(1)強調(diào)句型的基本結(jié)構(gòu)：Itis/was＋被強調(diào)部分＋that/who＋句子其他部分。①Butrulesalonedon’tsecureanorderlysociety.Itisthepeoplewhoobeytherulesthat(who)matter.但是制度本身不能保證一個有序的社會，遵守規(guī)則的人才是重要的。(2)一般疑問句的強調(diào)句型：Is/Wasit＋被強調(diào)部分＋that/who＋句子其他部分？②WasitthreeyearsagothathewenttoAmericaforfurtherstudy?他是三年前去美國深造的嗎？(3)特殊疑問句的強調(diào)句型：疑問詞(被強調(diào)部分)＋is/was＋it＋that＋句子其他部分？③Whenwasitthatyougotpromoted？你是什么時候升職的？(4)not...until...結(jié)構(gòu)的強調(diào)句型：Itis/wasnotuntil...that...④Itwasnotuntilneartheendoftheletterthatshementionedherownplan.直到將近信的結(jié)尾她才提及了自己的計劃。[名師提醒](1)在強調(diào)句型中It本身沒有實際意義，但不能被其他詞代替；被強調(diào)部分可以是主語、賓語和狀語等；被強調(diào)部分指人時，可用that/who，其他情況一律用that。(2)判斷是否是強調(diào)句型的方法：把Itis/was和that去掉，看句子的結(jié)構(gòu)及語意是否完整，若完整，則為強調(diào)句型；若不完整，則不是。[鞏固內(nèi)化]
