Why do plants grow in some places but not in others? Why does some land have so many plants 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 there are almost no trees or grass in dry deserts.
Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built(被建立) on hard land. The plants there have only the soil between the cracks of the stones to grow in.
Another thing plants must have before they can grow is food. What will happen if we try to make things grow on the sandy beach? A few plants, such as grass, will grow in sand, but 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 almost no food for plants.
1.According to the passage, plants need_____ things to grow well.
A. two B. three C .four D. five
2.The underlined word“cracks”means“______”
A．long narrow opening
B. the surface of something
C. small plants on something
D. the bottom of something
3.From the passage, we can know it is____ for plants to grow in dry places.
A. easy B. difficult
C. impossible D. important
4.The passage can most probably be found in a ____ book.
A. science B. history C. travel D. math

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移)is probably the migration of the fish, which is called "salmon". This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall Into the sea.
