八年级英语下册Unit4Whydontyoutalktoyourparents第三课时Section

第三课时SectionA(GrammarFocus～4c)单元语法精讲精练提建议句型向他人提建议的表达方式：①直接建议法：“Let's＋动词原形”表示“我们一起做某事吧”。②委婉建议法：“Shallwe＋动词原形？”表示“我们做某事好吗？”。“Wouldyoumind(not)＋动名词？”表示“你介意(不)做某事吗？/你(不要)做某事好吗？”。③征求性建议法：“How/Whatabout＋名词、代词或动名词？”表示“做某事怎么样？”④劝告性建议法：You'dbetterdo/notdosth.表示“你最好做/不要做某事”。⑤责备性建议法：“Whydon'tyou/Whynot＋动词原形？”表示“你为什么不做某事呢？”连词until，sothat，although(1)until引导时间状语从句，用于肯定句中，意为“直到……时，到……为止”，后跟一个具体的时间点。此时谓语动词只能是延续性动词，表示这一动作或状态延续到until所表示的时间为止。【拓展】until用于否定句中，即not…until…，意为“直到……才……”，表示主语的动作在某一时刻或某一动作之前未发生。此时谓语动词是短暂性动词，如come，go，leave，arrive，buy，borrow等。eg：Ididn'tfinishmyhomeworkuntil10o'clocklastnight.【注意】当until引导的时间状语从句中，主句是一般将来时态时，until从句用一般现在时。(2)sothat既可以引导目的状语从句，也可以引导结果状语从句。*结果状语从句表示的是已经取得的结果。*目的状语从句表示的是想实现的结果。eg：You'dbetterspeakaloudsothatwecanhearyou.(3)although连词，与though同义，用来引导让步状语从句。句中用了连词although或though，就不能再同时使用连词but，但可以与yet，still连用。eg：Although/Thoughhehasalotofmoney，yet/stillheisunhappy.一、单项选择。1．—Whynottotheparknow?—Goodidea！Let'sgo.(2015，湛江)A．goB．togoC．goesD．going2．—Howabouthavingapicnicwithmethisweekend?—．(2015，泉州)A．GoodideaB．HereyouareC．Sorrytohearthat3．—Whataboutarest?—Let'sgoforawalk.(2015，邵阳)A．totakeB．takeC．takingAAC4．Youlooktootired.Whynotarest？(2015，益阳)A．stoptohaveB．tostophavingC．stophaving5．—It'stoocoldtoday.(2015，广西)—Yes.putonyourcoat?A．WhataboutB．Whydon'tC．WhynotD．Let's6．Ihadtoomuchworktodolastnight.Ididn'tgotobed11o'clock.(2015，益阳)A．inB．untilC．forACB7．—Hey，man.Youcan'tcrossthestreetnow.Youhavetowaitthetrafficturnsgreen.—Oh，sorryandthankyou.(2015，丽水)A．whenB．afterC．untilD．while8．—Look！Somepeoplearerunningtheredlights.—Weshouldwaitothersarebreakingtherule.(2015，宁波)A．ifB．unlessC．althoughD．because9．Itisn‘twarmtoday，thesunisshining.(2015，嘉兴)A．orB．andC．becauseD．although10．—Susan，whataretheadvantagesofMP5players?—Mom，theyaresmallerandlightertheycanbecarriedveryeasily.(2015，海南)A．unlessB．ifC．untilD．sothatCCDD二、用方框中的连词填空。although，sothat，until11．Mr.Greenspeaksveryloudlyallthepeoplecanhearhimclearly.12．You'dbettertakethemapwithyouyouwon'tgetlost.13．theyareverytired，theyfeelhappybecausethey'vefinallyfinishedtheirproject.14．Wedidn'tstartourdiscussioneverybodyarrived.15．Thebusdriveralwayssaystous，“Don'tgetoffthebusstops.”sothatsothatAlthoughuntiluntil
