A．must put B．should have put C．might put D．might have put 【答案】D 【解析】 【详解】 考查情态动词。句意：——我的词典在哪里？我记得昨天放在这里了。——你或许放错了地方。“might have +动词+ed形式”表示过去可能完成的动作。根据所提供的情景Where is my dictionary? I remember I put it here yesterday.可判断出把词典放在某个地方发生在过去，所以要用“might have +动词+ed形式”。“should have + 动词+ed形式”表示“(过去)本来应该做某事”。must意为“一定”，是肯定的推测，与所提供的情景的矛盾。might put表示现在发生的事。故选D。 2．-- Did Jim come? -- I don’t know. He _______ while I was out. A．might have come B．might come C．must have come D．should have come 【答案】A 【解析】 【详解】 考查情态动词推测用法。句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。根据前文I don’t know.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。对过去情况的推测为情态动词+have done，must have done 一定做了某事，should have done 应该来过，不符合，故选A。 【点睛】 情态动词+have+过去分词的用法，表示推测或判断过去的情况。 can/could+have+过去分词用法：①多用于否定句和疑问句中。表示对过去某事发生的可能性的否定或质疑，意为：不可能（已经）......了-（否定句）/可能（已经）......了嘛？-（疑问句）②用于肯定句中。表示对过去没有做某事的遗憾，含有轻微的责备，意为：本来可以......的（但实际上没有......）。You could have done better, but you were too careless.（肯定句。他能做得更好的） should/ought to+have+过去分词用法：用于肯定句中。表示对过去没有做某事的遗憾，含有责备的意思，意为：本来应该......的（但实际上没有......）。用于否定句中-表示对过去已经做了某事的责备，意为：本来不应该......的（但实际上已经......了）。He should have been asleep.（肯定句，他本应去睡觉的）He shouldn't have been asleep.（否定句，他本来不应该

A．might never happen B．could never have happened C．should not happen D．needn’t have happe ned 【答案】B 【解析】 【详解】 考查虚拟语气。句意：虽然这并不是这次旅行的目的，但我得到了一些新的领悟，那些领悟在我的日常生活中是本不可能发生的。此处考查虚拟语气，“我得到新的领悟”发生在过去，故此处是与过去事实相反，应用could/might/would/need/should+have done，“本不可能发生”是could never have happened，故选B项。 【点睛】 本题考查“情态动词+have done”的虚拟语气，其常用表达有： could have done本能做某事而未做couldn’t have done不可能做了某事 should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了 need have done本需要做某事而未做needn’t have done本不必要做某事而做了 2．Most of the top leaders expressed a common desire at the UN conference, ______ that different cultures ______ coexist with tolerance. A．the one ; must B．the one ; should C．one ; must D．one ; should 【答案】D 【解析】 【详解】 考查替代和情态动词。句意：大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。替代表泛指的单数名词，通常用one替代。此处用one替代前面的a desire，是同位语；结合句意第二空用情态动词should“应该”。故选D。【点睛】 that ,it ,one 代指前面的名词时的用法 1.one 指代前面出现的可数名词，是泛指。可以和冠词连用，也可以有自己的定语。一般不能用做特指，但和定冠词连用时可以是特指。如： Please show me the cup, the red one on the shelf. 2.It 指代前面提到的单数名词，相当于the one。当one是泛指的时候，指的是同名异物，it是指同一物体.如： ----Do you want the cup ? ---Yes ,I want it. 3.that通常用来代替前面出现的可数名词\不可数名词,主要是用来避免重复。如： The weather of Guangzhou is hotter than that of Beijing.
