(2)引词IT用于强调结构中

①英语中常用的强调结构是：“It is (was)+被强调的部分(主语、宾语或状语)+ who(that)”.一般说来,被强调部分指人时用who,指物时用that(但that亦可指人).注意：强调结构在强调状语时,只可用that从句,不可用which.

For example: John wore his best suit to the dance last night.(约翰昨晚他穿着他最好的一套衣服去参加舞会)

It was John who (that) wore his best suit to the dance last night.

It was his best suit (that) John wore to the dance last night.

It was last night (that) John wore his best suit to the dance.

It was to the dance that John wore his best suit last night.

②强调结构也可强调短语和从句(包括because,only when,who,whom,whose,that,which等引导的从句).

For example:

I suspected it was on her orders that you were bringing him here.(我怀疑你是遵照她的吩咐要把他带到这儿来的)

It was because I wanted to buy a dictionary that I went to town yesterday. (我昨天是由于想买一本字典而进城的.)

It is only when you nearly lose someone that you become fully conscious of how much you value them(只有你差一点失去某一个人时,你才会充分意识到你是多么珍视他们.)

It must be your mother who (whom, that) you are thinking of.(你在想的一定是你的母亲.)

It was your brother to whom I offered a dollar for his knife yesterday.(我昨天给了你兄弟1元钱买他的小刀.)

It is Uncle Bill whose address I lost.(比尔叔叔的地址我丢了.)

It deserves attention that it is especially the verb to do which is often found in the active voice.(应该注意, 特别是行为动词常用在主动语态中.)

③表语与宾语补语偶尔也可为被强调的部分.但通常情况下,表语一般不可用作被强调的部分.

For example:

It was a doctor that he eventually became.(他最后成了一个医生)

It’s dark green that we’ve painted the kitchen.(我们把厨房漆成了深绿色)

④强调结构的时态一般应该一致.但也有例外的例子.

For example:

It is not I who am angry.(发怒的不是我.)

I was my two sisters who knew her best(是我的两个姐妹最了解他.)

I will not be you who will have to take the blame for this.(对此受责难的将不是你.)

For exceptional example:

It is Miss Williams who enjoyed reading novels as a pastime. (是威廉姆斯小姐以读小说来消遣.)

It is these very novels that Miss Williams enjoyed reading as a pastime.(威廉姆斯小姐作为消遣所读的小说就是这些.)

⑤强调结构不但可以用于独立句中,也可以用在从句之中.

For example:

It deserves attention that it is especially the verb to do which is often found in the active voice.(应该注意, 特别是行为动词常用在主动语态中.)

I suspected it was on her orders that you were bringing him here.(我怀疑你是遵照她的吩咐要把他带到这儿来的)

He told me that it was liberation that brought about a complete change in his life. (他告诉我是解放才使他的生活有了翻天覆地的变化.)

⑥强调结构中的that 与who在非正式文体中可以省略.有时还可以省去句首的It is (was).

For example:

I suspected it was on her orders you were bringing him here.(我怀疑你是遵照她的吩咐要把他带到这儿来的)

A good, honest trade you are learning, Sir Peter! (彼得爵士,你学得是一种很好而诚实的一行啊!)

⑦强调结构中的被强调部分有时可放在句首.

For example:

Now was it that his life was done, and the fate which he could not escape was upon him.(就在这时,他的生命完结了,他所逃脱不了的命运降临了.)

⑧It is(was)之后可有一个以上的被强调部分.

For example:

it用法总结 第7篇

◆典型陷阱题分析◆

1.Everyone knows that _______ is dangerous to play with fire, but _______ is difficult is to prevent children from playing with fire.A.it, it

C.it, what B.what, what D.what, it

【陷阱】很容易误选B，认为两空均考查形式主语。

【分析】最佳答案是D，第一空填形式主语，真正的主语是其后的不定式 to play with fire。第二空填 what，what is difficult 是主语从句，注意 what is difficult 后的谓语动词 is。请做以下类似试题：

(1)I know ______ is important to know my own limitations, but _______ is difficult is to help others to know their own limitations.A.it, it

C.it, what B.what, what D.what, it

(2)Yes, ______ is difficult to find a job nowadays, but _____ is more difficult is try to find such a job with a high salary but little things to do.A.it, it

C.it, what B.what, what D.what, it

2.I dislike _______ when others laugh at me in public or think poorly of me behind.A.that

C.it

【陷阱】几个干扰项均有可能误选。

【分析】最佳答案是C，因为在通常情况下，like 是及物动词，其后应有宾语(句中 it 即为其宾语)。句中的 when 从句不是宾语从句，而是时间状语从句，其中的 when 的意思是“当……的时候”。其实，也有的词典将 I don’t like it when(if)… 作为一个句型来处理。能这样用的动词不多，主要的有enjoy, like, dislike, love, hate, prefer, appreciate等表示喜好的动词。

She won’t like it if you arrive late.她不喜欢你迟到。

He hates it when people use his bike.他讨厌别人用他的自行车。B.those D.them

请做以下类似试题(答案均选 it)：

(1)I hate _______ if people say such things in public.A.thatB.those C.it

D.them

(2)I’d prefer _______ if I didn’t have to get up early on Sundays.A.that C.it

B.such D.which

(3)I would appreciate _______ very much if you could give me some suggestions.A.this C.it

B.that D.you

3.I’ve no idea.I just pretended nobody was at home, so I didn’t ask who _______ was.A.he C.she

【陷阱】容易误选A或C。

【分析】最佳答案是D。it 用以指身份不明的人。若指身份明确的人，则不宜用it。比较：

(1)Mr Smith is at the door._______ wants to see you.(2)Someone is at the door.________ must be Mr Smith.A.HeB.It C.This

D.That B.that D.it

第(1)题选A，因为来者身份明确；第(2)选B，因为来者身份不明确。4.“Excuse me, I want to have my watch fixed, but I can’t find a repair shop.” “I know ________ nearby.Come on, I’ll show you.”

A.one C.some

【陷阱】容易误选B。

【分析】最佳答案是A。it 和 one 的区别可简单地概括为：it = the + 名词，one = a + 名词。如：

I haven’t got any pens, and I want to borrow one.我没有钢笔，我想借一支。(one = a pen)I have two pens, and I can lend one to you.我有两本支钢笔，我可以借一支。(one = a pen)

B.itD.that

I have a pen, and I can lend it to you.我有一本钢笔，我可以把它借给你。(it = the pen)在上面一题中，one 相当于 one 相当于 a repair shop。请做下面一题（答案选A）： There is only one English-Chinese dictionary in that book-shop.I wonder if you still want to buy _______.A.it C.another

B.oneD.any

5.Will you see to _______ that my children are taken good care of while I am away? A.it

C.yourselfD.them

【陷阱】几个干扰项均有可能误选。

【分析】最佳答案是A。it 为形式宾语，真正的宾语是空格后that引导的宾语从句。see to 意为“负责”、“注意”，其中的 to 为介词，不宜直接跟that引导的宾语从句，遇此情况可借助代词 it。请做下面两题，答案也是选 it：

(1)I’ll see to _______ that all these letters will be sent to the post before twelve.A.it C.which

B.me D.them B.me

(2)Will you see to _______ that the luggage is brought back as soon as possible? A.me C.it

B.yourself D.them

类似以上 see to 用法的短语还有 depend on, answer for 等。如下面两题答案也选 it：(1)You may depend on _______ that he will turn up in time.A.it C.which

B.me D.them

(2)I can’t answer for ________ that the boy is honest.A.it C.which

It的用法与表达 第8篇

1 作人称代词, 指代事物、动物、婴儿或未知的人

例如以下几句。

(1) Look at the baby, isn`t it lovely? (指代婴儿)

(2) Who is knocking at the door?

It`s me. (指代不明身份或性别的人, 一般不必译出)

(3) The ant is not gathering this food for itself alone.It has two stomachs in its body. (指代前面出现的事物)

2 作非人称代词, 表示天气、时间、距离、自然现象、环境等

例如以下几句。

(1) It is very cold today. (指代天气)

(2) It is seven o`clock.Mrs Tuner goes into the kitchen. (指代时间)

(3) It is twenty mils to the zoo. (指代距离)

(4) It is very quiet here. (指代环境)

(5) It was winter.It was ten degree below zero. (指代自然现象)

3 作关系代词

3.1 代替不定式, 作形式主语或形式宾语

在这种结构中, 被代替的成分要置于句末, 这样的句式可避免句子显得头重脚轻。例如以下几句。

(1) It is of great help to master a foreign language.

(2) It took me a week to rewrite the paper.

(3) I consider it advisable to tell her beforehand.

(4) We find it quite necessary to make some changes.

3.2 代替动名词

例如以下几句。

(1) It`s dangerous sleeping out in the woods at night.

(2) I find it a waster spending so much money drinking and eating.

(3) It is worthwhile making another try.

3.3 代替名词性从句

该结构中的名词性从句可用that, what, when等连接代词或连接副词引导。例如以下几句。

(1) It is obvious that metals in common use are very important in our life.

(2) It happened that she was not at home when I called.

(3) It is not known when caused the incident.

(4) It is a mystery when they got married.

4 使用“It is/was+被强调部分+that/who+其它”的形式构成强调句型

当it构成强调句型时, 既无指代关系也无实义, 去掉句型中“It is/wasthat/who”三个词后, 剩余的词仍能单独组成一个完整的句子, 此外翻译时要突出句子中被强调成分。

例如以下几句。

I met Bob in your room yesterday.→

(1) It was yesterday that I met Bob in your room. (强调时间状语)

我就是昨天在你的房间遇见鲍勃的。

(2) It was in your room that I met Bob yesterday. (强调地点状语)

我就是在你的房间昨天遇见鲍勃的。

(3) It was Bob that I met in your room yesterday. (强调宾语)

昨天我在你房间遇见的就是鲍勃。

(4) It was I who met Bob in your room yesterday. (强调主语)

昨天在你房间遇见鲍勃的就是我。

5 使用it构成虚拟句型

考虑到主句中形容词的差异, that后面引导的从句中要用虚拟语气 (should+动词原形) , should可以省去, 这类形容词包括:important、necessary、right、strange、natural等等。例如以下几句。

(1) It is important that we (should) learn English well.

(2) It is necessary that we (should) remember these words.

此外主句中使用的过去分词若表示请求、建议、命令等词时, that后面引导的从句也要用虚拟语气 (should+动词原形) , should可以省, 常译为“据建议、有命令”等等, 这类过去分词包括:s u g g e s t e d、ordered、demanded、insisted、commanded等等, 例如以下几句。

(1) It is suggested that the meeting (should) be put off.

(2) It was ordered that we (should) arrive there in three hours.

6 用it组成的惯用语

It同动词组合可以组成惯用词组, 这种情况下, it的用法无明确指代关系, 也无明确含义。例如以下几句。

(1) Take it easy.

(2) We had a nice time of it.我们玩得很好。

(3) Win or lose, we`ll stick it out (坚持到底) .

(4) Go it (加油) !We`ll back you up.

再如:call it a day (今天就干到这里, 到此为止) 。

make it (做到, 办成) 。

go it alone (独自干) 。

rough it (生活困顿, 艰难地生活) 。

hit it (猜对, 说中) 。

beat it (走开, 滚开) 。

come it (达到目的, 成功地做) 。

brave it out (拼着干到底) 。

face it out (把坚持到底, 挺到底) 。

foot/walk it (步行) 。

just for the hell of it (只是为了好玩) 。

as luck would have it (碰巧, 不凑巧, 倒霉) 。

take it out of somebody. (拿出气) 等等。
