D.view

【答案】B

【解析】考查语法知识。A选项surround“围绕，包围”；B选项circle“盘旋，环绕……移动”；C选项observe“观察，遵守”；D选项view“观察，考虑”。句意：为了熟悉飞机的操纵，这个人不得不环绕着机场飞行了好几次。选项B符合语境。

2.单选题

问题1选项

A.flight

B.travel

C.crossing

D.journey

【答案】D

【解析】考查名词词义辨析。选项A：flight意为“飞行，航班”；选项B：travel“旅行，旅游”（泛指）；选项C：crossing意为“横越，横渡”；选项D：journey“（侧重指时间较长、距离较远的单程旅行）行程，路程”。由题意可知，本题的正确选项为D选项。句意：从机场回来的路真的很累人，因为它离城市很远。

3.单选题

问题1选项

【答案】C

【解析】考查形容词比较级。句意：心脏不比胃聪明，因为它们都由大脑控制。根据题干intelligentthan可知考查形容词的比较级，确定有more，根据语境心脏和胃都受大脑控制确定C选项nomore符合题意。因此C选项正确。

4.单选题

5.单选题

Justlikelastyear’ssmartphone,theMate10modelswill________performanceovertimebylearningwhichappsyouuseregularly.

问题1选项

A.optimize

B.substitute

C.legitimate

D.mobilize

【答案】A

【解析】【选项释义】

A.optimize优化，充分利用B.substitute代替，取代

C.legitimate使合法，使正当D.mobilize组织，动员

【考查点】动词辨析。

【解题思路】空格处和下文的“performance（性能）”构成动宾逻辑，表示Mate10这款手机会怎么样自己的性能，它的方式是“通过了解你经常使用的（useregularly）应用程序”，由此可知，这样会使手机的性能更好。optimize指使某物尽可能好或以最好的方式使用某物，因此A选项optimize“优化，充分利用”最符合题意。

【干扰项排除】

B选项substitute“代替，取代”指用某事物取代另一事物，不符合题干的语义逻辑；

C选项legitimate“使合法，使正当”指使某物或某人合法化，不符合题干的语义逻辑；

D选项mobilize“组织，动员”指组织一群人为达到某一特定目标而共同努力，不能和“performance（性能）”进行搭配。

【句意】就像去年的智能手机一样，Mate10将通过了解你经常使用的应用程序，随着时间的推移来优化性能。

【答案】第1题:C

第2题:D

第3题:C

第4题:C

第5题:C

【解析】1.本文主要是讲述大象能够改变居住环境,从而影响其他物种的生存,选项C正确。

2.根据关键词"tigers""whales"定位到第一段第三句"Unliketheendangeredtiger,unlikeeventhegreatwhales,theAfricanelephantisingreatmeasurethearchitectofitsenvironment."不像濒临灭绝的老虎,甚至不像大型鲸鱼,非洲象在很大程度上是环境的建筑师。也就是说大象能够改变环境,选项D符合原文。

3.根据第二段的第一句"Itistheelephant'smetabolismandappetitethatmakeitadisturberoftheenvironment"大象能够改变环境是因为它们的新陈代谢和食欲。选项C正确。

4.根据第三段第一句"whenelephantsareallowedtoroamdiesavannasnaturallyandnormally,theyspreadoutat"intermediatedensities.""可知,大象不是群居动物,所以选项A错误;根据倒数第二段的内容可知,选项B表达的刚好是相反的情况,所以错误;根据最后一段的第一句"...therainforestbecomeshospitabletolargeplant-eatingmammals..."可知选项D错误。根据第三段的内容可知,大象改变环境会产生种类繁多的食草动物,食草动物又吸引了食肉动物。也就是说大象对某些食肉动物的捕猎方式有间接影响。选项C符合原文内容。

5.结合全文内容可知,大象改变环境给其他物种创造了适宜其生存的环境,这是偶然性的而不是大象刻意为之的,所以选项C正确。

7.单选题

Theotherday,IsawGrandpasittinginthegarden______themoonwhilemurmuringtohimself.

问题1选项

A.staringat

B.lookingat

C.glancingat

D.gazingat

【答案】D

【解析】考查短语辨析。A选项stareat“凝视；盯着；目不转睛地看”；B选项lookat“看；考虑；着眼于”；C选项glanceat“扫视；浏览；匆匆一瞥”；D选项gazeat“盯住；凝视；注视；注目”。stareat表达的是好奇或无礼傲慢；glanceat表达的是匆忙；gazeat表达的是感慨、喜欢或惊奇。stareat和glanceat的动作维持的时间比较长；glanceat的动作维持时间非常的短。句意：有一天，我看见爷爷坐在花园里，凝视着月亮，喃喃自语。此处的凝视带有浓厚的感情色彩，因此D选项正确。

8.写作题

问题1选项

A.sober

B.faulty

C.prompt

D.fussy

【答案】B

【解析】考查形容词词义辨析。A选项sober“清醒的”；B选项faulty“错误的”；C选项prompt“敏捷的”；D选项fussy“爱挑剔的”。句意：调查人员认为火灾是由错误的电线引起的。他们说，大楼的布线不是由专业电工完成的。本句表示错误的电线布线。因此B选项正确。

10.单选题

InBritontherobinisasmallbird,butits（）inAmericaismuchlarge.

问题1选项

A.species

B.counterpart

C.analogy

D.category

【答案】A

【解析】句意：在英国知更鸟是一种小鸟,但在美国它的物种要大得多。species物种,种类；counterpart相似物；analogy类比,类似；category种类,分类。选项A形容生物种类,所以选项A正确。

11.单选题

）medicalproblemsthanemergencycare.

问题1选项

A.perplexing

B.complex

C.prudent

D.pressing

【答案】D

【解析】perplexing使人困惑的，令人费解的；complex复杂的，合成的；prudent谨慎的，精明的；pressing紧迫的，迫切的。句意：医院将紧急护理定义为医疗问题比急救护理稍微不那么紧迫的医疗护理。选项D符合语境。

12.单选题

Nomatterhowangryhewas,hewouldnever（

）toviolence.

问题1选项

A.resolve

B.resign

C.exert

D.resort

【答案】D

【解析】考查动词辨析。A选项“决心做，溶解”；B选项“离职，委托”；C选项“运用，施加影响”；D选项“凭借，诉诸”。句意：无论他有多生气，他都绝不会（）武力。这里根据句子，词义应该选诉诸，所以答案选D。

【答案】第1题:D

第2题:C

第3题:A

第4题:B

【解析】1.细节事实题。由文章开头‘Thousandsofyearsagomanusedhandyrocksforhissurgicaloperations.Laterheusedsharpboneorhorn,metalknivesandmorerecently,rubberandplastic.’20世纪60年代之前，外科手术使用过的工具有：石头，锋利的骨头和角，金属刀，橡胶和塑料。确定这些工具都是很基本的，D选项正确。

2.推理判断题。由第二段中所举的眼科手术的例子可知，使用激光做手术，可以让患者感觉轻松和舒服，不需要很长时间就能恢复，彻底改变了外科手术的方法，C选项正确。

3.细节事实题。根据第一段中“Thelightinalaserbeam,however,isconcentratedThismeansthatalightwithnomorepowerthanthatproducedbyanordinaryelectriclightbulbbecomesintenselystrongasitisconcentratedtoapinpoint-sizedbeam.然而，激光束中的光是集中的，这意味着不需要比普通电灯泡产生更多的能量就能点燃，当它集中在一个针尖大小的光束上时，就会变得非常强烈。”可知，激光光束强是因为它的光束没有分散，而是集中成针尖大小的光束，所以A选项正确。

4.细节事实题。根据“Noknives,nounwanteddamage—truesurgicalwonder.Operationswhichonceleftpatientsexhaustedandinneedoflongperiodsofrecoverytimenowleavethemfeelingrelaxedandcomfortable.没有刀，没有不必要的伤害——真正的外科奇迹。手术曾经让病人精疲力竭，需要很长时间的恢复，现在让他们感到放松和舒适。”可知，使用激光做外科手术，可以让病人遭受极少的痛苦，B选项正确。

14.翻译题

雨落无声，记忆搁浅。用心触摸着那丝丝微雨的柔美，透过时空的壁垒，苍老的故地，深沉的脚印，朦胧的身影，和那被岁月侵蚀的满怀柔情，在脑海里徘徊得太过杂乱无章，每当想要细细品味时，却不知从何道来。于是只能介乎在半梦半醒之间，任沧桑褪尽昔日芳华，孑然一身，谱写出风花雪月的篇章。人生若只如初见，那冥冥中注定的惊鸿一瞥，定格一瞬间，却又转瞬即逝，带走了无限的想象和无尽的回忆。

【答案】D

【解析】competent胜任的,有能力的；compulsory义务的,必修的；comparable同等的,可比较的；compatible兼容的,能共处的。句意：如果一个品牌的电脑与另一个品牌的电脑兼容,它们就可以一起使用,并且可以使用相同的软件。选项D符合句意。

【答案】第1题:B

第2题:A

第3题:C

第4题:A

【解析】第1题:细节事实题。由第二段“Ifhelacksareadyresponseforthesituation,andcannotreasonoutwhattodo,heobservesamodelwhoseemsabletogettherightresult.Thechildlooksforanauthorityorexpertwhocanshowwhattodo.如果儿童对新情况缺乏一个快速的反应，并且不能推断出该做什么，他就会观察学习那些能给出正确结果的人。孩子寻找权威人士或专家来告诉他们该做什么。”可知孩子模仿学习的首要原因是他们需要找到一种能得到想要的结果的方式，他们并不是模仿所有的东西。由此可知B项正确。

第2题:细节事实题。由第三段的举例及“Thechildmaybeabletoattainhisimmediategoalonlytofindthathismethodbringscriticismfrompeoplewhoobservehim.孩子也许能够达到他的直接目标，但却发现他的方法招致了观察他的人的批评。”以及“Thus,thedesiretosolveanyobjectivesituationisoverlaidwiththedesiretosolveitproperly.因此，解决任何客观情况的愿望都被以恰当方式解决问题的愿望所覆盖。”可知用适当的方法来解决问题很重要。答案A

第3题:细节事实题。由第四段“Ifthepupilwantstobeagoodviolinist,hewillobserveandtrytocopythetechniquesofcapableplayers,whilesomeotherpersonmaymostinfluencehisapproachtobooks.如果一个学生想成为一名优秀的小提琴手，他会观察并尝试模仿有能力的演奏者的技巧，如果他喜欢阅读，那么书本上的对他影响最大的人可能是其想模仿的对象。”故C项正确。

第4题:细节事实题。由第五段第一句“Admirationofonequalityoftenleadsustoadmireapersonasawhole,andhebecomesanidentifyingfigure.欣赏一个人的某种品质常常会令我们仰慕整个人，这个人就变成了我们的榜样。由“admireapersonasawhole”可推断出该词意为“榜样”，故答案A

【解析】13.【试题答案】B

【试题解析】主旨大意题。文章首先引出“生物多样性”的定义，介绍了全球大概的物种数量，接着介绍了研究生物多样性的意义，说明本文的主要目的是介绍生物多样性的概念。因此B选项“解释生物多样性的概念”正确。A选项“解释为什么生物多样性对我们的生存至关重要”，原文只提到生物多样性对我们的生存至关重要，没有具体阐述，所以A错误。C选项“说明为什么当地的生物多样性比全球的生物多样性更重要”只是原文的一部分内容，不能概括全文主旨，所以C错误。D选项“阐明生物多样性的减少所带来的危险”，原文没有讲到生物多样性减少的危害，所以D错误。
