it用法專項練習題

1、It的用法It的用法在高考中也是重現(xiàn)率較高的語言點，尤其是it用于強調(diào)句。其考查方式多通過“單項填空”進行，偶爾也出現(xiàn)在“短文改錯”和“完形填空”中。一、要點點拔1代替上文中提到過的人或事物。指代人時，一般用于小孩或身份不十分明朗的人。1) Who is the baby? Its my teachers son2) Who is that gentleman? It's my friend TomHe(不可用It) wants to see you2用于表達天氣、環(huán)境、時間、距離、季節(jié)等。例如： 1) Its half an hours walk from here to our s

2、chool2) Its nice and warm here3) But it's two o'clock now, and it's time for us to go to school3用作形式主語.it 沒有具體意義，而只是幫助把真正的主語移至句子后尾，使句子顯得平穩(wěn)一些，能借it 給移至句子后尾的主語有三種：一種由不定式表示，一種由動名詞表示，一種由從句表示。  1).It 替代真正的主語動詞不定式短語.     It is easier to say than to do .  

3、   It is a good act to help the others. 2).it 替代真正的主語動名詞短語,以動名詞短語做主語的句子，主要在以no good, no use, no harm, dangerous, foolish 等詞作表語的句中. Its no harm drinking running water in that area。 Its foolish talking like that.3).it 替代從句作主語，用從句做主語的帶it 的句子很多,常見的有下面幾類：  It is a pity (a shame ,a fac

4、t ,a wonder ,a good thing,etc. )that      It is a shame that he didnt 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 s

5、eems (happened ,turned out,etc.)that      It seemed that things were not as they expected. It is said  ( decided ,expected ,etc)that      It is said that the tickets have been sold out .4.用作形式賓語。當復(fù)合賓語中的賓語是不定式,ing短語或從句往往用it作形式賓語,而將真正的賓語

6、移至句末,句子重心后移。1) We find it difficult to learn English well in such a short time2) We think it no use crying over spilt milk3) We made it clear when and where we were going to have the meeting5用于強調(diào)句型，即“It is/was被強調(diào)部分that/who/whom+其它”句型之中。 使用該句型有以下幾點請注意： 強調(diào)句的謂語is或was永遠用單數(shù). It was yesterday that I met y

7、our father in the street不管被強調(diào)部分是哪種狀語，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被強調(diào)部分為人時，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 the street yesterday2) It was I that/who met your father in the street yesterday強調(diào)句中 也要注意主

8、謂一致、人稱一致和否定轉(zhuǎn)移的問題。1) It is they who are our friends2) It was not until ten o'clock that we got home last night注意不要混淆強調(diào)句和其他從句。It is wasthat為強調(diào)句標志，去掉后仍可組成一個完整的句子，只是沒被強調(diào),而其他從句一般不具備這一特征。比較： 1) It was ten o'clock when we got home last night我們昨晚到家時已十點了。2) It was at ten o'clock that we got home

9、last night我們昨晚是在十點到家的。第一句不是強調(diào)句，when不可改為that,因為去掉it was和that后，只能組成“We got home ten o'clock last night”這樣一個不完整的句子；第二句是強調(diào)句，that不可改為when二、常用句型及考點I. 形式主語型 1. It is clear (obvious，true，possible，certain) that 2. It is important (necessary，right，strange，natural)that 掌握本句型，應(yīng)該記住所列舉的形容詞，并且記住that后的從句應(yīng)用虛擬語氣

10、(should+動詞原形)，should可以省去。 3. It is no good (use) doing sth 4. It is a pity (a shame ) that 本句型中，that后的從句一般用虛擬語氣 (should十動詞原形)，should可以省去。表示出乎意料，常譯為“竟然”。沒有這種意義時，則不用虛擬語氣。 5. It is time (about time，high time) that 本句型中that后的從句應(yīng)該用虛擬語氣。 6. It is the first (second)time that 7. It is said (reported，learned

11、)that 8. It is suggested (ordered) that 本句型中的過去分詞應(yīng)該是表示請求、建議、命令等的詞，that后的從句要用虛擬語氣(should十動詞原形)，should可以省略。常譯為“據(jù)建議；有命令”。 9. It happens (seems，appears) that 10. It takes sbto do sth 11. It doesnt matter whether 12. It is kind (of sb) to do sth 本句型中的不定式如果需要邏輯主語，則須要前置介詞of，而句型中的形容詞必須是能表示邏輯主語特征的形容詞，常見的有bad

12、，brave，careless，clever，cruel，foolish，honest，horrible，kind，lazy，modest，naughty, polite，rude，silly, stupid，wise，wrong等。 13. It is necessary ( for sb) to do sth 14. It is (just) like sb to do sth 本句型為“某人(恰恰)是樣子”。用來表示贊揚或不滿，若用否定式，則表示懷疑。 例：It's like him to leave the work to others 他就是這樣的一個人，把工作推給別人。 1

13、5. It is up to sb to do sth 本句型表示“誼由某人做”。II強調(diào)句型 It is+ 被強調(diào)部分+that/who 本句型中被強調(diào)部分可以是主語、賓語或狀語。強調(diào)的主語如果是人，that可以由who換用。III其他句型 1. It issince 本句型主句中用時間作表語，一般用現(xiàn)在時或完成時，since引導的從句常用瞬間動詞的一般過去時態(tài)。主句如用一般過去時，則從句用過去完成時。 2. It iswhen 本句型中的when引導的是一個時間狀語從句，主句中的it指時間，表語由具體的時間充當。 3. It looks (seems) as if 本句型中的as if引導

14、一個狀語從句，常譯為“看起來好像”。如果與事實不相符合，則用虛擬語氣 例1 It looks as if he is ill (真的病了) . 例2 It looks as if he were ill (沒有生病) .一替代詞it, that, (the) one(s), those的用法辨析1.
