Passage Three
My husband and children feel very happy to live here. They can't see that we live on a dirty street in a dirty house among people who aren't good. They can't see that our neighbors have to make happiness out of all this dirt. I decided that my children must get out of this. The money that we've saved isn't nearly enough.
The McGaritys have money but they are so proud. They look down upon the poor The McGarity girl just yesterday stood out there in the street eating from a bag of candy while a ring of hungry children watched her. I saw those children looking at her and crying in their hearts; and when she couldn't eat any more she threw the rest down the sewer (下水道). Why? Is it only because they have money? There is more to happiness than money in the world, isn't there?
Miss Jackson who teaches at the Settlement House isn't rich, but she knows things. She understands people. Her eyes look straight into yours when she talks with you. She can read your mind. I'd like to see the children will be like Miss Jackson when they grow up.

第19题:
A
Why do plants grow in some places and not in others? Why does some land have so much growing on it,while other land has almost no plants growing on it at all?
To grow plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the earth only a few unusual plants can grow. That's why dry deserts everywhere are almost not covered by trees or grass.
Plants must also have a place in which to f,ut down their roots and grow. They find it diffi-culr to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones Io grow in.
Another thing plants must have before they can grow is food.
Whar will happen if we try to make things grow on the sandy beach? A few plants,such as beach grass,will grow in sand,L ut most plants won-t. Even if the weather is warm enough.and we water the plants each day. Many of them will die because the sand on this beach has al-most no food for plants.
( )21. According to the passage,plants need _________ things to grow well.
A. two
B. three
C. four
D. five
第20题:
B
Scientists are trying to make the deserts into good land again. They want to,bring water to the deserts. But more and more places of the earth is becoming deserts all the time, Scientists may not be able to change the deserts. Scientists think that people make deserts. People are do-ing 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 helpful to dry places. Plants don't let the wind blow the earth away. When 8 little bit of rain falls,the plants hold the water. Without plants,the land can become a desert much more easily.
( )26. Why can the land become a desert?
A. Because some places don't get very much rain.
B. Because plants don-t let the hot sun make the earth even drier.
C. Because people don't keep the earth well.
D. Because scientists haven-t learnt enough about the deserts.
