put专题九情态动词和虚拟语气五年真题精华考点一:情态动词的基本用法1.D本题考查情态动词的用法。题干的意思是:“我从未玩得更开心过这是完美的一天。”shouldnt have done表示“本不应该做而事实上已经做了”;neednt have done表示“本没有必要做而事实上已经做了”;wouldnt have done用于虚拟语气;couldnt have done表示“不可能做过”。此处用not和比较级连用表达最高级的含义,意为“从未比这更高兴过”。所以正确选项应是D项。2.C考查情态动词。句意:无论她怎么努力去推,这扇门就是打不开。情态动词will表示事物的倾向和特性,意为“总是,会”。从句中用的是一般过去时,因此此处应用will的过去式would。3.D考查情态动词。句意:这个周六你打算做什么?我不确定,但是我或许会去滚石演唱会。由答语中的“Im not sure”可知,答话人对自己的安排还不能确定,因此用might,表示“可能,或许”。must表示肯定的推测,意为“必须,一定”;would表示意愿;should表示“应该”。4.B考查情态动词。句意:当我还是个孩子的时候,我什么时候想看电视就可以看。根据题干中的whenever I wanted to可知,应填“能够”意义的词,并且是过去时,故选B项。5.A考查情态动词。句意:谁也没他慷慨;他有一颗金子般的心。could可能;must必须;dare胆敢,敢于;need需要。根据句意可知应选A项。6.B考查情态动词的用法。句意:既然Suzie不和我们一起吃晚饭,所以我们就不需要买这么多食物。may not不可以,neednt不需要,cant不可能, mustnt绝不可能,B项符合句意。7.C考查情态动词的用法。句意:根据学校规定学生在校时都必须要穿校服。shall用于第二、三人称陈述句,表示说话人给对方命令、警告、允诺或威胁。8.B考查情态动词的用法。句意:我靠他们足够地近以听见他们说汉语,而且我会像在中国可能做的那样说“你好”。must“必须”,should“应该”,表示义务或责任;can表示能力,均不合句意。might表示“可能”,符合语境。9.A考查情态动词的用法。句意:我要和John一起去欧洲度假,如果我能找到钱。此处考查了can的本意“能”,表示做某事的“能力”。其他选项不合句意。10.D考查情态动词的用法。句意:我没有必要用闹钟唤醒我,因为每天早上6点火车都会经过我的房子。neednt+动词原形表示“没有必要做某事”,符合句意。11.C考查情态动词的用法。句意:几天后,我哥哥打电话说他一切很好,但不愿意说他在哪儿。mustnt意为“禁止”;shouldnt意为“不应该”;wouldnt意为“不愿意”;mightnt意为“或许不”。12.A考查情态动词的用法。句意:警方依然没有找到失踪的孩子,但他们现在正在做他们所能做的一切。can可以,能够;may可能,许可;must必须;should应该。根据句意,选A。13.C考查情态动词的用法。句意:如果你非得要走的话,至少也要等到这暴风雨过去后。can可以,能够;may 可能,许可;must(表示主张)一定要,坚持要;will将要,愿意。根据后半句的劝告,选C。考点二:情态动词表推测1.B考查情态动词。句意:由于没有人帮他,他一定是独自做的那项研究。由句意可知,此处是对过去事情的肯定推测,因此用“must+have done”结构。can have done用于否定句或疑问句中,表示对过去情况的推测;would have done表示对过去将来情况的推测;need have done表示“本需要做某事却没做”。2.A考查情态动词。句意:孩子们一定是在树林里迷路了;否则,他们会按照计划到达湖边的营地了。根据句意可知,孩子们现在还没有到达,此处表示对过去事情的一种肯定推测,故用“must have done”形式。3.B考查情态动词。句意:不可能是词汇量导致你难以完成那道练习题,因为你掌握了大量的词汇。根据原因状语从句because you know a lot of words可知,主句应该是否定的,排除A、C。neednt表示“不必”,不符合题意,此处表示对可能性的推测,故选B,couldnt 表示“不可能”。4.A上句句意:“你不必带伞。不会下雨的。”而“我”认为下不下雨还拿不准。表示不太肯定的推测,用might。选A项。5.D考查情态动词。根据空后面的last night可知,Harry喝酒一事是过去的事情,结合语境可知此处表示对过去的事情的肯定推测,应该用must have done结构。6.A考查情态动词。句意:你的眼睛为什么这么红?你昨晚肯定没有睡好。是的,我熬夜写了一篇报告。cant have

wasnt certain说明他可能不来,也可能来,因此此处使用不完全否定might not,表示可能性极小的推测。选D。9.D考查情态动词表推测的用法。句意:你的新保姆怎么样?找不到更好的了。我们的孩子都很喜欢她。should应该;might可能,可以;mustnt禁止;couldnt不可能。表示一种否定的推测,语气不是很肯定。10.B考查情态动词表推测的用法。句意:早上好,我和人事部的Smith小姐有约。啊呀,早上好。那您一定是Peters女士。根据句意可知说话人对所判断的情况很肯定,故选B项。11.D考查情态动词表推测的用法。句意:杰克把他的父亲描述为一个意志坚强的人,他的父亲多年前肯定很勇敢。must have been表示对过去事情的肯定推测,符合句意。12.A考查情态动词表推测的用法。句意:恐怕Mr.Harding现在不可能来看你。他很忙。结合语境,根据情态动词用于疑问或否定推测时要用cant可知答案。13.C考查情态动词表推测用法。句意:“你一定打错了电话,”她说,“这儿没这个人”。对现在事实进行把握性极大的肯定推测用must,故选C项。14.C考查情态动词表推测的用法。句意:嗨,汤姆,你知道简在哪吗?她一定在教室,我刚才还看见她在那儿。根据语境可知,本题是对现在事实进行肯定推测,要用must be。考点三: 虚拟语气1.B本题考查虚拟语气。题干的意思是:“眼科医生建议孩子第一次视力检查应该在六个月大的时候进行。”remend建议,后接宾语从句时,从句用虚拟语气,谓语动词用should do形式,should可以省略,所以正确选项为B项。2.A考查虚拟语气。句意:我的母亲建议我们这个周末出去吃饭,换换口味。suggest作“建议”讲时,其后面的宾语从句要用虚拟语气,其谓语形式为“should+动词原形”,should可以省略。故答案为A。3.D考查虚拟语气。句意:昨晚我本应该去参加我堂妹的生日聚会,但是我没有空。but I was not available表示的是过去的真实情况,为含蓄的条件,相当于if I had been available(如果我有空的话)。此处为与过去情况相反的虚拟语气,主句应使用“would/might/could/should+have done”结构,故选D。【技巧点拨】 在做本题时,考生应先明白本题考查的是虚拟语气;其次应理清该句为虚拟条件句中的主句还是从句。表示对过去情况的虚拟时,条件句应使用过去完成时,主句应使用“would/might/could/should+have done”结构。4.A考查虚拟语气。句意:今天早晨下了倾盆大雨,我很高兴我们带了雨伞。是的,如果我们没带雨伞我们就要全身湿透了。由句意可知此处表示与过去事实相反的虚拟,故从句谓语动词用had done形式。从句补充完整为“if we hadnt taken an umbrella”。5.D句意:如果我们早订张桌子的话,我们就不会站在这儿排队了。根据语境可知,此处是if引导的虚拟条件句,从句叙述的是与过去事实相反的情况。谓语动词用had done。故正确答案为D项。6.B考查虚拟语气。句意:如果以前他花更多时间练习说英语的话,现在他英语就会说得好多了。由从句中的had spent可知从句与过去事实相反;由主句中的now可知主句与现在事实相反,故用would be。选B项。7.C考查虚拟语气。你认为George通过驾照考试了吗?没有。如果通过的话,昨天他就会开车来我们大学了。结合语境可知此处表示与过去事实相反,主句应用would/should/might/could have done结构。故选C项。8.C本题考查虚拟语气。句意:如果我当时想到你是认真的,我就不会笑了。根据主句中should not have laughed可知,if引导的是非真实条件句,表示与过去事实相反的假设,从句谓语结构应该为had done。9.D考查虚拟语气。句意:对不起,我现在太忙了。如果我有时间,我一定会陪你出去的。条件状语从句中的虚拟语气,用一般过去时表示与现在的事实相反。10.B考查虚拟语气。句意:如果我的车更可靠点的话,去年夏天我就会开车而不是坐飞机去拉萨了。根据主句的谓语动词would have driven可知,题干是表示与过去事实相反的虚拟语气,从句谓语动词用had done。11.D考查虚拟语气。句意:昨天我们在那个小山村迷路了,否则我们就能参观到更多的名胜古迹了。本题关键是从时间状语yesterday判断出是与过去事实相反的虚拟语气。前半句是个过去的客观事实“我们在那个小山村迷路”,后半句是对过去的虚拟用would have done。 12.D考查虚拟语气。句意:格蕾丝不想搬到纽约去,因为她想如果自己生活在那儿的话,就不能经常见到她的父母了。在表示对将来情况的一种假设时,从句用一般过去时,should do或were to do,故选D项。13.D考查虚拟语气的省略。句意:如果他们早知道接下来会发生什么的话,他们可能就会重新考虑一下了。had提前构成倒装,表示与过去事实相反,所以主句谓语用might have had。14.A考查虚拟语气。句意:孩子们哪儿去了?这顿饭快要吃不起来了。我但愿他们不要老是迟到。虚拟语气在wish宾语从句中的用法,题干中出现always,从句使用一般过去时表示与现在事实相反。15.A考查虚拟语气。句意:没有你的慷慨帮助,我是不可能度过那段痛苦的时期的。that bitter period表示过去的时间,与过去事实相反,用主语+should/would/could/might+have done表达。 16.D考查虚拟语气。句意:要不是因为他最近受伤,我们就把John的名字加进昨天的比赛名单中了。but for是含蓄虚拟语气的提示,yesterday表示过去的时间。与过去事实相反,谓语用should/would/could/might+have done表达,构成虚拟语气。17.D考查虚拟语气。句意:真可惜,你错过了那场有关核污染的讲座。我本可以去听的,但我当时忙于工作面试。与过去事实相反,谓语用should/would/could/might+have done表示虚拟语气。18.A本题考查虚拟语气。句意:如果我早知道这个电脑程序,就可以节省大量的时间和精力。根据句子的倒装特征判断,此处是省略了if的条件状语从句,原形是:If I had known about this puter program, a huge amount of time and energy从句与过去事实相反,故选择A项。19.D考查虚拟语气的用法。remend的宾语从句中用虚拟语气,即:(should+)v.,所以答案为D。三年模拟实战考点演练考点一: 情态动词的基本用法1.D考查情态动词。问句
