There is no question that fewer teenagers are on the roads in the US.

In 1978, 50% of 16-year-olds had got their first driving licences. In 2008, according to the US Transportation Department, it was just 30%. The number of those aged 19 and under with driving licences has also been declining since 1978, when 11,989,000 had licences. In 2010, it was 9, 932,441, or 4.1% of American drivers.

In the UK, 683,273 teenagers have driving licences—just 1.85% of total licence holders, according to Department of Transport figures from September 2010.

But the decline in the US may have more to do with tougher tests and the introduction of the new rule in many states, which force drivers aged under 16 to be with licensed drivers of 21 years and older when driving.

In recent years, the annual number of journeys being made by American drivers of all ages has declined clearly for the first time ever. Car use began falling in 2007, when average petrol prices almost doubled to $ 4.12 a gallon, and the economy became worse.

But there are signs that it is getting back to normal and America remains a country on wheels. It has a higher number of cars per head of population than any other country in the world.

“Cars will always be a popular means of transportation in America. You have to take into consideration some places don’t have access to public transportation. Cars are the only way some people can get around,” says Kristin Nevels. This makes driving necessary in some rural states, where about twice as many teenagers are on the road than in big cities.

1.The underlined word “declining” in the second paragraph most probably means “　　 ”.

A. rising　　 B. dropping

C. improving　　 D. holding

2.In recent years cars are used less than before mainly because of 　　　　 .

A. traffic jams　　 B. harder tests

C. expensive petrol　　 D. worst economy

3.We can learn from the last paragraph that Kristin Nevels 　　　　 .

A. doubts the popularity of the car use in the future

B. thinks American people cannot live without Cars

C. holds a confident attitude to the cars’ future in America

D. believes America should build up its public transportation

4.What can be inferred from the text?

A. The UK has more teenager drivers than the US.

B. A 15-year-old boy cannot drive alone in the US.

C. The US has very developed bus transportation systems.

D. Big cities have more teenager drivers than rural areas in the US.

The earth is the only planet that scientists think has life. Why does the earth have life while the other planets (行星) don't? For one thing, the earth is just the right temperature. As the_third_planet from the sun, the earth seems to be just the right distance away. The planets which are closer to the sun are hot that their surfaces bake (烘烤) in the sun. The farthest planets are cold balls.

When the earth developed — which scientists believe may have happened about 4 billion years ago — many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.

Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special space suit, you could walk around on Mars. You would have to bring your own air to breathe, the air on Mars is too thin to breathe.

Mars has the largest volcano (火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected (未预测到的) sight on Mars is dried up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.

1.Which of the following is NOT the reason that the earth has life?

A. The earth is just the right temperature.

B. The volcanos on earth are lower than those on Mars.

C. There is oxygen in the atmosphere of the earth.

D. The earth seems to be just the right distance away from the sun.

2.The underlined phrase “the third planet” in the first paragraph refers to ________.

A. the Sun　　　　　　　　　     B. the Moon

C. the Earth　　　　　　　　     D. the Mars

3.Which of the following about the Mars is NOT true?

A. There could have been living things on Mars.

B. Mars has the largest volcano in the solar system.

C. There is almost no oxygen in the air on Mars.

D. Mars is smaller than the earth, and it is quite a bit cooler.

As you may expect, life in space is much different from life on earth. So of course people need some time to get used to it. How do they live, work and play up there?

Space food keeps getting more like the food we eat at home on the earth. In the past, astronauts could eat only freeze-dried food. But now the space station has water, microwave ovens and fridges. So astronauts can eat more usual kinds of food, like fruit, vegetables and ice cream!

All people in the ISS（国际空间站）have their own rooms. There’s no gravity, so they have to attach themselves to their beds, or they’ll float away! That may seem like a hard way to sleep, but astronauts say that sleeping in space is actually not too bad.

This is more important in space than on Earth. There’s not much gravity in space. Astronauts don’t stand up, sit down or walk in space, so their muscles don’t have to work much. They exercise on bikes and other machines for about two hours every day while they’re in space. In this way, they can still keep strong and healthy when they get back home.

Easy things like brushing your teeth can be hard in space with low gravity. Water doesn’t flow out of a tap, it floats in a bubble（水泡）! Astronauts used a special hose（软管）to take showers. And when they’re finished, they use a vacuum（真空的）hose to suck the dirty water off of their bodies. How do you go to the toilet in space? They use a special “air toilet”. It uses air, not water, to take everything away.

What do astronauts do when they aren’t working? They read books, play cards, listen to music or send e-mail to their friends and family. Sometimes they just sit and look out the window. Doesn’t sound like much fun? But what if you could see planet Earth out of your window, with a sunset or sunrise every 45 minutes?

1． Which of the following can be the title of this passage?

A. Life In Space.        B. Space Food. C. Showers In Space.        D. A Visit To Space

2．From this passage we know that _______.

A. astronauts eat quite different food in space from what they eat on the earth

B. astronauts ate only fruit in space in the past

C. astronauts can only eat freeze-dried food now

D. astronauts can only eat fruit and vegetables now

3．Astronauts attach themselves to bed so as to ________.

A. keep themselves warm                                             B. prevent themselves from floating away

C. have a good sleep                                                       D. feel better

4．Astronauts have to do exercise for two hours every day because ________.

A. they have nothing to do in space                  B. they are told to do so

C. they do so to keep healthy                              D. they do so to prevent them from sleeping

5．From the last paragraph we can guess that ________.

A. the sun moves fast around the earth

B. the earth circles round the sun very fast

C. the earth is very small

D. the spaceship circles round the earth once every 90 imnutes
