二、it作形式主语

用作形式主语,代替后面真正的主语动词不定式、动名词短语、that从句或wh-从句。在这种结构中,it大多可由短语、不定式或从句来替换作主语。it的这种结构常见的句式如下:

⑴ It + be + 形容词或“a(n) + 名词”+ to do sth.。用于这一结构的名词常用的有a pleasure, a pity, a fact, a shame, an honor, a wonder, a good thing及good news等。

It is not easy to learn English well. = To learn English well is not easy. 学好英语不容易。

It is a pleasure to see you again. 很高兴又见到你。

⑵ It +be +形容词+for sb. to do sth.。在这一句式中,形容词通常是表示事物的性状或特征的形容词,常见的有difficult, hard, easy, heavy, dangerous, expensive, useful, important, possible及necessary等。

It is impossible for her to buy the car with cash. 要她用现金买那辆汽车是不可能的。

It is necessary for us to master at least a foreign language. 我们有必要至少掌握一门外语。

⑶ It +be +形容词+of sb. to do sth.。在这一句式中,形容词通常是表示人的行为或品德的形容词,常见的有honest, wise, clever, brave, foolish, kind, good, careful, stupid, silly, nice, right, wrong, polite及rude 等。

It is no use talking to him about it. 跟他谈那件事没用。

It is no good (my) taking up the matter now. (我)现在即使提起那个问题也是没有用的。

⑸ It +be +形容词+doing sth.。

It is dangerous playing with fire. 玩火是危险的。

⑹ It + 形容词+ that从句或wh-从句。

⑺It +be +及物动词的过去分词+that 从句。用于这一结构的过去分词常见的有said, told, known, considered, hoped, recorded, suggested, thought及reported等。

⑻ It +doesn’t +matter +其它成分。

⑽ It + makes + a / no difference + wh-从句。

It makes a difference which you choose. 你选择哪一个,事关重大。

It makes no difference whether he goes or not. 不管他去还是不去都没有影响。

it可以用于强调句中

在强调结构中,it本身无词义,是无人称主语,其作用是改变句子结构,使某一部分得到强调.1.基本结构:It is / was +被强调部分+that...(注:被强调部分是人时,可以用who代替that.)特点:A)该句型可以用来强调除谓语以外的所有成分.谓语的强调要用do的适当形式.B)被强调代词的格要与原句保持一致,谓语动词与原句一致.

eg: I met Lucy in the street yesterday.

It was Lucy that I met in the street yesterday.

It was in the street that I met Lucy yesterday.

It was yesterday that I met Lucy in the street.

I did meet Lucy in the street yesterday.

eg: I am going to have an exam tomorrow.

It is I who/that am going to have an exam tomorrow.

eg: I have a lot of work to do .

I do have a lot of work to do.

eg: We gave him a book yesterday.

It was him to whom we gave a book yesterday.

It was a book that we gave (to) him yesterday.

2. not until部分结构中若强调until后的成分,则要把not until 一起提前,

结构为:It is not until... that...

eg: He didn't finish his homework until 12pm.

It was not until 12pm that he finished his homework.

eg: She didn't watch TV until she finished the book.

It was not until she finished the book that she watched TV.

3.怎样对被强调部分提问.

eg: She visisted Tom last week.

It was Tom that she visited last week.

Was it Tom that she visited last week?

Who was it that she visited last week.

4.强调句和it作形式主语的区别.

一个句子如果去掉It is/was....that后,句子仍是完整的,该句就是强调语.

eg:It is certain that Tom is taller than Jim.(it作形式主语)去掉后句子不正确.It is Tom that is taller than Jim.(强调句)

去掉后,句子为:Tom is taller than Jim.结构仍是完整的.

it在强调句中的使用

it在强调句中的使用 先看看这道题: __________ these boys that played tricks on their teachers. A. They were B. It were C. There were D. It was 【分析】此题应D。这是一个强调句型,其基本结构为: It is+被强调部分+that(who)+其他 该句型应注意以下几点: 1.不管被强调部分是单数还是复数,其前一律用It is / It was,而不能用They are / There were之类的。 2.被强调部分是指人时,被强调部分后可用that / who,被强调部分指物时,被强调部分后只能用that。 3.被强调部分是指时间或地点时,被强调部分后通常用that,一般不用when,where之类的。 It is I who am right. 是我对。 It was you that were wrong. 是你错了。 It was in the Japan that he died. 他是死于日本。 It was yesterday that he got married. 他是昨天结婚的。 It was a computer that he bought last week. 他上个星期买的是一台电脑。 Where was it that she lived? 她是住在什么地方? When was it that he left for Japan? 他是什么时候离开去日本的? Who is it that teaches you English? 是谁教你们英语? 凸显文章亮点常用方法 写作时,如果仅局限在把内容交代清楚的水准上,只选用一些普通的、直截了当的词,或一律使用简单句平铺直叙,那么,这样写出来的文章就会像一碗白开水,呆板、单调,没有可读性。要使文章耐人寻味,有深度,同学们就应尝试使用一引起高级词汇或句型,以凸显文章的亮点,使文章增添文采,给读者(尤其是阅卷留下深刻印象)。具体说来,同学们可尝试以下方法: 一、灵活改变句子开头 在通常情况下,英语句子的排列方式为“主语+谓语+宾语”,即主语位于句子开头。但若根据情况适当改变句子的开头方式,比如使用倒状语或以状语开头等,会使文章增强表现力。如:

用法大全英语强调句及it强调句、It的用法、省略和插入语 一、强调句 (一)强调句句型 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 yesterday that 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 yesterday that 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 was I that (who) met Li Ming at the railway station yesterday. 强调宾语:It was Li Ming that I met at the railway station yesterday. 强调地点状语:It was at the railway station that I met Li Ming yesterday. 强调时间状语:It was yesterday that 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 其它部分+ that + 被强调部分It is/ was not until + 、句型为:1 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。(三)谓语动词的强调 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. 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。 二、It的用法 (一)作人称代词 1、it代替前面(或后面)的单数名词或分句等所表示的事物。 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) 2、代替有生命但不能或不必分阴阳性的东西(包括婴儿)。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. (it代替前面的tree)
