billion years.描述,可知太阳驱动可以利用很长的时间,故选C。
小题5:这篇短文主要谈论的是利用太阳能的问题,故最有可能出自一本科学杂志。选D。D
