8年级英语寒假作业02 情态动词could（can）（巩固培优）（原卷版）

限时练习：40min完成时间：月日天气：寒假作业02情态动词could的用法情态动词could表请求与许可1.核心用法——表委婉请求基本句型：向他人提出礼貌请求时，核心结构为“Couldyou(please)+动词原形+其他？”，语气比“can”更柔和，适用于陌生人、长辈或需要体现礼貌的场景。例如“Couldyoupleasepassmetheplate？”（你能把盘子递给我吗？）、“Couldyouhelpmecarrytheheavybox？”（你能帮我搬这个重箱子吗？）。否定形式：请求对方不要做某事时，需用“Couldyoupleasenot+动词原形+其他？”，如“Couldyoupleasenotmakenoiseintheclassroom？”（你能别在教室里出声吗？）、“Couldyoupleasenotforgettobringyourtextbook？”（你能别忘记带课本吗？）。2.核心用法——表许可与回应请求自己做某事：想获得允许做某事时，用“CouldI+动词原形+其他？”，例如“CouldIuseyourumbrella？”（我能用你的伞吗？）。回应时，同意常用“Sure./Ofcourse./Noproblem.”，拒绝可用“Sorry,youcan’t.”，需注意回应不用“CouldI”，因“could”仅表委婉，不表过去时态。回应他人请求：面对“Couldyou...”的请求，同意用“Certainly./Yes,Ican.”，如对方问“Couldyoupleaseopenthewindow？”（你能开下窗户吗？），可回答“Certainly.”（当然可以）。3.易混辨析——couldvs.can语气差异：“could”更委婉礼貌，适合正式或陌生场景，比如向老师求助说“Couldyoupleasehelpmewithmyhomework？”（您能帮我辅导作业吗？）；“can”较随意，适合熟人场景，如对朋友说“Canyouhelpme？”（你能帮我一下吗？）。用法侧重：“could”仅用于“委婉请求”，不表“能力”；“can”可表“请求”或“能力”，如“Icanswim.”（我会游泳），此处不能用“could”替换。【【易错提醒】1.对提出请求或征询许可的句型做否定回答时，通常以sorry或I’msorry开头。Eg.—CouldyouhelpmewithmyEnglishnow?你现在能帮我学英语吗？—I’msorry,butIhaveafootballmatchtenminuteslater.抱歉，我十分钟后要参加一场足球赛。2.如果问句中使用could，回答时要用can或can’t，不能用could或couldn’t。Eg.—CouldIuseyourbike?我能用一下你的自行车吗？—Sure,youcan.当然可以。三层必刷：巩固提升+能力培优+创新题型一、选择题1．Thecleverboy________recitesomanypoemswhenhewasthree.A．might
