D.

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。4．犇犇阅读理解
