E. 英語中it有哪些用法
一、作人稱代詞，可用來代替人、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.螞蟻不 只是為自己採食。 它的身體里有兩個胃。
When service is interrupted, as it was by last night'sstorm, John has to inform the pu blic what the company isdoing about the problem.每當供電中斷時，就像昨夜因暴風雨而造成的那樣 ，約翰就必須通知大家，公司為解決這個問題正在做些什麼。
二、作非人稱代詞，表示時間、天氣、季節、距離、環境等。
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、作先行詞。
1.作形式主語。英語中不定式、動名詞、主語從句在作主語時主語往往顯得很長，使整個句子看上去有點 頭重腳輕，這樣就藉助「it」來作形式上的主語，而把真正的主語移到句子後邊去，使全句看上去平穩一些。 「it」沒有實際的意義。
It is fun for her to study, but it is difficult to studyand work at the same time.對於她來 說學習是有趣的，可是要邊工作邊學習對她來說是困難的。
It is necessary for them to get an electrician to do thework for them.對他們來說請一位電工 來為他們做這項工作是必要的。
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.作形式賓語。這種情況通常只用於能帶以名詞或形容詞作賓語補語的動詞後面。
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世紀70年代，馬克思已經五十幾歲了，他覺得研 究俄國的形勢很重要，便開始學習俄語。
This has made it necessary for agriculture and instryto develop very quickly.這就使得工 農業必須飛速發展。
四、構成強調句型。為了強調句子的某一成分，把引導詞「it」用在句首，這種強調句的結構是「It is （was ）＋所強調的成分（主語、賓語、狀語）＋that…」，表達的意思為「是…，正是…，就是…」。「it 」在這種句型中本身沒什麼實際意義。
My temperature! It's my back that hurts.
It is not only blind men who make such stupid mistakes. 這里需要說明的是：如被強調的是人，則後面用who或that， 如被強調的是物或其他情況，則用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. 英語中 it 的用法
你想問
It『s
+adj+of/for+sb

do
sth把
我是這樣記的，別看它簡單。很好記的
如果用for就是要強調後面的那個動作（do
sth）
如果用of就是強調人的品質就是前面的adj

（2）引詞IT用於強調結構中
①英語中常用的強調結構是：「It is （was）+被強調的部分（主語、賓語或狀語）+ who（that）…」。一般說來，被強調部分指人時用who，指物時用that（但that亦可指人）。注意：強調結構在強調狀語時，只可用that從句，不可用which。
For example: John wore his best suit to the dance last night.（約翰昨晚他穿著他最好的一套衣服去參加舞會）
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強調結構也可強調短語和從句(包括because，only when，who，whom，whose，that，which等引導的從句)。
For example:
I suspected it was on her orders that you were bringing him here.（我懷疑你是遵照她的吩咐要把他帶到這兒來的）
It was because I wanted to buy a dictionary that I went to town yesterday. (我昨天是由於想買一本字典而進城的。)
It is only when you nearly lose someone that you become fully conscious of how much you value them（只有你差一點失去某一個人時，你才會充分意識到你是多麼珍視他們。）
It must be your mother who (whom, that) you are thinking of.（你在想的一定是你的母親。）
It was your brother to whom I offered a dollar for his knife yesterday.（我昨天給了你兄弟1元錢買他的小刀。）
It is Uncle Bill whose address I lost.（比爾叔叔的地址我丟了。）
It deserves attention that it is especially the verb to do which is often found in the active voice.（應該注意, 特別是行為動詞常用在主動語態中。）
③表語與賓語補語偶爾也可為被強調的部分。但通常情況下，表語一般不可用作被強調的部分。
For example:
It was a doctor that he eventually became.（他最後成了一個醫生）
It』s dark green that we』ve painted the kitchen.（我們把廚房漆成了深綠色）
④強調結構的時態一般應該一致。但也有例外的例子。
For example:
It is not I who am angry.（發怒的不是我。）
I was my two sisters who knew her best（是我的兩個姐妹最了解他。）
I will not be you who will have to take the blame for this.（對此受責難的將不是你。）
For exceptional example:
It is Miss Williams who enjoyed reading novels as a pastime. (是威廉姆斯小姐以讀小說來消遣。)
It is these very novels that Miss Williams enjoyed reading as a pastime.（威廉姆斯小姐作為消遣所讀的小說就是這些。）
⑤強調結構不但可以用於獨立句中，也可以用在從句之中。
For example:
It deserves attention that it is especially the verb to do which is often found in the active voice.（應該注意, 特別是行為動詞常用在主動語態中。）
I suspected it was on her orders that you were bringing him here.（我懷疑你是遵照她的吩咐要把他帶到這兒來的）
He told me that it was liberation that brought about a complete change in his life. （他告訴我是解放才使他的生活有了翻天覆地的變化。）
⑥強調結構中的that 與who在非正式文體中可以省略。有時還可以省去句首的It is （was）。
For example:
I suspected it was on her orders you were bringing him here.（我懷疑你是遵照她的吩咐要把他帶到這兒來的）
A good, honest trade you are learning, Sir Peter! （彼得爵士，你學得是一種很好而誠實的一行啊！）
⑦強調結構中的被強調部分有時可放在句首。
For example:
Now was it that his life was done, and the fate which he could not escape was upon him.（就在這時，他的生命完結了，他所逃脫不了的命運降臨了。）
⑧It is（was）之後可有一個以上的被強調部分。
For example:
It was she who was lying in the corridor and the stranger who bent over her. 「Did I faint?」 she asked.（是她躺在過道上，是那個陌生人在俯視她。「我暈倒了嗎？」她問道。）
說明：以上是我學習這部分知識時，總結的筆記，若用得上，可要賞分啊
