（完整版）It的用法总结It的用法总结在英语中,it有许多不同的用法,它既可以用作代词(如人称代词、非人称代词)，也可以用作引导词（作形式主语或形式宾语），还可以用来构成强调句型。

.it用作代词(1) 用作人称代词在句子中作主语或宾语；指前面已经提到过的事物、动物或人，且it指特定的事物；如果指前文中提到的事物中的任何一个，用one。

one可以与any, each, every, not等连用，但one 不可代替不可数名词。

—where’s your car?—it’s in the garage. 你的汽车在哪儿呢？在车库里。

(指代物品your car)did you hit it? 你打中了吗？ (指代事件)the baby cried when it was hungry.这婴儿饿时就哭。

（指代婴儿，尤指性别不详或无所谓时）—who is that?—it’s me. 是谁？我。

(指一定情景中所确定的人或事物，此时相当于指示代词，代指this和that,有时也指人)—what’s this?—it’s a box. 这是什么？一只箱子。

(2) 作非人称代词表示天气、日期、时间、温度、距离、价值、路程、度量、自然现象与环境等。

也可模糊地指一般情形或上文的部分或整个意思。

译成汉语时，it通常不一定译出来。

it’s a long time since they left. 他们走后很久了。

it’s two miles to the beach.离海滨有两英里远。

that’s just it—i can’t work when you’re making so much noise.原因就在这里——你弄出这么大的声音，我工作不了。

另外，需要注意两点：（1）“it’s time…”后面可以接不定式和介词短语表示“是做……的时候了”。

如：it’s time for supper. it’s time to have supper.(2) “it’s time…”后面还可以接一个从句，但是从句中的谓语动词一定要用过去式即虚拟语气，如：it’s time we had lunch.是我们吃饭的时候了。

It的用法It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。

其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。

一、要点点拔1．代替上文中提到过的人或事物。

指代人时，一般用于小孩或身份不十分明朗的人。

1) －Who is the baby? －It‘s my teacher’s son．2) －Who is that gentleman?－It's my friend Tom．He(不可用It) wants to see you．2．用于表达天气、环境、时间、距离、季节等。

例如：1) It’s half an hour’s walk from here to our school．2) It‘s nice and warm here．3) But it's two o'clock now, and it's time for us to go to school．3．用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。

1).It 替代真正的主语——动词不定式短语.It is easier to say than to do .It is a good act to help the others.2).it 替代真正的主语——动名词短语,以动名词短语做主语的句子，主要在以no good, no use, no harm, dangerous, foolish 等词作表语的句中.It’s no harm drinking running water in that area。

It’s foolish talking like that.3).it 替代从句作主语，用从句做主语的带it 的句子很多,常见的有下面几类：① It is a pity (a shame ,a fact ,a wonder ,a good thing,etc. )that…It is a shame that he didn’t pass the exam.② It is strange ( surprising,obvious ,true, good,possible,clear,etc. ) that… 。

it的用法总结it 的考点：1.为避免重复，it可用来代替前面说过的短语或句子。

如：I tried to persuade my father to give up smoking, but found it impossible. (it=to persuade my father to give up smoking)2.It/This/That+be+the first(second, third...) time+that这个句型表示截止到说话时为止的某人的一种经历，关键是注意time前有序数词，主句是一般现在时is时，从句要用现在完成时；如果主句用一般过去时was 时，则从句须相应地用过去完成时。

如：This is the first time(that) these Europeans have visited the Great Wall.It was the fifth time(that) I had paid a friendly visit to America.3.强调句：It's/was+被强调成分+that/who+其他成分原句：I told Jim the news in our office yesterday.【注】强调句与主语从句虽然在形式上很相似，即都含有it is(was)...that。

但，区别在于：强调句去掉itis(was)…that之后，句子结构仍然完整，而主语从句却不能这样。

如：(It is)our hope(that) the two sides will work towards peace.4.it 作形式主语：1）It is/was+adj.+subject-clause可用于此句型的形容词有：clear, certain, funny, good, impossible, likely, natural, obvious, possible, probable, strange, surprising, true, unusual, wonderful 等。

“It”用法及其句型和固定搭配讲解现将It用法归纳如下：一、It用作实词表达以下概念:指代前文提到的事物，前文中的this, that；替代前文中的内容；指代一位性别不明的小孩或未知的人；指代未指明但谈话双方都知道的那件事；指代时间、天气、气候、距离等自然现象……二、It用作形式主语替代作主语的从句、动词不定式、动名词，而把真正作主语的从句、动词不定式、动名词置于句尾。
