當需要強調句中的主語、賓語、狀語時，我們常用“It is/was+被強調部分+that/who...”這樣的句型，被強調的部分放在前面，其它部分置于that之后。強調的主語如果是人，that可以換用who。如何區(qū)分這種強調句句型與that從句？如果把這種句型中的句型結構部分(It is/was...that/who...)劃掉后，是一個完整無缺的句子即是強調句。
He read
three books in the
library yesterday.
我們分別可以強調主語、賓語、地點狀語和時間狀語。如：
It was he who(that)read three books in the library yesterday.(強調主語)
It was three books that he read in the library yesterday.(強調賓語)
It was in the library that he read three books yesterday.(強調地點狀語)
It was yesterday that he read three books in the library.(強調時間狀語)
在使用It is/was...that/who...強調句型時應注意以下幾點：
1、當被強調部分指人時，可用that，也可以用who;指物時，只能用that,如：
It was Tom who(that)I met last week.我上周遇見的就是湯姆。
It is a new boke that his
brother wants to buy.他的弟弟就想買一個新博客。
2、強調狀語時，只有that,不用when、
where，如：
It is at 5 o'clock that the
train will
arrive. 五點鐘是火車到達的時間。
3、被強調的部分是主語時，注意主謂語動詞和被強調的主語保持一致，如：
It is he who is late. 是他遲到了。
It is they that were late.是他們遲到了。
4、一般疑問句的強調句為“Is (was) it + that...?”；特殊疑問句為：“特殊疑問詞+ is (was) +that...?”結構。如:
Was it ten
years ago that his
father died?（他的父親是十年前去世的嗎？）
When is it that you will set off?（你到底什么時候出發(fā)？）
It is/was...that/who...強調句型擴展講解
1、It is not
until + 被強調部分 + that ...
該句型也是強調句型。主要用于強凋時間狀語，譯成漢語”直到...才..”，可以說是 not ... until ... 的強調形式。
It was not until she took off her dark
glasses that I
realized she was a
famous film star.
= Not until she took off her dark glasses did I
realize she was a famous film star.
= I didn’t realize she was a famous film star until she took off her dark glasses.
3. It is
clear (
obvious, true,
possible,
certain....) that .....
該句型中it 是形式主語，真正的主語是that 引導的主語從句，常譯為”清楚（顯然，真的，肯定．．．）” 是主語從句最常見的一種結構。
It is very clear that he’s
round and tall like a tree.
= That he’s round and tall like a tree is very clear.
4. It is
important (
necessary,
right,
strange,
natural...) that ...
該句型和上一個同屬一個句型。由于主句中的形容詞不同，that 后的從句中要用虛擬語氣（
should + 動詞原形），should 可以省去。建議記住該句型中的形容詞。
It is important that we (should)
learn English well.
It is necessary that he (should)
remember these words.
5. It is said (
reported,
learned....) that ...
該句型中的it 仍是形式主語，真正主語是that 引導的主語從句。該結構常譯為”據(jù)說（據(jù)報道，據(jù)悉．．．）”。
It is said that he has come to
Beijing.
It is reported that
another earth satellite has been put into
orbit.
6. It is
suggested (
ordered ... ) that ...
該句型和上一個同屬一個句型。主句中的過去分詞是表示請求，建議，命令等詞時，that 后的從句要用虛擬語氣（should + 動詞原形），should 可以省。常譯為”據(jù)建議；有命令．．．）
It is suggested that the
meeting ( should ) be put off.
It was ordered that we ( should ) arrive
there in two
hours.
7. It is a pity ( a
shame ... ) that ...
該句型中，that后的從句一般用虛擬語氣（should + 動詞原形），should可省去．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。
It is a pity that such a
thing ( should )
happen in your
class.
這種事竟然發(fā)生在你們班上，真是遺憾！
It is a pity that he is ill. 他生病了，真遺憾！
8. It is time (
about time ,high time ) that ...
該句型中that 后的從句應該用虛擬語氣，值得注意的是① 常用過去時態(tài)表示虛擬．② 有時也用should + 動詞原形，should 不能省。常譯為”是（正是）．．．的時侯．．．”。
It is time that
children should go to bed.
= It is time that children went to bed.
9. It is the
first (
second ... ) time that ...
該句型要和上一個句型區(qū)別開來。該句型中的 that 從句不用虛擬語氣，而用完成時態(tài)。
至于用什么完成時態(tài)，由主句的謂語動詞的時態(tài)決定。如果是一般現(xiàn)在時，后面從句用現(xiàn)在完成時態(tài)；如果是一般過去時，后面從句則用過去完成時態(tài)。該結構中 that 可以省去；it有時用 this 替換．常譯為”是第一（二）．．．次．．．”。
It is the first time I have been here.
= This is the first time I have been here.
