【答案】第1题:D

第2题:A

第3题:B

第4题:C

【解析】1.主旨大意题。由第一段“Nowanothertypeofmicroscope,onethatutilizesX-raysratherthanlightorelectrons,offersadifferentwayofexaminingtinydetails;itshouldextendhumanperceptionstillfartherintothenaturalworld.现在，另一种显微镜，利用x射线而不是光或电子，提供了一种观察微小细节的不同方法;它应该把人类的感知能力进一步扩展到自然界。”及第二段“ThedreamofbuildinganX-raymicroscopedatesto1895;制造x射线显微镜的梦想可以追溯到1895年”可知本文讲的是一种新的显微镜，故D项正确。

2.判断推理题。定位第一段中“Eachadvanceinmicroscopictechniquehasprovidedscientistswithnewperspectiveonthefunctionoflivingorganismsandthenatureofmatteritself.显微技术的每一个进步都给科学家提供了新视角对生物体的功能和物质本身的性质。”及“Theinventionofthevisible-lightmicroscopelateinthesixteenthcenturyintroducedapreviouslyunknownrealmofsingle-celledplantsandanimals.Inthetwentiethcentury,electronmicroscopeshaveprovideddirectviewsofvirusesandminusculesurfacestructures.16世纪晚期可视光学显微镜的发明引入了单细胞植物和动物的未知领域。在二十世纪，电子显微镜提供了对病毒和微小表面结构的直接观察。”可知提及可见光显微镜的目的是“从历史的角度来看待x射线显微镜”故A项正确。

3.细节事实题。定位第二段中“Inrecentyears,however,interestinX-raymicroscopeshasrevived,largelybecauseofadvancessuchasthedevelopmentofnewsourcesofX-rayillumination.Asaresult,thebrightnessavailabletodayismillionsoftimesthatofX-raytubes,which,formostofthecentury,weretheonlyavailablesourcesofsoftX-rays.然而，近年来，人们对x射线显微镜的兴趣又复活了，这在很大程度上是由于x射线照明新光源等技术的发展。结果，今天可用的亮度是x射线管的数百万倍，在本世纪的大部分时间里，x射线管是唯一可用的软x射线源。可知B项“直到最近，光源才足够明亮。”正确，ACD三项都没有提及。答案B。

4.判断推理题。定位最后一段中“Rather,theirspecialpropertieswillmakepossibleinvestigationsthatwillcomplementthoseperformedwithlight-andelectron-basedinstruments.相反，它们的特殊性质将使研究成为可能，这将补充那些用光和电子仪器进行的研究。可知C项“X射线将提供其他种类的显微镜无法提供的信息。”正确。

2.单选题

TheMarinesattackedthesouthbeachatdaybreak;（

）asadiversionarymaneuver,acompanylandedonthenorthsideoftheisland.

问题1选项

A.previously

B.later

C.simultaneously

D.subsequently

【答案】C

【解析】考查副词辨析。A选项previously“以前；预先”；B选项later“后来；稍后”；C选项simultaneously“同时地”；D选项subsequently“随后；后来”。句意：海军陆战队在黎明时袭击了南海滩；······作为转移注意力的策略，一个连在岛的北侧登陆。上一句说的“开始攻击南边”与空格处的“在北边登陆”应同时进行，否则失去了转移注意力的意义。因此C选项符合题意。

3.单选题

Inarguingagainstassertionsthatenvironmentalcatastropheisimminent,herbookdoesnotridiculeallpredictionsofdoombutratherclaimsthattherisksofharmhaveinmanycasesbeen（

）.

问题1选项

A.exaggerated

B.ignored

C.scrutinized

D.increased

【答案】A

【解析】考查动词词义辨析。exaggerate“夸大；夸张”；ignore“驳回诉讼；忽视”；scrutinize“详细检查；细看”；increase“增加，增大”。句意：在驳斥环境灾难即将来临的断言时，她的书没有嘲笑所有关于灾难的预测，相反却声称损害的风险在很多情况下被夸大了。由butratherclaims可知此处表转折，意思应与前句相反。只有A项符合题意。

4.单选题

Itisregrettablethatstudentsdonot（

）theirstudentloansandtherebymakeitmoreproblematicforfuturegenerationsofstudentstoobtainthem.

问题1选项

A.reimburse

B.refurbish

C.relinquish

D.recount

【答案】A

【解析】考查动词词义辨析。reimburse偿还，归还；refurbish再磨光，刷新；relinquish放弃，弃绝；recount详述，重新计算。句意：令人遗憾的是，学生没有偿还他们的助学贷款，以致于后来的学生在助学贷款的申请上面临更大的问题。根据therebymakeitmoreproblematicforfuturegenerationsofstudentstoobtainthem.可知A项最符合题意。

【答案】第1题:C

第2题:C

第3题:B

第4题:D

【解析】1.细节事实题。定位到第一段中“thisstrategywasusuallyimplementedatanothercommunity’sexpense这种策略通常是实现另一个社区的代价,”以及“throughthetransferofjobsandrelatedrevenuesthatresultedfromthispractice,onetown’striumphcouldbecomeanothertown’stragedy通过这种做法带来的就业和相关收入的转移，一个城镇的胜利可能成为另一个城镇的悲剧”，可知，在八十年代以前，经济的发展都是本地化的，只能为自己所在的社区带来经济利益。C项“它们可以为它们所处的地区提供真正的经济利益。”正确。

2.细节事实题。定位到第二段“high-techmanufacturingfirmsemployonlyaspeciallytrainedfractionofthemanufacturingworkforce高科技制造企业只雇佣了一小部分受过专门训练的制造劳动力”，以及第三段“indigenousindustryandtalentarekeptathome,creatinganenvironmentthatbothprovidesjobsandfostersfurtherentrepreneurship本土产业和人才被留在国内，创造了一个既提供就业又促进进一步创业的环境”。可知作者是对本土的企业持有比较乐观的态度。

3.细节事实题。定位到第二段“thisapproachwaspreferabletovictimizingothergeographicalareasbytakingtheirjobs这种办法比夺走其他地理地区的工作而使其受害要好”可知与B项“它不会牺牲一个当地劳动力的利益而使另一个劳动力受益。”相符。

4.主旨大意题。文章主要目的在于通过讲解三种不同的经济发展策略，告诉读者哪种发展策略优势比较明显，同时三种发展策略对经济有哪些好的促进作用。故D项“审查和评估用于刺激经济发展的战略和方案。”符合题意。

D.chlorinelevelsmustberoutinelyassessedinpoolwater

【答案】第1题:B

第2题:D

第3题:B

第4题:A

第5题:B

【解析】1.细节事实题。定位到第二段“Chlorinemustberegularlyreplenished.氯必须定期补充”及“ThepHratiomustberegularlymonitoredtoensureaconsistentoptimumrate-oneusuallykeptwithinthespectrumof7to8asmeasuredbyareliablepHmeasuringkit.必须定期监测pH值比，以确保一致的最佳速率-通常保持在一个可靠的pH值测量试剂盒测量的7至8的光谱范围内。”可知B项“必要时监测并加氯”符合题意。

2.作者意图题。由第一段“Thesechemicals,specificallyhypochlorousacidandhypochloriteion,eliminatebacteriabyannihilatingandthenoxidizingtheabhorrentcells.Whenthischemicalreactionoccurs,thebacteriaarerenderedessentiallyharmless.这些化学物质，特别是次氯酸和次氯酸盐离子，通过消灭和氧化可恶的细胞来消灭细菌。当这种化学反应发生时，细菌基本上是无害的。”可知作者主要是想介绍氯气是如何确保泳池干净和安全的。

3.推理判断题。定位到最后一段“Otherpeoplemayfindthatinhalingchlorineatthehighlevelspresentaroundsomepoolsmaybedifficulttotolerate.Stillothersmayexperienceskinirritationafterswimminginapoolcontainingchlorine.Althoughthereareotherchemicalsandcompoundsavailabletocleanswimmingpools,theymaybeprohibitivelyexpensiveorincapableofkillingalltypesofbacteriapresentinthewater.其他人可能会发现，吸入一些泳池周围高浓度的氯可能很难忍受。还有一些人在含有氯的游泳池游泳后可能会感到皮肤刺激。虽然有其他化学物质和化合物可以用来清洁游泳池，但它们可能昂贵得令人望而却步，或者无法杀死水中存在的所有类型的细菌。”可知有些人吸入一些泳池周围高浓度的氯可能很难忍受。故B项“偶尔泳池里的氯含量高可能是无害的。”表述错误。

4.推理判断题。作者通过举例直观地解释PH值的知识，让读者有一些了解

5.细节事实题。根据对本文第二段的理解，一旦氯气在太阳光下，那么它的有效性就会降低，而第一段指出氯气中发生反应的化学元素主要是次氯酸和次氯酸离子，但这无法推理出就仅仅只有这两种物质，B项“氯由两种化学物质组成：次氯酸和低氯离子”答案过于绝对。

7.单选题

）aslanguageandliterature,skillfullyused,couldmakeit.

问题1选项

A.enthralling

B.impenetrable

C.lucid

D.deliberate

【答案】B

【解析】考查形容词词义辨析。enthralling迷人的；impenetrable不能通过的；费解的；lucid明晰的；透明的；易懂的；deliberate故意的；深思熟虑的；从容的。句意：第一次世界大战开始于行话和精致言语的环境中，然后像语言和文学在巧妙地使用的情况下可以做到的那样继续于费解的委婉语的阴云中。从continuedinacloudofeuphemism（委婉语的阴云中）可知B项“费解的”符合题意。

【解析】1.细节事实题。定位到第三段中Inlakesandrivers,theacidaltersthebloodchemistryinfish.Themetals,meanwhile,irreversiblydamagethegillsystemsofcertainspecies,suchasbassandwalleye.Astheconcentrationofpoisonrises,egghatchingisreducedandthenumberofdeformedembryosincreases.在湖泊和河流中，这种酸会改变鱼类的血液化学成分。与此同时，这些金属对某些物种的鳃系统造成了不可逆转的损害，如鲈鱼和海参。随着毒素浓度的增加，卵孵化减少，畸形胚胎的数量增加。”可知A项正确。

2.判断推理题。定位到第一段中“Asaresult,weknowmoreaboutacidrainanditseffects,thaneverbefore,butitseemsaregulatorysolutionhasneverbeenfurtheraway.因此，我们比以往任何时候知道更多关于酸雨及其影响，这似乎是一个前所未有的监管解决方案。”可知C项正确。

3.判断推理题。定位最后一段中“ThesecondreasonisthevaryingchemicalmakeupofNorthAmericansoils,Westernsoilsarerelativelyrichinneutralizingcompoundslikemagnesiumandcalciumcarbonates,butthecoarse,shalloweasternsoilshavemuchlessofthisbufferingcapacity.第二个原因是北美土壤的化学组成不同，西方土壤相对丰富的镁和钙碳酸盐中和化合物，但东部粗糙、浅层土壤的这种缓冲能力要小得多。”可知A项西部土壤中的元素中和了这种酸正确。

4.细节事实题。定位到第三段中“Corrosionofmetalstructuresinwindwardareasofthecountryhasbeenwell-documented,butitisarelativelyminorentryonthelist.（酸雨）对金属结构的腐蚀在该国（美国）迎风的地区是显而易见的，不过该腐蚀所带来的损害在酸雨所带来的损害名单上却是相对较小的。”可知D项正确。

）,aslight,isgivenoffandabsorbedindefiniteunitscalledquantaorphotons.

问题1选项

A.energythat

B.thatitisenergy

C.itisenergy

D.thatenergy

【答案】D

【解析】考查宾语从句。states是谓语，后面接一个句子做宾语。宾语从句需要一个引导词that,另外宾语从句还缺少主语，故D项正确。句意：量子理论认为，能量，比如光，是以量子或光子的基本单位来释放和吸收的。

【答案】C

【解析】考查动词词义辨析。reassessed对······再评价；disdained鄙视，蔑视；flunked放弃，失败；redeemed赎回，恢复。句意：当老师发现他班上有一半的学生放弃了考试的时候，他的自尊心受到严重打击。由前后语义可知空格处所填单词为贬义词，与考试搭配的最合适的选项是C项。

【答案】第1题:D

第2题:D

第3题:A

第4题:A

【解析】1.判断推理题。由第一段“AsbefitsanationmadeupofimmigrantsfromallovertheChristianworld,AmericanshavenodistinctiveChristmassymbols.以及ThoughwehavenoChristmassymbolsofourown,theAmericanChristmasstillhasadistinctiveaurabyvirtueoftwocharacteristicelements.作为一个由来自基督教世界各地的移民组成的国家，美国人没有独特的圣诞符号。以及虽然我们自己没有圣诞节的象征，美国圣诞节仍然有独特的气场的两个特征元素。”由此可知作者对于美国庆祝圣诞节的方式的态度是客观的，没有掺杂主观情绪在其中。故D项正确。A项“不同意”；B项“幽默的混乱”；C项“赞美的赞誉”；D项“客观分析”。

2.判断推理题。A项“在马萨诸塞湾的殖民地，某清教徒犯罪，被处罚金，不能庆祝圣诞节”不符合题意。B项“在欧洲和美国，与耶稣诞生节相关的圣诞节习俗最初并不是基督教的。”不符合原文。C项“红鼻子驯鹿鲁道夫(Rudolph)已经成为圣诞节的传统元素，但它是几年前才由商业利益创造出来的。”圣诞老人的出现并不是由于商业原因。D项“在世界广泛的区域，宗教纪念活动往往与惊人的自然现象紧密相连。”由Second,theChristmasseasonoffestivitieshasinsensiblyco
