新概念英语第一册Lesson 129-130练习题

新概念英语第一册Lesson____重点语法与练习精析各位英语学习者，大家好！今天我们将聚焦《新概念英语》第一册Lesson129至130课的核心内容，通过系统性的练习来巩固所学。这两课的精髓在于情态动词must与can't用于推测的用法，这是日常交流中判断事物可能性的重要表达，掌握它们能让你的语言更具逻辑性和说服力。一、核心语法点回顾在进入练习之前，我们先简要回顾这两课的核心语法，为后续练习打下坚实基础：1.情态动词must表示“肯定推测”*含义：表示说话人对某件事情有相当把握的肯定推测，意为“一定是”、“准是”。*用法：must+动词原形(表示对现在情况的推测)。*例句：Thatmanmustbeournewteacher.(那个男人一定是我们的新老师。)Shemustlivenearby.(她一定住在附近。)2.情态动词can't表示“否定推测”*含义：表示说话人对某件事情有相当把握的否定推测，意为“不可能是”、“一定不是”。*用法：can't+动词原形(表示对现在情况的推测)。*例句：Hecan'tbeadoctor.He'stooyoung.(他不可能是医生，他太年轻了。)Thiscan'tbemybook.Minehasaredcover.(这不可能是我的书，我的书是红色封面的。)3.对过去动作的推测(初步接触)*在这两课中，我们也初步接触了对过去发生动作的推测，通常用musthavedone(一定做过某事)和can'thavedone(不可能做过某事)。不过，此部分在第一册为初步感知，重点仍在对现在状态的推测。4.关键词汇*本课涉及一些描述人或事物特征的形容词，如famous,expensive,cheap,old,young,foreign,local等，这些词汇是进行推测的基础。二、练习题I.词汇与句型转换(VocabularyandSentenceTransformation)1.根据句意及首字母提示完成单词。*Thatcarisveryexpensive.Itm______belongtoarichperson.*Shecan'tbeastudent.Shelookstooo______.*Thisbookisn'tmine.Itm______beJohn's.Hisnameisonit.*Youc______behungrynow.Youhadabiglunchanhourago.*Thepaintingissobeautiful.Itm______bepaintedbyafamousartist.2.句型转换。将下列陈述句改为否定推测句和肯定推测句。*Example:ThisisTom'spen.(肯定推测)ThismustbeTom'spen.(否定推测)Thiscan'tbeMary'spen.*Heisateacher.*肯定推测:_________________________*否定推测:_________________________(假设我们知道他不是医生)*TheyarefromAmerica.*肯定推测:_________________________*否定推测:_________________________(假设他们说中文)II.语法专项练习(GrammarFocusExercises)1.用must或can't填空。*Lookatthatman!He'swearingapoliceuniform.He______beapoliceman.*Thishouseisveryold.It______bebuiltlastyear.*ShespeaksFrenchfluently.She______befromFranceorBelgium.*Theroomisdark.They______beathome.*Hefailedtheexam.He______havestudiedhard.(对过去的否定推测)*Shegotaperfectscore.She______havestudiedveryhard.(对过去的肯定推测)2.选择填空。*A:Whoseumbrellaisthis?B:I'mnotsure.It______beLucy's.Sheoftenforgetshers.A.mustB.can'tC.should*A:IsthatMr.Smith?B:No,it______behim.HehasgonetoLondon.A.mustB.can'tC.may*Thebabyiscrying.She______behungry.A.mustB.can'tC.needn't3.根据图片提示或上下文完成句子，使用must或can't。*(图片：一个人穿着泳衣，站在游泳池边)He______begoingswimming.*A:Isawamanrunningoutofthebankjustnow.B:He______beathief!*Thiscaketastesterrible.You______haveputtoomuchsaltinit.阅读下面短文，然后根据短文内容用must或can't回答问题。Maryfoundahandbagonthestreet.Inside,therewasadriver'slicense,somemoney,andasmallnotebook.Thedriver'slicenseshowsawomannamed"LindaWang",whowasbornin1985.Thenotebookhassomenotesaboutteachingplans.1.Whodoesthehandbagbelongto?2.WhatmightLindaWang'sjobbe?3.Canthehandbagbelongtoateenager?Why?情景反应：根据所给情景，用must或can't进行合理推测。1.Youseeapersoncarryingaladderandsomepaintbrushes.Whatmighttheybe?_________________________________________________________2.Yourfriendhasahighfeverandislyinginbed.Howdoyouthinkhefeels?_________________________________________________________(提示：He______feelwell.)_________________________________________________________三、参考答案与解析I.词汇与句型转换1.must,old,must,can't,must2.Hemustbeateacher.Hecan'tbeadoctor.TheymustbefromAmerica.Theycan'tbefromChina.(或其他说中文的国家)II.语法专项练习1.must,can't,must,can't,can't,must2.A(must),B(can't),A(must)3.must,must,mustIII.阅读理解与情景反应阅读理解：1.ItmustbelongtoLindaWang.(因为里面有她的驾照。)2.Shemustbeateacher.(因为笔记本里有教学计划。)3.No,itcan't.BecauseLindaWangwasbornin1985,sosheisnotateenager.(或Shecan'tbeateenager.Theownerwasbornin1985.)情景反应：(以下为参考答案，合理推测即可)1.Hemustbeapainter/decorator.2.Hecan'tfeelwell.3.Shemustbecookingsomething/Shemustbedroppingsomething.四、学习建议与拓展1.活学活用：must和can't是表达推测时非常实用的词。在日常生活中，看到不熟悉的人或事物时，不妨尝试用它们进行推测，比如"Themanwithacameramustbeatourist."2.对比记忆：牢记must表示“一定是”（肯定推测），can't表示“不可能是”（否定推测）。可以通过列表或例句对比加深印象。3.听力辅助：回顾Lesson____的课文录音，注意体会说话人在使用
