2.as引导非限制性定语从句。
as与which一样都可以引导非限制性定语从句,但是as引导的从句可以放在主句之前、主句之后,甚至还可以分割主句;
而which引导的非限制性定语从句只能放在主句之后。
另外as还有“正如、就像”之意。
Asismentionedabove,thenumberofthestudentsinseniorhighschoolsisincreasing.
Hewasadmittedtocollege,whichmadehisparentsveryhappy.
John,asyouknow,isawriter.
动词不定式
动词不定式是非谓语动词的一种,它没有人称和数的变化,在句子中不能独立作谓语,但它仍保持动词的特点,既可以有自己的宾语和状语。
动词不定式的构成:
to+动词原形
动词不定式作主语
动词不定式作主语时句子有以下两种
(1)把不定式置于句首。
如:
Togettherebybikewilltakeushalfanhour.
(2)用it作形式主语,把真正的主语不定式置于句后
Itwilltakeushalfanhourtogettherebybike.
常用句式有
①It+be+名词+todo
It‘sourdutytotakegoodcareoftheold.
②Ittakessb+sometime+todo
Howlongdidittakeyoutofinishthework?
③It+be+形容词+forsb+todo
Itisdifficultforustofinishwritingthecompositioninaquarterofanhour.
④Itseems+形容词+todo
Itseemedimpossibletosavemoney
动词不定式作宾语
●后面能接不定式作宾语的动词有:
agree,ask,choose,decide,forget,hope,learn,want,wish,wouldlike等。
Wehopetogettherebeforedark.我们希望天黑以前到那儿。
Thegirldecidedtodoitherself.那个姑娘决定自己做那件事。
动词不定式作宾语的注意事项(2点)
1.有些动词既可跟不定式作宾语,也可跟动名词作宾语,但含义不同:
remembertodo记住要做某事;
rememberdoing记得曾经做过某事
forgettodo忘记要做某事forgetdoing忘记曾经做过某事
stoptodo停下来去做某事stopdoing停止做某事
goontodo继续做另一件事goondoing继续做原来在做的事
Irememberseeingyousomewherebefore.
我记得以前在哪儿见过你。
Pleaseremembertoturnoffthelightwhenyouleave.
离开时请记得关好灯。
2.不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。
Hefounditverydifficulttogettosleep.
他发现很难入睡。
动词不定式作宾语补足语
1.后面能接to不定式作宾语补足语的动词有:
ask,order,teach,tell,want,wish,help等。
TheteachertoldustodoExercise1.
老师要我们做练习一。
Iwantbothofyoutogo.
我要你们俩去。
Wehelpedher(to)repairherbike.

2.使役动词let,have,make及感官动词see,watch,notice,hear,feel等要以不带to的不定式作宾补。
Let’shavearest.我们休息一会吧。
Isawhimcomein.我看见他进来了。
感官动词后既可跟不带to的不定式作宾补,也可跟v-ing作宾补,前者表示动作的全部过程已结束;
后者表示动作正在进行。
Isawhimcomedownstairs.我看见他下了楼。
(说明他下楼了这件事)
Isawhimcomingdownstairs.我看见他在下楼。
(说明他下楼时的情景)
动词不定式作定语
1、不定时要放在所修饰的名词、代词之后。
Wouldyoulikesomethingtoeat?
Hehasaimportantmeetingtohave.
2、如果动名词与所修饰的名词与代词之间构成逻辑上的动宾关系,因此若不定式的动词是不及物动词时要加上相应的介词
Theywantabigroomtolivein.
动词不定式作表语
动词不定式作表语的语法功能,在初中阶段不作为考查项目,但是往往会在完形填空或阅读理解中出现,所以对此有多了解会有助于你的阅读能力。
动词不定式放在系动词之后作表语;
Myjobistocleanthestreeteveryday.
HisdreamIstobeadoctor

1.作目的状语
Heranfasttocatchthefirstbus.
Hecamehereonlytosaygoodbyetous.
2.作结果状语
Hesearchedtheroomtofindnothing.
3.作原因状语

特殊疑问词+Todo往往与宾语从句相互转
Idon’tknowwhattodo.
=Idon’tknowwhatIshoulddo.
类似的疑问词还有
when,where,whom,which,how
动词不定式的否定形式
●动词不定式的否定式是在to前加not;
不带to的不定式则在动词前加not.如:
ZhangMingaskedmenottostayathomeallday.

Mymotherletmenotdoitbymyself.
