強(qiáng)調(diào)句型常用句型：It is/was +… who/that…

1. 如強(qiáng)調(diào)句型指現(xiàn)在或未來的情況用It is指過去用It was。

e.g. It is I who/ that am wrong.

分析：被強(qiáng)調(diào)部分為人強(qiáng)調(diào)詞可用who也可用that. 指現(xiàn)在的情況所以以 It is開頭，被強(qiáng)調(diào)部分是 I謂語用 “am”

原句： I am wrong.

e.g. It was him who\that I saw the day before yesterday.

原句為 I saw him the day before yesterday.

分析：指過去的情況用It was 開頭，被強(qiáng)調(diào)部分為人所以強(qiáng)調(diào)詞仍是who\that.

2. 被強(qiáng)調(diào)部分往往為句子的主語、賓語、時(shí)間狀語、地點(diǎn)狀語等，但有時(shí)也可以強(qiáng)調(diào)比較復(fù)雜的內(nèi)容。 如時(shí)間狀語從句、地點(diǎn)狀語從句、not until… 結(jié)構(gòu)、not only…but also…和as well as…等結(jié)構(gòu)。

e.g. It was only when I reread his poems recently that I began to appreciate their beauty. (appreciate means understand and enjoy the good qualities or value of something欣賞、鑒賞、領(lǐng)會(huì))

分析：強(qiáng)調(diào)部分為復(fù)雜的時(shí)間狀語從句強(qiáng)調(diào)詞不能使用when只可用that

e.g.It is not only he but also his parents who\that have been to Beijing.

3. 被強(qiáng)調(diào)部分為人稱代詞時(shí)，原句用什么格強(qiáng)調(diào)句也用什么格。

如上述例句。

4. 關(guān)于強(qiáng)調(diào)詞的選用，強(qiáng)調(diào)人時(shí)可用who 或that，如果不強(qiáng)調(diào)人一律用that。此時(shí)絕不能與定語從句混淆，被強(qiáng)調(diào)部分為時(shí)間狀語、地點(diǎn)狀語、或原因狀語時(shí)不可誤用when, where 或why。

e.g. It was in the street that I met him yesterday.

盡管被強(qiáng)調(diào)部分是地點(diǎn)狀語，強(qiáng)調(diào)詞不能使用where只可用that.

e.g. It was about 600 years ago that the first clock with a face and an hour hand was made.分析：指過去的情況用It was 開頭，盡管被強(qiáng)調(diào)部分是時(shí)間狀語，強(qiáng)調(diào)詞不能使用when只可用that.

e.g. It was because he was ill that died at once

被強(qiáng)調(diào)部分為復(fù)雜的原因狀語從句強(qiáng)調(diào)詞不能使用why只可用that。

5. 被強(qiáng)調(diào)部分如果為主格人稱代詞，who\that后的動(dòng)詞和主格人稱代詞在人稱和數(shù)上保持一致。

6. 強(qiáng)調(diào)句型的一般疑問句結(jié)構(gòu) Is\Was it… who\ that…?

e.g. Was it during the Second World War that he died?

分析：以Was it 開頭被強(qiáng)調(diào)部分是時(shí)間狀語，強(qiáng)調(diào)詞用that。

7. 強(qiáng)調(diào)句型的特殊疑問句結(jié)構(gòu)

特殊疑問詞+is\was it… who\ that…?

強(qiáng)調(diào)句型的特殊疑問句是就特殊疑問詞強(qiáng)調(diào)

Where was it that you found your lost pen?

原句：Where did you found your lost pen?

8.強(qiáng)調(diào)句型It is \was…who/ that中is\was前面可用much\may\might等表推測的情態(tài)動(dòng)詞修飾。

e.g. It might be in his room that he met her.

注意：如改成特殊疑問句由于may,must表推測的情態(tài)動(dòng)詞只用于肯定句，所以否定句，疑問句might 應(yīng)改成could.

e.g. Where could it be that he met her?

9. 強(qiáng)調(diào)部分為時(shí)間狀語和地點(diǎn)狀語時(shí)有可能先接定語從句再接強(qiáng)調(diào)句型。

e.g. It was on October 1st,1949 when he joined the Party that he was killed.

e.g. It was in the room where he had studied for three years that he hound his lost pen.

10. 判斷強(qiáng)調(diào)句型是否正確的方法是將強(qiáng)調(diào)部分去掉如去掉強(qiáng)調(diào)句型結(jié)構(gòu)后句子仍正確，強(qiáng)調(diào)句型就正確。
