六、作文题(1题)54.Directions:Forthispart,youarerequiredtowriteacompositionofabout100words.Yourwritingshouldbebasedonthetitleandoutlinegivenbelow.

ShouldCustomersBuyCut-priceProducts?

1.现在许多人都喜欢买打折商品；

2.而另一些人认为越是打折的商品越不能买；

3.你的看法

参考答案

1.D

2.D新技术发明以来，总产量上升了20％。

［考点］非谓语动词

【精析】D分析句子结构可知，前半句应是一个独立主格结构，所以应选用非谓语动词的某种形式。选项中C项结构不正确；主语technique是动词workout的对象，故此处应用被动语态，选项A、B不正确。故本题选D。注意：主句中的谓语动词用的是过去式，所以独立主格结构中应用完成时表示原因

3.A他不可能在会议上发言，因为他已经回家了。

［考点］情态动词

【精析】A根据句意可知，前一句是对过去情况的否定推测。couldn’thavedone表示对过去已经发生事情的否定推测,意为不可能……，符合题意；mayhavedone表示对过去发生事情的可能性推测,意为可能已经……;musthavedone表示对过去发生事情的肯定推测,意为肯定已经……;shouldn’thavedone意为本不应该做某事却做了。故选A

4.B她说她七点就会到这里。但是直到八点她才出现。

［考点］词义辨析

【精析】Bturnon:打开，发动;turnup:出现，露面;turnout:结果是，证明是;turndown:拒绝，关小，调低。根据句意可知，选B

5.C汤姆的房间里乱七八糟的，一切都杂乱无序。

［考点］词组辨析

【精析】Coutofcontrol：失控；outofdate：过时；outoforder：不整洁，不合规则，杂乱无序；outofservice：失效，停止运行。根据句意可知，此处指房间里乱七八糟，所以选C

6.B收音机、电视和报刊是传递新闻和信息最为普遍的三种方式。

［考点］限定词词序

【精析】Bcommon的最高级形式为themostcommon。如果有几个词同时修饰一个名词时，排列顺序大致为：冠词、序数词、基数词、表示性质的形容词、表示颜色和材料的形容词，所以本题中three应放在mostcommon前，the应放在three前，最后为中心词。由此可知，选B

7.C无论你提什么建议，他都置之不理。

［考点］状语从句

【精析】Cwhatever=nomatterwhat,引导让步状语从句，其后常接名词，意为无论什么。however=nomatterhow,其后常接形容词或副词，意为不管怎样，无论如何。由空后的名词suggestions可知，应选C

8.D低碳生活方式影响着我们的日常生活。近年来人们越来越关注节约能源。

［考点］固定用法

【精析】Dhaveaneffecton为固定搭配，意为对……有影响；payattentionto意为注意，重视，留心，其中to是介词，其后的动词应用动名词形式。故选D

9.BBso和such都表示如此，其区别在于so是副词，修饰形容词和副词，而such是形容词，修饰名词。它们后面都可接单数可数名词，但词序不同。其一般结构为：such＋a/an＋adj.＋n.和so+adj.+a/an+n.。在本句中girl是可数名词，所以应用such修饰。故选B

10.C现今由于家电，做家务事变得容易多了。

［考点］词义辨析

【精析】C四个选项的意思分别为:facilities：设施；equipment：设备，器材；appliances：器具，装置;electrical常与其搭配表示家用电器；utilities公共设施，效用。根据题意可知本题正确答案为C

11.D我们能否成功取决于我们与其他人合作的情况。

［考点］主语从句

【精析】D分析句子结构可知，空处引导的是主语从句，从句成分完整，缺少是否的含义，再结合句中的ornot可知，应用whether引导从句。A、B两项不能引导名词性从句；what引导名词性从句时，在从句中作主语、宾语、表语等成分。故选D

12.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

13.A句意：我必须告诉你我收到你的信有多高兴！本题考查宾语从句的用法。宾语从句中如果是特殊疑问句，也应用陈述句语序，故该从句中的谓语不需提到主语前，所以排除C选项；再根据搭配bepleasedtodosth.排除选项B和D。所以答案为A

14.BB句意：我觉得告诉你我们的决定是我的职责。非谓语动词题。本句中Ifeel之后是一个宾语从句，it是从句的形式主语，真正的主语应是后面的不定式。故选B

15.D令他们的支持者们失望的是，他们拒绝承认自己犯下的惊人罪行。

［考点］冠词的用法

【精析】Dcrime后面有省略关系代词that或which的定语从句theydid修饰，所以这里表示特指，应用定冠词the。故选D

16.C她喜欢因一些琐碎的事和邻居争吵。

［考点］词语搭配

【精析】Cquarrelwithsb.是固定搭配，意为和某人争吵。quarrelaboutsth.是固定搭配，意为因某事争吵。故选C

17.AA分析句子结构可知，空后为一个表语从句，且引导词在从句中作主语，表示人，因此应用who

18.C这条项链由96个部分组成，不管是从各个部分来看还是从整体来看，都很值钱。

［考点］词义辨析

【精析】Cwholly：完全地，整体地，强调完整性；jointly：共同地，联合地；collectively：共同地，全体地，individuallyandcollectively常搭配使用，意为无论个体或集体；completely：完全地，彻底地，多侧重程度，强调不缺乏细节。根据句意可知，选C

19.AA句意：我们系有很多藏书，其中很多是英语书。定语从句题。非限制性定语从句和主句的关系比较松散，只起补充说明的作用，即使省略也不影响主句的意思，从句和先行词之间常有逗号隔开。当先行词是物时，只能用which来引导。因此，本题中用manyofwhich引导一个非限制性定语从句，故选A

20.C

21.FK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。

45.B［考点］事实细节题

【精析】B根据表格第一栏中的Givethemsmallgiftsfromtimetotimetoexpressyourlove.可知，应该经常送给父母一些小礼物来表达你的爱意。故选B

46.BB事实细节题。作者在文章倒数第二段最后一句指出…theycan’tpoliceeverythingthekidsencounterontheInternetorinfriends’homes.即他们不能对孩子在网上看到的所有东西或是朋友家遇到的每一件事都进行监管。故选项B为正确答案

47.D［考点］词语理解题

根据第一段最后一句Ifnomajorstepsaretakentoaddresstheproblem,thereefsmaybeheadedfortotalextinction.可推断出，address是指解决，处理珊瑚礁大量死亡的问题。breakdown：破坏；stickto：坚持；goover：检查，回顾；dealwith：处理，解决。故选D

48.D［考点］词语理解题

【精析】D根据第三
