☆重点句型☆

1.英语句型中的否认转移

在英语中，假如主句的动词是think,suppose,expect,believe,imagine之类的动词，其否认形式应转移到主句。构成反意疑问句时，主语是第一人称，以从句为准；主语是其它人称，以主句为准。idon'tthinkyou'reright,areyou?我认为你不对，不是吗？

marydoesn’texpectshecanhavealongholiday,doesshe?

练习：a.idon'tsupposeishallbebackuntil9o'clock,________________?

b.theyallthinkthatenglishisveryimportant,_______________?

c.idon’tbelievehecanaffordtobuyanapartment,_____________?

d.hedidn’tthinkthatthenewswastrue,________________?

e._________________________________________我认为你的答案是不对的，不是吗？

反义疑问句的答复是依据实际状况来答复的。确定答复：yes,ido.否认答复：no,idon't.留意:要前后保持相同，切不行说成“yes,idon't.”或“no,ido.

(1)---hissisterdidn’tattendthemeeting,didshe?

---______.shefellillthatday.

a.yes,shedid.b.no,shedid.c.yes,shedidn’td.no,shedidn’t

(2)----helikesplayingfootball,doesn’the?

---______.hedoesiteveryday.

a.yes,hedoesn’t.b.no,hedoesn’t.c.yes,hedoes.d.no,hedoes.

2.pierreandididhaveaverygoodtimeattheball.皮埃尔与我的确在舞会上玩得很欢乐。

助动词do/does/did+动词原形表示“的确，的确，必需”。时时用在确定句或祈使句中，起加强语气的作用。有人称和时态的变更。例如：

_______sendmee-mailimmediatelyyouarriveatbeijing.你一到北京，必需要给我发电子邮件

he__________smoketwopacksofcigaretteseveryday.他的确每天抽两包烟。

you________looknicetoday.你今日看起来真漂亮。

we________needhelpthosedays.在那些日子里我们的确须要帮助。

3.be(was/were)todo此构造表示支配、叮嘱、职责、义务、用途、可能性、命中注定等。

aknifeistocutwith.刀是用来切割的。(用途)

theywerenevertomeetagain.他们注定以后恒久不会见面。(命中注定)

4.tiethecornersofthehandkerchieftothepointsofthecross,andyouwillhaveanicestrongkite.

这种句式叫“祈使句+and/or+陈述句”构造，有时候，祈使句中的动词可省略。

workharder,andyou'llfinditnotdifficulttolearn.再用功一点，你就会发觉它不难学。

hurryup,oryouwillbelate.快一点，否那么你会迟到。

moreeffort,andyoucanfinishitintime.再加把劲，你会按时完成它。

6.havingrealisedthaticoulduseakitetoattractlightning,idecidedtodoanexperiment.

havingrealised是此时此刻分词的完成式，在句中作状语，表示该动作发生在谓语动词的动作之前，相当于whenihadrealisedthat…一般式v.-ing表示该动作与句子谓语的动作同时发生或在其后发生。其否认形式是在v-ing前加not。

练习：_______________________inclass,thegirlfeltveryhappy.那个姑娘在班上得到表扬，…

改错：(1)icanpickonmyfriendamongthecrowd.

(2)iwillpickyouoffatsixo’clock.(3)there’re10minutesleft.pleasepickoverspeed.
