Question

— Li Fan won the first prize in the national physics competition.
— I ________ he was the winner.

A．shouldn’t have thought	B．must have thought
C．need have thought	D．could never have thought

Answer 1

D

试题分析：考查情态动词用法。Shouldn’t have done本不应该做某事，实际上却做了；must have done一定做了某事；need have done本需要做某事；could not have done不可能做了某事；句意：—李凡在国家物理竞赛里获得了第一名。—我不可能想到他是胜利者。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。
