1、陈述句的强调句型:It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其它部分。

e.g. It was yesterdaythat he met Li Ping.

2、一般疑问句的强调句型:同上,只是把is/ was提到it前面。

e.g. Was it yesterdaythat he met Li Ping?

3、特殊疑问句的强调句型:被强调部分(通常是疑问代词或疑问副词)+ is/ was + it + that/ who + 其它部分?

e.g. When and where was it that you were born?

4、强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调。

强调主语:It wasI that (who) met Li Ming at the railway station yesterday.

强调宾语:It wasLi Ming that I met at the railway station yesterday.

强调地点状语:It wasat the railwaystationthat I met Li Ming yesterday.

强调时间状语:It was yesterdaythat I met Li Ming at the railway station.

5、注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that, who,即使在强调时间状语和地点状语时也如此,that, who不可省略;强调句中的时态只用两种,一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时,用It was … ,其余的时态用It is … 。

(二)not … until … 句型的强调句

1、句型为:It is/ was not until + 被强调部分+ that + 其它部分

e.g. 普通句:He didn’t go to bed until/ till his wife came back.

强调句:It was not until his wife came backthat he went to bed.

2、注意:此句型只用until,不用till。但如果不是强调句型,till, until可通用;因为句型中It is/ was not … 已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了。


1、It is/ was … that … 结构不能强调谓语,如果需要强调谓语时,用助动词do/ does或did。

e.g. Dosit down. 务必请坐。

He didwrite to you last week. 上周他确实给你写了信。

Dobe careful when you cross the street. 过马路时,务必(千万)要小心啊!

2、注意:此种强调只用do/ does和did ,没有别的形式;过去时用did ,后面的谓语动词用原形。




e.g. You cannot eat your cake but have it.(it代替前面的cake)

Although we cannot see it, there is air all around us. (it代替后面的air)

They say he has left town, but I don’t believe it. (it代替前面They…town分句中的情况)


e.g. Yesterday we saw a big tree. It was fully twenty metres high. (it代替前面的tree)

The baby cried because it was hungry. (it代替前面的baby)


e.g. ---- Someone is knocking at the door, Peter.

---- Who is it?

---- It’s me.

---- Who are singing?

---- It is the children.

---- The light is still on in the lab. It must be the third-year students doing the experiment.


e.g. ---- Do you still have the bicycle?

---- No, I have sold it.

---- Is this knife yours?

---- No. It is Xiao Zhang’s. Mine is the oneon the desk.


e.g. The climate of South China is mild(温和的); I like itvery much.(it指the climate of South China)

The climate of South China is much better than thatof Japan.(that指the climate)



It is fine (rainy, windy, etc.).

It is noon.

It is a half hour’s walk to the factory.

It is eighteen square metres in area.

What does it matter?


用以帮助改变句子结构,使句子的某一成分受到强调。“It is (was) + 所强调的成分+ that (who) + 其它成分。”在这个句型中,it本身没有词义。详见“一、强调句”。


为了使句子平衡,常采用形式主语(或宾语)it ,而把真正的主语(或宾语)置于句子后面。通常引导词it与它所代替的句子成分中间要夹有某些词。

e.g. It takes half an hour to go there on foot.(It与to go there on foot之间夹有takes half an hour四个词)

We thought it strange that Mr Smith did not come last night. (it与that从句中间夹有strange)


e.g. You may depend on it that they will support you.(因为介词on之后一般不直接接that引导的宾语从句。注意:it不是多余的,不能当作错句)





e.g. (I) Thank you for your help.(括号内为省略的词语,下同)

(I) see you tomorrow.

(It) Doesn’t matter.


e.g. (There is) No smoking.(Is there) Anything wrong?Why (do you) not say hello to him?


e.g. ---- Are you going there?

---- I’d like to(go there).

He did not give me the chance, though he had promised to(give me the chance).


e.g. ---- Are you an engineer?

---- No, but I want to be.

---- He hasn’t finished the task yet.

---- Well, he ought to have.


e.g. ---- Are you thirsty?

---- Yes, I am (thirsty).


e.g. Let’s meet at the same place as (we met) yesterday.

---- Have you finished your work?

---- (I have) Not (finished my work) yet.



e.g. My father is a doctor and my mother (is) a nurse.

I study at college and my sister (studies) at high school.



e.g. (I’m) Sorry to hear that you are ill.

(It is a) Pity that he missed such a good chance.


e.g. ---- Is he coming back tonight?

---- I think so.

---- Is he feeling better today?

---- I’m afraid not.

这种用法常见的有:How so? Why so? Is that so? I hope so. He said so 及I suppose not. I believed not. I hope not等。(但I don’t think so比I think not更常用)。








e.g. I told him to sit down andwait fora moment.

②、某些使役动词(如let, make, have)及感官动词(如see, watch, notice, hear, feel, look at和listen to等)后面作宾语补足的不定式一定要省去to,但在被动语态中须把to复原。

e.g. ---- I saw the boy fallfrom the tree.

---- The boy was seen to fall from the tree.


e.g. The boy did nothing but play.

3、在某些状语从句中,从句的主语与主句主语一致时,可省去“主语 + be”部分。(参看“状语从句”有关部分)



e.g. The sooner (you do it), the better (it will be).




1、单词(多是副词),如:besides, however, otherwise, therefore, though等。

e.g. She is looking fit, though. 他看起来倒是健康。

I can, however,discuss this when I see you.


e.g. China and India, for example, are neighbours.

By the way, where are you from?


e.g. He is an honest man, I believe.

Jack, as far as I know, isn’t clever.



e.g. You know that I thinkyou are wrong. 我认为,你明白你错了。

What on earthdo you mean? 你究竟是什么意思?



e.g. He got the news from nobody knowswhere. 他这消息谁也不知道是从哪儿得来的。


下面这种复杂的特殊疑问句,也可认为包含有“插入语”。这种疑问句(有的语法书也称为“混合疑问句”或“连锁疑问句”)常用来征询对方对某一疑问点的看法、判断、认识、猜度或请求对方重复一遍说过的话。口语中出现频率极高。常用动词有say, suppose, guess, believe, consider, think, imagine 等。

e.g. How long did you sayshe would stay here?

When do you supposethey’ll be back?

How old did you thinkshe was


by the way 顺便说,顺便问一下;so far 到目前为止;and so on 等等;on the contrary 相反;no wonder 不足为奇;as a matter of fact 事实上;come along 快点,来吧;in other words 换句话说;as usual 如同以往;as a result 因此,结果。
