你好！it的句型很多的。

1 It is + 被强调部分 + that 　

该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，that可以由who换用。如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。

It was about 600 years ago that the first clock with a face and an hour hand was made

It was they that (who ) cleaned the classroom yesterday

It was in the street that I met her father

2 It is not until + 被强调部分 + that

该句型也是强调句型。主要用于强凋时间状语，译成汉语”直到．．．才．．．”，可以说是 not until 的强调形式。

It was not until she took off her dark glasses that I realized she was a famous film star

= Not until she took off her dark glasses did I realize she was a famous film star

= I didn’t realize she was a famous film star until she took off her dark glasses

3 It is clear ( obvious, true, possible, certain) that

该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为”清楚（显然，真的，肯定．．．）”　是主语从句最常见的一种结构。

It is very clear that he’s round and tall like a tree

= That he’s round and tall like a tree is very clear

4 It is important ( necessary, right, strange, natural) that

该句型和上一个同属一个句型。由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。建议记住该句型中的形容词。

It is important that we (should) learn English well

It is necessary that he (should) remember these words

5 It is said (reported, learned) that

该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为”据说（据报道，据悉．．．）”。

It is said that he has come to Beijing

It is reported that another earth satellite has been put into orbit

6 It is suggested ( ordered ) that

该句型和上一个同属一个句型。主句中的过去分词是表示请求，建议，命令等词时，that　后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为”据建议；有命令．．．）

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

It was ordered that we ( should ) arrive there in two hours

7 It is a pity ( a shame ) that

该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为”竟然”。没有这种意义时，则不用虚拟语气。

It is a pity that such a thing ( should ) happen in your class

这种事竟然发生在你们班上，真是遗憾！

It is a pity that he is ill 他生病了，真遗憾！

8 It is time ( about time ,high time ) that

该句型中that 后的从句应该用虚拟语气，值得注意的是① 常用过去时态表示虚拟．② 有时也用should + 动词原形，should 不能省。常译为”是（正是）．．．的时侯．．．”。

It is time that children should go to bed

= It is time that children went to bed

9 It is the first ( second ) time that

该句型要和上一个句型区别开来。该句型中的 that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中 that 可以省去；it有时用 this 替换．常译为”是一（二）．．．次．．．”。

It is the first time I have been here

= This is the first time I have been here

10 It is since

该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。

It is ( has been ) 5 years since his father died

11 It is when

该句型中的 when 引导的是一个时间状语从句，主句中的 it 指时间，表语由具体的时间充当。常译为”当．．．的时候，是．．．”。

It was 5 o’clock when he came here

12 It be before

该句型主句中的 it 指时间, 主句中的时态常是将来一般时或过去时两种时态．主句中的表语多是long, not long , 3 days , 2 weeks 等表示时间段的词或短语。常译为”．．．之后．．．”。

It was 3 days before he went to Beijing

It will be not long before he finishes his job

13 It happens (seems, looks, appears ) that

该句型中it是形式主语，that 引导的是主语从句，主句中的happen , seem等词是不及物动词．

It happened ( so happened ) that he met his teacher in the street 碰巧．．

It seems that he will be back in a few days 看来．．．

14 It takes sb to do sth

该句型中的不定式是真正的主语，it是形式主语，句型中的直接宾语是时间。常译为”做．．．要花费某人．．．”。

It took thousands of people many years to build the Great Wall

15 It is no good (use ) doing sth

该句型中的真正主语是动名词短语，主句中的表语可以是no good , ( not any good ) , no use , ( not any use )。

It is no good learning English without speaking English

16 It doesn’t matter whether ( if )

该句型中whether(if) 引导的从句是真正主语，该句型常译为　”不论（是否）．．．没关系．．．。

It doesn’t matter if they are old

17 It is kind ( of sb ) to do sth

该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由 of引起，主句中的形容词必须是能表示逻辑主语特征的形容词。常见的有： bad , brave , careless, clever , cruel , foolish , good （好心的）, honest , horrible , kind , lazy , modest , naughty , nice（有教养的）, polite, rude , silly , stupid , wise , wrong（错误的）等。 这个句型可以改写为：sb is kind to do sth

It is kind of you to say so

= You are kind to say so

18 It is necessary ( for sb ) to do sth

该句型与上一个同属一个句型。如果不定式的逻辑主语是由for引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。常见的形容词有：① important, necessary, natural ② easy , safe , common , normal , hard , difficult , dangerous , unusual, rare , impossible , pleasant等。

在①中的形容词作表语可以用从句改写， 如：

It is important for her to come to the party

= It is important that she (should ) come to the party

19 It looks ( seems ) as if

该句型中it无意义。 as if 引导一个状语从句。常译为，”看起来好象．．．”如果与事实不相符合，则用虚拟语气．

It looks as if he is ill（真的病了）　

It looks as if he were ill （没有生病）

It seemed as if he were dying

20 We think it important to learn a foreign language

该句型中的it 作形式宾语。为了记忆方便我们可称该句型为"6123结构"。

6指主句中常用的动词：think, believe, make, find, consider, feel；

1指的是形式宾语it；

2指的是宾补的两种形式：形容词或名词；

3指的是真正宾语的三种形式：不定式短语，动名词短语或that引导的宾语从句。

We think it our duty to clean our classroom every day

He felt it important learning English well

They found it difficult that they would finish their work in two days

It's= it is

it用来指代后面出现的真正主语，这句话的完整形式是it takes all sorts to make a world，也就是it作形式主语，指代后面的to make a world。

1、读音：英 [ɪt teɪks ɔːl sɔːts tu meɪk ə wɜːld]  美 [ɪt teɪks ɔːl sɔːrts tu meɪk ə wɜːrld] 

2、释义：万千事物，形成世界。

3、例句：It takes all sorts to make a world 一种米养百种人。

近义词：Nothing is too strange

1、读音：英 [ˈnʌθɪŋ ɪz tuː streɪndʒ]  美 [ˈnʌθɪŋ ɪz tuː streɪndʒ] 

2、释义：无奇不有。

3、语法：strange作“奇怪的”解时，可用作定语或表语，比较级是stranger，最高级是strangest，作“陌生的”解时，常用作表语，没有比较级和最高级。

4、例句：I get the scholarship, and nothing is too strange 如果我拿到这个奖学金，无奇不有啊。
