表語從句(ThePredicativeClause)

一、表語從句的定義：

表語從句就是用一個句子作為表語，放在連系動詞之后，充當復合

句中的表語，用來說明主語是什么或者怎么樣。Theproblemis

puzzling.主語連系動詞形容詞作表語

Theproblemiswhenwecangetapayrise.

主語連系動詞一個句子作表語一表語從句

二、表語從句的構成：系動詞+引導詞+簡單句

WhatIwanttosayisthatIamtired.

三、表語從句的用法

1.可接表語從句的連系動詞有：

1).最常用連系動詞：be(am;is/was;are/were)o一般在句子中譯成：“

日，，

7H...

Chinaisnolongerwhatsheusedtobe.

2).表變化的系動詞：get;turn;go;fall;become;grow;come;runo

用法注意：在英語中，系動詞一般只有一般現在時和一般過去時兩

種時態變化形式，沒有其他時態變化形式。但表變化的這類系動詞

除外，它們有各種時態變化。

Itisbecomingcolderandcolder.Thefoodhasgonebad.

此處還需注意的是become和turn后接表職業的名詞時冠詞的有無：

Twoyearslater,hebecameateacher.

但Twoyearslater,heturnedteacher.

另外，g。表變化時一般指事情向消極、不好的方面轉化。

3).所謂“感官動詞”:look;sound;taste;smell:fbeL般它們在句子中譯成:

“…起來；…

上去:此類系動詞為高考高頻詞。

Thefoodtastedgood.食物嘗起來很香。

Helookedsadlyatthepicture./Shelookedsadafterhearingthenews.

Tomtastedthefoodandittastedgood.

4).表狀態的系動詞：keep;stay;remain;一般在句子中譯成：“依然是;

保持”

Sheremainsloyaltoherfatherdespitehiscrueltytowardsher.

Whatalovelydaytoday!IlovefineweatherandThopeitwillstayfinefor

somedays.

Muchremainstobedone.

5).表像系動詞：seem;appear。一般在句子中譯成：，看起來像”、“似乎，

“好像”。

這兩個動詞有一個共同的特點，即如果要表達時態的變化，需要后

接不定式來完成。

Heseemedtohavecaughtcold.

Itappearstomethathewantstoteachusallhehas.

WhenFathercamein,Tomseemedtobeeatingsomething.

另外此處一句型轉換也要牢記：

Itseemedthathehadcaughtcold.

WhenFathercamein,itseemedthatTomwaseatingsomething.

6).終止系動詞：prove;tumouto一般在句子中譯成：“證實、證明、

結果為…”

Heproved(tobe)right./Theexperimentturnedoutsuccessful.

2.引導表語從句的關聯詞的種類：

1）從屬連詞ihat,ihat在表語從句中不充當任何句子成分，也沒有任何

意義。

ThetroubleisthatIhavelosthisaddress.

2）從屬連詞whether,as,asif/asthough引導的表語從句，有自己的含義,

但在從句中并不充當語法成分。

Thequestioniswhethertheywillbeabletohelpus.

Itlookedasifitwasgoingtorain.

注:從屬連詞if一-不用來引導逐語從句，但asif卻可引導表句從句。

Allthiswasovertwentyyearsago,blitit'sasifitwasonlyyesterday.

3）because,why引導的表語從句，有自己的含義，但在從句中并不充

當語法成分。

That'swhyhedidn'tunderstandme.

Ithinkitisbecauseyouaredoingtoomuch.

注意：'That/Itisbecause...”與“That/Itiswhy...”之間的不同在于，TTiat/Itis

because...”指原因或理由;“That/Itiswhy...”則指由于各種原因所造成的后

果。

Hedidnotseethefilmlastnight.Thatisbecausehehadtohelphislittlesister

withherhomework.Hehadseenthefilmbefore.Thatiswhyhedidnotseeit

lastnight.

4）連接代詞who,whom,whose,what,which;連接副詞where,when,how,

why它們分

Theproblemiswho/whomwccangettoreplaceher.（作賓語）

Thatwasuhalshedidthismorningonreachingtheattic.<作賓的）

ThequestionishewIcanpersuadeher（ojoinusintheparty.（作方式狀語）

Thequestionis」hichbookisthemostsuitableforusstudenls.（件定語）

5）使用虛擬語氣的表語從句

在表示建議、勸告、命令等含義的名詞后的表語從句，謂語動詞需用

“should+動詞原形”表示，should可省略。常見的詞有：advice,

suggestion,order,proposal,plan,idea等。

Mysuggestionisthatwe(should)startearlytomorrow.

3.注意：

1)表語從句一定要用陳述語序。

False:Thequestioniswhencanhearriveatthehotel.

Right:Thequestioniswhenhecanarriveatthehotel.

2)在有表語從句的復合句中，主句時態和從句時態可以不一致。

Right:ThequestioniswhowilltravelwithmetoBeijingtomorrow.

Right:Thequestioniswhyhecriedyesterday.

3)that在表語從句中一般在書面語中不可以省，但在口語中可以省

略oTheideais(that)weshallgotopicnicthisweek.

4)€Thatiswhy...”與“Thatisthereasonwhy...”同義，不過從語法結構上講,

“Thatisthereasonwhy..."中why弓I導的是一個定語從句，將其中的the

reason去掉則與叮hatiswhy...”結構一樣。

Thatis(thereason)whyIcannotagree.

5).當主語為Thereason(why…)時，表語從句的引導詞只能用that...

Right:Thereason(whyhewaslate)wasthathewascaughtintheheavyrain.

Wrong:Thereasonwhyheisabsentisbecauseheisill.
