    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.

    2. Trees only provide man with food, don’t they?

    阅读并按要求做题。

    　　Trees are useful to men in three important ways：　　1　　, they give them shade, and they help to prevent drought and floods(防止洪水与干旱)．

    　　Unfortunately, in many parts of the world, men have not realized(意识)that the third of these is the most important．In their eagerness(渴望)to make money from trees, 　　2　　, only to find that without them they have lost the best friends they had．And also 　　3　　, so many trees are slowly gone．

    　　This doesn’t not only mean that men will have fewer trees．The results(结果)are even more serious：　　4　　, their roots(树跟)break up soil——having the rain go in——and also bind(固定)the soil(土壤), thus stopping it from being washed away easily; 　　5　　, the rain falls on hard ground and runs away, causing floods and carrying away the rich top-soil．

    A．some people have cut trees down in large numbers

    B．but where there are no trees

    C．they provide(供给)them with wood

    D．they are usually too careless to plant and look after new trees

    E．for where there are trees

    6．Which is the best title of the passage?________

    A．Planting More Trees

    B．The Problems of Trees

    C．Never Cut Down Trees

    D．The importance of Trees
