高中英语强调句用法

not … until … 句型的强调句
1. 句型为:It is/ was not until + 被强调部分 + that + 其他部分
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 back that 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。
说明:1)当强调的主语指人时:用who或that,如果被强调的部分是其它成分时,必须用that,不能用which,where,when.

2)强调主语时,从句谓语动词的人称和数要与被强调的主语部分一致,被强调的主语是人称代词,宜用主格,但有时也可用宾格 :

Eg:  It is I who( 或that) am your true friend.只有我是你真正的朋友。

3)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 ….也可以用”情态动词+be”形式.如:It might be yesterday that John bought a book for Mary.
4)强调句型否定形式:It is/ was not + 被强调部分(通常是主语、宾语或状语)+ that/ who+ 其他部分;

 5)判断依据: 就是把 it is/was …that 去掉后,剩下的词仍能组成一个完整的句子。这是判断是不是强调句型的关键,完整是强调句型。 试比较:

  1. It is strange thathe didn’t come yesterday.
  2. It is you and Tomthat didn’t come yesterday.

句1去掉It is… that …后,句子结构不完整,划线部分是主语从句,it是形式上的主语,不是。

句2去掉It is … that …后,句子变为you and Tom didn’t come yesterday. 仍是一个表意完整的句子,这是强调句。

It was yesterday that he met her in the street. (=Yesterday he met her in the street. )是昨天他在街上碰见了她。(强调结构)

It is clear that she has heard of it. (= she has heard of it is clear. )显然她已听说了这件事。(主语从句)

It was on the farm ____ we worked.   A.that    B. there    C. which     D. where

答案D。该句易误作强调句型,这里where we worked 是定语从句,修饰the farm。用强调句型时即使强调地点状语,也不能用where而用that。该句如果要用it was… that强调句型的话,可改写为“It was on the farm where we worked that I got to know her.”

 

6) 如果强调时间、地点、原因或方式状语时,不可用when, where, why或how,而仍用that。

  1. Itwas not until midnight_____ theyreached the camp site.营地场址
  2. that B.when    C. while    D. as

答案A。该题强干扰项是B,考生容易因强调时间状语until midnight而误选。

  1. It was after hegot what he had desired想要____he realized it was not so important.
  2. that B. when    C. since    D. as

答案A。该句强调时间状语从句after he got what he had desired,题干意思是“得到他所梦寐以求的东西后他才意识到一切都不那么重要”。不要误选B。

7)强调双宾语时,无论是强调直接宾语还是间接宾语,根据适当情况加上介词 to 或 for 等。如:

It was a new dictionary that Tom gave to me last night. (=Tom gave me a new dictionary last night. )汤姆昨晚给我的是一本新词典。

It was a red shirt that John bought for me as a birthday present. (=John bought me a red shirt as a birthday present. )作为生日礼物约翰送我的是一件红衬衫。

 

  • 谓语动词的强调
    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.

这三种形式常用在谓语动词之前,以加强语气,它一般只能强调现在时与过去时。

E.g. I do wish I could. 我真希望我能。    He does look well. 他的确看起来气色很好。

Do sit down. 务必请坐。He did write to you last week. 上周他确实给你写了信。
Do be 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。
