英语中it的用法0
英语中it的用法
一、作非人称代词，表示时间、天气、季节、距离、环境等。
It is tea time. Mrs Tuner goes into the kitchen.到了喝茶的时间了，特纳夫人走进了厨房。
It was winter. It was ten degree below zero.现在是冬天，气温是零下10度。
It is only half an hour walk to the tall tower. 只有半小时的路程就可以到达高塔了。
It will be lovely in the park today.今天公园里一定很好玩。
二、作人称代词，可用来代替人、物或事。
—Who is that? 那是谁
—It’s me 。是我。
The ant is not gathering this food for itself alone. It has two stomachs in its body.蚂蚁不只是为自己采食。它的身体里有两个胃。
What is wrong with you ?你怎麽啦？It is nothing .没事。
三、构成强调句型。为了强调句子的某一成分，把引导词“it”用在句首，这种强调句的结构是“It is （was ）＋所强调的成分（主语、宾语、状语）＋that…”，表达的意思为“是…，正是…，就是…”。“it ”在这种句型中本身没什么实际意义。
My temperature! It’s my back that hurts.我的体温！是我的背痛。
It is not only blind men who make such stupid mistakes. 决不只有盲人才犯这样愚蠢的错误。
这里需要说明的是：如被强调的是人，则后面用who或that，如被强调的是物或其他情况，则用that。
It was yesterday that I met Bob in your room. 我就是昨天在你的房间遇见鲍勃的。
It was in your room that I met Bob yesterday. 我就是在你的房间昨天遇见鲍勃的。
It was Bob that I met in your room yesterday. 昨天我在你房间遇见的就是鲍勃。
四、作先行词。
1.作形式主语。英语中不定式、动名词、主语从句在作主语时主语往往显得很长，使整个句子看上去有点头重脚轻，这样就借助“it”来作形式上的主语，而把真正的主语移到句子后边去，使全句看上去平稳一些。“it”没有实际的意义。
It is fun for her to study, but it is difficult to study and work at the same time.对于她来说学习是有趣的，可是要边工作边学习对她来说是困难的。
It is necessary for them to get an electrician to do the work for them.对他们来说请一位电工来为他们做这项工作是必要的。
It will be no good learning without practice. 学习而不实践是不好的。
It is no use talking to him about it.和他谈这事没用。
It is possible that they’re finished the bridge.他们完成这座桥是可能的。
It is important that we should learn from each other and help each other.我们应当互相学习，互相帮助，这是很重要的。
2.作形式宾语。这种情况通常只用于能带以名词或形容词作宾语补语的动词后面。
In the 1870s, when Marx was already in his fifties, he found it
important to study the situation in Russia, so he began to learn Russian.在19世纪70年代，马克思已经五十几岁了，他觉得研究俄国的形势很重要，便开始学习俄语。
This has made it necessary for agriculture and industry to develop very quickly.这就使得工农业必须飞速发展。

高中英语 it的用法
高中英语it的用法 it的概念： it可用作人称代词、指示代词、先行词及引导词等。 it 的用法： 1、it可指天气、温度、时间、距离等。 如：It is cold today, isn't it? 2、用作人称代词，代替前文提到过的事物。 如：The dog is not acold-blooded animals. It doesn't need to hibernate. 3、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) 4、代替指示代词this，that。 如：—What's this? —It's an album. —Whose new bike is that? —It's Mary's. 注：it与one，that的区别： it=the（this, that）+名词，特指并且代替前面所提到的某特定事物。 如：He's bought a new car, so he drives it everywhere to show ito ff. one=a+名词，one指前面提到的同类事物中的不同的另一个。 如：He needs a computer, but he can't afford one. that=the+名词，that指代的名词与前面的名词属于同一类，但不属同一个。 如：The population of China is larger than that of Japan. that指代population，但其后有一个of短语作定语，以区别于the population of China。 注：it与that的异同： it指同一事物，that指同类但并不是同一事物。 如：I like the climate of Kunming more than that of Beijing. The climate of Kunming is mild, and I like it. 5、It/This/That+be+the first(second, third...) time+that-clause 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. 6、在一些相对固定的词组中，没有特殊含义，经常不翻译。 如：He's never really made it as an actor. 作为演员，他从未获得过真正的成功。 It is my turn. 轮到我了。 强调句中的it： 可以用来改变句子结构，使句子的某一成分得到强调： 1）强调句的基本句型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.
