【解析】考点：it做形式主语（特殊句式）关键词：It cost（★It 不⽤不给分，cost写成co sted扣0.5分）结构部分：It costsomebody how much money to do something 其它部分：me

⼆、考点分析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 is your efforts, not your intelligence, __________(决定) your success. (determine )

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

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，believed....) 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，no wonder ... ) 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！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. This /It’s the first/second/third… time+现在完成时的句⼦It was the first second/third… time+过去完成时的句⼦

It’s the first time that I have visited（我拜访）the city.(visit)

It was the first time that you had knocked at the door of the teacher 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.

It is / has been two years 20. since he went abroad（⾃从他出国）.（go）

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…＂。Itwas 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 goodlearning 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 dosth.

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：①important, 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：

不定代词it的用法

不定代词it的用法

不定代词it的用法

一、不定代词it的基本用法

在英语中，不定代词it充当性别不明、指代某个特定事物或概念等的角色。它是一个非常常用且灵活的代词，能够承担多种种类和功能。在下面的段落中，我将会详细介绍it作为不定代词的几种常见用法。

1. 作为形式主语或形式宾语

在很多情况下，人们使用it作为形式主语或形式宾语来引导句子。这是因为句子的真正主语或宾语可能是一个复杂的短语或从句，而使用it可以把这个复杂结构移到句子后面而不影响主谓结构。

例如：

- It is important to have a healthy diet.（拥有健康饮食习惯很重要。）

- I find it difficult to understand this concept.（我发现理解这个概念很困难。）

2. 作为反身代词

当需要表示某人自己的行动时，人们通常会使用反身代词来强调动作涉及到了自己。在没有特指具体人物时，可以使用it作为反身代词。

例如：

- I really enjoyed the concert last night. It was a great experience!（我昨晚非常享受这场音乐会。它是一次很棒的体验！）

3. 引导形式主语从句或形式宾语从句

在某些情况下，it作为形式主语从句或形式宾语从句的引导词，用来替代真正的主语或宾语，以使整个句子结构清晰明了。 例如：

- It is believed that exercise can improve mental health.（人们认为运动可以改善心理健康。）

- I find it hard to believe that she won the lottery.（我发现难以相信她中了彩票。）

二、不定代词it的特殊用法

除了上述基本用法外，不定代词it还有一些特殊的使用方式。在接下来的几个段落中，我将逐一介绍这些特殊用法。

二、.非人称代词.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等：

It is a lovely day, isn’t it? // It was nearly midnight when she came back.

It is April First today. // It is some 3000 kilometers from A to B.

It is three dollars. // Today it is 30 degrees centigrade.
