Question

Earthquakes may happen anywhere on the earth.When some plates of the earth move suddenly，an earthquake happens.Many earthquakes begin under the sea.They often happen near the mountains，too.

　　During an earthquake，the shakings make rocks rise suddenly and even crack(断裂) open.Houses fall，people are killed or hurt，and sometimes the whole villages or cities are destroyed.

　　Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and made maps that show the "earthquake belts".In areas in these belts，it's possible for earthquakes to happen.In these areas we should build strong houses to fight against earthquakes.

　　In the future，scientists will be able to tell when and where an earthquake will be before they happen.They can also tell people what to do and how to do it.

Answer 1

　　1.A 根据文章第一段中“When some plates of the earth move suddenly，an earthquake happens."可知，地球是由许多板块构成的，板块的移动产生了地震，所以根源在板块。

　　2.B 根据短文第一段内容可知，地震常发生在山脉附近。

　　3.C 根据短文第三段内容可知，地图将告诉我们地震带常发生地震。

　　4.B 根据短文最后一段内容可知，专家预测将来能判定地震发生的时间和地点，而不是现在。

　　5.A 根据短文最后一段内容可以推测出专家能预测地震发生的时间和地点，所以我们不必担心将来发生地震。
