⒈ 陳述句的強(qiáng)調(diào)句型：It is/ was + 被強(qiáng)調(diào)部分(通常是主語(yǔ)、賓語(yǔ)或狀語(yǔ))+ that/ who(當(dāng)強(qiáng)調(diào)主語(yǔ)且主語(yǔ)指人)+ 其他部分。

如：It was yesterday that he met Li Ping.

⒉ 一般疑問(wèn)句的強(qiáng)調(diào)句型：同上，只是把is/ was提到it前面。如：Was it yesterday that he met Li Ping?

⒊ 特殊疑問(wèn)句的強(qiáng)調(diào)句型：被強(qiáng)調(diào)部分(通常是疑問(wèn)代詞或疑問(wèn)副詞)+ is/ was + it + that/ who + 其他部分?如：When and where was it that you were born?

⒋ 強(qiáng)調(diào)句例句：針對(duì)I met Li Ming at the railway station yesterday.句子進(jìn)行強(qiáng)調(diào)。① 強(qiáng)調(diào)主語(yǔ)：It was I that (who) met Li Ming at the railway station yesterday.

② 強(qiáng)調(diào)賓語(yǔ)：It was Li Ming that I met at the railway station yesterday.③ 強(qiáng)調(diào)地點(diǎn)狀語(yǔ)：It was at the railway station that I met Li Ming yesterday.④ 強(qiáng)調(diào)時(shí)間狀語(yǔ)：It was yesterday that I met Li Ming at the railway station.⑤注意：構(gòu)成強(qiáng)調(diào)句的it本身沒(méi)有詞義；強(qiáng)調(diào)句中的連接詞一般只用that、who，即使在強(qiáng)調(diào)時(shí)間狀語(yǔ)和地點(diǎn)狀語(yǔ)時(shí)也如此，that， who不可省略；強(qiáng)調(diào)句中的時(shí)態(tài)只用兩種，一般現(xiàn)在時(shí)和一般過(guò)去時(shí)。原句謂語(yǔ)動(dòng)詞是一般過(guò)去時(shí)、過(guò)去完成時(shí)和過(guò)去進(jìn)行時(shí)，用It was…，其余的時(shí)態(tài)用It is…

⒈ 句型為：It is/ was not until + 被強(qiáng)調(diào)部分 + that + 其他部分如：普通句：He didn't go to bed until/ till his wife came back.如：強(qiáng)調(diào)句：It was not until his wife came back that he went to bed.

⒉ 注意：此句型只用until，不用till。但如果不是強(qiáng)調(diào)句型，till， until可通用;因?yàn)榫湫椭蠭t 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。

⒈ It is/ was …… that …… 結(jié)構(gòu)不能強(qiáng)調(diào)謂語(yǔ)，如果需要強(qiáng)調(diào)謂語(yǔ)時(shí)，用助動(dòng)詞do/ does或did.如：Do sit down. 務(wù)必請(qǐng)坐。He did write to you last week. 上周他確實(shí)給你寫(xiě)了信。Do be careful when you cross the street. 過(guò)馬路時(shí)，務(wù)必(千萬(wàn))要小心啊!

⒉ 注意：此種強(qiáng)調(diào)只用do/ does和did，沒(méi)有別的形式;過(guò)去時(shí)用did，后面的謂語(yǔ)動(dòng)詞用原形。

⒈ 強(qiáng)調(diào)結(jié)構(gòu)的疑問(wèn)形式：強(qiáng)調(diào)一般疑問(wèn)句中的某一成分時(shí)，要在主句中用一般疑問(wèn)句的順序。

如：Was it you that/who broke the window?

Was it in the war that he lost his son?

⒉ 強(qiáng)調(diào)特殊疑問(wèn)句中的疑問(wèn)詞，其結(jié)構(gòu)模式是：“疑問(wèn)詞+is/was+it +that。”它同感嘆句的強(qiáng)調(diào)模式極其相似，首先將疑問(wèn)句開(kāi)頭的部分作為強(qiáng)調(diào)部分，套入強(qiáng)調(diào)結(jié)構(gòu)，然后再將其變?yōu)橐蓡?wèn)句。

如：Where were you born?

→Where was it that you were born?

What did you want to see?

→What was it that you wanted to see?

How many people are being trained for the special work?

→How many people is it that are being trained for the special work?

⒈ 被強(qiáng)調(diào)的成分為原句的主語(yǔ)時(shí)，that/who之后的謂語(yǔ)動(dòng)詞應(yīng)與被強(qiáng)調(diào)的名詞或代詞在人稱(chēng)和數(shù)方面保持一致關(guān)系，從而選用恰當(dāng)?shù)膭?dòng)詞形式。

如：It is you who/that are wrong.

It is I who/that am answering the question.

⒉ 但是如果被強(qiáng)調(diào)的部分是人稱(chēng)代詞，按理應(yīng)用人稱(chēng)代詞主格形式，但在口語(yǔ)或非正式文體中也可以用其賓格形式，此時(shí)that/who的謂語(yǔ)動(dòng)詞要用單數(shù)第三人稱(chēng)形式is或was。

如：It is me who is being asked the favor.

⒊ 另在Itis/was…，not…that…句型中，其謂語(yǔ)動(dòng)詞應(yīng)與肯定部分的詞保持一致關(guān)系。

如：It is my brother,not I that studies in that school.

It is you,not your sister that are in charge of the company.

既要體現(xiàn)強(qiáng)調(diào)句型的形式特征，又要體現(xiàn)感嘆句的自然語(yǔ)序。

如：How happy he looks!→How happy it is that he looks!

What a clever boy he is!→What a clever boy that he is!
