Thereareoccasionalquarrelsbetweenparentsandchildren.【答案】（1）C（2）A（3）B（4）C（5）D【解析】【分析】本文是一篇说明文，一项研究发现，“回巢族”子女在大学毕业后回到父母身边生活对家庭是有好处的，他们会与父母建立更亲密、更具支持性的关系，并增进两代人之间的联系。而这一发现与今年早些时候发表的一项研究结果相矛盾，该研究显示，返乡的成年子女会导致父母的生活质量和幸福感显著下降。父母和孩子对于独立的紧张情绪会导致父母和子女之间偶尔的争吵。（1）考查推理判断。根据第二段中的“Thefindingsdisagreewiththeresearchpublishedearlierthisyearshowingthatreturningadultchildrentriggerasignificantworseningintheirparents'qualityoflifeandwellbeing.”这一发现与今年早些时候发表的一项研究结果不一致，早些的研究显示，返乡的成年子女会导致父母的生活质量和幸福感显著恶化。可知，以往的研究显示，返乡的成年子女会导致父母的生活质量和幸福感比之前更差，故选C。（2）考查词义猜测。根据第二段中的“Thefindingsdisagreewiththeresearchpublishedearlierthisyearshowingthatreturningadultchildrentriggerasignificantworseningintheirparents'qualityoflifeandwellbeing.”通过新旧研究对比，以往的研究表明，返乡的成年子女会导致父母的生活质量和幸福感显著下降。即可推理划线部分单词trigger意为“导致，致使”，与cause意义一致。故选A。（3）考查细节理解。根据第三段中的“Theyoungadultstakingpartinthestudywere‘morepositivethanmighthavebeenexpected’aboutmovingbackhome–theshameisreducedassomanyoftheirfriendsareinthesameposition,andtheyacknowledgedthebenefitsoftheirparents'financialandemotionalsupport.”参与这项研究的年轻人对于搬回家“比预期的更积极”——他们的羞愧感减少了，因为他们的许多朋友都处于同样的处境，而且他们承认父母在经济和情感上的支持是有好处的。）可知，大学毕业生对回家的态度是积极的，很高兴能够回家，故选B。（4）考查推理判断。根据第四段中的“Buttheyacknowledgedthatthingsweredifferentforgraduatestoday,wholeaveuniversitywithhugedebtsandfewerjobopportunities.”但他们承认，如今的毕业生情况有所不同，他们毕业时背负着巨额债务，工作机会也更少。由此推断出，孩子们很难找到一份满意的工作，故选C。（5）考查细节理解。根据倒数第二段中的"‘However’,thestudysays,‘day-to-daytensionsabouttheprospectsofachievingdifferentdimensionsofindependence,whichinafewextremecasescameclosetoconflict”可知对于实现不同层面独立前景的日常紧张情绪，是大多数家长和略多于一半毕业生经历的特征。在少数极端情况下，这种紧张情绪接近冲突。可知回巢族孩子现象的副作用是在少数情况下，紧张情绪会导致父母和孩子之间偶尔发生争吵。故选D。【点评】本题考点涉及细节理解，词义猜测和推理判断三个题型的考查，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，从而选出正确答案。2．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

Itshouldbecarriedoutstepbystep.【答案】（1）A（2）B（3）A（4）D【解析】【分析】本文是一篇说明文，介绍了SMAs(共享医疗预约)模式，以及这种模式面临的挑战。（1）考查推理判断。根据第二段中的“Incontrasttoone-to-onevisits,SMAprovidealongerappointmenttime-frameaswellastheopportunityforpatientstohaveimprovedaccesstotheirphysiciansandmeanwhilepickupadditionalinformationandsupportfrompeers.”可知SMAs模式为患者提供了更长的预约时间，也为患者提供了更好地与医生接触的机会，同时还能从同行那里获得额外的信息和支持。这说明SAMs的出现是为患者提供更好的医疗服务。故选A。（2）考查推理判断。根据第三段中的“Dr.Sumego,directorofsharedmedicalappointments,ClevelandClinic,……personalserviceandprivacy;theSMAapproachisafundamentalchallengetothosefixedideas.”可知Dr.Sumego认为，文化转变是最大的

挑战。医生和护士接受的是针对个人服务和隐私的培训;SMAs方法是对这些固定想法的根本挑战。也就是说，改变这些已经固定的想法是一种挑战，所以这些固定的想法会阻碍SMAs模式的推广，故选B。（3）考查词义猜测。根据最后一段中的“ifanorganizationwaslookingtostartsharedmedicalappointments，Iwouldadvisethemtostartthebuy-infromafewchampionphysicians”可知如果一个组织要寻求共享医疗模式的话，Dr.Sumego建议他们从一些优秀的医师开始他们的buy-in，根据语境，故选A。（4）考查推理判断。根据最后一段中的“So,ifanorganizationwaslookingtostartsharedmedicalappointments,Iwouldadvisethemtostartthebuy-infromafewchampionphysicians,developthe…appointmentsandthenext.”可知如果一个组织要开始SMAs，Dr.Sumego建议他们从一些优秀的医师开始，开发一些流程，积累一些经验。制定一些标准，以便随着概念的推广，他们可以利用这种经验开始下一次共享医疗预约然后将下次的经验用到下下次。这说明SMAs的实施需要一步一步来，不会一步到位。故选D。【点评】本题考点涉及词义猜测和推理判断两个题型的考查，是一篇介绍类阅读，要求考生根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。3．犇犇阅读理解
