Have you ever seen people building houses? To build a house , you need workers. They use their hands , tools(工具) and machines to put things together. Building the ISS（国际太空站） is the same. The difference is that the workers are astronauts. They walk in space and use robots’ arms and hands to do their work.
In the space station ,astronauts are comfortable. The temperature there is about 21℃.But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(阴暗处)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes----spacesuits.
Spacesuits also keep astronauts safe from flying rubbish(垃圾)in space.Each time people go into space , they leave rubbish there. So astronauts should be careful because there’s a lot of rubbish, some rubbish goes many times as fast as a plane !
Space walking is not easy , and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900man-hour of work.
【小题1】What’s the temperature in the space station?
A. 21℃            B120℃             C. -85℃               D.-21℃

Big ocean(海洋)fish have almost disappeared from the world since the start of business fishing in the 1950’s．The scientists found that the number of large fish has dropped by 90 percent in the past fifty years．The study took ten years．The researchers collected records from fishing business and governments around the world．The magazine Nature published the findings．
The scientists say the common way called longline fishing is especially harmful to large fish．This way includes many fishing lines that are connected to one boat．If these lines are joined together，they can reach one hundred kilometers．They hold thousands of sharp metal hooks to catch fish．Longline fishing is especially common in the Japanese fishing industry．Records show that Japanese boats used to catch about ten fish for every hundred hooks．The study says longline fishing boats now might catch one fish per hundred hooks．
The scientists say business fishing can destroy groups of fish much faster than in the past．The study suggests that large fish can disappear almost completely from new fishing areas within ten to fifteen years．Ocean life system could be destroyed．
It’s not the only worry that the number of large fish is becoming smaller and smaller．What’s worse．they are smaller in size than their ancestors(祖先)．

For several years, Americans have enjoyed teleshopping—watching TV and buying things by phone.Now teleshopping is starting in Europe (欧洲).In a number of European countries, people can turn on their TVs and shop for clothes, jewelry, food, toys, and many other things.
Teleshopping is becoming popular in Sweden, for example.The biggest Swedish company sells different kinds of things on TV in 15 European countries, and in one year it made ＄100 million.In France there are two teleshopping channels, and the French spend about ＄20 million a year to buy things through these channels.
In Germany, until last year teleshopping was only possible on one channel for 1 hour every day.Then the government allowed (允许) more telepshopping.Other channels can open for telebusiness, including (包括) the largest American teleshopping company and a 24?hour teleshopping company.German businessmen are hoping this new teleshopping will help them sell more things.
Some people like teleshopping because it allows them to do their shopping without leaving their homes.With all the problems of traffic in the cities, this is an important reason.But at the same time, other Europeans do not like this new way of shopping.They call teleshopping “junk (垃圾) on the air”.Many Europeans usually worry about the quality (质量) of the things for sale on TV.Good quality is important to them, and they believe they cannot be sure about the quality of the things on TV.
The need for high quality means that European teleshopping companies will have to be different from the American companies.They will have to be more careful about the quality of the things they sell.They will also have to work harder to sell things that the buyers cannot touch or see in person.
【小题1】Teleshopping is ____ in Europe.   

The earth is our home；we must take Care of it. This means keeping the land，air and water   clean.
Pollution is a dirty word. To pollute means to make things unfit(不合适的)or unclean to use. Pollution comes in many ways. We see it，smell it，taste it and drink it. Pollution is beginning to threaten(威胁)our health，or happiness and our life.
Man. has been polluting the earth from the time he first made fire，washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty. Men moved to another place. At first the problem was not so serious because there was plenty of clean air，land and water. There weren’t so many people then and their wants(需求)were fewer. All the dirty things could be absorbed(吸收)by nature and soon. covered over(恢复)， But this is no longer true. The increase of population(人口增长)and the development of industry have changed that. Man is slowly polluting. his environment.
Through the use of poison(农药)，mall has polluted land! killing the animal. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water，killing the fish.
Our increasing population is part of the problem. More people more waste.
Where is this all to end? Are we turning the world into a big rubbish dump，or is there any hope that we can get rid of(摆脱)the pollution ?Luckily，millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under
【小题1】Which sentence is WRONG?

All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain(食物链).Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears.
All life needs sunlight to live on. But only plants can use sunlight directly. Plants are“factories”.They make food from sunlight, water and things in the soil and air.
Plants feed all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.
What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. But men often break up the food chains. They kill wild animals. They also make rivers, lakes and seas dirty. When these rivers, lakes and seas are polluted, the fish in them cannot be eaten. If men eat the fish, they will get strange diseases.
Each form of life is linked to all others. Breaking the links puts all life in danger.

The first Earth Hour was held in 2007 in Sydney, Australia when 2.2 million individuals(个体) and more than two thousand businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had grown into a global event with more than 50 million people across 35 countries and territories（行政区）participating(参加). Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent(紧急) by the hour. In March 2009, millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries and territories have promised their official support for the event. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour. A record said 128 countries and territories joined the global display of climate action.
The event is organized by the World Wide Fund for Nature, also known as the WWF. The organizers say climate change is one of the greatest threats(威胁) facing wildlife and nature. They also say when it comes to save energy and money, big changes start with small steps like turning out the lights. Now people are all joining together in a global effort to show that it’s possible to work on global warming. Earth Hour has brought about some new changes to our lives. People join in activities such as candle-lit dinners and star-gazing parties as a response to the call for "going dark".

This year , Earth Hour is asking people to take the next step and go beyond one hour. So if you haven’t done so, next year, late half past eight to half past nine, let us turn off the lights for one hour for the environment! Earth Hour is a call to stand up, to take responsibility(责任) and to get involved(与……有关) in working towards a better future. Earth Hour is a message of hope and a message of action. Everyone can make a difference. 
【小题1】What’s the main idea of the passage?                              

What’s the red star in the sky through a telescope(望远镜)? It is Mars. Do you want to know more about it? Take the “Mars Orbit Express”!
“Mars Orbit Express” is a space probe (探测器). It was sent towards Mars by American scientists on August 12th，2005. Its tasks are to study Mars’ atmosphere and return photos to Earth. But before that “Mars Orbit Express” must travel about 100 hundred million kilometers and seven months. It reached Mars’ orbit(轨道)in March，2006.
Mars and Earth have similar weight and size. However，Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50℃. The temperature at noon only reaches 20℃ during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos.
Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives，Mars becomes bad. “Earth easily could have turned out like that.” said an scientist, “It is important for us to find out why and Mars Orbit Express’ should do that.” “Mars Orbit Express” also would help scientists to learn what might happen to Earth in the future.  “Mars Orbit Express” would work for about four years.
【小题1】 What can you see through a telescope when watching Mars? ________.
