 技巧点拨 ____________________________________________原则这样解惑

情态动词表示推测三步判断:(1)首先看是肯定句、否定句还是疑问句。肯定句中一般用must/may/might;否定句和疑问句中一般用can/could(2)然后看是对什么时间的推测;表示对现在的推测用情态动词+do表示对过去的推测用情态动词+have done(3)最后看句子语气的肯定程度must(十分肯定)>may(不太肯)>could/might(可能性较小)

情态动词表示推测的误用

高考对情态动词表示推测的考查基本集中在mustmaymightcancould的用法上。

要切记:对现在和将来的推测用情态动词+动词原形;对正在发生的动作的推测用情态动词+be doing;对过去的推测用情态动词+have done

 虚拟语气在条件句中的应用

Aaccomplished  Bhad accomplished

Cwould accomplish  Dwould have accomplished

D 解析:考查虚拟语气。句意:工人们没有被组织好否则的话他们会用那一半的时间完成任务的。此处otherwise表达了一种含蓄虚拟;otherwise前的内容所述的是过去的事实相当于if引导的条件状语从句If the workers had been better organized因此后半部分应用主语+would have done sth.的结构。故选D

Adrove  Bwould drive

Cwere to drive  Dhad driven

Ahad  Bhad had

Cwould have  Dwould have had

Bhave done

Cdid  

Dam doing

A 解析:考查虚拟语气。句意:打破窗户的是约翰。为什么你说得好像是我打破的似的?根据第一句话可知打破窗户的人并非故此处应该用虚拟语气表示与事实相反。根据broke可知这件事情发生在过去故用过去完成时态表示与过去事实相反。一般过去时态表示与现在的事实相反故排除C项。BD两项都不表示虚拟语气。

Awould not win  Bwould not have won

Cwould win  Dwould have won

B 解析:此处虚拟语气表示与过去事实相反句子谓语动词用would/should/could/mighthave done结构根据句意要用否定含义故选B。本句的条件是由介词短语(but for)表达的。

15If I ________ my umbrella with me when I came out this morning, I should not be wet now.

Atook  Bhad taken

Cwould have taken  Dwere to take

B 解析:考查虚拟语气。句意:如果我早上出门的时候带伞了的话我现在就不会被淋湿了。根据句意可知空处表示与过去事实相反的情况故选B
