问题     Nowadays groups of scientific workers, often supposed by their governments, spend their time studying  the occurrence of earthquakes. It is very likely that they will be able to【S1】______earthquakes or influence  the direction of their movements, which are determined by events far below the surface of the earth. But the facts they report and the theories suggested by those facts may enable scientists to【S2】______the centers of future earthquakes and even predict the time of their occurence. It is only when the【S3】______of events that we call an earthquake can be seen as a pattern that predictions can be made. Part of its pattern  is external and visible, or capable of being recorded by sensitive instruments above the earth’s surface.
    Scientists and engineers studied the shock waves of the San Francisco earthquake. Tile city was rebuilt  and new features were【S4】______to strengthen buildings and【S5】______a constant water supply in the event  of another earthquake. Large underground tanks were constructed to supply water if【S6】______supplies could not be tapped. Special【S7】______were taken to prevent fires, which often do more damage than earthquakes  themselves. The San Francisco earthquake【S8】______scientists with valuable information. Since the effects of the break were visible at the surface, scientists could【S9】______what actually happened, and reports of the incident were an important【S10】______to the world’s store of knowledge about earthquakes.

选项
答案 D
解析 这是一个以强调句型出现的复合句，被强调的部分为时间状语，其主语the______ of events后还跟着有that引导的定语从句。整句意思为只有在我们称作地震的事件______可以被看成是一种模式时才能作出预测。the sequence of events 意为“事件发牛的顺序”，符合题意。consequence 意为后果，与题意不符。
