�。ㄒ唬�強調(diào)句句型

　　 1、陳述句的強調(diào)句型：It is/ was + 被強調(diào)部分（通常是主語、賓語或狀語）+ that/ who（當(dāng)強調(diào)主語且主語指人）+ 其它部分。

　　 e.g. It is in the year of 1949 that People’s Republic of China was founded.

　　 2、一般疑問句的強調(diào)句型：同上，只是把is/ was提到it前面。

　　 e.g. Is it in the year of 1949 that People’s Republic of China was founded.?

　　 3、特殊疑問句的強調(diào)句型：被強調(diào)部分（通常是疑問代詞或疑問副詞）+ is/ was + it + that/ who + 其它部分？

　　 e.g. When and where was it that you found the book?

　　 4、強調(diào)句例句：針對I met Li Ming at the railway station yesterday.句子進行強調(diào)。

　　 強調(diào)主語：It was I that (who) met Li Ming at the railway station yesterday.

　　 強調(diào)賓語：It was Li Ming that I met at the railway station yesterday.

　　 強調(diào)地點狀語：It was at the railway station that I met Li Ming yesterday.

　　 強調(diào)時間狀語：It was yesterday that I met Li Ming at the railway station.

　　 5、注意：構(gòu)成強調(diào)句的it本身沒有詞義；強調(diào)句中的連接詞一般只用that, who，即使在強調(diào)時間狀語和地點狀語時也如此，that, who不可省略；強調(diào)句中的時態(tài)只用兩種，一般現(xiàn)在時和一般過去時。原句謂語動詞是一般過去時、過去完成時和過去進行時，用It was … ，其余的時態(tài)用It is … 。

　　（二）not … until … 句型的強調(diào)句

　　 1、句型為：It is/ was not until + 被強調(diào)部分 + that + 其它部分

　　 e.g. 普通句：He didn’t go to bed until/ till he finished his homework.

　　 強調(diào)句：It was not until he finished his homework that he went to bed.

　　 2、注意：此句型只用until，不用till。但如果不是強調(diào)句型，till, until可通用；因為句型中It is/ was not … 已經(jīng)是否定句了，that后面的從句要用肯定句，切勿再用否定句了。

　�。ㄈ�）謂語動詞的強調(diào)

　　 1、It is/ was … that … 結(jié)構(gòu)不能強調(diào)謂語，如果需要強調(diào)謂語時，用助動詞do/ does或did。

　　 e.g. Do hand in your homework today. 務(wù)必今天交作業(yè)。

　　 He did call you yesterday. 昨天他確實給你打電話了。

　　 Do be careful when you cross the street. 過馬路時，務(wù)必（千萬）要小心��！

　　 2、注意：此種強調(diào)只用do/ does和did ，沒有別的形式；過去時用did ，后面的謂語動詞用原形。
