Today I am at home. I talked about plants with my family. I know why plants are so important for us.
There are many plants around us. And we can't live without plants. Do you know why? Let me tell you. Plants help clean the air and it is pleasant to walk among the trees.

For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower.

Only if we human beings take some drastic measures can wild animals be preserved. 保护野生动物 许多野生动物正面临绝种的危险,因为它们生活的环境发生了极大的变化。
Plants seem to know which way is up and which way is down; besides, they seem to know right from left. If a cutting from a tree is kept alive, new shoots will grow from the endthat grew in the highest part of the tree.There is no noticeable difference between the top and the bottom of the living stick, even under a microscope. Even so, the stick will not send out shoots from the end it regards asbottom even if this end happens to be on top!Scientists studying this subject further split their cuttings in the direction of length.To their surprise, they made another new discovery. A good many more buds grew on the righthand side of the split surface than on the left. They split the sticks again and found that the buds again grew on the right side.The results of the entire study showed a 60% choice for the right side, proving that growing plants are mostly "righthanded.”
