问题 Most earthquakes occur within the upper 15 miles of the earth’s surface. But earthquakes can and do occur at all depths to about 460 miles. Their number 【C1】______as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as【C2】______as 100 in a month, but the yearly average does not vary much.
The【C3】______of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set, it will still stand no matter how【C4】______you shake the table. But if you build a toy house with a(n) 【C5】______of cards, a slight shake of the table will make it fall. An earthquake in Agadir, Morocco, was not strong enough to be recorded on distant instruments, but it completely destroyed the city. Many stronger earthquakes have done comparatively【C6】______damage. If a building is well constructed and built on solid ground, it will【C7】______an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building【C8】______. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.
The United Nations has played an important part in reducing the damage done by earthquakes. It has sent a team of experts to all countries known to be【C9】______by earthquakes. Working with local geologists and engineers, the experts have studied the nature of the ground and the type of most practical building code for the local area. If【C10】______, these suggestions will make disastrous earthquakes almost a thing of the past.
A. strongly B. sites C. high D. extent
E. pile F. violently G. followed H. decreases
I. effected J. resist K. pack L. affected
M. lessens N. subsist O. little [br] 【C1】
选项
答案 H
解析 decreases，上下文题及词义辨析题。根据词性，此处应当填入动词。根据下文“地底460英里处几年才发生一次地震，而接近地表处可能一个月就发生100次”，可见越深人地底，地震次数越少。可选范围为“decreases，lessens”，而lessen的意思是“减轻”，比如说“减轻痛苦，减轻疼痛，减轻影响”；decrease的意思是量上的减少，是客观的。故选decreases。
