    Scientists are trying to make the deserts(沙漠) into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the desert. 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 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.
（   ）1. Deserts ______________.
       A. get very little rain                                                       
       B. never have any plants or animals in them

（   ）2. Small green plants are very important to dry places because ______.
       A. they don’t let the sun make the earth even drier

       D. A, B and C
（   ）3. Land is becoming desert little by little because ______________.
       A. plants can’t grow there                                 B. there’s not enough rain
       C. people are doing bad things to the earth.          D. scientists know little about desert
（   ）4. Which is the main idea of the first paragraph?
       A. Scientists know how to change land into good land.
       B. Land is becoming desert faster than scientists can change it back into good land.
       C. If scientists can bring water to the desert, people can live there.
       D. More and more places are becoming deserts all the time.
（   ）5. After reading this, we learn that ______________.

       B. it is good to get rid of (清除) the grass in the desert
       C. all places without much rain will become deserts
       D. it is good to grow crops on dry land

     Years ago, many zoos kept all kinds of animals in small cages (笼子). Small cages made it easy for people to see the animals, but a small cage is not a good place for an animal to live in.
Today zoos keep animals in different kinds of cages. The cages are very big and open. They usually have plants and a little lake. The cages look like the animals’ habitats (栖息地).
Zoos help to protect animals in the wild. How do they do this? Zoos teach people how animals live in the wild. Zoos want people to help protect the animals’ wild habitats.
Many plants and animals are going extinct. Mammoths, which are related (有关联的) with Asia elephants, are now extinct. There are no mammoths in the world today. Scientists say that seventy—four different kinds of living things go extinct every day!
Zoos are working together to stop animals from going extinct.

     A. are trying to keep all kinds of animals                B. are trying to free the animals
     C. teach people more about animals                        D. want people to feed the animals

Dear Editor
I am writing to you to tell you about my problems with my family. I am very unhappy now and I need help.
I think my parents don’t understand me. They don’t care what I like doing, but always talk about how I should study. They don’t let me go out with my friends at weekends. They always ask and even order me to stay at home and study. I’m sure I could still study very well even if I had more time to play, but they just don’t listen to me. We often argue with（与...争论）each other.
I really hope that my parents can become my friends. What shall I do? How can I let them know this? Please give me some advice. Thank you!
Yours
Mary
