一、作人称代词，可用来代替人、物或事。

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。

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.

2. 英语中 it 的用法

你想问
It‘s
+adj+of/for+sb
to
do
sth把
我是这样记的，别看它简单。很好记的

如果用for就是要强调后面的那个动作（do
sth）
如果用of就是强调人的品质就是前面的adj

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.
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,则只用that.
It was yesterday that I met Bob in the park.
It was in the park that I met Bob yesterday.
It was Bob that/who I met in the park yesterday.
五,另外,以下句型容易难倒中学生而又不可忽略.

It will (not) be + 时间段 + before … 要过多久(不久)才……

He made it clear that he was not interested in that subject. （9）用于强调结构。 It was Xiaoming whom(that)I met in the street last night. It was in the street that I met Xiaoming last night. It ws last night that I met Xiaoming in the street. It was I who met Xiaoming in the street last night. 2、含有“It is …”的句型 （1）It is time (for sb.) to do sth. It is (high) time that sb. did sth.(虚拟语气) （2）It is + 形容词（+of / for sb.）+ to do sth. 通常用 of 的词有 brave、clever、careful、hopeless、kind、good、naughty、nice、silly、stupid、 foolish、wise 等。 （3）It is + 形容词 + that + sb. + (should) do sth.（虚拟语气） 能用于这个句型的形容词有 strange、wonderful、natural、good、proper、right、wrong、well、 fortunate、important、necessary、useless、likely、probable、impossible 等。有时可省去 should 而直接用动词原形。如： It is important that we should pay close attention to grain.

I hope there are enough glasse for each guest to have ________.(NMET 1995) A.it B.those C.them D.one 解析：答案为 D。本题考查替代词 it 和 one 的区别。it 用于替代同类的、特定的、同一的事物；one 替代同类的、泛指的人或物。根据题意“我希望有足够的杯子使每个客人有一个。”可知应用 one 泛指 enough glasses 中的一个。 3. Was __________ that I saw last night at the concert? A.it you B.not you C.you D.that yourself 解析：答案为 A。本题考查强调句型的疑问式。只须将句序变为陈述句便不难得出答案。 4.It was back home after the experiment. B. until midnight that he didn’t go D. until midnight when he didn’t go A. not until midnight did he go C. not until midnight that he went 解析：答案为 C。此题考查的是 not…until 句型的强调结构，其最根本结构是：He did not go back home after the experiment.①,把①转变为 Not until midnight did he go back home after the experiment.②,注意②中的倒装结构， 把②中划线部分放在强调结构 It be 被强调部分 that…中进行强调， 但注意 that 从句后面不用倒装形式。
