A．might B．could C．should D．would 【答案】D 【详解】考查情态动词。句意：他过去常常花几个小时在图书馆里，仔细研读那些似乎没人记得的古代手稿。根据句中often及语境可知，此处描述的是过去习惯性的动作，would可用于表示过去经常性、习惯性的行为，符合题意；might表“可能”，could表“能够”或过去的可能性，should表“应该”，均与语境不符。故填D。 18．It was extremely frustrating because the new security system _________ recognise my fingerprints, no matter how many times I tried. A．wouldn’t B．needn’t C．mustn’t D．shouldn’t 【答案】A 【详解】考查情态动词词义辨析。句意：这非常令人沮丧，因为无论我试多少次，这个新的安全系统就是不识别我的指纹。A. wouldn’t（过去）总是不、就是不；B. needn’t不必（表没有必要）；C. mustn’t禁止（表强烈禁止）；D. shouldn’t不应该（表责任或建议）。根据“no matter how many times I tried”可知，此处强调反复尝试后的结果，“It was extremely frustrating”说明系统持续无法识别指纹，所以“wouldn’t”符合“系统始终不识别指纹”的语境。故选A项。 19．—Look! The light in the dormitory is still on. —Lucas ________ have forgotten to turn it off when he left as he was the last one to leave the dormitory. A．must B．would C．could D．should 【答案】A 【详解】考查情态动词。句意：——看！宿舍的灯还亮着。——Lucas一定是最后一个离开宿舍的，所以他离开的时候忘记关了。A. must have done一定做过某事；B. would have done本来会去做某事（却没做）；C. could have done本来能做某事（而未做）；D. should have done本来应该做某事（而未做）。根据“The light in the dormitory is still on.”和“when he left as he was the last one to leave the dormitory.”可知，灯还亮着以及Lucas是最后一个离开的情况，推测他一定是忘了关灯。故选A。 20．Mr. White ________ at 8:30 for the meeting, but he didn’t show up. A．had arrived B．should arrive C．should be arriving D．should have arrived 【答案】D 【详解】考查情态动词。句意：怀特先生本应在8:30到达会场，但他并未露面。根据but he didn’t show up可知，这里是说怀特先生本应做而实际上未做的事，用should have done，意为“本应该做……（而实际上没有）”。故选D。 21．—I saw Mr. Thompson at the airport this morning. —It ______ him. He’s on a business trip in New York until Friday. A．couldn’t be B．shouldn’t have been C．mustn’t be D．can’t have been 【答案】D 【详解】考查情态动词用法辨析。句意：——今天早上我在机场看到汤普森先生了。——不可能是他。他一直在纽约出差，要到周五才回来。A. couldn’t be不可能是（用于对现在情况的否定推测）；B. shouldn’t have been本不应该是（表虚拟，指过去本不该发生的事却发生了）；C. mustn’t be不应该（表不应该，不用于推测）；D. can’t have been不可能是（用于对过去情况的否定推测）。由语意可知，“看到汤普森先生”是早上发生的过去动作，且根据“他在纽约出差到周五”的事实，可判断过去看到的人“不可能是他”，需用对过去情况的否定推测。故选D项。 22．In his childhood, my grandfather ______ sit under the old apple tree for hours, listening to stories told by the village elders.

A．must B．should C．need D．can 【答案】D 【详解】考查情态动词辨析。句意：抑郁症是一种常常由生活中的激烈竞争和巨大压力导致的心理问题，如果治疗不当，它可能会成为一种具有破坏性的疾病。A. must必须，一定；B. should应该；C. need需要；D. can能，可能。根据“a mental problem that often results from fierce competition and great pressures in life”以及“if not treated properly”可知，抑郁症本身是一种心理问题，但在特定情况下（治疗不当）有成为具有破坏性疾病的可能性。can在这里表示理论上的可能性，符合语境。而must表示肯定的推测，语气过于绝对；should表示应该，不符合句意；need表示需要，也不符合语境。故选D项。 28．— That important document is nowhere to be seen. — Don’t worry.
