表语从用法
1.定义:用作表语的从句叫做表语从句
2.引导表语的从句的关联词的种类
(1)从属连词ubleisthatIhavelosthisaddress.
Thereasonwasthathewaslateforschool.
(2)从属连词whether,as,asif
Helookedjustashehadlookedtenyearsbefore.
Thequestioniswhethertheywillbeabletohelpus.
注:从属连词if一般不用来引导表语从句,但asif却可引导表语从
句。Allthiswasovertwentyyearsago,butit’sasifitwasonlyyesterday.
Thekeyiswhetherwecansolvetheproblem.
Itlookedasifitwasgoingtorain.
注:能跟表语从句的谓语动词一般为系动词be,em,look,sound等
Helookedjustashehadlookedtenyearsbefore.
Itsoundsasifsomeoneisknockingatthedoor.
(3)连接代词who,whom,who,what,which,whoever,whatever,
whichever在表语从句中做主语、宾语等。
Theproblemiswhowecangettoreplaceher.
Thatwaswhatshedidthismorningonreachingtheagreement.
Myquestioniswholeft.
(4)连接副词where,when,how,why
wheretheyoncelived.
Thatiswhyhedidn’tcomehere.
Thequestionishowhedidit.
(5)连词becau可引导表语从句。注意:becau可引导表语从句,
但与之同义的since,as,for等不用于引导表语从句。
Ithinkitisbecauyouaredoingtoomuch.
It’sjustbecauhedoesn’tknowher.
That’sbecauhedidn’tunderstandme.(That’sbecau…强调原因)
That'swhyhegotangrywithme.(That’swhy…强调结果)
注意:在一些表示“建议,劝说,命令”的名词后面的表语从句中,
谓语动词用虚拟语气.Should+动词原形表示,should可省略。
Mysuggestionisthatwe(should)startearlytomorrow.
一坚持(insisit)二命令(command,order)三建议(suggest,advi,
propo)四要求(desire,demand,require,request)
四.注意事项(重点看)
1.表语从句要用陈述语序。
Thatiswherethefamousscientistwasborn.
Thisiswhysheissohappytoday.
和what在引导的表语从句
that本身没有词义,在句中只起连接作用,不充当句子成分;what
则表示“所…的(人或事)”,在表语从句中充当主语或宾语等。
Thatfacetisthatmorethanventypercentoftheearth’ssurfaceis
coveredbywater.
Whathetoldyouwaswhathadbeendiscusdatthemeeting.
与whether均意为“是否”引导的表语从句是,只能用whether,
不能用if。Thequestioniswhetherwecanfinishourworkby
tomorrowevening.
4.语气
(1)主语为advice,order,idea,notion,proposal,suggestion,request等
一些表示“建议,劝说,命令”的名词,之后的表语从句中,
谓语动词用虚拟语气。Should+动词原形表示,should可省略。
Mysuggestionisthatwe(should)startearlytomorrow.
Ouronlyrequestisthatthisshouldbettledassoonaspossible.
(2)asif/though引导的表语从句时,从句谓语多用虚拟语气。这是因
为从句中的情况与事实不相符。
具体来说,如果从句表示与现在事实相反,谓语动词用一般过去式;
如果从句表示与过去事实相反,谓语动词“had+done”,如果从句表示
将来的可能性不大,用would(might,could)+动词原形。
LiLeiisnowinanewjackethelooksasifhewereanAmericanboy.
Thegirlisgivingusavividdescriptionofthemoon.
Itemsasifshehadbeentothemoonmanytimes.
但是,如果asif,asthough引导的表语从句所表示的与事实相符,从
句则用陈述语气。
sasifitisgoingtorain.
5.时态不像宾语从句,在有表语从句的复合句中,主语时态和从
句时态可以不一致。
ThequestioniswhowilltravelwithmetoBeijingtomorrow.
Thequestioniswhyhecriedyesterday.
系动词分类:
一.根据系动词后所跟结构,我们可以把英语系动词分为两大
类:完全系动词(其后只能跟表语动词,如be,em)和半
系动词(其后既跟表语作系动词用法,也可以跟宾语或状语
作实义动词用,如look)
1)Helookedsadlyattheboy.(看着,实义动词用法)
Helooksacleverboy.(看起来,系动词用法)
2)Helooksatacleverboy.(看着,实义动词用法)
在英语中,某一动词是多义词,既有实义动词用法,又有系动词用法。
二.根据系动词的意义,我们把英语系动词分为四类:
A.五大感官系动词B.状态系动词C.动态系动词D.双谓语系动词
“看起来像是“,后接adj,n.分词,介词短语,不定式等。
Thegirlbitherlipsandlookedthoughtful.
“听起来”,后接adj,分词。Theflowersmellsweet.
“听起来“,后接adj,分词。Themusicsoundssweet.
“尝起来“,后接adj,分词。Theapplestasteverygood.
①“摸起来,给….感觉”;②“觉得”,后接adj,p.p
Youwillfeelbetterafteranight’ssleep.
B.状态系动词:
,“是“,属完全系动词。Iamastudent.
,“似乎,好像“,完全系动词。Theyemquitehappy.
,“显得,看起来好像”,半系动词。Itappeared(tobe)atruestory.
,“保持…的状”,半系动词,后接adj或介词短语。
You’dbettergotobedandkeepwarm.
,“仍是”,半系动词。Iremainedsilent.
“保持(某种状态)”,半系动词,后接adj,过去分词。
Thewindowstayedopenallthenight.
“证明是”,半系动词,后接adj,n
Thetreatmentprovedtobesucessful.
C.动态系动词:都属于半系动词,描述状态变化过程。
“变成,变得……起来”,后接形容那个词,分词,介词短语。
Thedaysaregettinglongerandlonger.
“进入(某种状态),成为“,后接以下形容词:asleep,lame,silent,
ill,sick,men,unabletoexpresshimlf,fellsilent.
Myfatherfellillanddied.
“渐渐变得…..起来,长得”It’sgrowingwarm.
“转变成(新的与原来完全不同的色彩或性质),变质(色)”。
Mapletreesturnredinautumn.
Itwascloudythismorning,butfortunatelyithasturnedfien.
,“变成(某种坏的状态)”
erialhasgoneafunnycolour.
Go之后常接adj.还有:bad,blind,wild,wrong,sour,hard,hungry,mad,
red,with,anger,white,pale,blue,grey
”变成,成为(好坏均可的情况)”
meangrywithme.
Theybecamegoodfriends.
,“变成为(已知的状态),证实为”,后接形容词或前缀un-
的过去分词作表语,表示状态或情况的变化。
Hiswishtobecomeapilothascometrue.
后面接的形容词还有apart,dear,natural,open,short,right,unstuck,untied.
“变成”,后接ceranhigh.
,“达到某种状态,后接形容词,如:sure,certain,merry,bold,
makecertainoffacts.
D.双谓语系动词此类系动词既有系动词功能,后接表语,又保
留原实义动词本身的含义。
ppedandstoodquitestill.
iedyoung.
inuedsilent.
