Question

【题目】---Do you know how this disabled man succeeded in running such a big company?

--- I don’t know , but I think he __________ many difficulties.

A. could have gone through B. must have gone through

C. might go through D. need go through

Answer 1

【答案】B

【解析】

试题分析：句意：你知道这个残疾人是如何成功地经营这么大的一家公司吗？我不知道，但是我想他肯定经历过许多困难。could have done sth.本可以做某事；可能已经做了某事 must have done sth. 一定做过某事. 分析语境可知 go through difficulty 发生在过去，语境表示对过去情况的一种肯定的猜测，故用must have done结构。故选B。
