．虛擬語氣的特殊用法：

1．Suggest,advise

等動詞表示建議，要求，堅(jiān)持，命令等的意思時，其后的賓語從句須用虛擬語氣，其句子結(jié)構(gòu)如下：

suggest,advise,recommend,demand,require,insist,ask,urge,request,order,desire,move,propose等

+that+(should)+動詞原形e.g.

Hesuggestedthatthey(should)stopsmoking.

Hemadearequestthatthey(should)respecttherules.

注意：在此結(jié)構(gòu)中that不可省略；should省不省均可。上述動詞的名詞形式出現(xiàn)時，that引導(dǎo)的從句仍用虛擬語氣。

2．Itis(was)+necessary/apity

等+that引導(dǎo)的從句須用虛擬語氣,其句子結(jié)構(gòu)如下：

Itisimportantthatyou(should)followthedoctor’sorders.Itisrightthatyoushouldhavedoneyourhomework.Itis(was)+imperative,advisable,important,natural,strange，necessary,essential等+that+(should)+①動詞原形②動詞完成式3.It’s(high)timethat…+動詞過去式或should+動詞原形

e.g.Atruefriendwouldnotdosuchathing.(=Ifhewereatruefriend,he...)3.有時條件從句中的動作和結(jié)果從句中的動作發(fā)生的時間不一致.e.g.Ifhehadfollowedthedoctor’sadvice,hewouldbequiteallrightnow.IfIwereyou,Iwouldhavegonehome.Ⅴ.完成下列練習(xí)題:
