Unit3Ahealthylife-语法篇
It的用法
一、it作人称代词
1.it的最基本用法是作代词,主要指刚提到的事物,以避免重复:
Xi’anis a beautiful city,isn’t it?
2.也可以指动物或婴儿(未知性别的婴儿或孩子):
Isthisyourdog?
No,itisn’t.
二、it作非人称代词
it有时并不指具体的东西,而泛指天气、时间、日期、距离、价值、度量、温度、环境等,称为非人称的it:
1.指天气:
Itisalovelyday,isn’t it?
Itisabitwindy.
2.指时间:
Itwasnearlymidnightwhenshecameback.
3.指环境:
Itwasveryquietin the café.
4.指距离:
Itishalfanhour’s walk tothecitycentrefrommyhome.
5.指日期:
--What'sthedatetoday?
--It'sMay1,2007.
6.指季节:
Itissummernow.
7.指度量:
Itisabout5kilograms.
8.指价值:
---What'sthecostoftheT-shirt?
----Itis150yuan.
三、it用作形式主语
替代作主语的从句、动词不定式、动名词,而把真正作主语的从句、动词不定式、动名词置于句尾。
1.代作主语的动词不定式
(1)It+be+adj.+(forsb.)todosth.
此处adj.通常为描述事件的形容词:
easy,difficult,hard,necessary,unnecessary,possible,impossible,likely,unlikely,right,wrong,important,unimportant,legal,illegal,polite,impolite,clear,obvious,certain,suitable,proper,fit,useful,useless,dangerous…
Itisillegal(forateenager)todriveacarwithoutalicense.
(2)It+be+adj.ofsb.todosth.
此处adj.通常为描述人的形容词:
kind,unkind,nice,rude,cruel,considerate,thoughtful,thoughtless,careful,careless,silly,foolish,stupid,clever,wise,crazy.
It'skindofyoutohelpmewiththeproblem.
(3)It替代作主语的动名词的常见句型
It'snogood/usedoing…
It's(well)worthdoing…
It's(well)worthwhiledoing/todo
It'snousecryingoverspiltmilk.
2.it作形式主语替代主语从句
①It+be+adj.+clause
Itisclear(obvious,true,possible,certain…)that...
该句型中it是形式主语,真正的主语是that引导的主语从句,常译为“清楚(显然,真的……)”是主语从句最常见的一种结构。
例如:
Itisveryclearthathe’sroundandtalllikeatree.
②It+be+v-ed+that…=sb./sth.+be+todo
Itissaid(reported/learned/believed/thought/known/told/hoped.....)that...
该句型中的it仍是形式主语,真正主语是that引导的主语从句;该结构常译为“据说(据报道,据悉...)”。
Itisreportedthatanotherearthsatellitehasbeenputintoorbit.
③It+be+noun+从句
Itisapity/ashame+that...
该句型中,that后的从句一般用虚拟语气(should+动词原形),should可省去.表示出乎意料,常译为“竟然”。
没有这种意义时,则不用虚拟语气。
Itisapitythatsuchathing(should)happeninyourclass.
这种事竟然发生在你们班上,真是遗憾!
Itisapitythatheisill.他生病了,真遗憾!
四、it作形式宾语
当复合宾语中的宾语是不定式、动名词宾语从句时,往往把宾语放在它的补足语后面,而用it作形式宾语,放在宾语补足语之前。
该句型中的it作形式宾语,常用的动词有think,believe,make,find,consider,feel等。
Ithinkitnousearguingwithhim.我认为和他争吵没有用。
IfounditveryinterestingtostudyEnglish.我发现学英语非常有趣。
Hemadeitclearthathewasnotinterestedinthissubject.
他非常清楚地表示他对那门学科不感兴趣。
五、用于强调句型中
Itis/was +被强调部分+that/who...
Itisnotuntil+被强调部分+that...
Itwasfiveo’clock_________Igothome.
Itwasatfiveo’clock_______Igothome.
强调句用以强调主语,宾语,介词宾语以及状语。
强调人时用that和who/whom皆可
Itwasshewho/thathadbeenwrong.
Itwasthegirlwhom/thatImetjustnow.
ItwasTomtowhomtheteacherhadtalked.
ItwasonMondaynightthatallthishappened.
Itisnotuntil+被强调部分+that...
该句型也是强调句型。
主要用于强凋时间状语,译成汉语“直到……才……”,可以说是not...until...的强调形式。
例如:
ItwasnotuntilshetookoffherdarkglassesthatIrealizedshewasafamousfilmstar.
=NotuntilshetookoffherdarkglassesdidIrealizeshewasafamousfilmstar.
=Ididn’trealizeshewasafamousfilmstaruntilshetookoffherdarkglasses.
六、It常用的固定搭配
1.makeit
(1)在口语当中相当于succeed,表示:
成功、做到、说定、赶上、及时到达
It'shardtomakeittothetopinshowbusiness.
(2)在口语中相当于fixthedatefor,表示“约定好时间”例
—Shallwemeetnextweek?
—OK.WejustmakeitnextSaturday.
2.takeit/thingseasy
相当于Don‘tworryordon’thurry.用来劝告别人,表示“不要慌,别担心,沉住气”

3.Italldepends/thatalldepends在口语中,相当于ithasn‘tbeendecidedyet,表示“那得看情况,还没有定下来”
