英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。
1、陈述语气
表示动作或状态是客观存在的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句中。如:
Iraq is an Asian country.
是。(肯定句)
2、祈使语气
表示说话人对对方的请求、,建议或命令。如:
Please come over here. 请到这边来。
Would you be so kind as to lend me a hand? 请帮个忙好吗?
3、虚拟语气
虚拟语气表示说话人的主观愿望、猜疑、建议或与事实不符的设等,而不表示客观存在的事实。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如:
If I were a bird,I would be able to fly in the air.
如果我是一只小鸟,我就能在空中飞行。
if的虚拟语气用法
if的虚拟语气用法分为三种:对过去语气的虚拟,对现在语气的虚拟,对未来语气的虚拟。if虚拟语气的基本准则就是把时态向前推一次。
对过去语气的虚拟:主句would/could/should/might +he done,从句if+主语+had done
对现在语气的虚拟:主句would/could/should/might +do,从句if+主语+was/were
对将来语气的虚拟:主句would/could/should/might +do,从句if+should do/if+were to do/if was/were
掌握好虚拟语气的用法对高中的学习生活有很大用处。
例:If I were a bird,I would fly above the ocean. If I were to obtain the gift,I would appreciate it a lot.

虚拟语气用法:
1、用在含蓄条件句中
句子中,设的情况不用条件从句表示出来,而是用一个介词短语来表示,句子的谓语形式也可遵循上表的规则。
这种用法也常见于or, or else, otherwise和but后面的分句中。
例如:Without music, the world would be a dull place.
2、用在错综时间条件句中
有时候,条件从句表示的动作和主句表示的动作发生的时间并不一致,这时,谓语动词的形式要根据表示的时间来调整,这种句子可称作错综时间条件句。例如:
If you hadn’t watched evision so late, you wouldn’t be so sleepy now.
此句为时间交错的虚拟条件句,从句表示与过去事实相反的设,主句则设与现在情况相反
3、用在wish后的宾语从句中
这种句子主要表示愿望,that常省略。若指现在或将来的愿望,从句用过去时;若指过去没有实现的愿望,从句用过去完成时。
例如:I wish I had learned to play chess.(与过去事实相反)
若wish 后的宾语从句中用would,可以表示请求,通常意味着说话人的不快或不满。
例如:I wish you would us.
4、用在if only感叹句中
当表示“但愿”,“要是…就好”时,它的用法和wish基本相同,只是更富有感彩,表示一时很难实现的愿望。
例如:If only I knew what you wanted.
5、用在以as if (as though) 引出的方式状语从句中
当表示过去想象中的动作或情况时,用过去完成时;当表示和现在事实相反或对现在情况有所怀疑时,用一般过去时。
例如:The old couple loved the orphan girl as if she had been their daughter.
6、用在某些虚拟的定语从句中
He was the very person I should he been wished to see.
7、用以表示说话人的主观愿望或选择,仅用在一些惯用句型的从句中
I’d rather they came tomorrow.
但had rather, would rather, would just as soon, would sooner等惯用语如用在简单句中,其后都用不加to的动词不定式。
例如:I’d rather die than give up my principle.
1、提出将来会发生的事:主句:主语+would/should/might/could+动词原形;
从句:should+动词原形/were to+动词原形;
2、提出现在的条件: 主句:主语+would/should/might/could+动词原形;
从句:动词过去式;
例句:If he studied at this school, he would know the enviornment around the school very much.
3、提出过去的未发生的条件:主句:主语+would/should/might/could he+动词过去分词
从句:had+动词过去分词
例句: If I had read the book, I would he told you about it.
