it用法專項(xiàng)練習(xí)題

1、It 的用法It 的用法在高考中也是重現(xiàn)率較高的語(yǔ)言點(diǎn)， 尤其是 it 用于強(qiáng)調(diào)句。 其考查方式多通過(guò) “單項(xiàng)填空 ”進(jìn)行，偶爾也出現(xiàn)在 “短文改錯(cuò) ”和 “完形填空 ”中。一、要點(diǎn)點(diǎn)拔1 代替上文中提到過(guò)的人或事物。指代人時(shí)，一般用于小孩或身份不十分明朗的人。1) Who is the baby? It s my teacher s son2) Who is that gentleman?Its my friend Tom . He(不可用 It) wants to see you.2 用于表達(dá)天氣、環(huán)境、時(shí)間、距離、季節(jié)等。例如：1) Its half an hour s walk fro

2、m here to our school 2) It s nice and warm here3) But its two oclock now, and its time for us to go to school 3 用作形式主語(yǔ) .it 沒(méi)有具體意義， 而只是幫助把真正的主語(yǔ)移至句子后尾， 使句子顯得平穩(wěn)一些， 能借 it 給 移至句子后尾的主語(yǔ)有三種：一種由不定式表示，一種由動(dòng)名詞表示，一種由從句表示。1) .It 替代真正的主語(yǔ) 動(dòng)詞不定式短語(yǔ).It is easier to say than to do .It is a good act to help the others.2

3、) .it 替代真正的主語(yǔ) 動(dòng)名詞短語(yǔ), 以動(dòng)名詞短語(yǔ)做主語(yǔ)的句子，主要在以no good, no use, no harm,dangerous, foolish 等詞作表語(yǔ)的句中 .Its no harm drinking running water in that area 。Its foolish talking like that.3) .it 替代從句作主語(yǔ)，用從句做主語(yǔ)的帶 it 的句子很多 ,常見(jiàn)的有下面幾類： It is a pity (a shame ,a fact ,a wonder ,a good thing,etc. )that It is a shame that h

4、e didn t pass the exam. It is strange ( surprising,obvious ,true, good,possible,clear,etc. ) that 。It was clear that they had no desire for peace. It seems (happened ,turned out,etc.)thatIt seemed that things were not as they expected. It is said ( decided ,expected ,etc)that It is said that the tic

5、kets have been sold out .4 .用作形式賓語(yǔ)。當(dāng)復(fù)合賓語(yǔ)中的賓語(yǔ)是不定式，一ing短語(yǔ)或從句往往用it作形式賓語(yǔ)，而將真正的賓語(yǔ)移至句末，句子重心后移。1) We find it difficult to learn English well in such a short time 2) We think it no use crying over spilt milk 3) We made it clear when and where we were going to have the meeting 5 用于強(qiáng)調(diào)句型，即“It is/was 被強(qiáng)調(diào)部分 that

6、/who/whom+ 其它 ”句型之中。使用該句型有以下幾點(diǎn)請(qǐng)注意： 強(qiáng)調(diào)句的謂語(yǔ) is 或 was 永遠(yuǎn)用單數(shù) .It was yesterday that I met your father in the street 不管被強(qiáng)調(diào)部分是哪種狀語(yǔ)，只能用 that連接，不得使用 where、when等連詞.It was in the street that I met your father yesterday 被強(qiáng)調(diào)部分為人時(shí)，可用who(主格或賓格)和whom(賓格)代替that,用that也行。1) It was your father that/whom /who I met in

7、the street yesterday 2) It was I that/who met your father in the street yesterday 強(qiáng)調(diào)句中 也要注意主謂一致、人稱一致和否定轉(zhuǎn)移的問(wèn)題。1) It is they who are our friends 2) It was not until ten oclock that we got home last night 注意不要混淆強(qiáng)調(diào)句和其他從句。It is wasthat為強(qiáng)調(diào)句標(biāo)志，去掉后仍可組成一個(gè)完整的句子，只是沒(méi)被強(qiáng)調(diào) ,而其他從句一般不具備這一特征。比較：1) It was ten oclock w

8、hen we got home last night 我們昨晚到家時(shí)已十點(diǎn)了。2) It was at ten oclock that we got home last night 我們昨晚是在十點(diǎn)到家的。第一句不是強(qiáng)調(diào)句，when不可改為that,因?yàn)槿サ鬷t was和that后，只能組成We gohome ten oclock lastnight.這樣一個(gè)不完整的句子；第二句是強(qiáng)調(diào)句，that不可改為when.二、常用句型及考點(diǎn)1. 形式主語(yǔ)型1.

11、her 12.

13、去時(shí)態(tài)。主句如用一般過(guò)去時(shí)，則從句用過(guò)去完成時(shí)。2. It is when 本句型中的 when 引導(dǎo)的是一個(gè)時(shí)間狀語(yǔ)從句，主句中的 it 指時(shí)間，表語(yǔ)由具體的時(shí)間充當(dāng)。3.
