OG-134

134. 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.

(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

这道题目做了两次，错了两次。每次都选了E。OG的解释是，"Choices A, B, and E can be faulted for using should in place of will to indicate future occurrences: should carries the suggestion, especially unwarranted in this context, that the Canadian scientists are describing what ought to happen."

但是我觉得作者的确是在做一种推测。按照他的计算方法，这件事情"应该"发生，而不是一定会发生。大家能否指点一下我哪里想错了?

为什么og说“The phrase once in every nine years is needlessly wordy in B and C”

我觉得加上once更能明确表达每九年才会有一个人被砸到一次，从而加深了“一年内16座building”比较
