第一篇：What 用法小结
What 用法小结
一、what about与how about
用这两个短语放在句首的简略问句，都可以用来表示征求意见或询问情况。两者可以互换，但有时不能，what about也有别的用法和解释。例如：What about going to Harbin tomorrow? =How about going to Harbin tomorrow? What about the funding? Where are we going to get it? =How about the funding? Where are we going to get it?
注意what about有别的用法和解释。例如：What about it? =What shall we do? What about the others(Concerning the others, what is your plan or idea? 别的人怎么办？（至于别人，人有什么打算或意见？）What about it?(Tell me more precisely what you mean.)这是怎么回事？（把你的意思明确的地告诉我。）
二、what if, what of和what for
这三个短语的用法和含义各不相同。
What if表示“倘若……将会怎样？即使……又有什么关系呢？”； what of 表示“……的情况怎样？……又有什么重要性呢？； what for为何目的？为什么？。
例如：What if it rains while we are out?倘若我们外出遇上下雨，那怎么办呢？
What of it?那有什么了不起呢？（那又怎么样呢？）Well, and what of it?(It has no importance.)嗯，那又怎么样呢？（怎么，那有什么了不起？）
What for did you ask that silly question? Now he’s going to speak for another ten minutes.你干吗要问那个愚蠢的问题？这一来他又得说上十分钟。What did you do that for?
三、what作the thing that 或as much…as解。What作关系代词，其作用相当于the thing或people that，请比较：
The thing that I like most in her is her kindness.=What I like most in her is her kindness.The upstart is not what he was ten years ago.=The upstart is not the man that was ten years ago.这个暴发户已经不是十年前那个人了。
四、What作关系形容词，其作用相当于as much…as, whatever。请比较：
She will give the sick baby what care she can.=She will give the sick baby as much care as she can.Lend me what money you have on hand.五、What …is或What…are
当what引导的从句作主语时，谓语动词要根据表语的内容判断。请比较：
What I need most are two books.What I need most is only one book.六、what is＋形容词或副词比较级
常用的短语有：what is more而且；
what was worse 更糟糕的是；
what is better而且更可贵的是； what is the best of all最难能可贵的是 what is more important更重点的是；what is more disappointing更令人失望的是等等。
例如：She said it, and what is more disappointing, she did.她那样说了，而且更使人失望的是，她还那样做了。
And, what makes the matter worse, she has already taken to smoking.而且，更糟糕的是，她已经迷上吸烟了。
七、What is…like?和What does…like?
前者like是介词,答语是形容词；而后者like是动词其答语是名词。例如： What is your sister like? She is very clever.What does she like? She likes picture books.八、What is he like?和What is he? 前者指外貌和品行等,其答语用形容词； 而后考则指职业，其答语是职业名词。
例如： What was he like ten years ago? Very honest.What was he ten years ago? A teacher.九、What+名词和what+little的区别。
前者表示：“所有的都”； 而后者表示：“虽少但全部”。
请比较：She saved what little money she could out of her slim salary to help her brother go to school.她从她微薄的薪金中尽量省出一些来帮助她兄弟上学。She gave her sister what books she had.她把她所有的书都给她妹妹了。
十、what to do在句子中可作主语、宾语、表语等。例如：
What to do next has not been decided.I don’t know what to do with these used desks.十一、What one is和what one has的区别
前者指一个人的品质或特征； 而后者指一个人的财富。
请比较：I married you not for what you have but for what you are.我嫁给你不是为了你的财富，而是看上了你的人品。
十二、what with…and what with…和what by…and what by…
两者表示：“一半由于……一半由于；一方面由于……一方面由于”。例如：
What with hard work and what with taking too little care of himself, our headmaster came to leave this world at the age of fifty.一半由于工作太累，一半由于太不关心自己，所以我们的校长五十岁就去世了。
十三、whatever和no matter what区别
引导让步状语从句时，二者没有区别，但whatever可引导名词性从句也可以作限定词，而no matter what不能。
请比较：Whatever you do, you must do it well.=No matter what you do, you must do it well.Whatever you do should be done well.Whatever books you have, you should often read.Whatever you say goes.=Anything that you say goes.无论你说什么，都会照办

It用法小结
it在英语语法中属人称代词，意思是“它”，用来指人以外的一切生物和事物。它的用法不仅不简单，而且很复杂。
一、用于指人以外的一切生物、无生命的东西和事情。
一般指说话者心目中已经了解或所指的生物、无生命的东西或事情、没有性别的区分；可以是可数名词，也可以是不可数名词，在句子中既可做主语，也可以作宾语。
1．指动物和植物。如：
—Oh，that's Lucy's hat．噢，那是露茜的帽子。
—It looks like a cat！它看上去像只猫！
Where's tea grown？It's grown in the southeast of China．
什么地方种植茶？中国东南部种植茶。
2．指代一些无生命的东西。如：
Is it your watch？这是你的手表吗？
Look at the rain！It's heavy，isn't it？看这雨！雨很大，对吗？
3．代替上文提到过的整个事情。如：
Well，you mustn't play on the road．It's dangerous．哦，你不能在公路上玩。这太危险了！It was hard work，but they really enjoyed it．摘苹果是艰苦活，可他们都乐意去干（它）。
二、用于指代人。
1．指代说话者心目中不太清楚的那个人，常在打电话或敲门时用。如：
—Who was it？是谁（打来的电话）？
—Was it Susan？（打电话的）是苏珊吗？
—Yes，it was．是的，我是。（根据上下句，“it was”也可不译出来。）
再如：—Who is knocking at the door？谁在敲门？
—It's me．是我。
2．指说话者心目中的那个人。如：
—Is it your sister，Kate？（那旧照片上的 baby）是你姐姐凯特吧？
—No！不是。
—Is it your brother？是你哥哥吧？
—No！不是。
—I know—it's you！我知道了，（那）是你。
3．指代性别不详的婴幼儿或在不计较性别时，也可用it来指人。如
The child smiled when it saw its mother．这小孩一见到母亲就笑了。
I don't know who it is．我不知道他是谁。
注意：看到这样的句子（或听到这样的话）时，要想一想，不要一看到it就把它译成“它”。）
4．在回答用指示代词表示人的特殊问句时，常用it指人。如：
—Who's that？那人是谁？
—Is it Kate？是凯特吗？
—Yes，I think you're right．It's Kate．是的，我想你说对了，是凯特。
三、用于指时间、距离和自然现象等。
1．表示时间。如：
—What time is it？几点钟？
—It's ten．十点钟。
It's summer in Australia now．现在澳大利亚是夏天。
特别注意it用于表示时间时还常见于以下两个句型中：
（1）It's time（for sb．）to do sth．／It's time for sth．译为“是（某人）该干„„的时间了”、“到„„的时候了”。如：
It's time for supper／to have supper．是吃晚饭的时候了。
I think it's time for us to start the lesson now．我想现在是我们开始上课的时候了。
（2）It is ／has been ＋时间段＋since ＋一般过去时。译为“自从„„以来已过了„„（时间）”。此结构可以与另一种句型进行同义句转换。如：
It has been two weeks since we met last．＝ Two weeks has passed since we met last．自从我们上次相遇以来，两个星期过去了。
It's three years since he came here．＝It has been three years since he came here．＝He has been here for three years．他到这里已经三年了。
2．表示距离。如：
It's half an hour's walk from my home to the school．从我家到学校步行得花半小时时间。—Where's the farm，Li Lei？Is it far？李雷，农场在哪里？远吗？
—No，it's quite near．不，（距）离这很近。
3．表示自然现象。如：
Sometimes it snows and the land is all white．有时下雪，大地一片白。
It is very quiet here at the moment．眼下这儿很安静。
四、用作形式主语。
英语中常常见到某个句子以it开头，it与其后面的动词不定式短语、动名词短语、名词性从句等相呼应，以表达一个完整的意义。这是一种习惯表达法，这样的句式可避免句子显得头重脚轻。
1．It＋is／was＋形容词＋（for／of sb．）＋动词不定式短语。对于这个句型中究竟用 for还是用of，一般遵循这样的规则：如果形容词仅仅是描述事物的形容词，如：difficult，easy，hard，important，dangerous等用for；如果形容词是描述不定式行为者的性格、品质的，如：kind，good，nice，clever等则用of。如：
It is interesting to play with snow in winter．冬季里玩雪是很有趣的。
It's important for us to keep the water clean．保持水质清洁对我们来说是很重要的。It's very kind of you to say so．你这样说真是太好了。
注意：这一句式中的形容词位置也可换用名词；连系动词be也可换用其它连系动词，如feel等。如：
It's a good habit to get up early and go to bed early．早睡早起是好习惯。
It must be great fun to fly to the moon in a spaceship．乘宇宙飞船飞往月球一定很有趣。It feels strange to have a twin sister．有个孪生姐妹感觉很奇怪。
2．It ＋will be／is ／was ＋形容词＋动名词短语。如：
It's bad playing in the street．在街上玩是没好处的。
Is it any good trying again？再试一次有用吗？
3．It＋is／was＋形容词＋从句。如：
It is certain that he will come．他一定会来。
It's true that he may fall behind the other students．他真的可能落后于其他同学。
It is strange that he should say so．他居然这么说，真是奇怪。
4．It ＋is ／was ＋one's turn（duty，pleasure）＋to do sth．意为“该轮到某人做某事（做某事是某人的责任、愉悦的事）”。如：
It's your turn to be on duty tomorrow．明天轮到你值日了。
5．It takes（sb．）some time to do sth．意为“（某人）花„„时间做某事”。如
It took me a week to finish reading the book．我花了一周时间看完这本书。
6．It ＋cost／costs ＋sb．＋some money ＋to do sth．译为“某人花多少钱做某事”。如：It cost me 260 yuan to buy the new watch．我买这块新手表花了260元。
7．It seems ／seemed ＋从句。译为“看起来好像„„”，此结构可以转换成“seem ＋动词不定式”形式。如：
It seems that he is ill．＝He seems to be ill．看起来他好像病了。

② In fact________ is a hard job for the police to keep order in an important football match.A.thisB.thatC.thereD.it
答案: ① D ② D
五、用作形式宾语。
当句子的真正宾语是动词不定式、动名词或从句时，为避免句子头重脚轻，须将其放在宾语补足语之后，改用先行词it占据其原来的位置。it用作形式宾语的句型为：主语＋谓语＋it＋宾语补足语＋动词不定式／动名词／从句。该句型中宾语补足语可由形容词、名词等充当。如：
He found it not easy to learn a foreign language well．他发现学好一门外语是不容易的。We think it no good reading in bed．我们认为躺在床上看书无益处。
I think it necessary that we have the meeting．我认为开这个会是必要的。

3．指代性别不详的婴幼儿或在不计较性别时，也可用it来指人。如 The child smiled when it saw its mother．这小孩一见到母亲就笑了。I don't know who it is．我不知道他是谁。注意：看到这样的句子（或听到这样的话）时，要想一想，不要一看到it就把它译成“它”。）4．在回答用指示代词表示人的特殊问句时，常用it指人。如：
—Who's that？那人是谁？
—Is it Kate？是凯特吗？
—Yes，I think you're right．It's Kate．是的，我想你说对了，是凯特。
三、用于指时间、距离和自然现象等。1．表示时间。如：
—What time is it？几点钟？
—It's ten．十点钟。
It's summer in Australia now．现在澳大利亚是夏天。特别注意it用于表示时间时还常见于以下两个句型中：（1）It's time（for sb．）to do sth．／It's time for sth．译为“是（某人）该干„„的时间了”、“到„„的时候了”。如：
It's time for supper／to have supper．是吃晚饭的时候了。
I think it's time for us to start the lesson now．我想现在是我们开始上课的时候了。
（2）It is ／has been ＋时间段＋since ＋一般过去时。译为“自从„„以来已过了„„（时间）”。此结构可以与另一种句型进行同义句转换。如：
It has been two weeks since we met last．＝ Two weeks has passed since we met last．自从我们上次相遇以来，两个星期过去了。
It's three years since he came here．＝It has been three years since he came here．＝He has been here for three years．他到这里已经三年了。2．表示距离。如：
It's half an hour's walk from my home to the school．从我家到学校步行得花半小时时间。
—Where's the farm，Li Lei？Is it far？李雷，农场在哪里？远吗？
—No，it's quite near．不，（距）离这很近。3．表示自然现象。如：
Sometimes it snows and the land is all white．有时下雪，大地一片白。It is very quiet here at the moment．眼下这儿很安静。
四、用作形式主语。
英语中常常见到某个句子以it开头，it与其后面的动词不定式短语、动名词短语、名词性从句等相呼应，以表达一个完整的意义。这是一种习惯表达法，这样的句式可避免句子显得头重脚轻。
1．It＋is／was＋形容词＋（for／of sb．）＋动词不定式短语。对于这个句型中究竟用 for还是用of，一般遵循这样的规则：如果形容词仅仅是描述事物的形容词，如：difficult，easy，hard，important，dangerous等用for；如果形容词是描述不定式行为者的性格、品质的，如：kind，good，nice，clever等则用of。如：
It is interesting to play with snow in winter． 冬季里玩雪是很有趣的。
It's important for us to keep the water clean．保持水质清洁对我们来说是很重要的。It's very kind of you to say so．你这样说真是太好了。注意：这一句式中的形容词位置也可换用名词；连系动词be也可换用其它连系动词，如feel等。如：
It's a good habit to get up early and go to bed early．早睡早起是好习惯。
It must be great fun to fly to the moon in a spaceship．乘宇宙飞船飞往月球一定很有趣。It feels strange to have a twin sister．有个孪生姐妹感觉很奇怪。2．It ＋will be／is ／was ＋形容词＋动名词短语。如： It's bad playing in the street．在街上玩是没好处的。Is it any good trying again？再试一次有用吗？ 3．It＋is／was＋形容词＋从句。如：
It is certain that he will come．他一定会来。It's true that he may fall behind the other students．他真的可能落后于其他同学。It is strange that he should say so．他居然这么说，真是奇怪。
4．It ＋is ／was ＋one's turn（duty，pleasure）＋to do sth．意为“该轮到某人做某事（做某事是某人的责任、愉悦的事）”。如：
It's your turn to be on duty tomorrow．明天轮到你值日了。5．It takes（sb．）some time to do sth．意为“（某人）花„„时间做某事”。如 It took me a week to finish reading the book．我花了一周时间看完这本书。
6．It ＋cost／costs ＋sb．＋some money ＋to do sth．译为“某人花多少钱做某事”。如： It cost me 260 yuan to buy the new watch．我买这块新手表花了260元。7．It seems ／seemed ＋从句。译为“看起来好像„„”，此结构可以转换成“seem ＋动词不定式”形式。如：
It seems that he is ill．＝He seems to be ill．看起来他好像病了。

五、用作形式宾语。
当句子的真正宾语是动词不定式、动名词或从句时，为避免句子头重脚轻，须将其放在宾语补足语之后，改用先行词it占据其原来的位置。it用作形式宾语的句型为：主语＋谓语＋it＋宾语补足语＋动词不定式／动名词／从句。该句型中宾语补足语可由形容词、名词等充当。如：
He found it not easy to learn a foreign language well．他发现学好一门外语是不容易的。We think it no good reading in bed．我们认为躺在床上看书无益处。I think it necessary that we have the meeting．我认为开这个会是必要的。[原题再现] Don't ________that all those who get good grades in the entrance examination will prove to be most successful.A.take as granted
