(NMET98) It was only when I reread his poems recently _ I began to appreciate their beauty. A. untilB. thatC. thenD. so正確答案：B 此題考查強(qiáng)調(diào)句，所以用 that。2. (NMET98) I

2、 hate_ when people talk with their mouths full. A. itB. thatC. theseD. them正確答案：A 此題考查 it 作形式賓語的用法，所以選 A。3. (NMET91，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?yàn)槎ㄕZ從句中已有賓語 which。重點(diǎn)講解一、要點(diǎn)點(diǎn)撥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

3、分明朗的人。1) Who is the baby? Its my teachers son. 2) 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、時間、距離、季節(jié)等。例如： 1) Its half an hours walk from here to our school. 2) Its nice and warm here. 3) But its two oclock now, and its time for us to go to school. 3. 用作形式主語。

4、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 被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 .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 i

5、n 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 fact ,a wonder ,a good thing, etc. )thatIt is a shame that he didnt pass the exam.用心 愛心 專心 It is strange ( surprising, obvious ,true, good, possible, clear, etc. ) that 。It was clear that the

6、y 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 tickets have been sold out .4. 用作形式賓語當(dāng)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，而將真正的賓語移至句末,句子重心后移。1) We find it difficult to lea

7、rn 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/who/whom+其它”句型之中。 使用該句型有以下幾點(diǎn)請注意： 強(qiáng)調(diào)句的謂語 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)

8、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(qiáng)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 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

9、的問題。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完整的句子，只是沒被強(qiáng)調(diào)，而其他從句一般不具備這一特征。比較： 1) It was ten oclock when we got home last night. 我們昨晚到家時已十點(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

10、的。第一句不是強(qiáng)調(diào)句，when 不可改為 that,因?yàn)槿サ?it was 和 that 后，只能組成“We got home ten oclock last night. ”這是一個不完整的句子；第二句是強(qiáng)調(diào)句，that不可改為 when. 二、常用句型及考點(diǎn)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 (should+動詞原形

11、)，should 可以省去。 3. It is no good (use) doing sth. 用心 愛心 專心 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，lear

12、ned. )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，則需要前置介詞 of，而句型中的形容詞必須是能表示邏輯主語特征

13、的形容詞，常見的有bad，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(yáng)或不滿，若用否定式，則表示懷疑。 例：Its like him to leave the work to others. 他就是這樣的一個

14、人，把工作推給別人。 15. It is up to sb to do sth. 本句型表示“宜由某人做” 。II. 強(qiáng)調(diào)句型 It is+ 被強(qiáng)調(diào)部分+that/who 本句型中被強(qiáng)調(diào)部分可以是主語、賓語或狀語。強(qiáng)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(dǎo)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(dǎo)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(dāng)。 3. It looks (

15、seems) as if. . . 本句型中的 as if 引導(dǎo)一個狀語從句，常譯為“看起來好像” 。如果與事實(shí)不相符合，則用虛擬語氣. It looks as if he is ill (真的病了) . It looks as if he were ill (沒有生病) .用心 愛心 專心【模擬試題模擬試題】一. 單項(xiàng)選擇1.
