1．3 阅读讨论
When some plates of the earth move suddenly, an earthquake happens. Many earthquakes begin under the sea. In fact, earthquakes may happen near high mountains.
During an earthquake, the shakings make rocks rise suddenly and even crack open. Houses fall, people are killed or hurt, and sometimes the whole villages or cities are destroyed. Some villages even disappear completely.
Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and make maps that show the "earthquake belts". In areas in these belts, it is possible for earthquakes to happen. In these areas we can build strong houses to fight against earthquakes.
In the future, scientists will be able to predict exactly when and where an earthquake will happen. They can also tell people what to do and how to do it.
1．According to the passage, why does an earthquake happen?
An earthquake happens, because some parts of the earth move suddenly.
2．When do you want to build a house in an area in the "earthquake belt", What should you pay attention to?

a. If an earthquake happens, first I will keep calm. And then find a safe place and get there as quickly as possible.
b. If I were sleeping in my bedroom when the quake happened, I would get up quickly first, next I would wake up my family and my neighbours. Then we could run to a safe place. And finally we could escape being trapped or killed.
5．Do you think people can stop earthquakes?
At present, we still can not prevent the earthquake from happening. But now we know much more about earthquakes and the cause of earthquakes. For centuries, man has been making researches on earthquakes. For example, more than 2000 years ago, Zhang Heng, a Chinese scientist invented a machine to detect earthquakes and scientists today still use it to detect and measure the strength of earthquakes. With the development of science and technology, more useful machines will be invented, so we believe people can stop earthquakes one day.。
