44、中不得出现真姓名、地点和学校名称。Saturday, Jun. 8th, 2019SunnyToday I visited the Science Museum and it was really interesting._参考答案I.单项选择。1D【详解】句意：对不起，我们没有你要的外套。考查定语从句。what什么（不用于定语从句）；who代指人，作主宾；whom代指人，作宾；which代指物，作主宾；根据先行词“the coat”，是物，在从句中作“need”的宾语，所以此处是用“which”，故选D。2D【详解】句意：我永远不会忘记我在农场和农民一起生活的那些年，这对我的生活有很大的影响

45、。考查定语从句。根据“those years . I lived on the farm with the farmers”可知这是个限制性定语从句，先行词“those years”表示时间，在从句中作时间状语，用when引导定语从句；再由“has a great effect on my life”可知此处是非限制性定语从句，先行词those years，指时间，在从句中作主语，用which引导定语从句。故选D。3B【详解】试题分析：句意：来这儿的女孩，她的书法在我们班是最好的。谁的用whose。故选B。4A【详解】句意：有许多种污染，例如：空气污染、光污染等等。考查副词短语。for ins

46、tance例如；example例子；however然而；instance实例。由语境可知，air pollution, light pollution and so on是many kinds of pollutions的具体实例，for instance，例如、比如，符合题意。故选A。5B【详解】句意：婴儿应该在家中得到照顾。考查被动语态。主语the baby和谓语动词take care of构成动宾关系，应用被动语态。take care注意、当心，为不及物动词短语，不能用于被动语态，故选 B。6D【详解】句意：哈利波特与魔法石是一本相当不错的书。它值得读。考查非谓语动词。read读，动词原

47、形；reads是动词第三人称单数形式；to read动词不定式；reading动名词或现在分词形式。句中使用了句型be worth doing sth.“值得做某事”，因此这里用动名词形式。故选D。7A【详解】句意：你的汽车不能放在这里，请停到那边。考查情态动词。cant不能；can能，会；may可以；可能；may not不可以，可能不。根据句意“Please put it over there”可知，这里应填否定的意思，排除B和C；结合语境可知，这里的语气比较强，因此cant比较符合，故选A。8B【详解】句意：我喜欢未来在舞台上表演芭蕾。考查介词辨析。on在上面；at在；in在里面；unde

48、r在下面。on the stage“在舞台上”；in the future“在未来”。故选B。9A【详解】句意：你能告诉我一些关于金星的事吗？对不起，我不能。我对它知之甚少。考查代词辨析。little“几乎没有”，修饰不可数名词；a little“一点儿”，修饰不可数名词；few“几乎没有”，修饰复数名词；a few“几个”，修饰复数名词。根据“Sorry, I cant”可知，此处表示否定含义，指“我几乎不了解金星”，故排除B、D项，“与金星有关的信息”为不可数名词，所以用little修饰。故选A。10D【详解】句意：丽丽最近很努力学习英语。是的。她下定决心要提高她的英语。考查名词辨析。id

49、ea主意；thought想法；advice建议；mind思想。根据“Shes made up her.to improve her English.”可知，此处指她下定决心要提高她的英语，短语“make up ones mind to do”“下定决心做”。故选D。11B【详解】句意：中国是一个拥有5000年历史的伟大国家。考查定语从句的引导词。分析句子结构可知，该从句为定语从句，country为先行词，又因先行词为物，故从句引导词应为关系代词that，在从句中作主语。故选B。12B【详解】句意：合肥变得多么美丽啊！是的，毫无疑问合肥很快会发展成为一个现代化的城市。考查名词辨析。challen

50、ge挑战；doubt怀疑；purpose目的；decision决定。根据“Hefei will develop into a modern city soon.”可知合肥会很快发展为一个现代化的城市是毫无疑问的。故选B。13A【详解】句意：在接下来的几年里，一条连接扬州和长江三角洲其他地区的新铁路将建成。考查动词短语。connect连接；connected是其过去式；connects是其三单形式；connecting是其现在分词形式。connectto“把连接到”；connectwith“和有联系”。根据“A new railway will be built toYangzhou”可知，此处

51、指的是建新铁路是为了连接，动词不定式作状语表示目的，to后应接动词原形，第一个空应填connect。故选A。14A【详解】句意：他致力于的研究证明是相当成功的。考查一般过去时。此句为含有定语从句的复合句，其中“he had devoted himself to”是定语从句，修饰先行词“research”；动词prove是主句的谓语动词；根据“had devoted himself to”可知，主句时态为一般过去时，故prove用其过去式。故选A。【点睛】易错分析：此题很容易受“devote oneself to sth.”影响而误选答案D；我们要分析句子结构，复合句的主语是“the resea

52、rch”，接下来就要考虑谓语动词了，proving能单独作谓语吗？如果这样去考虑问题，就不会选D了。15D【详解】句意：学校旅行昨天被取消了。为什么？因为雨下了一整天。考查时态和被动语态。is canceled被取消，一般现在时被动语态，主语为单数；had canceled已经取消，过去完成时；will cancel将取消，一般将来时；was canceled被取消，一般过去时被动语态，主语为单数。根据语境可知，答语为昨天一整天都在下雨，可推测此处是昨天学校旅行被取消了，“The school trip”与“cancel”之间关系为被动，又因yesterday，事情为过去发生的，时态为一般过去

53、时，语态为被动，谓语用“was/were+过去分词”的结构，主语为The school trip，第三人称单数，be动词用was，canceled“取消”为动词过去分词。故选D。II. 完形填空。16B 17C 18A 19C 20B 21C 22C 23A 24B 25C【导语】本文主要介绍了一名著名的设计师和一个大学生发明的一种新水杯。16句意：他们花了好几年的时间。in在里；on在上；at在。spend time on sth.“在某事上花费时间”。故选B。17句意：智能杯不仅能区分可口可乐和百事可乐，还能告诉人们是否应该喝水。and和；though虽然；but但是。not only.b
