  Why do earthquakes happen? Scientists explain that the outside of the earth
is made of a number of different plates(极块). For example, at San Francisco the
Pacific Plate which is moving towards the northwest meets the North American
Plate. The Pacific Plate is moving very   slowly-at 5. 3 centimetres a year.
Sometimes these two plates stop and do not move for years. Then suddenly, they
jump and an earthquake is felt. As the movement of these plates,West America
near the sea has always been a bad place for earthquakes. When the 1906
earthquake happened, the Pacific Plate jumped 5-6 metres to the north.
  We cannot stop earthquakes, but we can do things to make sure they don't
destroy(毁坏) the whole of cities. First,it is not a good idea to build houses
along the lines, where two of the earth's plates join together.Second, if you think
there may be an earthquake, it is better to build houses on rock not on sand.
Third, you must make the houses as strong as possible. Weak buildings will fall
down in an earthquake,but strong ones may stay up.

Can plant eat people? Probably not. But there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat- eating plant is the Venus flytrap(捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of the book.. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(苍蝇) touches one of the hairs, the leaf closes very quickly. Then the fly can’t go out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things, especially nitrogen(氮). Animal meat has a lot of nitrogen. So some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea.
根据短文内容判断。
1. The Venus flytrap grows in wet parts of the United States.
2. The Venus flytrap is a kind of plant.
3. The underlined word “presses” probably means(挤、压) in Chinese.
4. In the world, many animals eat plants but plants never eat animals.
