We _______the letter yesterday, but it didn”t arrive.

A．must receive	B．ought to receive
C．must have received	D．ought to have received

答案

D

解析

试题分析：考查情态动词用法。本句中的关键词在于yesterday,说明本句是对过去情况的虚拟或者推测，都要使用“情态动词+have done”；排除AB；must have done一定做了某事，是对过去发生的事情的肯定推测；ought to have done本应该做某事实际上却未做；句意：我们昨天本可以收到那封信的，但是我们却没有收到。故D正确。
点评：本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done 本应该做而实际未做。can’t have done 过去不可能做了某事；shouldn’t have done 本不应该做而实际做了。 need have done 本有必要做某事；needn’t have done 本没有必要做某事；注意没有 mustn’t have done的形式。
