Trees are useful to man in three important ways.
The first important way is that they provide(提供) man with food, wood and the 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(阴凉). On a hot summer day, people are eager(渴望) to have a rest under the tree after they have a long walk. You can imagine how important the shade of a tree is to man and animals.
The third important way is that trees help to prevent droughts and floods(防止干旱和洪水). However, in many parts of the world, man hasn’t realized the third way. They were cutting trees down in large numbers. In the end they find that they have lost the best friends they had.
根据短文内容，回答下列问题。
31． How many important ways are trees useful to man?
____________________________________________
32． Trees only provide man with food, don’t they?

C
When we feel the ground moves suddenly, it means that an earthquake may come. Many of the earthquakes first come under the sea and then happen anywhere on the earth. Especially they often happen near the mountains and seas such as Wenchuan, Japan and Indonesia.
When an earthquake happens, it’s very easy to cause a tsunami (海啸). Houses fall down, many people are injured and even died.
Now scientists are trying their best to study earthquakes. They make maps to show the“earthquake belts (地震带)”. So the houses there must be quite strong.
We believe that scientists will be able to tell us when and where an earthquake will happen in the near future. Also, they can tell us what to do and how to do. People can even use earthquakes to do something for us humans.
根据短文内容，判断正（T）误（F）。
36．Japan is a country with many earthquakes because it is near the sea.
37．In areas in the “earthquake belts”, people build strong houses for safety.

范文：Many students like getting on-line very much. They can learn how to use the modern machine — computers. They can learn much more knowledge from the Internet. It can make them clever by playing different kinds of games.
But some students spend too much time playing games. Some even make friends on-line. It takes them too much time to write too many letters to each other, so they do worse in their lessons.
I think they mustn’t get on-line when they’re studying at school. They can do it in summer or winter holidays.
