高中英語it用法講解

1. 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.

2. 英語中 it 的用法

你想問
It『s
+adj+of/for+sb
to
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

3. 本人現急需一篇英語論文，題目是it在中學英語中的用法，急啊！！！

it在中學英語里的用法
英語科組 葉偉娟
It 看似個非常簡單的詞,但在英語使用中無處不在.它的大多數用法對中學生來說,不難掌握,但也有個別用法是中學生掌握的難點.因此,在這里,我嘗試著把它們作一些歸納.
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 food for itself alone. It has two stomachs in its body.
When service is interrupted, as it was by last night's storm, John has to inform the public what the company is doing about the problem.
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's 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,這時就可藉助"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 study and work at the same time.
It is necessary for them to get an electrician to do the work for them.
It will be no good learning without practice.
It is no use talking to him about it.
It is possible that they've finished the bridge.
It is important that we should learn from each other and help each other.
2.作形式賓語.不定式,動名詞和賓語從句在句子中作賓語,後跟賓語補足語時,必須使用"it"作形式賓語,而把真正的賓語放在賓語補足語之後.
I think it no use arguing with him.
I found it very interesting to study English.
This has made it necessary for agriculture and instry to develop very quickly.
He made it clear that he was not interested in this subject.
3. 作形式賓語.用在一些一般不接賓語從句或接此類從句會有歧義的及物動詞後面.
I hate it when someone speaks with his mouth full.
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.
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,以下句型容易難倒中學生而又不可忽略.
It was + 時間段+ before… 過了多久才……
It was not long before … 不久就……
It will (not) be + 時間段 + before … 要過多久(不久)才……
It was not long before he sensed the danger of the position.
It was three days before he came back.
It will be half a year before you graate from this school.
It is/was not until … that …
It was not until he told me that I realized what a big mistake I had made.
以上是我在教學過程中的一些歸納整理,不完善的地方以後還會不斷補充.

高中英語之 it 的用法詳解首先先講一下 it 的用法，然後在出幾道題 一、考點聚焦 1、it 的基本用法 （1）用作人稱代詞，代替前文提到過的事物。 The train has arrived. It arrived half an hour ago. （2）用以代替提示代詞 this, that。 —What』s this? —It』s a knife. —It』s mine. —Whose watch is that? （3）起指示代詞的作用，指一個人或事物。 —Who is knocking at the door? （4）指環境情況等。 It was very noisy (quiet) at the very moment. （5）指時間、季節等。 —What time is it? —It』s eight o』clock. —It』s me.

It is as pity that you didn』t read the book. （8）作形式賓語。 I think it no use arguing with him. I found it very interesting to study English. He made it clear that he was not interested in that subject. （9）用於強調結構。 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.(虛擬語氣) （2）It is + 形容詞（+of / for sb.）+ to do sth. 通常用 of 的詞有 brave、clever、careful、hopeless、kind、good、naughty、nice、silly、stupid、 foolish、wise 等。 （3）It is + 形容詞 + that + sb. + (should) do sth.（虛擬語氣） 能用於這個句型的形容詞有 strange、wonderful、natural、good、proper、right、wrong、well、 fortunate、important、necessary、useless、likely、probable、impossible 等。有時可省去 should 而直接用動詞原形。如： It is important that we should pay close attention to grain. It is natural that he（should）say so. （4）It is no use/ good + doing sth. It is no use trying again = It is of no use to try again. （5）It is + 被強調部分 + that/who + … Was it in the street that you met her? Who was it that called him「comrade」? It was not until yesterday that I met my old friend. It is in a small factory that my brother is going to work.（注意上述各句均為強調句型的「考 點」） 比較：It is a small factory where my brother is going to work.（定語從句） （6）It is said/reported/announced/ (well) known … that… （7）It is/was + 時間 + since … 從……已多久了。 It is three years since I met him in Beijing. It was a long time since I (had) lived in that small mountain village with these farmers. （注意兩句中的時態） It is five months since I arrived in New York.我到紐約已經五個月了。 It is five months since I was in New York.我離開紐約已經五個月了。 （注意：終止性動詞表示從動作發生時算起；如果是狀態動詞或持續性動詞，則從動作或狀態結束時 算起。） （8）It is + 時間 + before … 這個句型和上面句型中時間都是時間段，如 long、years、months、weeks、five days、three hours、 twenty minutes 等。不過主句的時態多用一般將來時或一般過去時。 It will be several years before we meet again. 我們要過好幾年才能再見面。 It was not long before they set out for the front. 不久他們就出發去了前線。 （9）It is /was/will be the first/second/third … time that … It is the first time that I have been here. It was the second time that he had seen the film. （10）It is up to sb. to do sth … 應由某人做某事。 It is up to you to decide whether we start or not. 二、精典名題導解 選擇填空 1. _________ is a fact that English is being accepted as an international language.(NMET 1995) A.There B.This C.That D.It 解析：答案為 D。本題考查作形式主語的用法。that 引導的從句是真正的主語。為避免頭重腳輕而平 衡句子結構，將 it 置於句首作形式主語。 2. I hope there are enough glasse for each guest to have ________.(NMET 1995) A.it B.those C.them D.one 解析：答案為 D。本題考查替代詞 it 和 one 的區別。it 用於替代同類的、特定的、同一的事物；one 替代同類的、泛指的人或物。根據題意「我希望有足夠的杯子使每個客人有一個。」可知應用 one 泛指 enough glasses 中的一個。 3. Was __________ that I saw last night at the concert? A.it you B.not you C.you D.that yourself 解析：答案為 A。本題考查強調句型的疑問式。只須將句序變為陳述句便不難得出答案。 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：答案為 C。此題考查的是 not…until 句型的強調結構，其最根本結構是：He did not go back home after the experiment.①,把①轉變為 Not until midnight did he go back home after the experiment.②,注意②中的倒裝結構， 把②中劃線部分放在強調結構 It be 被強調部分 that…中進行強調， 但注意 that 從句後面不用倒裝形式。

四、作形式主語，替代主語從句，動詞不定式，或動名詞短語：

5. 高中英語（that \ it)

1.it
既可以做
形式賓語
也可以做
形式主語
.
在這里是做形式賓語，that沒這種用法.
2.句子所說的是專同個事情（water），用it指代屬說明，顯得更加有閱讀行.如果用that，那可以說是表示另一個事件.
我覺得這道題目最主要是考
形式賓語
it的用法.

6. 高中 It 的用法 求助~

worthy才是形容詞
回答里是it's 明顯要表語
worth sth/it/doing
而且這個不是it的用法
而是worth 的用法

7. it在英語中的用法

It 作形式賓語的常見句型：
1. verb+ it+ adj./noun (for/of) to do/clause (verb=think, believe, suppose, consider, feel, make, keep…)

五、強調句型
It is/was+被強調部分+ that(who)… 強調句型用來強調謂語動詞以外的任何句子成分。當被強調部分是人時也可以用who。
在使用強調句型時需注意以下幾點：
1. 請注意強調句型的特殊疑問句
2. 在強調原因狀語從句時，只能強調由because所引導的從句。
3. 在強調not … until結構時必須把not與until一起放到被強調的位置上。
4. 注意強調句型與定語從句的區別。
六、It 常用的固定搭配
1. make it
(1).在口語當中相當於succeed,表示：成功、做到、說定、趕上、及時到達 。
