第一篇：表語(yǔ)從句專項(xiàng)指導(dǎo)練習(xí)

表語(yǔ)從句

一、表語(yǔ)從句的定義：

表語(yǔ)從句放在連系動(dòng)詞之后，充當(dāng)復(fù)合句中的表語(yǔ)。

二、表語(yǔ)從句的構(gòu)成： 關(guān)聯(lián)詞+簡(jiǎn)單句

三、引導(dǎo)表語(yǔ)從句的關(guān)聯(lián)詞的種類：

1.可接表語(yǔ)從句的連系動(dòng)詞有be, look, seem, sound, appear等。China is no longer what she used to be.今日的中國(guó)不再是過(guò)去的中國(guó)了。

The question remains whether they will be able to help us.問(wèn)題還是他們能否幫我們。

At that time, it seemed as if I couldn't think of the right word.當(dāng)時(shí)，我似乎怎么也想不出一個(gè)恰當(dāng)?shù)淖盅蹃?lái)。

2.從屬連詞whether, as, as if / though引導(dǎo)的表語(yǔ)從句 He looked just as he had looked ten years before.他看起來(lái)還與十年前一樣。

It sounds as if someone is knocking at the door.聽(tīng)起來(lái)好像有人在敲門(mén)。

3.because, why引導(dǎo)的表語(yǔ)從句

That's because he didn't understand me.那是因?yàn)樗麤](méi)有理解我。(That's because...強(qiáng)調(diào)原因)

That's why he got angry with me.那正是他對(duì)我生氣的原因。(That's why...強(qiáng)調(diào)結(jié)果)what引導(dǎo)的主語(yǔ)從句表示結(jié)果或名詞reason作主語(yǔ)時(shí)，后面的表語(yǔ)從句表示原因時(shí)要用that引導(dǎo)，不宜用because。

The reason why I was sad was that he didn't understand me.我難過(guò)的原因是他沒(méi)有理解我。

4.連接代詞who, whom, whose, what, which, whoever, whatever, whichever 連接副詞 where, when, how, why。如：

The problem is who we can get to replace her.問(wèn)題是我們能找到誰(shuí)去替換她呢。

The question is how he did it.問(wèn)題是他是如何做此事的。

That was what she did this morning on reaching the attic.那就是她今晨上了閣樓干的。5.從屬連詞that。如：

The trouble is that I have lost his address.麻煩是我把他的地址丟了。6.使用虛擬語(yǔ)氣的表語(yǔ)從句

在表示建議、勸告、命令含義的名詞后的表語(yǔ)從句，謂語(yǔ)動(dòng)詞需用“should+動(dòng)詞原形” 表示，should可省略。常見(jiàn)的詞有：advice, suggestion, order, proposal, plan, idea等。My suggestion is that we(should)start early tomorrow.我的建議是我們明天一早就出發(fā)。

四、應(yīng)注意的問(wèn)題：

1.連系動(dòng)詞be，appear，seem，look等之后可以跟表語(yǔ)從句。It was because he didn't pass the exam.那是因?yàn)樗麤](méi)有通過(guò)考試。

It seems（that）he was late for the train.看來(lái)他沒(méi)搭上火車。It appears that she was wrong.看來(lái)她錯(cuò)了。

It seems to me that we should answer for this.在我看來(lái)，我們似乎應(yīng)該對(duì)此事負(fù)責(zé)。

It appears to her that he wants to teach us all he has.在她看來(lái)，他似乎要把他所會(huì)的都教給我們。2.引導(dǎo)表語(yǔ)從句的引導(dǎo)詞有以下幾類。1）wh-疑問(wèn)詞

My question is who left.我想問(wèn)的是誰(shuí)離開(kāi)了。What I wonder is when he left.我想知道他是何時(shí)離開(kāi)的。That's what he wants.那是他想要的。

This is where they once lived.這就是他們?cè)?jīng)住過(guò)的地方。

That is why he didn't come here.這就是他為何沒(méi)到這兒來(lái)的原因。2）whether My question is whether he left（or not）.我的問(wèn)題是他是否離開(kāi)了。注：if不能引導(dǎo)表語(yǔ)從句。3）that The fact is that he left.事實(shí)是他離開(kāi)了。

注：引導(dǎo)表語(yǔ)從句的連詞that間或可以省略。

The truth is（that）I didn't go there.事實(shí)是我沒(méi)去那兒。4）because，as，as if，as though

It's just because he doesn't know her.這是僅僅因?yàn)樗徽J(rèn)識(shí)她。Things are not always as they seem to be.事物并不總是如其表象。He looks as if he's tired.他好像累了。

第三篇：表語(yǔ)從句講解及專項(xiàng)練習(xí)

表語(yǔ)從句講解及專項(xiàng)練習(xí)

概念： 表語(yǔ)從句是在復(fù)合句中作表語(yǔ)的名詞性從句。

放在系動(dòng)詞之后,一般結(jié)構(gòu)是“主語(yǔ)+系動(dòng)詞+表語(yǔ)從句”

可以接表語(yǔ)從句的連系動(dòng)詞有be, look, remain, seem等。

★ The trouble is that we are short of money.困難是我們資金短缺。

★ That is why stone walls are used instead of fences around New England fields.這就是為什么在新英格蘭用石頭墻而不用柵欄的原因。

★ At that time, it seemed as if I couldn't think of the right word anyhow.當(dāng)時(shí),我似乎怎么也想不出一個(gè)恰當(dāng)?shù)淖盅蹃?lái)。

引導(dǎo)表語(yǔ)從句的詞：

從屬連詞that、whether、as though、as if（That引導(dǎo)表語(yǔ)從句時(shí)，在口語(yǔ)中，間或可以省略。）

關(guān)系代詞who, what, which, whom, whose, whatever, whoever, whomever, whichever等；

關(guān)系副詞when, where, why, how, however, whenever, wherever等。

※ 由從屬連詞that，whether引導(dǎo)的表語(yǔ)從句。

that在引導(dǎo)表語(yǔ)從句時(shí)無(wú)詞義，而whether有詞義，意為、“是否”。這時(shí)主句的主語(yǔ)常常是些抽象名詞，如question(問(wèn)題)，trouble(麻煩)，problem(問(wèn)題)，result(結(jié)果)，chance(可能性)，suggestion(建議)，idea(想法)，reason(理由)等。表語(yǔ)從句對(duì)主句主語(yǔ)進(jìn)行說(shuō)明、解釋，使主語(yǔ)的內(nèi)容具體化。

例如：

★ The trouble is(that)she has lost his money.麻煩的事是他丟了錢(qián)。

★

The question is whether we need more ice cream.問(wèn)題是我們是否還需要一些冰淇淋。

★

The problem was that it was too valuable for everyday use.問(wèn)題是它作為日常之用太貴重了。

★

What she couldn’t understand was that fewer and fewer students showed interest in her lessons.我們不能理解越來(lái)越少的學(xué)生對(duì)他的課不感興趣。

※ 由關(guān)系代詞引導(dǎo)的表語(yǔ)從句。

關(guān)系代詞who, what, which, whom, whose, whatever, whoever, whomever, whichever等引導(dǎo)表語(yǔ)從句，在句中作主語(yǔ)、賓語(yǔ)、表語(yǔ)，關(guān)系代詞不能省略。

例如：

★

The question is which of us should go.問(wèn)題是我們哪一個(gè)應(yīng)該去。

★

The problem was who could do the work.問(wèn)題是誰(shuí)能做這項(xiàng)工作。

★

That's what he is worrying about.那就是他在擔(dān)心的事。

★

That's what we should do.那是我們應(yīng)該做的。

※由關(guān)系副詞引導(dǎo)的表語(yǔ)從句。

關(guān)系副詞 when, where, how, why 除在句子起連接作用外，在從句中還充當(dāng)時(shí)間，地點(diǎn)，方式或原因狀語(yǔ)，本身具有詞義。

例如：

★Go and get your coat.It's where you left it.去把雨衣拿來(lái)。就在你原來(lái)放的地方。

★

I had neither a raincoat nor an umbrella.That’s why I got wet through.我們既沒(méi)傘也沒(méi)雨衣，這是我們淋濕的原因。

★

That is how mice ruin many stores of grain every year.那就是老鼠是怎樣每年損害大量糧食的。

★

That is what he is worried about.那就是他所擔(dān)心的。

※ 由連詞because，as if/as though等引導(dǎo)的表語(yǔ)從句。

★

It looked as if it was going to snow.看起來(lái)好像要下雪了。

★

That's because we never thought of it.這是因?yàn)槲覀儚奈聪脒^(guò)此事。

★

It seems as if he didn’t know the answer.好像他不知道答案。

注意

A.表語(yǔ)從句一定要用陳述語(yǔ)序。

False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B.不可以用if，而用whether 連接表語(yǔ)從句(as if 例外）。

引導(dǎo)賓語(yǔ)從句時(shí)可以互換if/whether 位于介詞后要用whether

位于句首時(shí)要用whether。

引導(dǎo)表語(yǔ)從句，主語(yǔ)從句，同位語(yǔ)從句時(shí)要用whether。

False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像賓語(yǔ)從句，在有表語(yǔ)從句的復(fù)合句中，主句時(shí)態(tài)和從句時(shí)態(tài)可以不一致。

Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D.that在表語(yǔ)從句中不可以省掉。

基本用法

表語(yǔ)從句只能置于主句之后，而主句的動(dòng)詞只能是聯(lián)系動(dòng)詞。

名詞性從句在be等系動(dòng)詞后作表語(yǔ)時(shí)被稱為表語(yǔ)從句

例如：

★The problem is how we can get the things we need.問(wèn)題是我們?cè)鯓幽芘轿覀冃枰臇|西。(how 在表語(yǔ)從句中充當(dāng)方式狀語(yǔ))

★

The scissors are not what I need.這把剪刀不是我所需要的。(what 在表語(yǔ)從句中充當(dāng)賓語(yǔ))

★

What I told him was that I would find him a good play.我告訴他的是我會(huì)給他找個(gè)好劇本。(what在主語(yǔ)從句中作直接賓語(yǔ)，that作為表語(yǔ)從句的引導(dǎo)詞在該表語(yǔ)從句中不充當(dāng)句子成分，不能省略)

★

That is what I want to tell you.那就是我想要對(duì)你講的。(what在表語(yǔ)從句中充當(dāng)直接賓語(yǔ))

★

That is why she failed to pass the exam.那就是她考試不及格的原因。(why 在表語(yǔ)從句中充當(dāng)原因狀語(yǔ))

概念： 表語(yǔ)從句是在復(fù)合句中作表語(yǔ)的名詞性從句。放在系動(dòng)詞之后,一般結(jié)構(gòu)是“主語(yǔ)+系動(dòng)詞+表語(yǔ)從句” 可以接表語(yǔ)從句的連系動(dòng)詞有be, look, remain, seem等。

★ The trouble is that we are short of money.困難是我們資金短缺。

★ That is why stone walls are used instead of fences around New England fields.這就是為什么在新英格蘭用石頭墻而不用柵欄的原因。

★ At that time, it seemed as if I couldn't think of the right word anyhow.當(dāng)時(shí),我似乎怎么也想不出一個(gè)恰當(dāng)?shù)淖盅蹃?lái)。

引導(dǎo)表語(yǔ)從句的詞：

從屬連詞that、whether、as though、as if（That引導(dǎo)表語(yǔ)從句時(shí)，在口語(yǔ)中，間或可以省略。）關(guān)系代詞who, what, which, whom, whose, whatever, whoever, whomever, whichever等； 關(guān)系副詞when, where, why, how, however, whenever, wherever等。

※ 由從屬連詞that，whether引導(dǎo)的表語(yǔ)從句。

that在引導(dǎo)表語(yǔ)從句時(shí)無(wú)詞義，而whether有詞義，意為、“是否”。這時(shí)主句的主語(yǔ)常常是些抽象名詞，如question(問(wèn)題)，trouble(麻煩)，problem(問(wèn)題)，result(結(jié)果)，chance(可能性)，suggestion(建議)，idea(想法)，reason(理由)等。表語(yǔ)從句對(duì)主句主語(yǔ)進(jìn)行說(shuō)明、解釋，使主語(yǔ)的內(nèi)容具體化。

例如：

★ The trouble is(that)she has lost his money.麻煩的事是他丟了錢(qián)。

★

The question is whether we need more ice cream.問(wèn)題是我們是否還需要一些冰淇淋。

★

The problem was that it was too valuable for everyday use.問(wèn)題是它作為日常之用太貴重了。

★

What she couldn’t understand was that fewer and fewer students showed interest in her lessons.我們不能理解越來(lái)越少的學(xué)生對(duì)他的課不感興趣。

※ 由關(guān)系代詞引導(dǎo)的表語(yǔ)從句。

關(guān)系代詞who, what, which, whom, whose, whatever, whoever, whomever, whichever等引導(dǎo)表語(yǔ)從句，在句中作主語(yǔ)、賓語(yǔ)、表語(yǔ)，關(guān)系代詞不能省略。

例如：

★

The question is which of us should go.問(wèn)題是我們哪一個(gè)應(yīng)該去。

★

The problem was who could do the work.問(wèn)題是誰(shuí)能做這項(xiàng)工作?！?/p>

That's what he is worrying about.那就是他在擔(dān)心的事?！?/p>

That's what we should do.那是我們應(yīng)該做的。

※由關(guān)系副詞引導(dǎo)的表語(yǔ)從句。

關(guān)系副詞 when, where, how, why 除在句子起連接作用外，在從句中還充當(dāng)時(shí)間，地點(diǎn)，方式或原因狀語(yǔ)，本身具有詞義。

例如： ★Go and get your coat.It's where you left it.去把雨衣拿來(lái)。就在你原來(lái)放的地方。

★

I had neither a raincoat nor an umbrella.That’s why I got wet through.我們既沒(méi)傘也沒(méi)雨衣，這是我們淋濕的原因。

★

That is how mice ruin many stores of grain every year.那就是老鼠是怎樣每年損害大量糧食的。

★

That is what he is worried about.那就是他所擔(dān)心的。

※ 由連詞because，as if/as though等引導(dǎo)的表語(yǔ)從句。

★

It looked as if it was going to snow.看起來(lái)好像要下雪了。

★

That's because we never thought of it.這是因?yàn)槲覀儚奈聪脒^(guò)此事?！?/p>

It seems as if he didn’t know the answer.好像他不知道答案。

注意

A.表語(yǔ)從句一定要用陳述語(yǔ)序。

False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B.不可以用if，而用whether 連接表語(yǔ)從句(as if 例外）。引導(dǎo)賓語(yǔ)從句時(shí)可以互換if/whether 位于介詞后要用whether 位于句首時(shí)要用whether。

引導(dǎo)表語(yǔ)從句，主語(yǔ)從句，同位語(yǔ)從句時(shí)要用whether。

False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像賓語(yǔ)從句，在有表語(yǔ)從句的復(fù)合句中，主句時(shí)態(tài)和從句時(shí)態(tài)可以不一致。

Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D.that在表語(yǔ)從句中不可以省掉。基本用法

表語(yǔ)從句只能置于主句之后，而主句的動(dòng)詞只能是聯(lián)系動(dòng)詞。

名詞性從句在be等系動(dòng)詞后作表語(yǔ)時(shí)被稱為表語(yǔ)從句

例如：

★The problem is how we can get the things we need.問(wèn)題是我們?cè)鯓幽芘轿覀冃枰臇|西。(how 在表語(yǔ)從句中充當(dāng)方式狀語(yǔ))★

The scissors are not what I need.這把剪刀不是我所需要的。(what 在表語(yǔ)從句中充當(dāng)賓語(yǔ))★

What I told him was that I would find him a good play.我告訴他的是我會(huì)給他找個(gè)好劇本。(what在主語(yǔ)從句中作直接賓語(yǔ)，that作為表語(yǔ)從句的引導(dǎo)詞在該表語(yǔ)從句中不充當(dāng)句子成分，不能省略)

★

That is what I want to tell you.那就是我想要對(duì)你講的。(what在表語(yǔ)從句中充當(dāng)直接賓語(yǔ))

★

That is why she failed to pass the exam.那就是她考試不及格的原因。(why 在表語(yǔ)從句中充當(dāng)原因狀語(yǔ))

例題精析： ［考題1］ The traditional view is ____ we sleep because our brain is “programmed” to make us do so.(2007上海)A.when B.why C.whether D.that ［答案］ D

［解析］ 下劃線處之后是包含一個(gè)原因狀語(yǔ)從句的表語(yǔ)從句，如果看不出它是充當(dāng)整個(gè)句子結(jié)構(gòu)的表語(yǔ)從句將難以把握整個(gè)句子的意思。因此，應(yīng)選擇可引導(dǎo)名詞性從句且不充當(dāng)任何成分的that。

［考題2］ You are saying that everyone should be equal, and this is ____ I disagree.(2004)A.why B.where C.what D.how ［答案］ B

［解析］ 下劃線處的引導(dǎo)詞引導(dǎo)系動(dòng)詞is后的表語(yǔ)從句并在該表語(yǔ)從句中充當(dāng)?shù)攸c(diǎn)狀語(yǔ)(“disagree”屬于不及物動(dòng)詞，“I disagree”本身是完整的主謂結(jié)構(gòu))，下劃線應(yīng)填入引導(dǎo)詞where，表語(yǔ)從句“where I disagree”的意思是“我不同意之處、我不同意的地方”。

［考題3］ — I drove to Zhuhai for the air show last week.— Is that ____ you had a few days off?(1999)A.why B.when C.what D.where ［答案］ A

［解析］ 下劃線處的引導(dǎo)詞引導(dǎo)與系動(dòng)詞is連用的表語(yǔ)從句并在該表語(yǔ)從句中充當(dāng)原因狀語(yǔ)，下劃線應(yīng)填入表示“因此……”(指因某種原因所造成的結(jié)果)的引導(dǎo)詞why。

［考題4］ ____ she couldn’t understand was ____ fewer and fewer students showed interest in her lessons.(2000上海)

A.What;why B.That;what C.What;because D.Why;that ［答案］ A

［解析］ 第一個(gè)下劃線處的引導(dǎo)詞引導(dǎo)主語(yǔ)從句并在該主語(yǔ)從句中充當(dāng)賓語(yǔ)，特指她所不理解的事情，應(yīng)填入關(guān)系代詞型的引導(dǎo)詞what； 第二個(gè)下劃線處表示“因此……”(指因某種原因所造成的后果，由why引導(dǎo)對(duì)應(yīng)的名詞性從句)而不是“為什么……”(指原因、理由，由because引導(dǎo)對(duì)應(yīng)的名詞性從句)，應(yīng)填入引導(dǎo)詞why。

［考題5］ ____ made the school proud was ____ more than 90% of the students had been admitted to key universities.(2003上海春)

A.What;because B.What;that C.That;what D.That;because ［答案］ B

［解析］ 第一個(gè)下劃線處的引導(dǎo)詞引導(dǎo)主語(yǔ)從句并在該主語(yǔ)從句中充當(dāng)主語(yǔ)，特指令校方驕傲的事情，應(yīng)選用關(guān)系代詞型的引導(dǎo)詞what； 第二個(gè)下劃線處引導(dǎo)表語(yǔ)從句表示原因、理由，應(yīng)由that引導(dǎo)對(duì)應(yīng)的名詞性從句。

［考題6］ — Are you still thinking about yesterday’s game? — Oh, that’s ____.(2003北京春)A.what makes me feel excited B.whatever I feel excited about C.how I feel about it D.when I feel excited ［答案］ A ［解析］ A選項(xiàng)的意思是“令我感覺(jué)激動(dòng)的事物”； B選項(xiàng)的意思是“我覺(jué)得激動(dòng)的任何事物”； C選項(xiàng)的意思是“我對(duì)它感覺(jué)的方式”； D選項(xiàng)的意思是“令我感覺(jué)激動(dòng)的時(shí)間”。四個(gè)選項(xiàng)中A最適合跟代表“game”的主語(yǔ)that對(duì)應(yīng)，充當(dāng)表語(yǔ)從句。
