it的用法讲解---绝对经典系列

it的用法讲解---绝对经典系列嘿，伙计们！今天我们要来聊聊一个超级神奇的单词——it。

这个词在我们的日常生活中无处不在，它既可以作为主语、宾语，也可以作为形容词、副词。

而且，它还可以指代很多东西，比如动物、物品、技术等等。

那么，it到底是怎么来的呢？它又有哪些用法呢？别着急，我们一一来看。

我们来说说it的基本用法。

it作为一个单词，最基本的意思就是“它”。

比如说，我们看到一只猫，就可以说：“It is a cat.”(这是一只猫)。

it也可以作为主语或宾语使用。

比如说，我们可以说：“It is raining outside.”(外面正在下雨)或者“I saw it at the store.”(我在商店里看到了它)。

这里，it就是一个主语，表示下雨这个动作。

而当我们把it作为宾语时，它就表示被下雨这个动作所影响的对象。

比如说，我们可以说：“The book got wet because of it.”(因为下雨，书湿了)。

这里的it就是宾语，表示书这本书。

接下来，我们来看看it的其他用法。

首先是作为形容词使用。

这时候，it通常用来修饰名词，表示这个名词的特征或者属性。

比如说，我们可以说：“This is a nice it.”(这是一个不错的it)。

这里的nice就是形容词，修饰it这个名词。

而当我们用it来修饰动词时，它就表示这个动作的结果或者状态。

比如说，我们可以说：“He fixed it quickly.”(他很快就修好了它)。

这里的quickly就是副词，修饰fixed这个动词。

除了这些基本用法之外，it还有很多其他的特殊用法。

比如说，我们可以用it来指代上文提到的某个事物或者概念。

这样一来，我们就可以避免重复使用同一个词，让文章更加简洁明了。

比如说，我们可以这样说：“I love this song. It always makes me happy.”(我喜欢这首歌。

它总是让我开心)。

高中英语it的基本用法

高中英语it的基本用法''It'' 用法及其句型和固定搭配，是高中英语语法的重点、难点，又是近几年高考的热点，因此应给予充分的重视。

初小内容归纳：一、it指代（后行）作用:1.It的基本用法是用来指代上文所提到的事物。

如橙子妈妈经常给学生用最简单的方法举例：I have a pen and I like it.2.学会区分这几组词：it, that, one, the one, ones, the ones用于指代:橙子妈妈归纳的口诀：it指代同名同物；one指代同名异物, that 指代抽象物体居多即it代替上文提及的原物(复数用they)；one指代上文提及的、泛指的可数名词单数（复数ones）；that指代上文提及的定指的可数名词单数或不可数名词（复数those）, the ones 相当于these, those。

注意：指代不明身份（例如有人在外面叫你或者敲门）或性别的人（如小baby）也用it；指代喜爱的事物或宠物也可用she / he。

A：Who''s it (knocking at the door)? B: It''s me.二、虚义it:（初中阶段的重点内容）虚义it指用作没有具体语义的主语，如表示时间、天气、距离、温度等概念的用法。

It is a good day.It cost me 10 dollars.高中内容归纳一、形式it:由于句子结构的需要，常常把it作形式主语，而把真正的主语放后置。

小伙伴们熟不熟悉！1．形式主语：不定式、动名词以及主语从句作主语时，为避免“头重脚轻”，要将真正的主语后置。

It is obvious that he will win the match. （主语从句作主语）It was worthwhile searching for his ''roots.'' （动名词作主语）It took me 10 dollars to buy the book. （不定式作主语）2．形式宾语：当不定式、动名词、that 从句作宾语，又有自己的宾语补语时，要用it 作形式宾语，而把真正的宾语后置。
