②Itwastheexperimentthatmyfatherdidinthelabyesterdayevening.我父親昨晚在實驗室做的是試驗。

③Itwasyesterdayeveningthatmyfatherdidtheexperimentinthelab。是昨天晚上我父親在實驗室做試驗.

④Itwasinthelabthatmyfatherdidtheexperimentyesterdayevening.我父親昨晚是在實驗室做試驗.

通過觀察以上句子,我們發(fā)現(xiàn)：在Itwas和that/who之間插入了單詞或短語，它們分別是原句的四個成分（主語、賓語、時間狀語、地點(diǎn)狀語）,且這四個句子都是(1）________結(jié)構(gòu),我們把它們叫作it的強(qiáng)調(diào)句型。此結(jié)構(gòu)可以強(qiáng)調(diào)除（2)_________以外的所有句子成分。強(qiáng)調(diào)句中的連接詞只用that(指人或物）或who（僅指人),且都不可省略。[具體用法］（一）基本用法1。強(qiáng)調(diào)句的陳述句式“Itis/was+被強(qiáng)調(diào)部分+that/who+剩余部分”ItwasLangLangwhoheldacharityconcertinTaipeilastWednesday.強(qiáng)調(diào)句的一般疑問式“Is/wasit+被強(qiáng)調(diào)部分+that/who+剩余部分”WasitLiPingwho/thathemetyesterday？他昨天遇到的是李萍嗎?強(qiáng)調(diào)句的特殊疑問式“被強(qiáng)調(diào)的特殊疑問詞+is/wasit+that+剩余部分"Howisitthatsheturneddownourhelp？4。not…until的強(qiáng)調(diào)句“Itis/wasnotuntil+被強(qiáng)調(diào)部分+that+剩余部分”ItwasnotuntilhecamebackthatIknewtheresult。（二）強(qiáng)調(diào)句應(yīng)注意的問題強(qiáng)調(diào)句的判斷如果把強(qiáng)調(diào)結(jié)構(gòu)去掉,句子結(jié)構(gòu)完整，那么這個句子就是強(qiáng)調(diào)句。如果去掉了強(qiáng)調(diào)結(jié)構(gòu)，結(jié)構(gòu)不完整,則句子不是強(qiáng)調(diào)句。如：①(Itwas)becausehewasill（that)hecameherelate.（強(qiáng)調(diào)句)②(Itwas)1998（that)shewasborn。(錯;1998前加in構(gòu)成狀語作為被強(qiáng)調(diào)部分）易與強(qiáng)調(diào)句混淆的幾個句式Itis+時間+when…,when引導(dǎo)的是時間狀語從句，主句中的it指時間，表語由具體的時間充當(dāng).Itwasteno’clockwhenwegothomelastnight。（時間狀語從句)Itwasatteno’clockthatwegothomelastnight。（強(qiáng)調(diào)句）itwas/willbe…before…過……就……Itwasnot/willnotbe…before…不久……就……主句中的it指時間，表語多是long，notlong,threedays,twoweeks等表示“一段時間"的詞或短語。ItwasthreedaysbeforehewenttoBeijing.ItwasthreedaysagothathewenttoBeijing.(強(qiáng)調(diào)句型）［用法檢測］（1)Itwas_______backhomeaftertheexperiment.
