Earthquake

1.Every year earthquakes are responsible for a large number of deaths and a 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 extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results 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 0 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 earth-quakes.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.
选项 Scientists have been working hard to warn people__________.
A:by the quake itself
B:not be prevented
C:to cause damage of property and loss of lives
D:of a possible earthquake
E:the unusual behaviors of some animals
F: the strange behaviors of human beings
答案D
解析本题考查的是对所读材料大意与主旨的掌握。本段主要讲述的是关于地震的强度，从0开始，历史上记录的地震强度最大为8.9级，6级以上的地震常有较强的破坏性。
本题考查的是对所读材料大意与主旨的掌握。本段的主要内容是介绍地震发生的原因，地球表层或之下的岩体的断裂导致地震发生，更深层次的原因科学家认为主要有地壳缩胀和大陆漂移。
本题考查的是对所读材料大意与主旨的掌握。本段主要介绍为避免或减少损失，科学家努力通过一些仪器和方法尽可能准确地预测出地震发生的时间、地点和级别。
