It is that/who 強(qiáng)調(diào)句句型用法
It is that/who 強(qiáng)調(diào)句句型用法
當(dāng)需要強(qiáng)調(diào)句中的主語、賓語、狀語時，我們常用“It is/was+被強(qiáng)調(diào)部分+that/who...”這樣的句型，被強(qiáng)調(diào)的部分放在前面，其它部分置于that之后。強(qiáng)調(diào)的主語如果是人，that可以換用who。如何區(qū)分這種強(qiáng)調(diào)句句型與that從句？如果把這種句型中的句型結(jié)構(gòu)部分(It is/was...that/who...)劃掉后，是一個完整無缺的句子即是強(qiáng)調(diào)句。
He read three books in the library yesterday.
我們分別可以強(qiáng)調(diào)主語、賓語、地點(diǎn)狀語和時間狀語。如：
It was he who(that)read three books in the library yesterday.(強(qiáng)調(diào)主語)
It was three books that he read in the library yesterday.(強(qiáng)調(diào)賓語)
It was in the library that he read three books yesterday.(強(qiáng)調(diào)地點(diǎn)狀語)
It was yesterday that he read three books in the library.(強(qiáng)調(diào)時間狀語)
在使用It is/was...that/who...強(qiáng)調(diào)句型時應(yīng)注意以下幾點(diǎn)：
1、當(dāng)被強(qiáng)調(diào)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(qiáng)調(diào)狀語時，只有that,不用when、where，如：
It is at 5 o'clock that the train will arrive. 五點(diǎn)鐘是火車到達(dá)的時間。
3、被強(qiáng)調(diào)的部分是主語時，注意主謂語動詞和被強(qiáng)調(diào)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(qiáng)調(diào)句為“Is (was) it + that...?”；特殊疑問句為：“特殊疑問詞+ is (was) +that...?”結(jié)構(gòu)。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(qiáng)調(diào)句型擴(kuò)展講解
1、It is not until + 被強(qiáng)調(diào)部分 + that ...
該句型也是強(qiáng)調(diào)句型。主要用于強(qiáng)凋時間狀語，譯成漢語”直到...才..”，可以說是 not ... until ... 的強(qiáng)調(diào)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(dǎo)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(jié)構(gòu)。
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(dǎo)的主語從句。該結(jié)構(gòu)常譯為”據(jù)說（據(jù)報(bào)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(yīng)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(jié)構(gòu)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.
