him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most
important. Man wants to make money from trees, so he has cut them down in large numbers, only to find
that without them he has lost the best friends he had. And also, he is usually too careless to plant and look
after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are
trees, their roots break up soil (土壤)-make the rain in-and also bind (粘合) the soil, thus (这样) stopping it
from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away,
causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless
desert.
B. they give him cool
C. they give him wood and other things
D. they help him to stop drought and floods
B. new trees are not well looked after
C. man has not paid enough attention to planting trees
D. all the above
B. there are too many rainfalls
C. strong winds bring a lot of sand
D. there are no longer trees to keep the rain and protect the top-soil.
B. The Function of Tree Wood
C. How do People do with Trees
D. The Usage of Tree Roots

so people can live and grow food. They are learning a lot. about the deserts. But more and more of the earth
is becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert? Scientists think that people make deserts. People are doing
bad things to the earth.
Some places on the earth don"t get very much rain. But they still don"t become deserts. This is because
some green plants are growing there. Small green plants and grass are very important to dry places. Plants
don"t let the hot sun make the earth even drier. Plants don"t let the wind blow the dirt away. When a little bit
of rain falls, the plants hold the water. Without plants, the land can become a desert much more easily.
( )2. Land is becoming desert little by little.
( )3. Scientists can change desert back into good land easily.
( )4. Small green plants need a lot of water.
( )5. Plants can keep dry land from becoming desert.
