In most parts of the world, many students help their school make less pollution. They join in “environment(环境) clubs”. In an environment club, people work together to make our environment clean.
Here are the things students often do.
Turn off the water! Do you know that some toilets can waste(浪费) twenty to forty tons of water an hour?
In a year, that would fill a small river! In environment clubs, students mend those broken toilets.
No-car day. On a no-car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember:
Walk, jump, bike or run.
Use your legs! It’s lots of fun!
No-garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!

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. 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 and foods. 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.
