一．講練共兩課時
強調(diào)句型使用十要素
It is/was +… who/that…
十要素分別舉例說明：
1. 如強調(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：被強調(diào)部分為人強調(diào)詞可用who也可用that. 指現(xiàn)在的情況所以以 It is開頭，被強調(diào)部分是 I謂語用 “am”
原句： I am wrong.
e.g. It was him who hat 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，被強調(diào)部分為人所以強調(diào)詞仍是who hat.
2. 被強調(diào)部分往往為句子的主語、賓語、時間狀語、地點狀語等，但有時也可以強調(diào)比較復雜的內(nèi)容。 如時間狀語從句、地點狀語從句、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)
分析：強調(diào)部分為復雜的時間狀語從句強調(diào)詞不能使用when只可用that
e.g.It is not only he but also his parents who hat have been to Beijing.
3. 被強調(diào)部分為人稱代詞時，原句用什么格強調(diào)句也用什么格。
如上述例句。
4. 關(guān)于強調(diào)詞的選用，強調(diào)人時可用who 或that，如果不強調(diào)人一律用that。此時絕不能與定語從句混淆，被強調(diào)部分為時間狀語、地點狀語、或原因狀語時不可誤用when, where 或why。
e.g. It was in the street that I met him yesterday.
盡管被強調(diào)部分是地點狀語，強調(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，盡管被強調(diào)部分是時間狀語，強調(diào)詞不能使用when只可用that.
e.g. It was because he was ill that died at once
被強調(diào)部分為復雜的原因狀語從句強調(diào)詞不能使用why只可用that。
5. 被強調(diào)部分如果為主格人稱代詞，who hat后的動詞和主格人稱代詞在人稱和數(shù)上保持一致。 （如例一所示）
6. 強調(diào)句型的一般疑問句結(jié)構(gòu) IsWas it… who that…?
e.g. Was it during the Second World War that he died?
分析：以Was it 開頭被強調(diào)部分是時間狀語，強調(diào)詞用that。
7. 強調(diào)句型的特殊疑問句結(jié)構(gòu)
特殊疑問詞+iswas it… who that…?
強調(diào)句型的特殊疑問句是就特殊疑問詞強調(diào)
Where was it that you found your lost pen?
原句：Where did you found your lost pen?
8．強調(diào)句型It is was…who/ that中iswas前面可用muchmaymight等表推測的情態(tài)動詞修飾。
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)動詞只用于肯定句，所以否定句，疑問句might 應改成could.
e.g. Where could it be that he met her?
9. 強調(diào)部分為時間狀語和地點狀語時有可能先接定語從句再接強調(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. 判斷強調(diào)句型的使用是否正確的方法是將強調(diào)部分去掉如去掉強調(diào)句型結(jié)構(gòu)后句子仍正確，強調(diào)句型就正確。
