1、写作基本句型训练(四)学习内容：强调句型：it+be+强调部分+that+其它Only+状语→引起的倒装until…..notuntil…句型教学步骤：Step1.学习并翻译下面的句子：1.Itwashimthatwemetattheschoolgate.2.OnlyinthiswaycanwelearnEnglishwell.3.Youaretostayhereuntil/tillyourmothercomesback.4.Ididn’tgodownstairsuntilthewindowhadtobeshut.思考：句子①和②分别是什么句式：___

2、_________________,__________________Step2.学习难点：1.Only+状语（副词，介词短语，状从）置于句首引起的倒装OnlyinthiswaycanwelearnEnglishwell.（wecanlearnEnglishwellinthisway）介短OnlythendidIrealizemymistakes.(Irealizemymistakesthen.)副Onlywhenhereturneddidwefindoutthetruth.(whenhereturneddidwefindoutthetruth.)状

3、从（主句倒装从句不倒）注意：①Only+状语（副词，介词短语，状从）置于句首引起的倒装属于部分倒装，即：把句中的助动词、情态动词置于主语的前面，如句①canwe;当原句中没有或你想表达的句子中没有助动词或情态动词时，则需要另添加助动词（do/does/did）来表示倒装，如句②didI，句③didwe.添加的助动词的时态必须与原句的时态保持一致。②only修饰主语时句子不倒装。判断下列句子的正误：1.Onlyafterthewarlearnedhethesadnews.2.Onlyafterthewarhelearnedthesadnews.3.Onl

6、①not…until…句型的前半部分是需要否定形式的（即通过助动词、情态动词：don’t/doesn’t/didn’t/can’t/haven’t/won’t….来否定）所选用的助动词的时态与原句保持一致。②此句型的后半句（从句部分）需要用一般现在时表示将来。Janewon’tgobackhomeuntilshefinishesherhomework.③not…until…句型可以转化为倒装句和强调句1.notuntil放在句首主句要半倒装。2.强调：itis/wasnotuntil+强调部分+that+其它Thevillagersdidn’treal
