AVERAGE RESOURCES(资源)
620 m3 water	If we put flesh water and sea water together，we can each have 620 m3 water．But remember，sea water is too salty for us to drink if the factories don’t process(加工)it first．So，620 m3 is little．Saving water in daily use is important．
0．5 hectares of forests	There are 3．869 billion hectares(公顷)of forests on Earth．But we are losing them mainly because we cut trees too much．If we calculate(计算)at the size of a football field，we are losing 343，000 football fields every day，or 1，431 per hour，or 24 per minute !
1．5 centimeters long corals(珊瑚)	All the corals that we have now spread(绵延)for about 100，000 km in 109 countries．But each of us can only have such a little piece，because seas are get-ring polluted and corals are dying．
33 stars	According to the latest report，there are 200 billion stars in the Milky Way．Each of us can have 33 of them．Unfortunately，we cannot see most of the 200 billion stars from Earth．We can only see about 6．000 stars．If we don’t use telescopes(望远镜)or we have bad weather，we can only see about 2，000 stars．
90kg rice	On average(平均)，we get 0．54 billion tons of rice each year round the world and each of us can have 90 kg．Asia produces and eats 90％of all the rice．How long will it take you to eat up this 90 kg rice?

 “Haibao，the mascot(吉祥物)of the 2010 Shanghai World Expo，is very cute，”said Gu Hui，a school kid．“I want a big toy like the mascot．”

    Haibao looks like the Chinese word ren，which means people or a person．The name，a typical lucky one in Chinese tradition comes from the Chinese phrase “Si Hai Zhi Bao” —the treasure of the four seas．It also means the treasure of Shanghai，which lies beside the sea．

    Haibao’s blue curly(卷曲的)hair looks like the waves of the sea．Its smile is a sign of the healthy spirit of China．Those thumbs-up(翘拇指)will welcome millions of people to Shanghai from around the world．Its big feet show China has the ability to host a successful Expo．

    Haibao was created by two artists，one from the mainland(大陆) and the other from Taiwan．The design is about people living together in the city．The designers want it to fit the theme of the Shanghai Expo，that is，a good life should be created by all the people and people should have harmonious relationships(和谐关系) with nature and society，so that life in cities would be better．

    Surely the mascot will become the lucky symbol and cultural remark of Shanghai Expo．

Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.

  Beginning in the middle of the 20^th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.

  By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.

  So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.

  By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.

  So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.

April 22 is Earth Day. Everyone on Earth should care about and protect the earth!
The earth has warmed by about 1°F (华氏度) over the past 100 years, but why and how?
Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which makes the earth warmer.
First, greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.
When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one metre by 2100.
People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.
【小题1】Earth Day is probably set for people to ______.

A．learn more about the earth	B．make full use of the earth
C．take better care of the earth.	D．study the warmth of the earth

【小题2】We can infer (推断) from the passage that the reasons for the warmer earth are
______ now.

A．not very clear

B．completely secret

C．well known

D．not given yet

【小题3】Greenhouse effect comes from______.

A．sea rising

B．climate change

C．nature's unbalance

D．people's activity

【小题4】The passage mainly tells us that ______.

A．there is more rain now	B．we should protect the earth
C．we must stop pollution	D．sea level is getting higher

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 create a food chain (链条). 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 (链接) 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 (土壤) 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 humans? We are members of many food chains. We eat rice, vegetables, and fruits and so on. We also eat meat and drink milk. But we often break up the food chains. We kill wild animals and also make rivers, lakes and seas polluted. When these rivers, lakes and seas are polluted, the fish in them can not be eaten. If we eat the fish, we will get strange illnesses.
Each form of life is linked (关联的) to all others. Breaking the links puts all life in danger.
【小题1】Which living things can use the sun’s energy directly?

A．Animals.	B．Plants.
C．Animals and plants.	D．All living things.

【小题2】Who often destroy the food chains?

A．Humans.	B．Animals.
C．Plants and animals.	D．Humans and wild animals.

【小题3】Which of the following would be the best title for this passage?

A．The Sun’s Energy	B．Plants
C．Food Chains	D．Living Things
