高二英语选修七单元知识点大全集锦 1

1)句首为否定或半否定的词语，如no,not,never,seldom,little,hardly,atnotime,innoway,notuntil…等。

everhaveIseensuchaperformance.

otuntilthechildfellasleepdidthemotherleavetheroom.

当Notuntil引出主从复合句，主句倒装，从句不倒装。

注意如否定词不在句首不倒装。

Ihaveneverseensuchaperformance.

典型例题

1)WhycantIsmokehere?

Atnotime___inthemeeting-room

A.issmokingpermittedB.smokingispermitted

C.smokingisitpermittedD.doessmokingpermit

答案A.这是一个倒装问题。当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。这些否定词包括no,little,hardly,seldom,never,notonly,notuntil等。本题的正常语序是

mokingispermittedinthemeeting-roomatnotime.

2)Notuntiltheearlyyearsofthe19thcentury___whatheatis.

A.mandidknowB.manknowC.didntmanknowD.didmanknow

答案D.看到Notuntil…的句型，我们知道为一倒装句，答案在C，D中选一个。

改写为正常语序为，Mandidnotknowwhatheatisuntiltheearlyyearsofthe19th.现在将not提前，后面就不能再用否定了,否则意思就变了。

以否定词开头作部分倒装

如Notonly…butalso,Hardly/Scarcely…when,Nosooner…than

ot only did here fuse thegi ft,healsoseverelycriticizedthesender.

Hardly had she gone out when a student came tovisither.
