虚拟语气和情态动词精讲◆【考情分析】英语中常用的情态动词主要有can,could,may,might,must,will,would,shall,should,ought to,dare,need,used to,had better等。
在学习情态动词时应注意以下几点:同一情态动词表示不同的意义的情况;情态动词后跟各种形式的用法;特别是注意“情态动词+完成式”是高考中的重点所在。
高考中的虚拟语气一般与情态动词结合进行考查。
每年高考试题中都会出现一定的题目。
◆【知识要点】★虚拟语气一、语气的定义和种类1.语气(mood):语气是动词的一种形式,表示说话人对某一行为或事情的看法和态度。
2.语气的种类1) 陈述语气:表示动作或状态是现实的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句。
如:Ø There are two sides to every question. 每个问题都有两个方面。
Ø Were you busy all day yesterday? 昨天一整天你都很忙吗?Ø How good a teacher she is! 她是多好的一位老师啊!2) 祈使语气:表示说话人对对方的请求或命令。
如:Ø Never be late again! 再也不要迟到了。
Ø Don’t forget to turn off the light.别忘了关灯。
3) 虚拟语气:表示动作或状态不是客观存在的事实,而是说话人的主观愿望、假设或推测等。
如:Ø If I were a bird, I could fly in the air.如果我是一只小鸟,我就能在空中飞行。
Ø I wish I could pass the examination.我希望我能通过考试。

如:can(能,会)、may(可以),以后我们还将学到must(必须)、should(应该)、would(应该、想要)等。
情态动词在运用时有以下三方面的特征:1.情态动词无主语人称及单复数的变化。
eg:They can play the piano.She can speak a little English.You may watch TV after supper.2.情态动词在句中运用时,后接动词原形。
eg:The girl can sing English songs.I can play Chinese chess.3.含情态动词的肯定句变为一般疑问句时,将情态动词提至句首,后加“?”;变否定句时,在情态动词后加上“not”即可。
eg:This boy can dance well.—Can this boy dance well?(一般疑问句)—Yes,he can./No,he can't.否定句)二、情态动词can的用法小结can是情态动词,意为“能;会”,表示某人或某物具备的能力,还可用来提出请求,没有人称和数的变化,后面直接接动词原形。
下面来看一下它的具体用法。
1.表示有能力做某事,意为“能;会”。
eg:I can speak English.我会讲英语。
He can play basketball.他会打篮球。
2.表示许可,意为“可以”。
eg:You can sit here.你可以坐在这儿。
下面一起来看一下can的句型变换:(1)变为否定句变为否定句时在情态动词can后加not,缩写为can't。
eg:She can't play the piano.她不会弹钢琴。
(2)变为一般疑问句变为一般疑问句时直接将情态动词can提到句首。
