Trees are useful to man（人类）in three very important ways. The first important way is that they provide man with food, wood and other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It's not easy for man to live on the earth, either.
The second important way is that trees give us shade. On a hot summer day, people are eager(渴望)to have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and to animals.
The third important way is that trees help to prevent drought（干旱）and floods（洪水）. However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers. In the end he finds that he has lost the best friends he had.

　　No one knows how man learned to make words. Perhaps he began by making sounds like those made by animals. Perhaps he grunted(发出呼噜) like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him——water splashing(场所飞溅), bees humming(嗡嗡作响声), a stone falling to the ground. Somehow he learned to make words. As the centuries went by, he made more and more new words. This is what we mean by language.

　　People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. Each contains four or five hundred thousand words. But we do not need all these. Only a few thousand words are used in everyday life.

　　The words you know are called your vocabulary. You should try to make your vocabulary bigger. Read as many books as you can. There are plenty of books written in easy language. Your dictionary is your most useful book.
