2026年新教材人教版九年级上册英语期末复习 Unit 1-8 单元易错知识点解析+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期末复习Unit1-8单元易错知识点解析+配套练习题Unit1TheChangingWorld【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。

Unit2InspiringPeople【单元话题】榜样人物与时代楷模的品格力量、科学精神与社会担当【语法项目】Itis/was+adj.+of/forsb.todosth.核心句型；形容词-ed与-ing分词辨析；admire/devote等动词固定句型易错点1：Itis+adj.+ofsb.与Itis+adj.+forsb.的介词混用【易错点】分不清何时用of，何时用for。例如把Itiskindforyoutohelpme当成规范表达。【错因分析】介词取决于前面的形容词所修饰的属性：形容词指人性格、品质（kind,polite,brave,clever,honest,wise,generous,careless,cruel等）时用ofsb.，因为此类形容词与人物构成系表关系（如Youarekind）；形容词指客观事物特点或行为难易、必要性（important,necessary,difficult,easy,dangerous,possible等）时用forsb.，此类形容词不能修饰人（不能说Youarenecessary）。【正误对比】

【错例】Itisverybravefortheyoungmantojumpintotherivertosavethechild.→【正例】Itisverybraveoftheyoungmantojumpintotherivertosavethechild.

【错例】Itisnecessaryofallcitizenstoobeytrafficrules.→【正例】Itisnecessaryforallcitizenstoobeytrafficrules.【语法规则】品格性格用of人，人表赞贬理通顺；难易客观用for人，行为性质辨得真。易错点2：it作形式主语时，真实主语的结构残缺或非谓语形式用错【易错点】写成ItisimportantforuslearnEnglish.（漏掉to）或者TolearnEnglishwellitisimportant.（多余it）。【错因分析】it在句中充当形式主语，替代句末真正的主语——动词不定式短语（todosth.）。不可将to丢弃直接跟动词原形，也不可在已置前的不定式后重复加形式主语it。【正误对比】

【错例】Ittakesgreatcouragespeakupforthetruth.→【正例】Ittakesgreatcouragetospeakupforthetruth.

【错例】Toovercomethesedifficultiesitisnoteasyforthem.→【正例】Itisnoteasyforthemtoovercomethesedifficulties.【语法规则】it开头占主位，真正主语后排队；动词必须带上to，不可裸形空落位。易错点3：-ing形容词与-ed形容词的修饰对象倒置【易错点】将inspiring（令人鼓舞的）用于修饰人自身的心理感受，或将inspired（受到鼓舞的）用来修饰事物或讲座。【错因分析】-ing形容词表示事物的内在属性，“令人产生某种情感的”，常修饰事物（如aninspiringspeech,anexcitinggame）；-ed形容词表示主体“自身感到某种情绪的”，通常修饰人或人的表情、眼神、声音等（如Wefeltinspired,aninspiredlook）。【正误对比】

【错例】Hisspeechwassoinspiredthateveryonetooknotescarefully.→【正例】Hisspeechwassoinspiringthateveryonetooknotescarefully.

【错例】Hearingthescientist'sstory,allthestudentsweredeeplyinspiring.→【正例】Hearingthescientist'sstory,allthestudentsweredeeplyinspired.【语法规则】物有属性用-ing，令人产生此特征；人受触动用-ed，感到情绪记在心。易错点4：admire的搭配介词误用与宾语搭配混乱【易错点】把“因某事而钦佩某人”写成admiresb.with/aboutsth.，或将admire误接不定式作宾补（admiresb.todo）。【错因分析】admire为及物动词，其核心搭配是admiresb.for(doing)sth.，介词必须用for，表示钦佩的原因。若直接接某人的品格或成就做宾语，则直接用admirehiscourage/achievements。【正误对比】

【错例】Wealladmirethedoctorwithhisgreatmedicalskills.→【正例】Wealladmirethedoctorforhisgreatmedicalskills.

【错例】Teachersadmirehimtoworkhardundersuchpoorconditions.→【正例】Teachersadmirehimforworkinghardundersuchpoorconditions.【语法规则】钦佩敬仰用admire，介词选用for标原因；赞赏品格直接跟，不可乱套不定式。易错点5：devoteoneselfto/bedevotedto中的to是介词而非不定式【易错点】在devote...to...结构后直接接动词原形（如devotehislifetohelpthepoor）。【错因分析】devoteoneselfto/bedevotedto中的to为介词，后必须接名词、代词或动名词（doing），表示“致力于、投身于某项事业或行动”。初中常见“to为介词”的重要短语必须系统归纳。【正误对比】

【错例】TuYouyoudevotedmostofherlifetofindacureformalaria.→【正例】TuYouyoudevotedmostofherlifetofindingacureformalaria.

【错例】Heisdeeplydevotedtoimproveruraleducation.→【正例】Heisdeeplydevotedtoimprovingruraleducation.【语法规则】投身献身devoteto，介词尾巴要看清；后面千万莫跟原型，动名词doing才是亲。易错点6：courage,brave,bravery等同根词词性转化乱位【易错点】在形容词位置误用名词courage（如Heisacourageboy），或在名词位置误用brave（如Ittakesgreatbrave）。【错因分析】courage是不可数名词（勇气）；brave是形容词（勇敢的）；bravery是名词（勇敢行为）；encourage是动词（鼓励）；encouraging是形容词（令人鼓舞的）。九年级重点考查句式中根据语法功能选用对应词性。【正误对比】

【错例】Thesoldiersshowedgreatbraveduringthefloodrescue.→【正例】Thesoldiersshowedgreatcourage/braveryduringthefloodrescue.

【错例】Itisacouragedecisionfortheyounggirltostudyabroadalone.→【正例】Itisabravedecisionfortheyounggirltostudyabroadalone.【语法规则】名词courage表勇气，动词encourage鼓起劲；形容词brave是勇敢，句中成分定词性。

Unit3SmartLearning【单元话题】数字化学习、科学学习策略与高效思维方法【语法项目】that/if/whether引导的宾语从句；从句陈述语序规则；主从句时态呼应；suggest从句虚拟语气易错点1：宾语从句的语序错误（把疑问语序直接当作从句语序）【易错点】将一般疑问句或特殊疑问句的助动词/系动词前置语序直接套入宾语从句（如Idon'tknowwheredoeshelive）。【错因分析】宾语从句在复合句中充当宾语，属于名词性从句，其本质是一个陈述结构，必须严格采用“引导词+主语+谓语+其他”的陈述语序。无论主句是陈述句还是疑问句，从句内部语序必须始终为陈述语序。【正误对比】

【错例】Couldyoupleasetellmewhenwilltheonlinelecturebegin?→【正例】Couldyoupleasetellmewhentheonlinelecturewillbegin?

【错例】IwonderifisthistabletusefulforEnglishstudy.→【正例】IwonderifthistabletisusefulforEnglishstudy.【语法规则】从句无论主如何，语序必是陈述式；助动be词归原位，主语领先谓语跟。易错点2：that引导的宾语从句中that的用法与省略误区【易错点】误以为that在任何时候都可以省略，或误将what当作that来用。【错因分析】that引导陈述句充当宾语从句时，只起连接作用，在从句中不充当任何句子成分，也无实际意义，单句口语中常可省略。但若主句后跟有两个或两个以上并列的that宾语从句，第一个that可省，第二个及后续的that绝对不能省；此外，that从句前有插入语或介词短语隔离时，that也不可省。而what引导从句时，必须在从句中充当主语、宾语或表语。【正误对比】

【错例】Theteachertoldusweshouldpreviewlessonsandthatwemusttakenotes.(若第二处that漏掉则错)

【错例】Ibelievewhathewillsucceedinthefinalexam.→【正例】Ibelievethathewillsucceedinthefinalexam.【语法规则】that连接不当差，无义成分可省它；并列从句排后座，第二that莫漏下；what指代事与物，主宾表语不能缺。易错点3：if与whether引导宾语从句的选词边界与排他场景【易错点】在只能用whether的特殊语法位置上（如介词后、与ornot紧连、动词不定式前）误用if。【错因分析】if与whether均可引导“是否”含义的宾语从句。但有四种情况只能用whether，绝不可用if：①与ornot直接紧挨连用（whetherornot）；②介词后面作宾语（dependonwhether...）；③后面紧跟动词不定式（whethertodo...）；④引导主语从句、表语从句、同位语从句时。【正误对比】

【错例】Italldependsoniftheweatherwillclearuptomorrow.→【正例】Italldependsonwhethertheweatherwillclearuptomorrow.

【错例】Idon'tknowifornothewillattendtheseminar.→【正例】Idon'tknowwhetherornothewillattendtheseminar.【语法规则】是否若用whether/if，通常情况互替换；介词之后跟不定，紧靠ornot用whether灵。易错点4：主从句时态呼应原则及“客观真理”例外陷阱【易错点】主句是一般过去时，从句误用现在时态；或者从句表达客观真理/科学常识时，受主句过去时影响盲目变为过去时。【错因分析】主句为现在时态（一般现在、现在完成、一般将来），从句按实际需要自选时态；主句为过去时态（一般过去时等），从句必须退回对应的过去时态（一般过去、过去进行、过去完成、过去将来）。极其重要的例外：当从句陈述的是客观真理、科学定律、格言警句、永恒事实时，无论主句是什么时态，从句一律严格使用一般现在时。【正误对比】

【错例】Thephysicsteachertoldusthatsoundtraveledslowerthanlight.→【正例】Thephysicsteachertoldusthatsoundtravelsslowerthanlight.

【错例】HeaskedmeifIwillattendthestudygroupmeeting.→【正例】HeaskedmeifIwouldattendthestudygroupmeeting.【语法规则】主现从随由心意，主过从过时态移；客观真理不受限，一般现在表万机。易错点5：suggest后面接宾语从句的虚拟语气结构【易错点】误把suggest后面套用suggestsb.todosth.，或在suggestthat从句中随意使用过去时。【错因分析】suggest表示“建议”时，不可接sb.todo（表达“建议某人做某事”需用advisesb.todo）。其核心句型为suggestthatsb.(should)dosth.，从句谓语动词必须使用动词原形，should可以省略。注意：suggest表示“表明、暗示”时，从句使用陈述语气正常时态。【正误对比】

【错例】OurEnglishteachersuggestedustomakeflashcards.→【正例】OurEnglishteachersuggestedthatwe(should)makeflashcards./advisedustomakeflashcards.

【错例】HuaLuogengsuggestedthatstudentstooknotescarefully.→【正例】HuaLuogengsuggestedthatstudents(should)takenotescarefully.【语法规则】建议suggest莫接todo，从句should加原形；should省去只留动词根，句法严密方为真。易错点6：宾语从句与“疑问词+不定式”的互化规则与条件限制【易错点】在主从句主语不一致时盲目简化为“疑问词+不定式”，造成逻辑主语混乱；或误用whytodo。【错因分析】只有当宾语从句的主语与主句的主语或宾语保持一致时，从句才可以简化为“疑问词+不定式”。例如Idon'tknowwhatIshouldchoose.→Idon'tknowwhattochoose.但注意：why后面绝不能接不定式，不存在whytodo的形式。【正误对比】

【错例】Myteacheraskedmewhatshouldshedonext.→【正例】Myteacheraskedmewhatsheshoulddonext.

【错例】Idon'tknowwhytodothat.→【正例】Idon'tknowwhyIshoulddothat.【语法规则】主语一致才可缩，疑问词引不定式；what/how/where后加todo，唯独why字不可缩。易错点7：宾语从句否定前移现象及其反义疑问句附加问句的失误【易错点】当主句是Idon'tthink/believe/supposethat...时，误将否定词放在从句中，或在反义疑问句中根据主句主语提问。【错因分析】在think,believe,suppose,expect,imagine等表示认知、信念的动词接that从句时，若从句要表达否定意义，通常将否定词not转移至主句谓语动词前，此为“否定前移”。当该类主从句转化为反义疑问句时，若主句主语是第一人称I/we，简短问句须与从句的主谓保持一致，并注意主句的否定已转移。【正误对比】

【错例】Ithinksmarttoolswillnotreplaceourteachers.(语感欠佳)→【正例】Idon'tthinksmarttoolswillreplaceourteachers.

【错例】Idon'tthinkshehasfinishedthetask,doI?→【正例】Idon'tthinkshehasfinishedthetask,hasshe?【语法规则】think/believe主句居，第一人称否定移；反义疑问看从句，注意主句已含否。

Unit4OurMemory【单元话题】大脑记忆机制、高效遗忘规律对抗与深度思维品质【语法项目】特殊疑问词（what,who,where,when,why,how）引导的宾语从句；非谓语动词remember/forget/regret/stop/try动名词与不定式的辨析易错点1：特殊疑问词作从句主语时的“伪倒装”语序判断【易错点】当特殊疑问词本身充当从句主语时，盲目机械套用“把谓语往后放”导致语序错乱（如Whobrokethewindow?变成Idon'tknowwhodidbreakthewindow）。【错因分析】常规特殊疑问词引导宾语从句时，由于疑问词充当状语或宾语，需采用“疑问词+主语+谓语”。但如果特殊疑问词（who,what,which）本身就在从句中充当主语，其自然语序本身就是陈述语序（主语+谓语），此时切不可插入助动词或倒装。【正误对比】

【错例】Canyoutellmewhatdidhappentoyourmemory?→【正例】Canyoutellmewhathappenedtoyourmemory?

【错例】Iwonderwhodidtakemynotebookaway.→【正例】Iwonderwhotookmynotebookaway.【语法规则】疑问词若作主语，顺序本来就是陈；切忌多心加助动，一气呵成直下行。易错点2：remembertodo与rememberdoing的时间方向混淆【易错点】将remembertodo（记住要做某事）与rememberdoing（记得做过某事）在语境中用反。【错因分析】非谓语动词接todo表达“未来未做的事情”，具有指“向后看、尚未发生”的特征；接doing表达“过去已做的事情”，具有“向前看、已经发生”的特征。同类辨析词包括：forgettodo/forgetdoing；regrettodo/regretdoing；stoptodo/stopdoing；trytodo/trydoing。【正误对比】

【错例】Pleaserememberlockingthedoorbeforeleavingtheclassroom.→【正例】Pleaseremembertolockthedoorbeforeleavingtheclassroom.

【错例】Iremembertomeetherinthelibraryyesterday,butIforgothername.→【正例】Iremembermeetingherinthelibraryyesterday,butIforgothername.【语法规则】todo未做将要做，doing做了已成辙；remembertodo莫忘记，rememberdoing忆前事。易错点3：remindsb.ofsth./remindsb.todosth.搭配界限混淆【易错点】写成TheoldphotoremindsmethatIwasachild（漏介词或从句错位），或写成remindsb.dosth.。【错因分析】remind的核心搭配：①remindsb.ofsth.（使某人想起某事/某人）；②remindsb.todosth.（提醒某人去做某事）；③remindsb.that...（提醒某人……，接宾语从句）。【正误对比】

【错例】Thissongalwaysremindsmemymiddleschoollife.→【正例】Thissongalwaysremindsmeofmymiddleschoollife.

【错例】Pleaseremindhimtakethemedicineontime.→【正例】Pleaseremindhimtotakethemedicineontime.【语法规则】使想起用of牵引，提醒去做todo紧；提醒从句that领，三条结构辨分明。易错点4：memory,memorize,remember,memorial的词形词性混乱【易错点】在动词位置使用名词memory（如Ineedtomemorythesewords），或在形容词位置误用动词。【错因分析】memory为名词，意为“记忆力、记忆”；memorize为及物动词，意为“记住、背诵”；remember为常用动词，意为“记起、牢记”；memorial为名词或形容词，意为“纪念碑、纪念的”。【正误对比】

【错例】Drawingmindmapscanhelpyoumemorykeypointseffectively.→【正例】Drawingmindmapscanhelpyoumemorizekeypointseffectively.

【错例】Ashegrewolder,hismemorizebegantofail.→【正例】Ashegrewolder,hismemorybegantofail.【语法规则】memory脑中记忆在，memorize动词把词背；词性位置对照审，莫让同根串了门。易错点5：宾语从句中what与that的功能混淆【易错点】在从句缺少主语或宾语时误用that，或在从句结构完备时误用what。【错因分析】that是纯连接词，在宾语从句中“不占成分、无具体含义”；what是连接代词，在从句中“必占成分（通常作主语、宾语或表语），意为所……的事物”。【正误对比】

【错例】Weshouldtryourbesttorememberthatourteacherstaughtus.→【正例】Weshouldtryourbesttorememberwhatourteacherstaughtus.

【错例】Thescientistprovedwhatmemorycanbetrainedthroughpractice.→【正例】Thescientistprovedthatmemorycanbetrainedthroughpractice.【语法规则】从句查缺主宾表，缺了就用what补；成分完整无缺失，that引路最称职。易错点6：特殊疑问词+doyouthink插入语的语序陷阱【易错点】写成Doyouthinkwhatcanimproveourmemory?或Whatdoyouthinkcanimproveourmemorydidhappen?【错因分析】当句中含有doyouthink/doyoubelieve/doyousuppose等插入语时，特殊疑问词必须置于句首，后接doyouthink，其后剩余部分恢复陈述语序：特殊疑问词+doyouthink+陈述语序其余部分？【正误对比】

【错例】Doyouthinkwhereshouldwestoretheseimportantmemories?→【正例】Wheredoyouthinkweshouldstoretheseimportantmemories?

【错例】Whodoyouthinkishe?→【正例】Whodoyouthinkheis?【语法规则】think插入语插中间，特殊疑问顶在前；插后句子陈述序，平稳落地画问号。
