参考答案一、单项选择（共10小题，满分20分）1、A【解析】【详解】句意：——我在学习英语方面遇到了一些困难。你能给我一些建议吗？——当然。你可以通过大量阅读来提高你的英语水平。考查动名词的用法。havetrouble(in)doingsth.“做某事有困难”，动名词形式作介词in的宾语，in可省略。故选A。2、C【解析】【详解】句意：——莉莉，你能告诉我时装秀什么时候开始吗？——当然。明天上午十点开始。考查宾语从句。宾语从句为陈述语序，故排除选项B；又因为答语“Itwillstartattentomorrowmorning.”为时间，所以此处应为询问时装秀时间，故选C。3、C【解析】【详解】句意：——这个盒子如此重以致于这个老年人搬不动。——我们应该帮助他。考查副词辨析。such如此，用法为such+a/an+adj.+n.+that从句；very很，非常，后接形容词或副词，不接从句；so如此，so+adj./adv.+that从句，表示“如此……以致于”。根据“...heavythattheoldmancan’tcarryit.”可知空格后形容词，且后接了that从句。空处应填so，故选C。4、C【解析】【详解】句意：萨莉正在做饭时听到门铃响了。考查连词辨析。after在之后；since自从；while当……时；before在之前。根据“Sallyheardthedoorbellring…shewascooking”可知，此处强调“做饭”和“门铃响”这两个动作同时发生，用while引导时间状语从句，故选C。5、D【解析】【详解】句意：——刚才你为什么不接我的电话？——当你打电话时我正在洗澡。考查过去进行时。take一般现在时；willtake一般将来时；amtaking现在进行时；wastaking过去进行时。根据“whenyoucalled”可知，空处句子时态应是过去的时态，且表示“自己过去那个时刻正在洗澡”，符合过去进行时。故选D。6、A【解析】【详解】句意：——汤姆明天能来参加我的生日聚会吗？——我不确定。如果他来这里，他会为你准备一些礼物。考查时态。句子是if引导的条件状语从句，遵循主将从现，主句用一般将来时willdo，从句用一般现在时，从句主语是he，从句谓语动词用单三。故选A。7、A【解析】【详解】句意：你可以在你喜欢的任何时候去新加坡——春天、夏天、秋天或冬天。考查连词辨析。whenever任何时间；whatever无论什么；however不管怎样；wherever任何地方。根据题中“spring,summer,autumnorwinter”（春天、夏天、秋天或冬天），指的是“时间”，可知空处应填“whenever”，故选A。8、A【解析】【详解】句意：房子前面过去有一条河，但现在政府把它变成了农田。考查used短语和therebe句型。usedtodo过去（常常）做；beusedtodo被用来做。根据“butnow”可知，空处表示过去的情况，排除C和D；therebe表示“有”，不和have“有”连用，排除B；thereusedtobe“过去有”符合语境和语法。故选A。9、A【解析】【详解】句意：——你们学校的学生人数是多少？——大约两千。他们中的许多人来自农村。考查主谓一致。第一句话中的主语是thenumberof…表示“……的数量”，谓语动词用单数；第二句话中主语是anumberof...表示“许多……”，谓语动词用复数。故选A。10、D【解析】【详解】句意：——医生们成功地挽救了病人吗？——是的。6月2日早晨他动了手术，现在他已脱离危险。考查一般过去时的被动语态。he与动词operate之间是被动的关系，因此要用被动语态，排除BC；operateonsb“为某人做手术”，on不能省略；而题干的on是时间介词。故选D。二、完成句子（共5小题，满分10分）11、similar【解析】【详解】句意：他的教学风格与大多数教师的教学风格相似。similar“类似的”，besimilarto“与……类似”。故填similar。12、Ihavebeentheretwice【解析】【详解】根据所给标点符号可知，本句是陈述句。I作主语；havebeen作谓语；there和twice作状语。故填Ihavebeentheretwice“我去过那里两次”。13、(h)erself【解析】【详解】句意：小女孩仅仅7岁，但是她能自己写信。根据前后表示转折，虽然只有七岁，但是自己能写信。考查短语“byoneself”独自，由于主语是“she”，所以反身代词是herself。故填(h)erself。14、①.in②.need【解析】【详解】inneed“有需要的”,是介词短语,修饰名词people,作定语。故答案为in;need。15、Idisagreewithyou.【解析】【详解】此处可表达为“我不同意你的观点”，句子用一般现在时，主语是I，谓语动词用原形；disagreewithsb.“不同意某人的看法”。故填Idisagreewithyou.三、补全对话（10分）16、1.Whatwereyoudoing2.What’sthebiggestmuseumintheworld3.Haveyoueverbeenthere4.Let’sgotherethisweekend【解析】【导语】本文是海伦和弗兰克之间的对话，两人在谈论一些博物馆，并相约周末去临沂博物馆。【1题详解】根据“Iwasreadingabook.”可知，海伦询问弗兰克昨晚八点正在做什么，应用what提问，时态过去进行时。故Whatwereyoudoing“你正在做什么”符合语境。故填Whatwereyoudoing。【2题详解】根据“TheLouvreMuseum(卢浮宫)inFranceisthebiggestmuseumintheworld.”可知，此处询问世界上最大的博物馆是什么。故What’sthebiggestmuseumintheworld“世界上最大的博物馆是什么”符合语境。故填What’sthebiggestmuseumintheworld。【3题详解】根据“IknowLinyiMuseumisthebiggestmuseuminLinyi”及“No,Ihaven’t.ButIwonderwhatit’slike.”可知，此处询问对方是否去过临沂博物馆，一般疑问句，且为现在完成时。故Haveyoueverbeenthere“你曾经去过那吗”符合语境。故填Haveyoueverbeenthere。【4题详解】根据“Thisweekend?Thatsoundsgreat.”可知，此处提议这个周末去临沂博物馆。故Let’sgotherethisweekend“这个周末我们去那里吧”符合语境。故填Let’sgotherethisweekend。四、阅读理解（40分）17、1.D2.D【解析】【导语】本文主要介绍了中国最伟大的数学家之一——祖冲之和他的成就。【1题详解】代词指代题。分析“Healsoinventedalong-distanceboat.Itwasreallygreatanditcouldtravelover50kilometersaday.”可知，他还发明了一艘长途船，它真的很棒一天可以行驶50多公里。所以It指的是长途船，故选D。【2题详解】推理判断题。根据“Inmemoryofthisgreatancientscientist,TsuChungChi(祖冲之环形山)isnamedafterhimonthemoon.”可知，为了纪念这位伟大的古代科学家，月球上的祖冲之环形山以他的名字命名。所以月球上的祖冲之环形山不是他的成就。故选D。18、6.A7.C8.B9.B10.D【解析】【导语】本文主要讲述了两个好朋友在公司受到了不公平的待遇，其中一个人想辞职，老板为了留着这个人，通过买西瓜的事情让他明白两个人之间的差距。【6题详解】细节理解题。根据“Tomcouldn’tstandit,sohehandedalettertohisboss,sayingthathedecidedtoresign（辞职）hisjobbecausethebossdidn’tvaluehishardworkatall”可知，看到Mike升职了，Tom很生气，决定辞职，故选A。【7题详解】细节理解题。根据“sayingthathedecidedtoresign（辞职）hisjobbecausethebossdidn’tvaluehishardworkatall”可知，认为老板不公平，所以决定辞职，故选C。【8题详解】细节理解题。根据“Ihopeyouwilldoonemorethingforourcompanybeforeyouleave”可知，希望离开前多做一件事情，故选B。【9题详解】推理判断题。根据“TomgottoknowthedifferencebetweenMikeandhimself.Hedecidednottoresignhisjobanymore”可知，是为了让Tom明白他和Mike之间的区别，让他明白为什么Mike能升职，故选B。【10题详解】推理判断题。通读全文可知，Tom起初因为好朋友Mike升职而感到生气，后来看到Mike为工作所付出的努力，明白成功都是需要努力和深思熟虑的，故选D。19、1.C2.B3.A4.A5.D【解析】【导语】本文作者讲述了自己对音乐的热爱，虽然失去了双手，但演奏乐器给自己的生活带来了快乐。【1题详解】细节理解题。根据“Allofthesemightnotseemlikeabigdealformanychildrenbutasforme,therewassomethingdifferent.MyhandswerehurtwhenIwasaboutoneyearold.”可知Laura认为自己不同于别人是因为她的手有问题。故选C。【2题详解】词义猜测题。根据“However,musicgivesmestrength.OnceIwassoupsetthatIdidn’tevenwanttogetoutofbed.ThenasongcameoutoftheTV.Igotupandstarteddancing.Ithelpedmesaytomyself.‘Cheerup!Icangetthroughthehardtime.’”可知失落的时候音乐使作者振奋起来，由此推出音乐给作者了力量，strength意为“力量”。故选B。【3题详解】细节理解题。根据“WhenI’mwithothermembersoftheband.theydon’ttreatmedifferently.Wepracticehappilyeveryday.”可知和其他成员待在一起的时候，Laura感觉很高兴。故选A。【4题详解】细节理解题。通读全文内容可知Laura双手有问题，但她没有放弃，凭着对音乐的喜爱，坚持不懈，加入了学校乐队，由此推出我们可以学到：永不放弃。故选A。【5题详解】标题归纳题。本文作者讲述了自己对音乐的热爱，虽然失去了双手，但演奏乐器给自己的生活带来了快乐。用“AGirl’sLoveforMusic”做标题最合适。故选D。20、1.B2.C3.D4.A【解析】【导语】本文主要介绍了作者手机上的几个让他生活更容易的应用程序。【1题详解】细节理解题。根据“Theapps(用程)onmyphonehelpmehaveaneasylife.”可知，我手机上的应用程序帮助我过着轻松的生活。由此可知，这篇文章主要讲一些应用程序。故选B。【2题详解】细节理解题。根据表格一中的时间安排“9：00a.m.:Runintheparkforexercise”可知，作者上午9点开始锻炼。故选C。【3题详解】细节理解题。根据表格一中的描述“Thereisalsoamapontheapp.”可知，应用程序上除了天气预报，还有一张地图。故选D。【4题详解】
