E. 英语中it有哪些用法
一、作人称代词，可用来代替人、物或事。
—Who is knocking at the door?—It's me
The ant is not gathering this food for itself alone. Ithas two stomachs in its body.蚂蚁不 只是为自己采食。 它的身体里有两个胃。

二、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.It was winter. it was ten degree below zero.
It is only half an hour walk to the tall tower.
It will be lovely in the park today.
三、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 studyand 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 thework 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.
It is no use talking to him about it.
It is possible that they're finished the bridge.。
It is important that we should learn from each other andhelp each other.
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 1870's, when Marx was already in his fifties, hefound it important to study the si tuation in Russia, so hebegan 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 instryto develop very quickly.这就使得工 农业必须飞速发展。
四、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.
It is not only blind men who make such stupid mistakes. 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.
It was in your room that I met Bob yesterday.
It was Bob that I met in your room yesterday.
F. 英语中 it 的用法

（2）引词IT用于强调结构中
①英语中常用的强调结构是：“It is （was）+被强调的部分（主语、宾语或状语）+ who（that）…”。一般说来，被强调部分指人时用who，指物时用that（但that亦可指人）。注意：强调结构在强调状语时，只可用that从句，不可用which。
For example: John wore his best suit to the dance last night.（约翰昨晚他穿着他最好的一套衣服去参加舞会）
It was John who (that) wore his best suit to the dance last night.
It was his best suit (that) John wore to the dance last night.
It was last night (that) John wore his best suit to the dance.
It was to the dance that John wore his best suit last night.
②强调结构也可强调短语和从句(包括because，only when，who，whom，whose，that，which等引导的从句)。
For example:
I suspected it was on her orders that you were bringing him here.（我怀疑你是遵照她的吩咐要把他带到这儿来的）
It was because I wanted to buy a dictionary that I went to town yesterday. (我昨天是由于想买一本字典而进城的。)
It is only when you nearly lose someone that you become fully conscious of how much you value them（只有你差一点失去某一个人时，你才会充分意识到你是多么珍视他们。）
It must be your mother who (whom, that) you are thinking of.（你在想的一定是你的母亲。）
It was your brother to whom I offered a dollar for his knife yesterday.（我昨天给了你兄弟1元钱买他的小刀。）
It is Uncle Bill whose address I lost.（比尔叔叔的地址我丢了。）
It deserves attention that it is especially the verb to do which is often found in the active voice.（应该注意, 特别是行为动词常用在主动语态中。）
③表语与宾语补语偶尔也可为被强调的部分。但通常情况下，表语一般不可用作被强调的部分。
For example:
It was a doctor that he eventually became.（他最后成了一个医生）
It’s dark green that we’ve painted the kitchen.（我们把厨房漆成了深绿色）
④强调结构的时态一般应该一致。但也有例外的例子。
For example:
It is not I who am angry.（发怒的不是我。）
I was my two sisters who knew her best（是我的两个姐妹最了解他。）
I will not be you who will have to take the blame for this.（对此受责难的将不是你。）
For exceptional example:
It is Miss Williams who enjoyed reading novels as a pastime. (是威廉姆斯小姐以读小说来消遣。)
It is these very novels that Miss Williams enjoyed reading as a pastime.（威廉姆斯小姐作为消遣所读的小说就是这些。）
⑤强调结构不但可以用于独立句中，也可以用在从句之中。
For example:
It deserves attention that it is especially the verb to do which is often found in the active voice.（应该注意, 特别是行为动词常用在主动语态中。）
I suspected it was on her orders that you were bringing him here.（我怀疑你是遵照她的吩咐要把他带到这儿来的）
He told me that it was liberation that brought about a complete change in his life. （他告诉我是解放才使他的生活有了翻天覆地的变化。）
⑥强调结构中的that 与who在非正式文体中可以省略。有时还可以省去句首的It is （was）。
For example:
I suspected it was on her orders you were bringing him here.（我怀疑你是遵照她的吩咐要把他带到这儿来的）
A good, honest trade you are learning, Sir Peter! （彼得爵士，你学得是一种很好而诚实的一行啊！）
⑦强调结构中的被强调部分有时可放在句首。
For example:
Now was it that his life was done, and the fate which he could not escape was upon him.（就在这时，他的生命完结了，他所逃脱不了的命运降临了。）
⑧It is（was）之后可有一个以上的被强调部分。
For example:
It was she who was lying in the corridor and the stranger who bent over her. “Did I faint?” she asked.（是她躺在过道上，是那个陌生人在俯视她。“我晕倒了吗？”她问道。）
说明：以上是我学习这部分知识时，总结的笔记，若用得上，可要赏分啊
