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.
【小题1】What does “chariot” really refer to in the last sentence of Paragraph 1?
A.The Earth. | B.The Greek god. | C.Solar Impulse. | D.Birds. |
A.It can only fly at night. | B.It has already flown across the US. |
C.It is powered by the sun. | D.It needs gas to work. |
A.Overpopulation. | B.Burning coal or gas. |
C.Using solar energy. | D.Heavy traffic. |
A.It takes a lot of time to get Solar Impulse going. |
B.Solar Impulse moves very slowly. |
C.Solar Impulse will be in use for a long time. |
D.Solar Impulse has a long way to go to take the place of the sun. |
A.a Greek myth | B.a science fiction | C.a story-book | D.a science magazine |

Throughout history, people have been interested in knowing how language first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the language of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original language of this family was spoken about 4,500 years ago. Many of the present-day languages of Europe and India are modern forms of the language of 4,500 years ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. In time, some even die out completely. About 1,000 years ago, English was a little known relative of German spoken on one of the borders of Europe.
If a language has a number of speakers, or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of people. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can’t understand speakers from other parts.
