六、作文题(1题)54.WaterShortage

1.水资源短缺现象成为一个日趋严重的问题

2.造成这一现状的原因

3.可能的解决措施

参考答案

1.B那座城市现在正在修建一个钢铁厂和几家卫星厂。

［考点］主谓一致、动词时态和语态

【精析】B由aswellas,alongwith,togetherwith,with等连接的并列主语在意义上更强调前面的主语，谓语动词通常与前面的主语在人称和数上保持一致，所以本句谓语动词应与works保持一致。works（工厂）是单复数同形的名词，作主语时，其后的谓语动词需根据具体的语境来确定。根据句意可知，iron和steel共同修饰works，表示钢铁厂，且前面有不定冠词An修饰，所以谓语动词应用单数形式。根据句中的now可知，本句应用现在进行时，表示现阶段正在进行的动作。又因为Anironandsteelworks和build之间为逻辑上的动宾关系，所以应用被动语态。故选B

2.C工厂的员工数量已被削减到了最低限度，以降低生产成本。

［考点］主谓一致和动词语态

【精析】Cthenumberof意为……的数量，作句子的主语时,谓语动词用单数形式。由于Thenumberofemployees和cut之间为逻辑上的动宾关系，所以要用被动语态。故选C

3.B那件T恤太紧了，所以他决定把它改大。

［考点］非谓语动词

【精析】B根据句意可知，enlarge和it（Tshirt）之间是逻辑上的动宾关系，所以应用过去分词形式enlarged。另外，havesth.done可视为一种固定表达，意为使某事/物被做。故选B

4.A

5.B抱怨是没有用的，你只能默默忍受这些。

［考点］非谓语动词

【精析】BIt’snogood/use后跟动名词形式作句子真正的主语，It为句子的形式主语，也可将It’snogood/usedoingsth.视为固定搭配，意为做某事是没有用的。故选B

6.CC由句中的时间状语lastweek可知，后一句应用一般过去时，表示过去某个特定时间或某一段时间内发生的动作或存在的状态。故选C

7.B那位老农过去常常花一个小时步行到镇上去卖菜，不是吗?

［考点］反意疑问句

【精析】B当陈述句部分有usedto时，反意疑问句部分用didn't或usedn't。结合选项可知，选B

8.C街道两旁有很多高档的时装店和高级的餐厅。

［考点］词义辨析

【精析】Call：全部，所有，表示三者或三者以上都……；each：每个，各自，其后接单数名词；both：两者都，其后接复数名词；every：每个的，其后接单数名词。表示街道两旁自然用both，故选C

9.D我们确信，通过我们的努力，在不久的将来，我们城市的环境会得到很大的改善。

［考点］动词时态和语态

【精析】D根据时间状语inthenearfuture可知，本句应用一般将来时态，所以排除选项B和C。另外，environment和improve为逻辑上的动宾关系，所以应用被动语态。故选D

10.C经过仔细考虑之后，他拒绝了这项计划。

［考点］非谓语动词

【精析】C分析句子结构可知，前面应用分词形式作状语，he和consider之间是逻辑上的主谓关系，所以要用现在分词形式。又因为consider所表示的动作发生在reject所表示的动作之前，故要用现在分词的完成式。故选C

11.D火车在他的视线中消失后，那个秘书才离开火车站。

［考点］倒装句和动词时态

【精析】Donly+状语从句位于句首时，主句应用部分倒装结构，即将谓语中的助动词、情态动词或be动词提至主语之前。根据从句中的saw一词可知，主句应用一般过去时，所以应将助动词did提至主语he之前。故选D

12.C我们的学生可以自由选择任何他们感兴趣的内容来学习。

［考点］名词性从句

【精析】C空处需要一个连接代词来引导宾语从句，该代词在从句中作主语，并且该词应表示不论什么的意思。四个选项中只有选项C符合题意，whatever相当于anythingthat。故选C

13.B在这家商店你付现金或刷信用卡都无所谓。

［考点］主语从句

【精析】B本题考查whether…or…引导的主语从句的用法。分析句子结构可知，句中的It是形式主语，真正的主语是空处引导的主语从句。由从句中的or可知，应选whether构成whether…or…结构，表示选择。故选B

14.D

15.D——你们班有多少留守儿童？

——一个也没有。

［考点］词义辨析

【精析】Dnothing：没什么，没事，没有东西；nobody：无人，没有任何人，不强调数量，可用来回答who问句；neither：两者都不；none：没有人，一个也没有，既可指人又可指物，强调数量，可用来回答howmany/howmuch问句。根据句意可知，此处强调数量，所以应用none来回答。故选D

16.D特蕾西说话太轻了，我听不见她说话。

［考点］词语搭配

【精析】Dso…that…意为如此……以至于……，引导结果状语从句。其他三项不能与that搭配。故选D

17.D只有在紧急状况下，你才能使用这个门。

［考点］固定用法

【精析】Dinanemergency是固定搭配，意为在紧要关头，遇到紧急情况。故选D

18.B能坐在前排座位看我最喜欢的乐团，是多么棒的一件事啊！

［考点］感叹句

【精析】B常用的感叹句的基本结构为：①What（+a/an）+形容词+名词（+主语+谓语）！②How+形容词/副词+主语+谓语（+其他）！③How+形容词+a（n）+名词+主语+谓语！wonderful是形容词，后面没有名词，其前不用不定冠词，符合第二种结构，所以应选B

19.D我肯定不愿意犯错的时候被指责。

［考点］非谓语动词

【精析】Dappreciate后面常跟动名词作宾语，且此处表示被指责，故选动名词的被动式beingaccused

20.B所以，总之我们必须获取更多的资金。

［考点］固定用法

【精析】B四个选项中，只有insummary这一短语有实义，意为总之，概括起来。故选B

21.GK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.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。

23.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。

41.CCA项将为……做出贡献错译为把……归因于；B项中应将第二个are去掉，使willing…和devoted…作individuals的后置定语，否则句子结构不正确；D项将愿为误译为不情愿。故选C
