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 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（阴凉处）. On a hot summer day, people are looking forward to having 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（旱灾）and floods（水灾）. However, in many parts of the world, man has not realized（意识到）the third important way. They cut trees down in large numbers. There will be fewer trees in the future. People should protect trees, or they will lose their best friends. 1. Who do trees provide food for? _______________________________________ 2.
