3、hisC.thatD.itThisisnotmystory,northewholestory.Mystoryplaysoutdifferently.A.isthereB.thereisC.isitD.itisC。此題考查的知識(shí)點(diǎn)是強(qiáng)調(diào)句。notuntil的強(qiáng)調(diào)句型：Itiswasnotuntilthat。故C正確。B。句子開(kāi)頭有Itwas，如果去掉Itwas部分，余下部分是一個(gè)完整句子，判斷這是強(qiáng)調(diào)句型。強(qiáng)調(diào)句的固定結(jié)構(gòu)為Itiswasthatwho，答案為that。句意為：正是在我回家的時(shí)候我才意識(shí)到助人于危難中是多么令人高興的事。D。句意：當(dāng)你正在看一個(gè)你喜歡的節(jié)目時(shí)，突然有個(gè)人進(jìn)來(lái)，一聲
