     Trees are useful to man in three very important ways. The first important way is that they provide

man with food, wood and other products (产品). Trees provide not only man with food, but also many

animals with food. Without trees many animals can 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 (想象) how

important the shade of a tree is to man and to animals.

     The third important way is that trees help to prevent drought (旱灾) and floods. However, in many

parts of the world, man has not realized (意识到) 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.
