    情态动词强化训练答案解析

    1.【答案】C。

    【解析】祈使句也可附加疑问句。谓语形式通常用will, 如果前部分是let´s形式, 附加问句常用shall。

    2.【答案】D。

    【解析】had better后应接动词原形, B.必须,语气太强烈。sb. would rather do sth.某人宁愿做某事,与本句意思不连贯。might as well+动词原形,意为“最好还是……”。

    3.【答案】A。

    【解析】should后接动词完成时表示过去不该做的事情实际上已经做了,是虚拟语气用法。接动词原形表示现在与未来的情况,因此,A为正确答案。

    4.【答案】D。

    【解析】must在本句中表示推断，后接完成式, 表示对过去发生的事情进行猜测。这种用法仅限于肯定形式。如表示否定的猜测时, 则用can´t/could not表示对现在事情的否定猜测; 用have been doing 或can´t/couldn´t have been done表示对过去事情的否定猜测。因此, 答案为D。

    5.【答案】B。

    【解析】 “ must+have+ 过去分词”表示对过去发生的动作或存在的状态作可能性最大的推测，意为“必定，已经”。 can+have+ 过去分词，表示对过去发生的行为怀疑或不肯定。有本来可能做而没有做的意思，是虚拟语气用法。“ should+have+ 过去分词”表示过去应该做而实际上未来得及做的事，有本该的意思。

    6.【答案】D。

    【解析】选项 couldn´t have been 表示推测，符合句意。因此选D。

    7.【答案】B。

    【解析】A) shouldn´t do “不应该做…”；B) can´t have done “不可能做…”；C) can´t do “不会做，不能做…”；D) mustn´t have done 结构不常用。选项B合乎题意。

    8.【答案】C。

    【解析】“will+不定式进行体”表示将来时间。有两种用法：1)表示将来某一时间正在进行的动作。2)“单纯”表示将来要发生的动作。

    9.【答案】D。

    【解析】本题主要是A)和D）的辨析，be able to 与can的主要区别在于前者表示客观的能力，后者主观更多色彩更浓。本题根据时态及全句的内容，看出这是个客观的事实，因此应选D)。

    10.【答案】D
