Cleaning up Our Environment
提纲
1．随处可见的环境污染。
2．怎样才能使环境清洁。
3．你的看法。
    The sky looks grey; the rivers become black; the grass is covered with plastic bags. You will easily get your hair and shoes dirty while walking along the streets, and the air smells terrible. That is our environment now. That is the world we live in. Wherever you are, whatever you do, you can hardly escape from pollution.
    But is there anything we common people carl do about it? Yes, there is much that we can do. We can throw rubbish not on the ground, but in garbage cans; we can help to publicize the importance of environment preservation; we can write letters to our friends on ordinary paper instead of sending cards, because 4,000 cards amount to one tree, and trees are important to better our environment. Moreover, we can encourage the government to punish the. act of pollution.
    When the sky is blue again, the rivers become clean, and the grass is always green, we will live a healthier and happier life.
