   A. this        B. these     C. that          D. it
一、代词it
1.用作人称代词代替上文提到过的人或事物，（有时不特指某件事物，而代表前面已提
到的或者将会发生的某件事情，或者是谈话双方都明白的情况，如前面第2题）      
Tom’s ill. Have you heard about it?

2. 用作指示代词，（起着this 或that 的作用）指一个人或一件事情。

3. 指时间、距离、价值、天气和自然现象等。

二、引导词it
1. It 常作形式主语，把真正的主语置于句后，真正的主语通常为不定式、动名词、主语
    从句。
It is easy to buy a new radio.
It is no use telling him that.

提示：it 作形式主语，that从句作真正主语，常见的句型有：
a. It be + 形容词（obvious, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) + that 从句
b. It be + 名词词组（ no wonder, an honor, a good thing, a pity, no surprise, etc. )+ that 从句
c. It be + 过去分词（ said, reported, thought,expected, decided, announced, arranged, etc.) + that 从句

ber, ____ personally I doubt very much. (NMET, 1999 )      ( D )
A.it        B. that      C.when        D. which
2. It 作形式宾语，真正宾语放在宾语补足语
    后面，真正宾语通常为不定式，动名词，
    宾语从句。

Sure it (=the unforgettable moment ).

1.可以用来强调句中的主语、宾语、状语（从句），
结构为：
It is (was) + 被强调部分[sb.] +who (that)
It is (was) + 被强调部分[sth.] +that
(例句参看练习试卷）

ment in the lab last night.  (   B      )
A. whom   B. that    C. which    D. where
It was because of bad weather ____ the foot-
ball match had to be put off.  (   D     )

It was ten years ____ Miss Gao left here. (  C    )
A. That      B. when      C. since      D. as
对强调句型的识别：
可用下面方法识别强调句型： 把强调句的
标志词 it is / was … that  拿掉，若能还原出
句法结构完整的句子来，则为强调句，否则
不是强调句。
It was eight o’clock ____ I left home.(   C     )
It was at eight o’clock ____ I left home.(   A    )
A. that    B. since      C. when       D. while
2.对“ not…until…”的特殊强调句型：
It is /was  not until +时间状语（从句）+that
He didn’t get home until midnight.
It was not until midnight that he got home.It was _____ back home after the experiment. ( C )
A.not until midnight did he go        B.until midnight that he didn’t go
C.not until midnight that he went     D.until midnight when he didn’t go
3.强调句的疑问结构：
（1）一般疑问句：
Is/was it+被强调部分+that(who)+剩余部分如原句为：
Does he read this book every day?
Is it this book that he reads every day?
（2）特殊疑问句： （只能对疑问词强调）疑问词+is/was+被强调部分+ that(who)+剩余
部分：
Who came to see you this morning?
Who was it that came to see you this morning?
4. 含有定语从句的强调句：
It was in the lab that was set up by Mr. Smith that they finished the experiment.
It was in Beihai Park ____ they made a date for the first time _____the  old couple told us  their love story. (      )
5. 强调宾语从句中的疑问词时：
主语+谓语+疑问词+it is/was+that+宾语从句
I don’t know where he comes from.
I don’t know where it is that he comes from.
6.需要注意的地方：
（1）如果原句中的谓语动词为现在或将来时的各种时态，就用“ it is…”,如果原句中的谓
语动词为过去时的各种时态，则用“it was…”
（2）不论被强调的主语是单数还是复数，一律用“it is/was +who(that).
