　　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(斷裂) 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.

　　答案：

　　1.A 根據(jù)文章第一段中“When some plates of the earth move suddenly，an earthquake happens."可知，地球是由許多板塊構(gòu)成的，板塊的移動(dòng)產(chǎn)生了地震，所以根源在板塊。

　　2.B 根據(jù)短文第一段內(nèi)容可知，地震常發(fā)生在山脈附近。

　　3.C 根據(jù)短文第三段內(nèi)容可知，地圖將告訴我們地震帶常發(fā)生地震。

　　4.B 根據(jù)短文最后一段內(nèi)容可知，專家預(yù)測(cè)將來(lái)能判定地震發(fā)生的時(shí)間和地點(diǎn)，而不是現(xiàn)在。

　　5.A 根據(jù)短文最后一段內(nèi)容可以推測(cè)出專家能預(yù)測(cè)地震發(fā)生的時(shí)間和地點(diǎn)，所以我們不必?fù)?dān)心將來(lái)發(fā)生地震。
