Grammar强调句型TranslatethefollowingintoEnglishorally,payingattentiontheusageofit:1.ItwasnotuntilyesterdaythatImetmyoldfriend.2.Itisinasmallfactorythatmybrotherisgoingtowork.3.Itisasmallfactorywheremybrotherisgoingtowork.4.ItisfivemonthssinceIarrivedinNewYork.5.Wasitinthestreetthatyoumether?6.Whowasitthatcalledhim“comrade”?Grammar强调句型Itis/was+强调部分+that/who/whom+其他成分这个句型用来强调除谓语以外的各种句子成分,被强调部分必须放在itis/was后面，如果强调的部分是人，可以who/whom来代替that.需要注意的是：1.在此结构中,be动词必须是单数，因为主语是it.连接词必须是that（指人时也可以是who/whom)2.主谓一致,在强调句型中，被强调部分作主语时，其形式必须与谓语动词在人称和数上保持一致。3.人称照应：在强调句型中，若强调主语，代词用主格，若强调宾语，代词用宾格。eg:⑴Itwasnotuntilhisfathercamethattheboybegantodohishomework.⑵Itwasnotuntil12o’clockthathearrivedhome.⑶Itwasbecausehewascarelessthathelosthisjob.Itwasbecauseofhiscarelessnessthathelosthisjob.⑷Itwasat7:00a.mthattheplanetookoff.⑸Itwasforthreedaysthathestayedhere.7.通常判断是否是强调句的标志是：把强调结构“itis/was+---+that去掉，若句子仍然成立，就是强调句，否则不是.eg:⑴ItisthetruethatheoncewenttoAmerica.（不是强调句型）⑵Itwasat8o’clockthathecameback.8.It引导的强调句不能用来强调条件状语从句和让步状语从句，可强调because引导的原因状语从句，却不能强调as/since引导的原因状语从句，可强调sothat引导的目的状语从句,却不能强调sothat引导的结果状语从句。Practice1.ThebiggestproblemofChinesefarmersistheshortageofarableland.ItistheshortageofarablelandthatisthebiggestproblemforChinesefarmers.2.Theplantgrowningreenhousesareprotectedfromthewind,rainandinsects.Itistheplantsgrowningreenhousesthatareprotectedfromthewind,rainandinsects.3.Futureagriculturesshoulddependonhightechnologyaswellastraditionalmethods.Itishightechnologyaswellastraditionalmethodsthatfutureagricultureshoulddependon.II.Rewritethesentencesbelow,emphasizingasmanypartsaspossible.1).SomepeopleinSouthAmericastillpractisethiskindoffarming.ItisinsouthAmericathatsomepeoplestillpractisethiskindoffarming.ItissomepeopleinSouthAmericawhostillpractisethiskindoffarming.ItisthiskindoffarmingthatsomepeopleinsouthAmericastillpractise.2).Duringthatperiodoftimetheymadethreeimportantdiscoveries.Itwasduringthatperiodoftimethattheymadethreeimportantdiscoveries.Itwasthreeimportantdiscoveriesthattheymadeduri
