英语中it的用法
it 在英语中的意思较多，用法较广，现总结如下。
一、it作句子的真正主语
1．it 指前面已经提到过的人或事物，有时指心目中的或成为问题的人或事物，作真正主语。
例如：
What’s this? －It is a sheep? 这是什么？？这是一只绵羊。
Who is it? －It’s me (I). 谁？？是我。
It’s the wind shaking the window. 是风刮得窗户响。
2．it指时间、季节。一般用在无人称动词的主语。
例如：

It’s time for the meeting. Let’s go. 开会的时间到了，我们走吧。
What day is today? －It’s Saturday. 今天星期几？？今天星期六。
What’s the date today? －It is October 1st.
今天是几号？？今天是十月一日。
What season is it? －It is summer. 现在是什么季节？？是夏季。
3．it 指气候。一般作无人称动词的主语。
例如：
Is it cold in this room? －No, it isn’t. 屋里冷吗？？不冷。
What’s the weather like today? －It is fine.
今天天气怎么样？？是晴天。
It often rains in summer and it often snows in winter in this city.

4．it指距离、情况等。一般用作无人称动词的主语。

从我家到学校有五公里。
It is very near from this factory to that one.
从这个工厂到那个工厂非常近。
It is a long way to the sea. 离海很远。
Is it well with you? 你身体好吗？
二、it作形式主语
动词不定式、动名词短语起、从句在句子中起主语作用，而这一部分用词较多时，可以用it作为形式主语，放在句首代表其后所说的事实上的、真正的主语，而把真正的主语放在后面。
1．It +谓语＋动词不定式。It 作形式主语，动词不定式作真正的主语。
例如：
It is difficult to climb a mountain. 爬山是很艰难的。
It’s a good habit to do morning exercises.作早操是个好习惯。
It’s important to do proper memory work in the study of a foreign language. 在学习外语时适当地做一些有助于记忆的练习是很重要的。
It is right to do so. 这样做是对的。
2．It＋谓语＋动名词短语。It 作形式主语，动名词短语作真正的主语。
例如：
It is dangerous playing with fire. 玩火是危险的。
It is no use learning without thinking. 学而不思则罔。
It’s useless arguing with a silly boy. 和笨孩子争论是没有用的。
3．It ＋谓语＋名词性从句。It 作形式主语，以that 引导的名词性从句是真正的主语。
例如：
It is a pity that you didn’t see such a good film.
你没看这么好的电影，真可惜。
It is certain that we shall succeed. 我们一定会成功。
It is strange that nobody knows where he lives.
真奇怪，谁也不知道他住在哪里。
（It is strange that…后面可用虚拟语气。
如：It is strange that he should have made such a mistake.
他居然犯了这样一个错误，真奇怪。
It is strange that nobody should know where he lives.
居然没有人知道他住在哪里，真奇怪。）
It is said that the plane will take off at ten tomorrow morning.
据说飞机明天上午十点起飞。
三、it作形式宾语
it 作形式宾语，代表其后所说的真正的宾语。真正的宾语是以that 引导的名词性从句或不定式短语。例如：
I consider it wrong that you Chinese students learn English without comparing it with your own language.
我认为你们中国学生学习英语，不和你们自己的语言比较是不对的。
I find it not so difficult to learn a foreign language.
我发现学习一门外语不那么困难。
I remember I made it clear to you that I was not coming.
我记得向你明确表示过我不来。
They want to make it clear to the public that they are doing an important and
necessary job.
他们要向公众表明，他们在做一件重要而又必要的工作。
四、it 用于强调结构
在表示强调的结构中，it 可用作先行代词，这种结构的句型如下：It +is/was +被强调的部分＋that +其他部分。如果强调的部分是人，可用who, whom 代替that. 例如：
Professor Wang teaches us English every Monday afternoon.
王教授每星期一下午教我们英语。
强调主语：It is Professor Wang who teaches us English every Monday afternoon.
强调间接宾语：It is us whom Prof. Wang teaches English every Monday afternoon. 强调直接宾语：It is English that Prof. Wang teaches us every Monday afternoon.
强调状语：It is every Monday afternoon that Prof. Wang teaches us English.
It was here that I first met him. 这就是我初次与他见面的地方。
（强调状语）
It is the people who are realy powerful.
翻译练习

2)从这儿到你们学校远吗？？不远，大约一公里。

反意疑问句
反意疑问句相当于“对不对？”“好不好？”“行不行？”，用yes或no 回答。由两部分组成，前一部分是陈述句，后一部分是附加疑问短语，中间用逗号隔开，所以反意疑问句又叫附加疑问句。通常的形式是：肯定的陈述句＋否定的附加疑问，或否定的陈述句＋肯定的附加疑问。
如：
He studies English, doesn’t he?
He doesn’t study English, does he?
They are from America, aren’t they?
They are not from America, are they?
反意疑问句的主要形式：
1．如果主句是be或其他助动词（如can, shall, will 等），其反意疑问句用同一助动词。
如：
We are late, aren’t we?
Y ou haven’t met my wife, have you?
He can drive a car, can’t he?
They used to have difficulty in just making ends meet, didn’t (usedn’t) they?
Y ou’d better eat with knives and forks, hadn’t you?
2．如果主语带有seldom, hardly, never, rarely, few, little等否定词或半否定词时，因为主句本身具有否定意义，附加疑问部分的动词用肯定式，
如：
We seldom go to the cinema, do we?
Sue almost never worked, did she?
3．如果主句部分是“I am…”结构，由于”am not” 没有相应的缩略形式，附加疑问部分一般用aren’t I 代替。
如：
I am your friend, aren’t I?
I’m late, aren’t I?
I am a student, aren’t I?
在祈使句中的附加疑问部分一般用will you, won’t you.
4. 在祈使句中的附加疑问部分一般用will you, won’t you.
如：
Sit down, will you?
Have some tea, won’t you?
Open the window, won’t you?
这种句子可以理解为: Will you do something?
如:Will you open the window?
注意：否定的祈使句之后，只能用will.
如：
Don’t forget, will you?
Don’t make so much noise, will you?
5．以Let’s… 开头的祈使句，肯定的用shall we? 否定的用all right? 或OK?, 如：
Let’s go back to our seats, shall we?
L et’s not have hot food this time, OK? (all right?)
这种句子可以理解为：Shall we (do something?),
如:Shall we go back to our seats.这样有助于理解和记忆。
注意：Let’s 与Let us 的区别：Let’s包括听话人在内，应用shall we, 而Let us 不包括听话人在内，表示“请你让我们…”，要用will you.
如：
Let’s watch the news on TV, shall we? （表示建议）
Let us watch the news on TV, will you? （表示请求）
6．主句是I suppose, I think, I believe等时，附加疑问部分则往往与that 从句中的主语和谓语动词保持对应关系，但要注意否定的转移。
如：
I suppose that you know the meaning of the word, don’t you?
（这句话明显是要问“你是不是知道？”而不是问“我是不是这样认为？”）
I don’t think that you have read the book, have you?
7．当主句的动词have 表示“拥有”时，附加疑问既可用have, 也可用do,
如：
Y ou have a color TV set, haven’t you/don’t you?
当主句的have不表示“拥有”而表示其他意思时，附加疑问要用do,
如：
Y ou had a cold yesterday, didn’t you?
The y don’t have coffee with breakfast, do they?
8.There be句型的反意疑问句，用there 作主语。
如：
There is something wrong, isn’t there?
There won’t be any trouble, will there? 不会有任何麻烦，是吗？
9.陈述部分的主语是everyone, someone, anyone, no one, nobody等不定代词时，其疑问部分的主语可用he, 也可用they.
如：
Everyone knows it, doesn’t he/don’t they?
英语反意疑问句的回答有点和汉语的相反。但一定要记住：只要回答是肯定的，都用yes，只要回答是否定的，都用no。这在主句是否定句的时候要特别注意。例如：
Mr. Jones can’t speak French, can he? ？No, he can’t.
琼斯先生不会讲法语，对吗？？对，他不会讲法语。
Mr. Jones can’t speak French, can he? ？Y es, he can.
琼斯先生不会讲法语，对吗？？不，他会讲法语。
This is not a door, is it? －Y es, it is. It is an iron door.
这不是门，对吗？？不，这是门。是扇铁门。

高中英语语法知识之It的用法总结
高考英语语法知识之It 的用法总结 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，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 they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was 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 ... 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。 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. 6. It is suggested ( ordered ... ) that ... 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. It is a pity that he is ill. 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 / that 替换．常译为＂这是某人第几次做某事了＂。 It is the first time I have been here. = This is the first time I have been here. 10 It is the +形容词最高级+ 名词+ that + ….. 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 / that 替换．常译为＂这是某人做过的最…的事情＂。 This is the best film that I have ever seen .
