05 情态动词和虚拟语气-2021年新高考英语二轮复习语法及题型大全 (含答案)
如何判定情态动词和虚拟语气一、意义和语气判断法所谓意义判断法就是分析语境并确定应填情态动词的含义。
因此熟练掌握每个情态动词的意义和用法是答题的前提。
此外，情态动词主要表示说话人的语气、态度或情感，所以在解答此类试题时，要从说话者的角度去考虑问题，结合具体的语境来分析和判断，最后确定所需情态动词是否符合说话者的语气以及特定的情感需要。
【例1】(浙江卷) George ____________(not go) too far. His coffee is still warm.【分析】can’t/couldn’t have gone由下文的His coffee is still warm.可以看出，乔治应该是刚离开，不可能走太远，表示对过去发生的事情非常有把握的否定推测，故填can’t/couldn’t have gone。
二、时间判断法虚拟语气的考查重点在于判断句子是对现在、过去还是将来的动作进行虚拟。
判断出时间后再根据相应的结构或句型确定谓语动词的形式。
【例2】(天津卷)I wish I ____________(be) at my sister’s wedding last Tuesday, but I was on a business trip in New York then.【分析】had been句意：我真希望上周二参加了妹妹的婚礼，不过我当时正在纽约出差。
根据句中的but可知“我参加了妹妹的婚礼”只是一种假设，根据空后的时间状语last Tuesday可知，动作发生在过去，此处表示与过去事实相反的假设，故谓语用“had＋过去分词”结构。
故填had been。
三、情态动词和虚拟语气增分攻略①情态动词不能单独作谓语，需和后面的实义动词或be动词构成谓语：情态动词＋do/be；表对过去的猜测时用“情态动词＋have done”。
②情态动词后应接动词原形，后接形容词或名词时需与系动词be构成系表结构。

高中英语虚拟语气讲解及练习附答案
高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。
