如何保护我们的美丽世界
At first,we must make ourselves clean.For example,we must wash our clothes when they are dirty.We should not litter waste things about,and draw on the wall.We mustn't spit in public or cut down trees. We should plant more trees around our neighbourhood.We should pick the rubbish up and throw them into the dustbin when we see them. We must make our world more and more beautiful,don't you think so?
