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

D



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。

a.should have 本该看见的，却没有。
