1.在demand/order/require/request/insist/suggest/propose/advise/urge/intend/recommend等表示“建議、命令、要求、愿望”等詞后的賓語從句中常用虛擬語氣。從句中的謂語動(dòng)詞用(should)+do形式。
注意:1)當(dāng)suggest表示“暗示;表明”，insist表示“堅(jiān)持認(rèn)為”時(shí)，不用虛擬語氣，應(yīng)用陳述語氣。2)在suggestion，proposal，order，request，advice等名詞后的表語從句和同位語從句中常用虛擬語氣。從句中的謂語動(dòng)詞用(should)+do形式。
2.在 wish/even if/as if/would rather等后的從句中常用虛擬語氣。從句中的謂語動(dòng)詞用過去時(shí)。

1)he hesitated for a moment before kicking the ball,otherwise he _________ a goal.
a.had scored b.scored
c.would score d.would have scored
答案：d 根據(jù)otherwise可以判定要用虛擬語氣，對(duì)過去發(fā)生的事情的假設(shè)要用would have scored。
2)it is hard for me to imagine what i would be doing today if i _________ in love at the age of seven,with the melinda cox library in hometown.
a.wouldn’t have fallen b.had not fallen
c.should fall d.were to fall
答案：b 根據(jù)句意和i would be doing可以判定這是虛擬語氣。at the age of seven是表示過去的時(shí)間狀語，從句中的謂語要用had not fallen表示對(duì)過去情況的假設(shè)。
3)how i wish every family _________ a large house with a beautiful garden!
a.has b.had
c.will have d.had had
答案：b wish后接賓語從句，主句表示現(xiàn)在時(shí)，賓語從句的謂語動(dòng)詞要用一般過去時(shí)。

a.drove;didn’t get
b.drove;wouldn’t get
