虛擬語氣
l 虛擬語氣的使用范圍及判斷
一虛擬語氣表示一種不能實現(xiàn)的假設.該語法主要用于if 條件狀語從句.也可用于主語從句、表語從句、賓語從句等.
二 if 條件狀語從句中虛擬語氣的判斷
If 條件狀語從句有真實條件句和非真實條件句.假設條件可以實現(xiàn)的句子為真實條件句（如在陰天說if it rains,we would not go out）,反之為非真實條件句,要用虛擬語氣.
三假設條件一般為：
1） 與過去事實相反,從句謂語動詞用過去完成時,主句動詞為情態(tài)動詞＋完成時態(tài).
e.g.If I had come here yesterday,I would have seen him.
2） 與現(xiàn)在事實相反,從句謂語動詞用一般過去時,主句動詞為情態(tài)動詞＋動詞原形.
e.g.If I were a teacher,I would be strict with my students.
3） 與將來事實可能相反,從句謂語動詞用過去將來時,主句動詞為情態(tài)動詞＋動詞原形.
e.g.If it should snow tomorrow,they couldn’t go out.
主句謂語動詞為情態(tài)動詞（should,would,could）＋和相應的從句一致的動詞形式.
四 if 條件句中如果有were,should,had,可以省去if,并使用倒裝句序.
l 賓語從句中的虛擬語氣
一 wish后面賓語從句中的虛擬語氣：根據(jù)從句的意義來判斷：
1．與現(xiàn)在和將來相反的事實,從句謂語動詞用過去時態(tài)；
e.g.I wish I were a bird.
2．與過去相反的事實,從句謂語動詞用過去完成時態(tài).
e.g.I wished he hadn’t done that.
二表示“要求、建議、命令”等動詞后面的賓語從句中的虛擬語氣
從句用“should + 動詞原形”構成.而且should 可以省去.用于此結構的動詞有：advise,direct,agree,ask,demand,decide,desire,insist,order,prefer,propose,request,suggest等.
e.g.I insisted that he (should) go with them.
He suggest that a meeting (should) be held to discuss the matter.
He demanded that I (should) help him.
注意：當insist 表示“堅持認為”、suggest表示“表明,顯示”時,不用虛擬語氣.
e.g.He insisted that he was honest.
The look on his face suggested that he was quite satisfied with what I had done for him.
三 would rather + 從句
在這種結構中,從句的謂語動詞用過去形式表示虛擬.
e.g.I would rather you did this instead of me.
l 主語從句中的虛擬語氣
一 It be + 形容詞+ that….(should)….
用于該句型的形容詞有：necessary,good,important,right,wrong,better,natural,proper,funny,strange,surprising,etc.
e.g.It is necessary that we should get everything ready by the end of the week.
It’s natural that he should feel hurt.
一些名詞也可用于此結構中,如 a pity,no wonder,…..
二 It be + 過去分詞＋ that……(should)……
用于該結構中的過去分詞是表示“建議、請求、命令”等詞的過去分詞.如：desired,suggested,requested,ordered,proposed等.
e.g.It is desired that the building of the house be completed next month.
三 It is time (about time/ high time) that…..(過去時動詞形式或should + 動詞原形)…..
e.g.It is high time I went home now = It is high time I should go home now.
l 表語從句、同位語從句中的虛擬語氣
在suggestion,proposal,order,plan,idea,advice,decision等需要具體內(nèi)容解釋的名詞后的表語從句、同位語從句中,要使用虛擬語氣、其謂語動詞為：should + 動詞原形.連接從句的that 不能省略.
e.g.My suggestion is that we should go there at once.
What do you think of his proposal that we should put on a play at the English evening?
The proposal that we should stay longer in Shanghai was rejected.
