2021年12月英语四级阅读考试训练232021年6月英语四级考试答案科普：自然资 295词Every year, earthquakes are responsible for a large number of deaths and vast 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 e_tends from Burma to the Alps in Europe.Some of the destruction is directly caused by the quake itself.An e_le of this is the collapse of buildings as a result of vibration.Other damage results from landslides, tsunamis (large ocean waves) or major fires which are initiated by the quake.采集者退散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 0 upward.The highest magnitude recorded to date is 8.9.Major damage generally occurs from quake ranging upwards from 6.0.E_ceptions to this are those whose epicenters are located far from the inhabited areas. The actual cause of the quake itself is the breaking apart of rocks at or below the earths surface.This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the e_pansion and contraction of the earths crust and continental drift. In order to minimize the damage and lessen some of the suffering results from earthquakes, scientists are working on ways to enable accurate prediction.Two of the instruments presently in use to achieve this goal are seismograghs and tiltmeters.The former records any shaking of the earth: by means of calculations seismologist can accurately indicate the e_act time, location and size of an earthquake.The latter, as the name suggests, is used to record any changes in the title of the land. 1.Which of the following is the best title for this passage?A.EarthquakesB.The Cause of EarthquakesC.Earthquakes and Their DamagesD.How to Predict Earthquakes2.What kind of damages may not be resulted from an earthquake?A.The collapse of buildingsB.A large number of deaths. C.Vast amount of destructionD.Landslides, tsunamis and major fires3.In the last sentence of Para.2, the word “this” refer to _. A.the highest magnitudeB.major damageC.dateD.the previous earthquake4.According to the passage, the sequence before an earthquake is _. A.the breaking apart of rocks the production of pressure the e_pansion and contraction of the earths crust and continental drift and the quake itself. B.the e_pansion and contraction of the earths crust and continental drift the breaking apart of rocks the production of pressure and the quake itself. C.the e_pansion and contraction of the earths crust and continental drift the production of pressure the breaking apart of rocks and the quake itself. D.the production of pressure the breaking apart of rocks the e_pansion and contraction of the earths crust and continental drift and the quake itself. 5 What is the use of seismographs and tiltmeters?A.To record signals of earthquake. B.To prevent major earthquakesC.To predict when, where and how an earthquake happens. D.To lessen the suffering results of an earthquake.第 5 页 共 5 页
