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(當強調(diào)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(diào)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(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 + 其他部分?
e.g. When and where was it that you were born?
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 + 其他部分
e.g. 普通句：He didn't go to bed until/ till his wife came back.
強調(diào)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(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。
三、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 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!
