参考答案

1.B迈克的英语老师订阅了一份日报和一份周刊杂志。

［考点］词义辨析

【精析】Bprescribe:规定,开处方；subscribe:订阅，订购，一般与介词to连用;describe:描述；transcribe:抄写,誊写。根据句意可知，选B

2.D女士们，先生们！很荣幸向你们所有人介绍我们的新经理李先生。

［考点］非谓语动词

【精析】D分析句子结构可知，这里考查的是Itis+adj./n.+todo结构，其中It作形式主语，后面的不定式（短语）为真正的主语。本句的陈述语序为TointroduceMr.Li,ournewmanagertoyouallismypleasure。故选D

3.B这位备受赞誉的法国钢琴家结果却让人大失所望。

［考点］词义辨析

【精析】Bturnin：上交；turnout：结果是，证明是，turnouttobe意为结果成为；turnup：偶然出现，露面，调高；turnover:翻身，翻转。根据句意可知，选B

4.C

5.A当我到了电影院时，电影已经开始了。

［考点］动词时态

【精析】A分析句子结构可知，本句为when引导的条件状语从句，主句的动作发生在从句之前，即过去的过去，所以应用过去完成时。故选A

6.B等你到伦敦时，我们将已在欧洲两周了。

［考点］动词时态

【精析】Bbythetime引导时间状语从句时常与完成时态连用。当从句使用一般现在时表示将来时，主句通常用将来完成时，表示持续到将来某一时间之前的动作。根据从句中的arrive可知，从句使用了一般现在时表示将来，所以选B

7.B多穿点，否则你会感冒的。

［考点］词义辨析

【精析】Bonthecontrary：正相反；orelse：否则，要不然；orrather：倒不如说；innoway：决不。根据句意可知，前后句表示转折关系，所以应用orelse。故选B

8.B你所能做的就是安慰她，耐心地听她的故事。

［考点］定语从句

【精析】B分析句子结构可知，空处和is之间是定语从句，修饰先行词All，从句中缺少do的宾语，所以应用关系代词that引导，Allthat相当于What。如果定语从句的先行词为all,none,nothing,something,everything,anything,much,little等不定代词或被这些不定代词修饰时，关系代词一般用that，且that可以省略。故选B

9.A我喜欢思考新设计。这会使我的头脑保持清醒活跃，还会让我的退休生活充满乐趣。

［考点］词义辨析

【精析】Ajoy：欢乐，快乐，乐趣；anxiety：焦虑，忧虑，渴望；sorrow：悲伤，痛苦，懊恼；anger：愤怒，生气。根据句意可知，选A

10.B直到他让我离开，我才离开。

［考点］动词时态和词语搭配

【精析】B根据句意和题干中的until一词可知，此处考查的是not…until结构，意为直到……才。因为until后面的句子用的是一般过去时，所以前面也应用一般过去时。故选B

11.CC根据句中的时间状语bynextyear（到明年）可知，此处表示在将来这一时间点前已经完成了某事，所以从句应用将来完成时，即willhave+过去分词的形式。根据句意可知，work和complete之间为逻辑上的动宾关系，所以从句应用将来完成时的被动形式，即willhavebeen+过去分词的形式。故选C

12.D杰克总是乐于帮助有困难的人，并且他从不拒绝他们的请求。

［考点］词义辨析

【精析】Dturnup：出现，露面，调高；turnover：翻转，仔细考虑；turnin：上交，交还；turndown：调低，拒绝（建议、要求、邀请等）。根据句意可知，选D

13.D他是唯一一个已经出国三年的学生。

［考点］主谓一致和动词时态

【精析】D当定语从句的先行词为theonlyone+复数名词时，从句的谓语动词应用单数，所以排除选项B和C。时间状语for+一段时间，since，sofar等常与现在完成时连用，表示动作从过去某个时间开始，延续到现在，并仍然可能延续下去，所以本题应用现在完成时。故选D

14.B【翻译】我现在所能做的只有等待。［考点］非谓语动词Bdonothingbut为固定句型,意为“只能做”。若but前面的动词部分有do的某种形式,则but后面的to要省略,直接跟动词原形；若前面没有do的某种形式，则but后应加上to。由句中的do可知，but之后要用省略to的不定式。故选B。

15.D既然我们已经准备好了所有的材料，我们应该马上开始新的任务。

［考点］词义辨析

【精析】D句中空格处需要填入表示既然的引导词，引导让步状语从句，nowthat意为既然。故选D。since也表示既然，可直接引导让步状语从句，无需加that

16.D该地区仍然受到房地产开发商的威胁。

［考点］词语搭配

【精析】Dunderthreat为固定搭配，意为受到威胁。其他三个选项均不能与threat搭配使用。故选D

17.C受邀的有五十人，但是其中一些人由于种种原因缺席了。

［考点］主谓一致

【精析】Cthenumberof…意为……的数量，其后的谓语动词应用单数形式；anumberof…表示许多，若干，其后的谓语动词应用复数形式。故选C

18.D既然你已经熟悉了作者的思路，请尽可能快地读完所有章节。本题考查状语从句。根据句意可知，主句和从句为因果关系。nowthat意为既然，可以引导原因状语从句；aslongas意为只要，引导条件状语从句；eversince意为从那时起，可以引导时间状语从句；sothat意为为了，可以引导目的状语从句。综合上述可知，答案为D

19.D上周我们办了一个晚会，非常有趣，我们再办一个吧。

［考点］词义辨析

【精析】Dmore：更多的；theother：两者中的另一个；other：其他的，表泛指，后接复数名词；another：又一，再一，另外的，表泛指，后接单数名词。anotherone意为另一个，又一个。故选D

［考点］词义辨析

【精析】Aregular:定期的，常规的；normal:正常的，正规的；average:平均的，一般的；ordinary:普通的，平常的。根据句意可知，选A

21.IK根据空后的名词短语15years可知，空处应填介词。符合要求的选项有C、K。句意：15年来，来自伦敦大学学院的专家们一直在调查超过6,700名英国人的生活方式。故选K。

22.HH分析句子结构可知，空处应填引导词，引导一个定语从句，修饰指人的先行词friends。符合要求的选项只有H。句意：学生在上大学时可以学习并交到将持续一生的朋友。故选H。

23.JA.studied（v.学习，研究）B.continuing（v.继续，持续）C.by（prep.通过）D.who（pron.引导定语从句）E.whose（pron.引导定语从句）F.improve（v.改进，改善）G.truth（n.事实，真相）H.ignored（v.忽视，不予理睬）I.recently（adv.最近，不久前）J.those（pron.那些）K.for（prep.表示一段时间）L.less（adv.更少，较少）J分析句子结构可知，空后的who引导一个定语从句，空处为其先行词，所以空处应填指人的名词或代词。符合要求的选项只有J。those在此处指代上文中的people，此处表达的是“不去（音乐会、演出和博物馆）的那些人”。故选J。

24.D

25.B

26.B

27.B

28.D

29.A

30.A

31.E

32.A由前一句它相当小可知，空处应该是对这个小城镇的描述。所以选项中Thepopulationisonlyabout50,000.最符合语境。故选A

33.C

34.CC为……感到自豪应译为beproudof；被……录取应译为beadmittedinto；对……（很）满意应译为be（quite）satisfied/pleasedwith。A项错将对……（很）满意译成了ispleasedto（乐于）；B项错将为……感到自豪译成了ispleasedwith（对……满意）；C项表达贴切，符合题意；D项的两个句子之间缺少连接词。故选C

35.Drinkingaglassofwaterinthemorningisgoodforyourhealth

36.在这个男女平等的时代，人们强调异性之间要有共同点，好像个性差异就意味着会有矛盾似的。【精析】本句是一个主从复合句。asif意为好像，引导方式状语从句。Inthisageof意为在这个……的时代里；emphasized为动词，意为强调；mean在这里作动词，意为意味着，后面常跟名词、代词或动名词

37.谁第一个面试还没有确定

38.阅读是心智的乐事，颇有点儿像运动：心情热切、知识丰富、思维敏捷才能造就一个好的读者

39.CC本句主要考查几个关键词的翻译。海平面可译成thesealevel；全球气候变暖可译成globalwarming；由于可译为becauseof/asaresultof/intheconsequenceof；一点点地可译为littlebylittle。且根据题干可知，这里应用现在进行时。综上分析可知，选C

41.如果你决定学一门新的语言，你必须全身心地投入

42.一些出乎意料的事情使我不能信守承诺

43.一些批评者们说在孩子四岁的时候送去学校起不了什么作用

46.B［考点］事实细节题

47.B［考点］事实细节题
