An astronaut’s work may sound exciting, but living in space isn’t as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them.
When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts’ fingernails(手指甲) and even make them fall off.
In space, you don’t have many choices in what you eat. It’s hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs(碎屑). Crumbs could fly around everywhere.
In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting(噴水) gun and a washcloth.
Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they’re in space to try to keep their bones strong as long as possible.
Perhaps the hardest part of life in space is the feeling of loneliness. Astronauts sometimes have to spend weeks and even months away from Earth. They miss their friends and families.

"The word "sport" first meant something that people did in their free time. Later it often meant hunting wild animals and birds. About a hundred years ago the word was first used for organized games. This is the usual meaning of the word today. People spend a lot of time playing football, basketball, tennis and many other sports. Such people play because they leant to. A few people are paid for sport they play. These people are called professional sportsmen. They may be sportsmen for only a few years, but during that time the best ones can earn a lot of money. For example, a professional football player in England earns more than 300,000 dollars a year. The stars earn a lot more. International golf and tennis champions can make more than 500,000 dollars a year. Of course, only a few sportsmen can earn as much as that.
Perhaps the most surprising thing about sportsmen and money is that the stars can earn more money from advertising than from sports. An advertisement for sports equipment does not simply mean, "Buy our things". It says, "Buy the same shirt and shoes as…". Famous sportsmen can even advertise things like watches and food. They allow the companies to use their names or a photo of them and they are paid for this. Sport is no longer just something for people's spare time.

A．famous people spend too much money and time on sports

小題2:In this passage "professional sportsmen" means people " ".

A．who teach others how to make money in sports

A．what most of the people do in their spare time

B．hunting wild animals and birds in the forests

C．organized games

D．something that people are paid to

小題4:Which of the following is TRUE?

London used to be “foggy” for the same reason that cities like Beijing or Chongqing are “foggy” today．The “fog” was in fact smog, a mixture of smoke and fog．In other words, it was made by air pollution．In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter．By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air．A new law was made and nobody could burn coal in any British city．Within a few years, the air became much cleaner．There were no more “pea-soupers”．
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago．However, this problem is more difficult for Chinese cities to solve．One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses．If these factories were closed, this would harm the economy and lots of people would lose their jobs．Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive．
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution．As a result, there are fewer “pea-soupers”in Beijing than there used to be．

The World's Largest Insect
This giant insect can be used as a toy. A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.
African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.

A．the world's largest insect

B．a toy used in many parts of the world

English is very important in the modern world. Many people want to learn it well. Here are some things that I want to say about learning it.
To learn English well, you need two things－passion and good learning methods (方法). Passion is the more important one. Why? Because passion makes you want to learn English. Learning methods only tell you how to learn it better and faster.
If you love learning English, you will learn it regularly (有規律地) and spend much time on it. It will also be easy for you to remember new words and grammar rules. ________ For example, some people like history and know a lot about World War II. If you ask a person who doesn’t like history to memorize all the facts, he probably can’t do it.
When you don’t want to learn English, you can do the following things.
First, imagine that you can talk to native speakers just as you talk in your mother language. Imagine yourself to be a manager in a foreign company. Imagine you’re living in an English-speaking country.
Second, use English as much as possible. This is very important. The more you use English, the better you’ll learn it. English is very popular, so you can use it everywhere. You can watch American cartoons, write English diaries, and read interesting books written in English.

“Yes, ladies and gentlemen, welcome aboard NASA’s Space Elevator. We’re going to leave soon. The entire ride will take about five hours, so sit back and enjoy the trip. As we rise, be sure to look out the window. You’ll see the sky change from deep blue to black. It is one of the most wonderful views（景色）you will ever see! ”
Does this sound like the Sci-Fi Channel? Well, it’s not. Scientists are thinking that a “space elevator” will be possible toward the end of the 21st century. A space elevator will consist of a long cable (電纜) from the Earth’s surface into space to an altitude(高度) of about 35,786 km. “Elevators” will travel along the cable and move people and loads between Earth and space. One of the greatest advantages is that the cost will be much less. Researchers estimate (估計) that a passenger with baggage at 150 kg might cost only $222! Compare that to today’s cost of around $3.3 million for the same weight. It would make “cheap” space travel possible. Scientists believe carbon nanotubes (納米管) may be used to make high-strength materials for the cables, although they are still being studied.
It was Arthur C. Clarke who brought this idea to the general public. In his science fiction novel Fountains of Paradise, engineers build a space elevator on top of a mountain peak on an island. One day, Clarke was asked a question by a student during his speech. The student asked when the space elevator would become a reality. Clarke answered, “Probably about 50 years after everybody stops laughing.” He’s got a point. When we stop thinking of something as impossible, then we start working on its development.
小題1:Why should passengers in a space elevator look out the window while they are moving into space?

A．Because the blue sky is very beautiful.

B．Because the view outside is wonderful.

C．Because the sky changes from black to blue.

D．Because the trip will take about seven hours.

小題2:Which of the following is NOT true according to the passage?

A．Scientists haven’t used carbon nanotubes to make the cables.

B．Traveling in space elevators will cost much less in the future.

C．Passengers will be able to travel in space elevators with baggage.

D．Space elevators will travel for 35,786 km around the Earth’s surface.

小題3:What is the best title for this passage?

A．Possible Now: Space Travel	B．Cheap Space Travel
C．Going into Space in an Elevator	D．Space Travel — Impossible
