          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 didnt 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。
