A report sho ( http: / / www.21cnjy.com )wed that environmental problems kill 3 million children under five years old each year, making them one of the key contributors in more than 10 million child deaths worldwise each year.Dangerous factors include indoor and outdoor air pollution, water pollution, lack of good hygiene facilities and poor ecological systems,it said.Another study showed that parents and experts from seven countries including the United States, India and Nigeria, regarded pollution as the biggest threat to children's natural living environment.

Some non-government ( http: / / www.21cnjy.com )al organizations and child centers also teach kids to protect the environment.“More parents have become aware of it. Family is now playing a more important role,”says a Chinese official.
Vera Lehmann, an ( http: / / www.21cnjy.com )expert from Germany says many Chinese are increasingly aware of polluted.“I was surprised to find how much schools in China are willing to contribute to educating the children on environment,” Lehmann said.“There has been a big change between now and ten years ago when I first traveled here.”

Water is very important to us. We can’t live without it.
There is a lot of w ( http: / / www.21cnjy.com )ater on the earth, but we can’t use most of it. About 97.4% of the earth’s water is salty. Most of the fresh water is snow and ice near the North and South poles.
We can use only abou ( http: / / www.21cnjy.com )t 1% of the water on the earth. We use water from both lakes and rivers. Some of the water evaporates(蒸发) and then becomes rain. Of course we use rain water for farms and other things. We use this water again and again.
Sometimes the earth’s ( http: / / www.21cnjy.com )water is in the wrong place. There is a lot of rain in the tropics(热带地区), but it is difficult to have farms in the tropics. Most of the land there is not very rich. Some desert land is rich, but there is only a little water in the desert.
Water is a problem for many people in the world.
( ) 6. How much of the earth’s water is not salty
A. 1% . B. 2.5%. C. 2.6%. D. 97.4%.
( ) 7. A lot of ra ( http: / / www.21cnjy.com )in in the tropics is in the wrong place because ________.
A. some of the ( http: / / www.21cnjy.com )land there is desert B. it is not easy to have farms there
C. the water ( http: / / www.21cnjy.com ) is very hot D. the rain water evaporates fast
( ) 8. Most of the land in the tropics is ________.
A. dry B. desert C. rich D. poor

C. we sh ( http: / / www.21cnjy.com )ould save water D. water is everywhere in the world
C
The world is not hung ( http: / / www.21cnjy.com )ry , but it is thirsty . It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of (短缺) water. Why Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly (直接地) . Man can only drink and use the 3% - the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted (污染) .
Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if (即使) every large city reused its water, still there would not be enough. What could people turn to next
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.
( ) 11 . The world i ( http: / / www.21cnjy.com )s thirsty because
A. 3/4 of the earth is covered with water
B. we have enough sea water to use directly
C. we haven't used all the water in rivers and lakes
D. about 97% of water on the earth can't be drunk or used for watering plants directly
( ) 12. Which of the ( http: / / www.21cnjy.com ) following is true
A. 3% of water on the earth is in rivers and lakes.
B. 75% of water on the earth is the sea.
C. 97% of the earth is covered with water.
D. 3% of water on the earth is sea water.
( ) 13. From the passage we know that
A. if every city reuses its water, we'll be in no danger of drying up
B. man can only drink and use about 25% of water on the earth
C. today in most large cities water is used only once
D. water can be used only once
( ) 14 . whi ( http: / / www.21cnjy.com )ch of the following is the most important to avoid water shortage
A. Save water and try to make good use of the water in rivers and lakes.
B. Don't pollute water and keep all rivers and lakes clean.
C. Make dirty water clean and then reuse it.
D. Try to find a cheaper way to get the salt out of the sea water.
( ) 15. What i ( http: / / www.21cnjy.com )s the best title of the passage
A. The Sea Water B. How to Save Water
C. The Thirsty World D. The Polluted Water
D
Napoga is a 12-year-o ( http: / / www.21cnjy.com )ld girl in Ghana, Africa. It is hard for her family to get clean water. Every morning, she leaves home at half past five to get clean water for her family in a village far away. It takes her six hours to get enough clean water for daily cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga. They can’t get enough clean water to keep healthy.
Earth Day is April ( http: / / www.21cnjy.com )22. But on all other days, we must also remember it. The water we use is the most important natural resource on Earth. Water covers 70% of the Earth’s surface (表面). But most of that is sea water. We can’t use it for many things. Fresh water covers only 1% of the Earth5 s surface.
You probably feel ( http: / / www.21cnjy.com ) lucky that your life isn’t as hard as Napoga’s. But that doesn’t mean you don ’ t have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes, and seas dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish too. Now, 34% of all kinds of fishes are dying out. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save more water for ourselves and our children.
( ) 16. Why does the writer tell the story of Napoga
