It 构成的20句常用句型归纳
It 构成的20句常用句型归纳【句型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。
【例】It was about 600 years ago that the first clock with a face and an hour hand was made.【例】It was they that (who ) cleaned the classroom yesterday.【例】It was in the street that I met her father.【句型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。
【例】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.【句型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形式主语句型
“it”在英语中经常用作形式主语，尤其是在主语从句中。
形式主语用于表示主语从句，即一个句子作为主语，而“it”是这个句子的形式主语。
以下是几个使用“it”作为形式主语的常见句型：
1. It is + 形容词+ that + 主语从句
例如：It is clear that he has made a mistake.
解释：在这个句型中，“it”是形式主语，“that”后的句子是真正的主语。
2. It is + 名词+ that + 主语从句
例如：It is a fact that the earth is round.
解释：这个句型与上一个相似，但形容词被替换为名词。
3. It + 动词+ 主语从句
例如：It happened that he was late for the meeting.
解释：在这个句型中，“it”是形式主语，动词是主语从句的谓语。
4. It + be + 时间/距离+ before + 主语从句
例如：It will be two years before we meet again.
解释：这个句型用于表示在某个时间或距离之后会发生某事。
5. It is/was + 被强调部分+ that + 主语从句
例如：It was yesterday that he met his friend.
解释：这个句型用于强调某个时间或部分。

All (of us) like fruits. /Both (of them) are good at English.b.用作同位语。
作主语同位语时须注意它们的位置不同，位于行为动词之前；位于be动词之后。
They all (或both) agreed with me. /They are all (或both) very healthy.I know them all (或both).②one / it（人称代词）one 代替可数名词，表示上面所提到的那一类人或物中的一个，其复数形式带定语时用ones，不带定语时用some。
而it则用于指代上文提到的那个表示物的名词本身，既可指单数可数名词也可指不可数名词。
I don’t have a watch but I’m going to buy one（或some）.I have a bicycle. My aunt gave it to me.③no one / noneno one 只用于指人，而none 既可指人也可指物。
如果说“若干人（物）之中一个也不”，用“none of”,后接复数名词时，谓语可以用复数，也可用单数；后接不可数名词时，谓语用单数。
如：No one told me that he had gone to Shanghai.None of them have（或has）arrived yet.（不用no one）None of the money is mine.④some / any /no /every +（thing, one, body等。
）some 类用于肯定句，any类用于否定和疑问句。
I know nothing of what had happened to him.I have little rice, so I can’t lend you any.She is going to buy some new dresses.注:everyone和every one前者意思是“每个人”，与everybody同义，后面不可跟of短语，后者意思是每个人或物，后面跟of短语。
试比较：everyone in the classroom（教室里的所有的人）every one of the children（这些孩子中的每一个）every one of the books（这些书中的每一本）⑤部分否定与全部否定：当all, both, each和every(body, thing)等表示整体意义的代词与否定词连用时，一般只表示部分否定，如果表示全部否定，应该用none, no one, neither, nobody, nothing等.All of the students were not late for the class. 不是所有学生上课都迟到的。
(现代英语中常写成：Not all the students were late for the class.）None of the students were late for the class.没有一个学生上课迟到的。
3)疑问代词：用于构成特殊疑问句，其中what, which, whose兼有形容词特征，可以和名词连用。
What job do you want to find? /Whose girl is she?Which subject is your best one?所有疑问代词都可以起名词作用，在句子中担任成分。
Who told you? /Whom are you waiting for?Whose are those books?在学习疑问代词时，对以下几组词注意区别：①which和what两者均可与名词连用，就人或物提问。
但是which一般用于有一定选择范围的情况，what 用于无选择范围或究竟是什么还不清楚的情况。
Which colour do you like—green, red, yellow or brown?What colour is her dress?What writers do you like best?②which和who 两者都可作代词，它们的区别是不管选择的范围是大还是小，which一般用作指物。
Which would you like to eat –steak or fish?Who won the game –Smith or Johnson ?当有一定选择范围时，which one代替who作宾语.Which one do you like better, your mother or your father?Which of可和人称代词或指人的名词连用,如：Which of you has taken away my English book?4)连接代词who, whom, whose, which, what, whatever, whoever等，除起连接作用外，还可以在从句中担当主语，宾语，定语，表语等成分。
如：The question is who can operate the new machine.（引导表语从句——作主语）They asked whose idea this was.（引导宾语从句——作定语）When you are older, you can watch whatever programme you like.（引导宾语从句——作定语）I’ll give my ticket to whoever wants it.（这里whoever可看成“anyone who”，or“the person who”）.试完成下列高考单项选择题：1.We couldn’t eat in a restaurant because _______ of us had ______ money on us.A.all, noB.any, noC.none, anyD.no one, any2.Few pleasures can equal ______ of a cool drink on a hot day.A.someB.anyC.thatD.those3.I read about it in some book or other, does it matter _____ it was?A.whereB.whatC.howD.which4.The Parkers bought a new house, but _____ will need a lot of work before they can move in.A.theyB.itC.oneD.which5.I agree with most of what you said, but I don’t agree with ______.A.everythingB.anythingC.somethingD.nothing(答案1-----5 C C D B A )。
