People all over the world are looking for ways to save energy and natural sources to protect our environment. Here’s an example of saving water.
A doctor called Jack Todd is very interested in cleaning water as well as saving money, so he has tried many ways, and in the end he developed a small and affordable system to clean waste water—the Living Machine. The machine can clean waste water in our homes or in our business.
The machine can clean waste water. First the waste water goes into a big plastic tank. In the tank, the wastes start to break down. Second, a few days later, the water is brought into a greenhouse full of plants and fish. With the help of sunlight, plants and animals, many chemicals can be removed from the water. That makes the water cleaner. Then the water can be used for washing or bathing. Though it can’t be used for drinking or cooking, the water is clean enough to water the flowers, wash the dogs and bathe.
This technology is good for the environment. It can also help to save fresh water and it can help provide the unpolluted water. If we take actions to do something to save energy on the earth, our planet will have a longer life and our life will be better.

Many people know that rubbish is a big problem on planet Earth. What many people don’t know is that junk（垃圾）has become a problem in outer space too.
According to BBC News, there are more than 22,000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes（望远镜）. There are also millions of smaller pieces of junk that we can’t see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth’s atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth’ s atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.
“The problem is becoming more challenging because we’re sending more objects into space to help people use their mobile phones and computers,” says Marco Castronuovo, an Italian space researcher.
“The time to act is now. The longer we leave the problem, the bigger it will become,” he says.
根据材料内容选择最佳答案。
11.What does the underlined word “these” in Paragraph 2 refer to
A. Telescopes. B. Satellites.
C. Pieces of space junk D. BBC news reports
12.Why is space junk considered a problem
A. It burns up after it re-enters the atmosphere.
B. It often stops the view of telescopes on Earth.
C. It could force new space tools to travel at slower speeds.
D. It may crash into other space tools causing damage or death.
13.Countries want future space tools to be able to fall back into the earth’s atmosphere so that ______.
A. the tools can be reused later
B. the tools don’t become space junk
C. the earth’s atmosphere can stay clean
D. the effects of space flight can be studied
14.How do the Germans plan to deal with space junk
A. Catch it with nets. B. Use robots to collect it.
C. Burn it in the earth’s atmosphere. D. Send it further away from the earth
15.In which section of the newspaper would you probably read this article

D
The trees have been on the earth for millions of years. But today trees are in great danger.
16 In the 1970s, many elm trees（榆树）in Europe were killed by Dutch elm disease.
17 This new danger attacks all the forests and woods of Europe from northern Sweden to southern Italy. First the branches turn yellow and brown. Then the trees’ leaves fall. The roots and trunk shrink（萎缩）. Finally the trees die. In the Black Forest in southern Germany, 75% of the trees have been destroyed or killed.
18 Nobody knows exactly, but it is probably air pollution or acid rain（酸雨）. Factories, power stations and cars give off tons of smoke with acid into the air. Sunlight turns these into poisonous substances（有毒物质）which fall with rain or snow onto the trees.
What can be done about acid rain 19
Acid rain doesn’t always fall on the countries which produce the pollution. The wind carries the poisonous substances from one country to another. Badly, the governments don’t want to spend money on them if the poisonous substances won’t harm the trees in their own countries.
20 The rainforests of Asia and South America are being cut down for firewood and building material. Something must be done. If the trees die, we will, too.
根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺、内容完整。
A. Trees are also threatened（威胁）by people.
B. What is killing the trees
C. Disease threatens trees.
D. Why don’t the governments do something to save the trees
E. Now an even greater danger is threatening trees.

We are studying in our beautiful school. It’s our duty to keep our school yard clean and tidy. It’s not good to spit in public places, such as the libraries, the classrooms and computer rooms. We should neither draw pictures on the walls nor throw any litter on the ground. We must do the cleaning every day in and out of the classrooms. Every one of us should have a good habit of keeping healthy. If everyone tries his or her best to do something useful for our school, I’m sure our school will become more and more beautiful.
