三、阅读
（A） Pollution
Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest is pollution（污染）. Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog（烟雾）.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, they mustn’t blow dirty smoke into the air.
We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

In most parts of the world, many students help their schools make less pollution （污染）. They join “environment clubs（环境俱乐部）”. In an environment club, people work together to make our environment clean.
Here are some things students often do.
No-garbage（垃圾） lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
No-car day. On a no-car day, nobody comes to school in a car-not the students and not the teachers! Cars give pollution to our air, so remember:
Walk, jump, bike or run.
Use your legs! It’s lots of fun!
Turn off the water! Did you know that some toilets can waste（浪费）twenty to forty m3 of water an hour? In a year, that would fill a small river! In environment clubs, students mend those broken toilets.
We love our environment. Let’s work together to make it clean.

（C）
These two passages appeared in a newspaper. Both writers have their own ideas on zoos.
1. Zoos Do a Good Job
It is good to keep animals in zoos. I know a lot of people think it is wrong to keep animals in zoos. However, I believe that zoos have many good points.
Firstly, zoos are places for people to see many different kinds of animals from all over the world. Without zoos, most people would never see a real bear or tiger.
Secondly, zoos look after the animals very well. The animals are always given food and cleaned regularly（定期）. In the world, it is not always possible for an animals to find food, so sometimes it goes hungry. But animals kept in zoos never go hungry.
Thirdly, zoos protect the animals they look after. They offer them safe places to live in. In the wild, some kinds of animals are in danger of becoming extinct（灭绝）. But zoos give these animals a chance to live. Without zoos, there would be fewer kinds of animals in the world.
From Maria Smith
2. I disagree with Maria!
In Maria’s letter, she says that zoos are good for animals. I am afraid that zoos are not good for animals, they are only good for people.
It is unnatural（非自然的） and unfair to keep wild animals in cages （笼子）. Most animals are kept in cages that are too small for them. In the wild, these animals would travel freely. In zoos, they can’t do this. This is why the bears and tigers always look so sad.
Most cages are not very clean, either. It is true that zoos give the animals food regularly, but this is not natural. Wild animals are used to looking for their own food. We should treat（对待） animals in the same way that we treat other people --- with respect.
Would anyone be happy if you don’t let him go outside his home? Would Maria like to have lots of people standing outside her flat looking at her? No, she wouldn’t. And animals don’t like it, either.
From Philip Black
（ ） 1. Maria and Philip have quite different ideas on keeping animals in zoos.
（ ） 2. In Maria’s opinion（观点），a real bear or tiger can only be seen in zoos.
（ ） 3. Maria thinks that animals live better in zoos than in the wild.
（ ） 4. According to Philip, if cages are big and clean enough, tigers and bears will look happy.
（ ） 5. Maria and Philip both agree that zoos are good for people.
（ ） 6. In the two letters, they are discussing how to make animals in zoos happy.

（二）范文：
1. I think that we shouldn’t build zoos, so I agree with Disgusted. It isn’t fair to keep animals in the cages, because they’re supposed to have their own space. Animals Friend said that animals could live much longer in zoos. I disagree with him. Although they can be taken care of by people, they can’t run freely like the wild animals. Also, I believe that animals are unhappy in zoos. Well, some people said they slept all day, others said the wild often went hungry. I feel that the animals in zoos will become lazy. Therefore, I have to say I agree that people have to stop building zoos at the moment.
2. I think we can’t only use “Yes” or “ No” to decide that a thing is good or not. If animals are kept in zoos, they well sleep all day and become lazy. If we let them live in nature, they will run freely and I believe that they must be happy. But some endangered animals may become fewer and fewer. So you see, I agree with both them. I feel that we should keep animals in some large and natural places so that we can help them and the animals will be happy.
In a word, we all hope the animals can live in a suitable way, don’t we?
【励志故事】
攀山的启示
顺着山谷去爬一座白云缭绕的大山，没想到不少人还带着七八岁的孩子。登山，大人都爬着费劲，何况孩子。可是孩子们欢呼着，兴奋着，叽叽喳喳，总是走在大人的前面。山谷蔚秀，岚云清流，野花杂树，芳草萋萋，石阶深深，引得孩子们欢呼雀跃。到了山上，还要走十多里山路去一座寺庙，孩子们一听更是兴致勃勃，走在前面开路。
一天下来，走了四十里路，大人们个个累得腰酸腿疼、东倒西歪，孩子们却兴奋地仰着小脸问：“什么时候还来这里玩呢？”大人们纳闷：平常在城里走路，孩子们走几里就嚷着腿疼，爬山走这么远的路，孩子们怎么都不嚷累呢？
鸟语花香的美景，将孩子们引入幽境；目不暇接的新奇，让他们兴奋；柳暗花明的境遇，充满悬念和爽心。
看来，兴趣是生命飞翔的翅膀，它能将枯燥和沉闷转化为鲜活生动和美丽轻盈。培养你的生活情趣吧，它能激发你的潜能，开发你的智慧，磨炼你的意志，陶冶你的性情，使你克服重重困难，攀上成功的顶峰，永远保持着一颗年轻向上的心。
