2026年新教材人教版九年级上册英语Unit 1 The Changing World易错知识点解析+配套练习题（含答案解析）

第第页2026年新教材人教版九年级上册英语Unit1TheChangingWorld易错知识点解析+配套练习题【单元话题】世界与家乡的变迁、发展历程与生态环境【语法项目】一般过去时vs现在完成时的深层辨析；延续性与瞬间性动词转换；usedto句型体系易错点1：一般过去时与现在完成时的语义界限与标志词误判【易错点】混淆“过去动作的影响存在于现在”与“纯粹过去发生事实”。看到句中有过去时间词（如ago,in2020）却误用现在完成时，或看到overthepastfewyears,sofar误用一般过去时。【错因分析】现在完成时本质是“立足现在看过去”，核心在于过去的动作与现在有联系（结果、影响或延续）；而一般过去时本质是“完全属于过去的时间断层”，动作发生在过去某一确切时刻，与现在无直接挂钩。【正误对比】

【错例】IhavevisitedBeijingthreeyearsago.→【正例】IvisitedBeijingthreeyearsago.【错例】Greatchangestookplaceinmyhometowninthelasttenyears.→【正例】Greatchangeshavetakenplaceinmyhometowninthelasttenyears.【语法规则】时间状语定乾坤：yesterday,lastweek,...ago紧跟过去时；sofar,already,yet,over/inthepast...必配完成时；两句合一时，看动作是否“延续或影响至今”。易错点2：非延续性动词在含有for/since时间段句子中的“非法借用”【易错点】直接将瞬间动词（如borrow,buy,die,leave,join,open等）与表示持续的时间段（for.../since...）连用。【错因分析】瞬间动词动作发生瞬间即告终结，无法在时间轴上持续拉长。汉语中“买了三年”、“离开两天”、“死了五年”在语义上是说状态的持续，但英语必须将其转变为“延续性状态”。【正误对比】

【错例】Hehasboughtthecarfortwoyears.→【正例】Hehashadthecarfortwoyears.

【错例】Hisgrandpahasdiedforfiveyears.→【正例】Hisgrandpahasbeendeadforfiveyears./Itisfiveyearssincehisgrandpadied.【语法规则】借变保有(borrow->keep)，买变拥有(buy->have)；来去变在(come/go->behere/there)，离去变离开(leave->beaway)；死变死去状(die->bedead)，入伍入社在其中(join->bein/beamemberof)；开门关门状态现(open/close->beopen/closed)。易错点3：usedtodo/beusedtodoing/beusedtodo/beusedfordoing结构【易错点】将四种结构中的used词性与to的性质（介词还是不定式）混为一谈，特别是将beusedtodoing中的to当作不定式符号后接动词原形。【错因分析】usedtodosth.中usedto为情态动词，后接动词原形表示“过去常常”；beusedtodoingsth.中used为形容词，to为介词，后接动名词表示“习惯于”；beusedtodosth.为use的被动语态，表示“被用来做...”；beusedfordoingsth.同样表示“被用来...”。【正误对比】

【错例】Heisusedtoliveinthecountrysidenow.→【正例】Heisusedtolivinginthecountrysidenow.

【错例】Theknifeisusedtocuttingbread.→【正例】Theknifeisusedtocutbread./Theknifeisusedforcuttingbread.【语法规则】情态过去常常做(usedtodo)；习惯养成介词to后跟doing(beusedtodoing)；被动语态被用来，不定式todo或fordoing紧相连。易错点4：since从句的时态搭配与“Itis+时间段+since...”句型的倒错【易错点】since引导的时间状语从句误用现在完成时；或在“Itis/hasbeen+一段时间+since从句”中错用时态。【错因分析】since引导的时间状语从句本身充当一个“时间起点”，起点必然发生在过去，因此since从句的谓语动词必须用一般过去时，主句才用现在完成时。【正误对比】

【错例】Wehavebeenfriendssincewehaveknowneachother.→【正例】Wehavebeenfriendssincewekneweachother.

【错例】Itwasthreeyearssinceheleftschool.(语义错误)→【正例】Itis/hasbeenthreeyearssinceheleftschool.【语法规则】since后面跟过去，主句完成莫迟疑；Itis时间since过，转眼几年已过去。易错点5：不及物动词短语takeplace/happen/breakout的“被动语态陷阱”【易错点】看到主语是“事物、变化、灾害、事故”等被承受对象，盲目使用被动语态（如changesweretakenplace）。【错因分析】takeplace（发生，按计划）、happen（发生，偶然）、breakout（爆发）都是不及物动词或短语，根本没有及物动词的受词对象，因此绝无被动语态。【正误对比】

【错例】Greatchangesweretakenplaceinthetown.→【正例】Greatchangeshavetakenplaceinthetown.

【错例】Anaccidentwashappenedyesterday.→【正例】Anaccidenthappenedyesterday.【语法规则】发生爆发不及物，切莫套用被动语；takeplace与happen，主动形式表发生。易错点6：havebeento/havegoneto/havebeenin的语境混淆【易错点】在询问人在哪里或陈述人不在现场时误用havebeento；在表达在某地待了多久时误用havegoneto。【错因分析】havebeento侧重“经历”，人已经回到原地；havegoneto侧重“去向”，人正在途中或已到目的地，尚未返回，绝不可用于第一、二人称的陈述句；havebeenin侧重“在某地停留持续的时间”，后常接for/since时间段。【正误对比】

【错例】—Whereisyourfather?—HehasbeentoShanghai.→【正例】—Whereisyourfather?—HehasgonetoShanghai.

【错例】IhavebeeninBeijingtwice.→【正例】IhavebeentoBeijingtwice.【语法规则】beento去过已回来，goneto去了还未归；beenin待在某地久，时间段后常相依。易错点7：although/though与but的成对使用（思维迁移）【易错点】受到母语“虽然……但是……”并列关联词思维影响，在英文主从复合句中同时使用Although和but。【错因分析】英语复合句结构讲究“主从分明，一个连词控两句”。although/though为从属连词，引导让步状语从句；but为并列连词，连接两个并列分句。二者只能择一使用。【正误对比】

【错例】Althoughtheroadisnarrow,butwecanstilldrivethrough.→【正例】Althoughtheroadisnarrow,wecanstilldrivethrough./Theroadisnarrow,butwecanstilldrivethrough.【语法规则】英语连词单兵行，虽然但是不同乘；有了although别加but，保留一个句意清。易错点8：nowthat与since引导原因状语从句的误用与语序混乱【易错点】新教材中出现nowthat（既然，由于），常与since/because混淆，且在主从句语序上颠倒。【错因分析】nowthat表示“既然已成事实”，侧重现实情况变化带来的必然结果；because强调直接因果关系；since侧重显而易见的原因。nowthat常位于句首。【正误对比】

【错例】Becauseyouhavegrownup,youshouldbeindependent.(语气不够贴切)→【正例】Nowthatyouhavegrownup,youshouldlearntotakecareofyourself.【语法规则】既然现在情况变，nowthat开门把理现；由于客观事实在，从句在前主在后。
