7、型用來強調(diào)除謂語以外的各種句子成分，被強調(diào)部分必須放在it is/was后面，如果強調(diào)的部分是人，可以 who/whom 來代替that. “It ”引導(dǎo)句子無實際意義。)3. To drill the grammar rulesTranslate :杰克昨天在公園遇到你的妹妹。? Jack met your sister in the park yesterday. ( ask students to analyses the sentence)Task1:強調(diào)主語：強調(diào)賓語：強調(diào)地點狀語：強調(diào)時間狀語：4. To sum up key points(1) .在此結(jié)構(gòu)中，be動詞必須是單數(shù)，

8、因為主語是 it ；而且時態(tài) 必須與原句時態(tài)一致；連接詞必須是 that (指人時也可以是 who/ whom)(2) .主謂一致，在強調(diào)句型中，被強調(diào)部分作主語時，that引導(dǎo)剩余部分謂語動詞在人稱和數(shù)上必須與主語保持一致。E g: It is your father that/whom is wrong this time.It is John and his parents that/who have come to China.(3) .人稱照應(yīng)：在強調(diào)句型中，若強調(diào)主語，代詞用主格，若強調(diào)賓語，代詞用賓格。E g: It is they who will attend the wed

10、k yesterday.It was in the park that Jack met your sister yesterday .It was yesterday that Jack met your sister in the park.(5)如何判斷強調(diào)句型？e g: (1) It is the true that he once went to America. It was at 8 o ' clock that he came back.通常判斷是否是強調(diào)句的標(biāo)志是：把強調(diào)結(jié)構(gòu)“it is /was+-+that 去掉，若句子仍然成立，就是強調(diào)句，否則不是 .(6) .

11、常見固定句型：It was not until+時間狀語/狀語從句+that(not和until一起強調(diào))It was because + 從句 +that+It was because of + 名詞 +that +It was + 介詞+時間點/時間段+that+-E g: It was not until his father came that the boy began to do his homework.It was not until 12 o ' clock that he arrived home.It was because he was careless tha

12、t he lost his job.It was because of his carelessness that he lost his job.It was at 7:00 am that the plane took off.It was for three days that he stayed here. It引導(dǎo)的強調(diào)句不能用來強調(diào)條件狀語從句和讓步狀語從句， 可強調(diào)because引導(dǎo)的原因狀語從句，卻不能強調(diào)as/since引導(dǎo)的 原因狀語從句，可強調(diào)so that引導(dǎo)的目的狀語從句，卻不能強調(diào)so that引導(dǎo)的結(jié)果狀語從句。Step3.Do exercise1.
