An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocentre, and the location directly above it on the surface of the earth is called the epicentre.#4.1.2 刷外刊 返回目录 8 Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!#4.1.3 刷外刊 返回目录 9 △ The earth has four major layers: the inner core, outer core, mantle and crust. The crust and the top of the mantle make up a thin skin on the surface of our planet. 刷外刊 返回目录 10 But this skin is not all in one piece—it is made up of many pieces like a puzzle covering the surface of the earth. Not only that, but these puzzle pieces keep slowly moving around, sliding past one another and bumping into each other. We call these puzzle pieces tectonic plates （构造板块）, and the edges of the plates are called the plate boundaries （板块边界）.The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake. 阅读理解·语篇导读 本文介绍了什么是地震、地球的结构和地震的成因。 刷外刊 返回目录 1. 信息匹配 According to the test, what do the numbers in the picture refer to?( ) a.the epicentre b.the fault plane c.the hypocentre B A.①-a, ②-b, ③-c B.①-b, ②-a, ③-c C.①-c, ②-a, ③-b D.①-b, ②-c, ③-a 【解析】推理判断题。根据第一段后两句可知，①为断层面（the fault plane）， ②为震中（the epicentre），③是震源（the hypocentre），故选B项。 刷外刊 返回目录 12 2.Which is the usual process of an earthquake?( ) B A.Small quakes→The large quake→No more quakes B.Small quakes→The large quake→Small quakes C.A volcanic eruption→The large quake→Small quakes D.Small quakes→Storms→The large quake 【解析】推理判断题。根据第二段内容可知，地震过程为：前震（小震）→主震 （大震）→余震（小震）。选项B符合此顺序。 刷外刊 返回目录 13 3.Which question can be put back on “△”?( ) A A.What causes earthquakes and where do they happen? B.How many layers does the earth have and what are they? C.What is the relationship between faults and plate boundaries? D.Can scientists predict when earthquakes will happen? 【解析】推理判断题。第三段与第四段主要介绍了地震成因与发生位置，故选A项。 刷外刊 返回目录 14 4. 文章出处 In which unit of an English textbook would this passage most likely appear?( ) A A.Natural Disasters and Earth Science. B.Travel Safety and First Aid Skills. C.Modern Technology in Geography. D.Environmental Protection Methods. 【解析】推理判断题。本文主要介绍了地震的相关内容，与自然灾害有关，故选A项。 刷外刊 返回目录 15 $
