一、強調句句型

1. 陳述句的強調句型：It is/ was + 被強調部分(通常是主語、賓語或狀語)+ that/ who(當強調主語且主語指人)+ 其他部分。

e.g. It was yesterday that he met Li Ping.

2. 一般疑問句的強調句型：同上，只是把is/ was提到it前面。

e.g. Was it yesterday that he met Li Ping?

3. 特殊疑問句的強調句型：被強調部分(通常是疑問代詞或疑問副詞)+ is/ was + it + that/ who + 其他部分?

e.g. When and where was it that you were born?

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

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

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

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

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

5. 注意：構成強調句的it本身沒有詞義;強調句中的連接詞一般只用that, who，即使在強調時間狀語和地點狀語時也如此，that, who不可省略;強調句中的時態只用兩種，一般現在時和一般過去時。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 ... ，其余的時態用It is ... 。

二、not … until … 句型的強調句

1. 句型為：It is/ was not until + 被強調部分 + that + 其他部分

e.g. 普通句：He didn’t go to bed until/ till his wife came back.

強調句：It was not until his wife came back that he went to bed.

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

三、謂語動詞的強調

1. It is/ was ... that ... 結構不能強調謂語，如果需要強調謂語時，用助動詞do/ does或did。

e.g. Do sit down. 務必請坐。

He did write to you last week. 上周他確實給你寫了信。

Do be careful when you cross the street. 過馬路時，務必(千萬)要小心啊!

2. 注意：此種強調只用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。
