Question

【题目】What a pity! Considering his ability and experience， he better.

need have done B.must have done C.can have done D.might have done

Answer 1

【答案】D

【解析】 句意为：太遗憾了！鉴于他的能力和经验，他本可能做得更好。need have done本来有必要做（而没做）；must have done是对过去发生的事情的肯定的推测，表示“过去一定做了”；can have done是对过去发生的事情的不肯定的推测；might have done表示“本来可以”。
