②Itwastheexperimentthatmyfatherdidinthelabyesterdayevening.我父亲昨晚在实验室做的是试验。

③Itwasyesterdayeveningthatmyfatherdidtheexperimentinthelab。是昨天晚上我父亲在实验室做试验.

④Itwasinthelabthatmyfatherdidtheexperimentyesterdayevening.我父亲昨晚是在实验室做试验.

通过观察以上句子,我们发现：在Itwas和that/who之间插入了单词或短语，它们分别是原句的四个成分（主语、宾语、时间状语、地点状语）,且这四个句子都是(1）________结构,我们把它们叫作it的强调句型。此结构可以强调除（2)_________以外的所有句子成分。强调句中的连接词只用that(指人或物）或who（仅指人),且都不可省略。[具体用法］（一）基本用法1。强调句的陈述句式“Itis/was+被强调部分+that/who+剩余部分”ItwasLangLangwhoheldacharityconcertinTaipeilastWednesday.强调句的一般疑问式“Is/wasit+被强调部分+that/who+剩余部分”WasitLiPingwho/thathemetyesterday？他昨天遇到的是李萍吗?强调句的特殊疑问式“被强调的特殊疑问词+is/wasit+that+剩余部分"Howisitthatsheturneddownourhelp？4。not…until的强调句“Itis/wasnotuntil+被强调部分+that+剩余部分”ItwasnotuntilhecamebackthatIknewtheresult。（二）强调句应注意的问题强调句的判断如果把强调结构去掉,句子结构完整，那么这个句子就是强调句。如果去掉了强调结构，结构不完整,则句子不是强调句。如：①(Itwas)becausehewasill（that)hecameherelate.（强调句)②(Itwas)1998（that)shewasborn。(错;1998前加in构成状语作为被强调部分）易与强调句混淆的几个句式Itis+时间+when…,when引导的是时间状语从句，主句中的it指时间，表语由具体的时间充当.Itwasteno’clockwhenwegothomelastnight。（时间状语从句)Itwasatteno’clockthatwegothomelastnight。（强调句）itwas/willbe…before…过……就……Itwasnot/willnotbe…before…不久……就……主句中的it指时间，表语多是long，notlong,threedays,twoweeks等表示“一段时间"的词或短语。ItwasthreedaysbeforehewenttoBeijing.ItwasthreedaysagothathewenttoBeijing.(强调句型）［用法检测］（1)Itwas_______backhomeaftertheexperiment.
