问题 Canadian scientists have calculated that one human being should be struck every nine years by a meteorite, while each year sixteen buildings can be expected to sustain damage from such objects.

选项 A、one human being should be struck every nine years by a meteorite
B、a human being should be struck by a meteorite once in every nine years
C、a meteorite will strike one human being once in every nine years
D、every nine years a human being will be struck by a meteorite
E、every nine years a human being should be struck by a meteorite

答案 D

解析 首先,A、B、E中的should的使用不对,should作情态动词,含有“应该”之意,在本句中,该语气是不合逻辑的,而应当用will表示“将会”。C、D之间几乎是一致的,只不过时间状语一个在前,一个在后,从语意看无太大差异。但根据while的前后对比关系及前后尽可能形式一致原则,选D而去C,因为未划线的while从句中时间状语each year在句首。
