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.

A.The Earth.         B.The Greek god.     C.Solar Impulse.      D.Birds.

3.In the passage, what is mentioned as the cause of pollution in China?

A.Overpopulation.                        B.Burning coal or gas.

C.Using solar energy.                      D.Heavy traffic.

4.What does the writer mean by “That’s a pretty long flight”?

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.

5.The passage is most probably taken from___________.

A.a Greek myth      B.a science fiction     C.a story-book       D.a science magazine

 

Winter is dangerous because it’s so difficult to know what is going to happen and accidents take place so easily. Fog can be waiting to meet you over the top of a hill. Ice might be hiding under the melting(融化)snow, waiting ahead to send you off the road. The car coming to you may suddenly slip across the road.

Rule Number One for driving on icy roads is to drive smoothly(平稳地). Sudden movements can make a car very difficult to control. So every time you either start or stop your car, increase or reduce your speed, you must be as gentle and slow as possible. Suppose you are driving with a full cup of hot coffee on the seat next to you. Drive so that you wouldn’t spill(溅) it.

Rule Number Two is to pay attention to what might happen. The more ice there is, the further down the road you have to look. Test how long it takes to gently stop your car. Remember that you may be driving more quickly than you think. Generally, allow twice of your usual stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times and you will not get into trouble.

1.The writer tries to       in this passage.

A.show his dislikes about bad winter weather

B.give information about winter weather

C.ask people not to drive in winter

D.advise people about safe driving in winter

2.According to the passage, the writer thinks that      .

A.people should not drive in the snow

B.drivers should think more about problems in winter driving

C.people drive too fast in winter

D.winter drivers should stop their cars less

3.In the passage the writer talks about a cup of coffee     .

A.to show how important smooth movements are

B.to ask the drivers to bring some soft drinks with them

C.to tell the drivers to be more relaxed

D.to show how it can be spilled

4.Which of the following is NOT TRUE?    

A.Traffic accidents take place easily in winter.

B.Fog and melting snow often cause car accidents.

C.The stopping distance on ice is as long as the usual one.

D.In winter you should drive your car with great care.

5.Which traffic sign shows the main idea of the passage?
