强调句型中,时间和地点全用THAT而不能用WHEN,WHERE

强调句型中,时间和地点全用THAT而不能用WHEN,WHERE
举例吧

句型结构：
It is / was + 被强调部分+ that / who /whom +句子剩余部分…
? 这个句型用来强调除谓语以外的各种句子成分,被强调部分必须放在it is/was 后面,如果强调的部分是人,可以who/whom 来代替that.
如：They will have a meeting in the hall tomorrow.
? 强调主语:
It is they that/who will have a meeting in the hall tomorrow.
? 强调宾语:
It is a meeting that they will have in the hall tomorrow
? 强调地点状语:
It is in the hall that they will have a meeting tomorrow
? 强调时间状语:
It is tomorrow that they will have a meeting in the hall.
强调句型是英语中常用句子结构,又是高考中的常见考点,其基本结构为：It + be+ 被强调部分＋that＋句子其余部分.现将其用法归纳如下:
1. 强调句型中,能够被强调的句子成分通常为主语、状语、宾语等,不能用来强调谓语动词、表语、补语、让步状语、条件状语等.
例如 It was in the park that I mat my old teacher yesterday. (强调地点状语)
It is Mr. Smith that thinks Tom is a clever boy. （强调主语）
2． 强调句型中,连接词一般用that,如被强调的部分是人,也可用who/whom,其他一律用that,不能用which, where, when等,即使被强调的是物、时间状语或地点状语.
例如 It was at the gate that we met the inspectors this morning.
It is our head-teacher that/ who/whom we often turn to for help.
3． 强调结构中,无论被强调的是人还是物,单数还是复数,be动词一律用单数is/was形式,如果原句的谓语动词是一般过去时,就用was; 是一般现在时,就用is.也可以用"情态动词＋be"形式.
例如 It was the farmers that lived a hard life before liberation.
It might be yesterday that John bought a book for Mary.
4. 强调句型也有疑问句形式,包括一般疑问句、特殊疑问句和反意疑问句.一般疑问句的强调形式,只需将is/ was 提前,移至句首即可,即：Is/ Was it … that ….特殊疑问句的强调形式,须将陈述句变成一般疑问句,再在句首加上疑问词,即：疑问词（被强调部分）＋is/was + it + that + 句子其余部分.
例如 Was it last year that the building was completed?
Where was it that you met your English teacher?
It was the day before yesterday that you lost the money, wasn't it?
5. not … until…结构在强调句型中的运用：until引导的时间状语从句,也可以用在强调句型中,但主要是其否定形式,如用在强调句型中,必须将not前移,写成It is/was not until … that … .
例如 It was not until the class began that he came in.
It was not until last Friday that he finished reading the book.
6. 当强调的是主语时,其谓语动词应和被强调的人和物保持人称、数的一致.如果被强调的主语是人称代词,宜用主格,间或也可用宾格.
例如 It is I who am going to attend the meeting.
It was I/me who cleaned the classroom.
7. 强调句型最容易与定语从句、主语从句和状语从句一起考查,应是学习和复习的重点.一般说来,如果把句子中的It is/ was … that去掉,稍加调整语序,能还原成完整句子,并且句子意思依然完整,则为强调句型；否则,应为其他句式.
例如 It was a small house that I used to live in. (定语从句)
It was at the school gate that I met an old friend of mine.（强调句型）
高一册第19单元的语法重点是it在强调句型中的用法,这也是高考的重要考点.为了强调句子某一成分(除谓语外),将这一成分置于"It is (was)... that (who)..."这一句型中is (was) 之后,如果强调部分是人,既可用that又可用who连接,其余的全用that.这一句型也可用于一般疑问句、否定句和特殊疑问句.其特点是：去掉It is (was) 及 that (who)这几个标志词之后,在不添词、不减词的前提下能重新排列成一个完整的句子.现通过分析高考试题,体会it在强调句型中的用法,以期对同学们有所帮助.
英语中有时为了需要,经常要强调句子中的某一成分,这时,就要用到一些强调句型.英语中常见的用来表示强调的句型有以下几种.
一、用助动词do ,did does强调谓语.
用助动词do ,did does放在一般现在时和一般过去时的句子中动词原形前,以强调谓语.例如：
He did tell all that had happened to him. 他确实把发生的事情都说了.
She does get up early. 她的确常起得很早.
Do be careful next time. 下次务必要小心.
二、用倒装句来强调以加强语气.
Never have I seen such a wonderful film. 我从来没看过如此精彩的电影.
So hard did he study that he could easily pass the examination.
他那么努力才能轻易通过考试.
三、用 what来加强语气.
He needs money. 他所需要钱.
What he needs is money.他所需要的是钱.
Learning and knowledge are important to us, but what is more important is a noble character.学问和知识很重要,但更重要的是高尚的品格.
四、用in the world, on earth, at all等介词短语来表示强调,常用在疑问句中,与ever同义.
What in the world are you doing in my car? 你究竟在我的车里做什
么?
How on earth did she manage that? 她究竟怎么办到的呢?
Are you at all worried about the forecast? 对这项预报你不担点儿
心吗?
If you ever visit London, you must come and stay with us. 你要是
来伦敦,一定要来我们这来住住.
五、用形容词very, only, single, such等来修饰名词来表示强调.
This is the very thing I’m after. 这正是我要找的东西.
You are the only person here who can help us. 你是这儿唯一能帮我
们的人.
Not a single mistake did he make in the exam. 他在考试中没出一个
错.
六、用It is /was….that来强调主语,宾语,状语
用It is/was +被强调部分+that+句子的其他成分（如指人,that也可以用who, whom）来强调句子的主语,宾语,状语.
例如：I met him in the street this morning. 今天早上我在大街上遇到了他.
It was I who met him in the street this morning.（强调主语）
It was him that I met in the street this morning.（强调宾语）
It was in the street that I met him this morning.（强调地点状语）
It was this morning that I met him in the street.（强调时间状语）
It was because he was ill that he didn’t attend the meeting.(强调原因状语)
强调句型需要注意的几点：
1、如果原句中谓语动词使用的是现在范畴的时态（一般现在时、现在进行时、现在完成/现在完成进行时、一般将来时、将来进行时、将来完成时等）用It is…that .如果原句中谓语动词为过去范畴的时态（一般过去时、过去进行时、过去完成时、过去将来时等）则用It was…that .有时be前可以使用表示推测的情态动词构成结构.
It is not everyone that can draw well.不是每个人都能画得好的.
It was for his eyes that we asked him not to read in the sun.
我们是为他的眼睛着想才叫他不要在太阳下看书的.
It must be Jack who let out the secret.肯定是杰克泄露了秘密.
2、强调主语用人称代词主格,强调宾语用宾格.
It was I who gave you the book.(不用me)
It was I not him who am your best friend.(谓语与被强调词保持主谓
一致)
It was him that they telephoned.(强调宾语用宾格)
3、即使被强调成分是句子中的时间状语,地点状语,原因状语等,也
不能用when,where, because要用that.
（1） It was after the war was over that Einstein was able to come back to his research work again.
战争结束后爱因斯坦才能重新进行他的研究工作.
（2） It was in Athens that the 2004 Olympic Games were held. 2004
年奥运会是在雅典举行的.
（3） It was because of the traffic jam that the chairman cam late.主席是因为堵车才来迟的.
4、如果被强调的成分有同位语,同位语也应提前.
It was from him, our English teacher, that we learned this English
song.我们从英语老师那学会了这首歌.
5、Not until句型怎么强调?
当被强调的是not…until句型时,应将not置于until之前,主句由否定句改为肯定句.
We didn’t recognize her until she took off her glasses.
她把眼镜拿了,我们才认出她.
It was not until she took off her glasses that we recognized her.
注意与下面一句的区别：
Not until she took off her glasses did we recognize her.
此句为not位于句首,要主谓倒装.
6、疑问句中的强调句型.
其一般疑问句形式是：Is／Was it+被强调成分+who／that
其特殊疑问句形式是：疑问词+is／was+被强调成分+that...

举行的吗?

7、与定语从句连用的强调句型.

他们是在他祖父曾经住过的房子里找到那张旧照片的吗?
--Where did you meet him? 你在那遇到他的?
--It was in the hotel where he stayed. 在他住的旅馆里.（本句后省略了that I met him）
8、与其他一些句型结构的区别.
（1）与状语从句的区别.
It was at 7 o’clock that I arrived. （强调句型,强调时间状语at 7 o’clock ）
It was 7 o’clock when I arrived. (when时间状语从句.在7 o’clock前无介词at.)
It is three years since he came here. 自从他来这已经三年了.

（2）与主语从句的区别

（3）与there be 句型的区别.
