It的用法及練習題

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。1 It was only when I reread his poems recently _ I began to appreciate their beautyAuntil Bthat Cthen Dso正確答案：B 此題考查強調(diào)句，所以用that。2 I hate _when people talk with their mouths full Ait Bthat Cthese Dthem正確答案：A 此題考查it作形式賓語的用法，所以選A。3

2、(短文改錯)David and I did not agree and David pointed to a path which he thought it wouldprobably lead to a village正確答案：去掉it，因為定語從句中已有賓語which。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清楚朗的人。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、

3、環(huán)境、時間、距離、季節(jié)等。例如： 1) Its half an hours walk from here to our school2) 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.  &

4、#160;  It is easier to say than to do .       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

5、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 fact ,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

6、desire for peace.   It seems (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。當復合賓語中的賓語

7、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 meeting5用于強調(diào)句型，即“It is/was被強調(diào)局部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

8、單數(shù). It was yesterday that I met your father in the street 不管被強調(diào)局部是哪種狀語，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)局部為人時，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 yesterday 2) It was I that/who met your fath

9、er in the street yesterday 強調(diào)句中 也要注意主謂一致、人稱一致和否認轉(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 wa

10、s at ten o'clock that we got home 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

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，那么不用虛擬語氣。 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.

12、e that 7. It is said (reported，learned)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，那么須要前

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，假設(shè)用否認式，那么表示疑心。 例：It's like him to leave
