Question

阅读理解 　　When some plates of the earth move suddenly, an earthquake happens．Many earthquakes begin under the sea．Earthquakes may happen anywhere on the earth．They often happen near the mountains． 　　During an earthquake, the shakings make rocks rise suddenly and even crack(断裂)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 make maps that show the “earthquake belts”．In areas(地区)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． (1) A large number of earthquakes often happens ________． [　　] A． in the area B． on land C． at night D． next to mountains (2) The reason for an earthquake is ________． [　　] A． the result of rock plate sudden movement B． that there are so many plates on the earth C． that the sea is too deep D． rocks’ cracking open (3) A map showing the earthquake belts will tell people ________． [　　] A． what kind of houses to build B． what kind of houses can stay up in an earthquake C． where earthquake may happen D． how to keep themselves safe during an earthquake (4) In the future we’ll be no longer so afraid of earthquakes ________． [　　] A． with the help of scientists’ exact prediction(预报) B． because of a map showing the “earthquake belts” C． because we can guess the date and place of earthquakes D． as scientists know what to do and how to do it (5) Choose the best title fro the passage． [　　] A． An Earthquake B． A Scientist and an Earthquake C． How to Fight Against Earthquake D． Earthquakes Today and Tomorrow

Answer 1

答案：1．D;2．B;3．C;4．A;5．A;
解析：

(1)	第一节最后的一句话是本题答案的出处．答案题时，尤其要注意该句中的often一词．
(2)	短文的“When some plates of the earth move suddenly, an earthquake happens”这一句明确告诉我们：地球板块突然移动时，就导致地震的发生．选项A 不是地震的成因，而是地震产生的结果．这从“…the shakings make rocks rise suddenly and even crack open”一句中可以看出．
(3)	地震带(earthquake belts)是可能发生地震的地方．这由第三段的中间几句所描述的内容可知．
(4)	将来科学家能预测出地震发生的时间和地点．有了这种精确的预报，人们当然不会再对地震那么恐惧了．
(5)	短文主要围绕地震的成因、危害以及对未来科学家们从事地震研究的展望，向我们介绍了地震方面的知识．故选项A为最佳答案． 　　地震是地球上对人类生存构成威胁的最严重的自然灾害之一．科学家们经过研究，发现了地震活动最频繁的地方．生活在地震带地方的人们可以采取适当的措施减少其危害．也许，将来科学家们能在地震之前预测出发生的地点和时间．
