　　Earthquake
　　1．Every year earthquakes are responsible for a large number of deaths and a vest amount of destruction in various parts of the world．Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe．Some of the destruction is directly caused by the quakes itself．An example of this is the collapse of buildings as a result of the quake itself,0ther damages result from landslides or major fires which are initiated by the quake．
　　2．There are about a million quakes a year．Fortunately，however，not all of them are destructive．The intensity of an earthquake is measured on the Richter Scale，which goes from zero upward. The highest scale recorded to date is 8. 9. Major damage generally occurs from quakes ranging upwards from 6.0.
　　3. The actual cause of the quake itself is the breaking of rocks at or below the earth' s surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth's crust and continental drift.
　　4. In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Special instruments are used to help people record, for example, shaking of the earth. Scientists are trying to find methods that will enable them to indicate the exact time, location and size of an earthquake.
　　5. Certain phenomena have been observed which are believed to be signs of imminent earthquakes. These include strange behaviors of some animals, the changes in the content of mineral water, etc. The magnetic properties of rocks may also display special, pattern before major earthquakes happen.

　　地 震
　　地震每年都會(huì)在世界各地造成許多死亡和重大危害。大部分破壞性的地震都發(fā)生在環(huán)太平洋的狹窄地帶或者是從緬甸到歐洲的阿爾卑斯山沿線。一些破壞是直接由地震引起的。這其中的一個(gè)例子就是由地震所引起的建筑物的倒塌。其他的災(zāi)害起因于由地震所導(dǎo)致的滑坡或者大火。
　　一每年大約會(huì)發(fā)生l00萬(wàn)次地震。幸運(yùn)的是，不是所有的地震都具破壞性。地震的強(qiáng)度用里氏震級(jí)測(cè)定，從零級(jí)遞增。迄今有記錄的最高震級(jí)是8.9級(jí)。重大災(zāi)害一般是由6.0級(jí)以上的地震引起的。
　　地震真正的起因是由于地球表層或者表層以下巖層的斷裂所引起的�？茖W(xué)家們相信造成斷裂的壓力是由多種原因產(chǎn)生的。其中兩個(gè)主要原因就是地殼的膨脹和收縮以及大陸板塊的漂移。
　　為了減少損害，使人們免受地震之苦，科學(xué)家們正在尋求準(zhǔn)確的預(yù)報(bào)方法。科學(xué)家們借助一些特制的儀器來(lái)記錄地球的震動(dòng)，并正在努力尋求能夠預(yù)報(bào)確切時(shí)間、地點(diǎn)和震級(jí)的方法。
　　人們觀察到某些現(xiàn)象是地震即將到來(lái)的征兆。這包括一些動(dòng)物奇怪的行為，水里礦物質(zhì)成分的變化。在大地震到來(lái)之前，巖石磁性也會(huì)呈現(xiàn)出特殊的狀態(tài)。
