seahare【答案】（1）C（2）B（3）C【解析】【分析】本文是一篇说明文，介绍了一些野生动物是如何进行自身防御的。（1）考查细节理解。根据

SeaHare(海兔)部分中的“Theseaharegivesoutaslimy,purpleink,thesubstancewhichmakesfoodlesspalatabletopredators.”可知，海兔身上散发出黏糊糊的紫色墨水，这种物质使得捕食者对食物不那么感兴趣，从而保护自己免受捕食者的伤害。故选C。（2）考查细节理解。根据

Opossum(负鼠)部分中的“Inordertobecome‘dead’,theydon'thavetofaxanyoneadeathcertificate.Theyjustlietherewiththeirtongueshangingoutwiththesmellofdeadflesh,sometimesforhours,effectivelyconvincingpotentialpredatorstheycanfindamuchfreshermealelsewhere.”可知，负鼠假装死亡，让捕食者在其他地方找到更新鲜的食物，以避免成为捕食者的目标。故选B。（3）考查推理判断。根据Millipedes(千足虫)部分中的“Theirmajordefenseistocurlupintoaball.They,though,alsoreleaseaharmeyes,andleaveahorriblesmellontheirattackers.”可知，千足虫主要防守是蜷成一团。然而，它们也会释放出有害的

眼睛，并在攻击者身上留下可怕的气味。从而可以推断出，千足虫是拥有多种防御机制的物种。故选C。【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇科普类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，从而选出正确答案。2．犇犇阅读下面文章，然后从题中所给的A、B、C、D四个选项中，选出每个问题的最佳选项。

AninternationalteamofresearchersfromtheUniversityofOxfordhavefoundthatthewaypeopleusetheInternetiscloselytiedtotheseasonalmovementsinthenaturalworld.Theironlinespeciessearchesfollowthepatternsofseasonalanimalmigrations(迁徙).

B.

C.

D.

Uncaring【答案】（1）B（2）C（3）D（4）A【解析】【分析】本文是一篇说明文，在手术室里，医生和护士都戴着手术帽和口罩，只露出眼睛和眉毛，这让周围的人认不出他们，导致在交流过程中产生误会。于是，一位澳大利亚的医生Rob提出在手术帽上写上名字和职位，这一想法逐渐得到了全世界很多国家的认可。（1）考查推理判断。根据第一段中的“Inordertosolvetheproblem,adoctorinSydney,Australia,calledRobHackettlaunchedacampaignname‘"Theatre(手术室)CapChallenge’-encouragehospitalstaffstowritetheir'namesandrolesontheircaps.”Rob提出在手术帽上写上名字和职位，由此可知他是支持这一想法的。故选B。（2）考查推理判断。根据第二段中的例子和第三段中的"The'TheatreCapChallenge'isinresponsetoconcernsabouthoweasilyavoidablemistakesandpoorcommunicationarecontributingtorisingharmfuleventsforourpatients."可知，TheatreCapchallenge活动是为了应对不断增加的病患相关不良事件，而这些事件常是由一些很容易避免的错误和沟通障碍引起的。所以这项活动目的是尽量避免错误和交流中的误解。故选C。（3）考查词义猜测。根据第三段中的“

Weneedtodevelopsystemswhichreducemistakesandmisunderstandingwithoutcausingharm.”可知,他们想建立一种在不造成伤害的情况下尽可能减少错误和误解的系统，而要达到这个目的，首先要让每个人知道医生是人类，是有人情味的。只有病人也感觉到医生的善良，才能减少病患之间的误解。故选D。（4）考查观点态度。全文最后三句是站在患者角度阐述这个活动的意义。从其中的"unworried（不担心的，不着急的）"和"relaxed（松懈的，放松的）"两个词可以知道，这个活动能让病人心情放松，病人对这一做法是很支持的。故选A。【点评】本题考点涉及推理判断，词义猜测和观点态度三个题型的考查，是一篇科教类阅读，要求考生根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。4．犇犇阅读理解

在大型公共场所，很难像机场那样设置昂贵的安检设施。检查行李总是需要人力，我们希望开发一种互补的方法来减少人力，可推知选A。（4）考查词义猜测。根据最后一段中的“Futureworkwillcontinuetofocusonamelioratingtheaccuracyofidentifyingobjectsandimagingshapesandvolumes”今后的工作将继续侧重于提高识别物体和成像形状及体积的准确性，故选B。【点评】本题考点涉及细节理解，词义猜测，推理判断和段落大意四个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。5．犇犇阅读理解

“Researchers…surveyed149respondentsaged21o65abouttheproportionofgreenspaceintheirneighborhood…”研究人员调查了年龄在21~65岁之间的149名参与者小区内的绿植比例……；以及“Thestudyalsoaskedquestionsaboutexperienceswithdepressionandanxiety…”研究中还问了与抑郁及焦虑有关的问题……等可知，第二段主要介绍了新研究的调查内容，故选D。（2）考查词义猜测。根据常识可知，在大自然中散步对人体有各种各样的好处，再结合句中出现的“relievingothermooddisorders(缓解其他情绪紊乱)”不难推断出，combattingdepression应表示“减轻抑郁”。故选A。（3）考查细节理解。根据倒数第二段中的“…addsanewdimension(方面)tothepreviousresearch”为以前的研究增加了新的方面，可知，新的研究在某种程度上丰富了之前的研究成果。故选B。（4）考查推理判断。纵观全文可知，本文介绍了一项科学研究的研究成果，所以该文章最有可能出现在“技术与科学”版块。故选C。【点评】本题考点涉及细节理解，词义猜测，推理判断和段落大意四个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。7．阅读理解
