Martin认为应当让孩子从幼年时期便开始在近水区域活动并培养水上运动技巧，因为这会让他们终身受益。34.A。理解文章结构。第三段第一句为本段中心句，后面的A review.及Another review.为具体的例子，由此可推知，本段主要通过举例子说明在过去的十年中，关于蓝色空间会对心理健康产生有益影响的研究越来越多。35.C。推断。根据最后一段内容可推知，Mathew White认为如果该发现得到长期跟踪研究的支持，鼓励人们在童年时期接触更多蓝色空间将是提升后代精神健康的切实可行的方法。第二节主题语境：人与自我一一生活本文是说明文。文章对“成年”给出了定义。36.B。设空处承上启下，起过渡作用。设空处上文指出“ADULT”这个词可以拆分为囊括个人发展必备素质的五个部分，下文给出具体阐释，由此可推知，设空处应当指出下文与这五个素质的关联，B项符合语境。B项中的these指代上文中的qualities和下文中的五点内容。37.F。设空处位于段首，起引出话题的作用。根据设空处下文中的our parents would..forthese acts和However,,as an adult可推知，本段主要通过孩提时代与成年时期的对比说明负责任的品质是成熟的重要标志之一，设空处应当指出孩提时代的任性行为，F项符合语境。F项中的As a baby与下文中的as an adult构成对照，设空处下文中的these acts指代F项中的cry unnecessarily or even mess up the place。38.C。设空处与上文为解释关系。设空处上文将“沉溺于自我”与“手中紧握玫瑰”作比，指出两者均有相似的不良后果，由此可推知，设空处应当对这种相似的不良后果做出具体解释，C项符合语境。C项中的hold与上文中的holding构成原词复现，C项中的wound与上文中的harmful effect构成同现关系。39.A。设空处承接上文，进一步作出说明。设空处上文指出倾听他人讲话时，他人的想法与观点会直接传达给我们，设空处下文做出总结：以理解为目的的倾听是当前的需要，由此可推知，设空处应当说明倾听的好处，A项符合语境。A项中的This指代上文中的listen toothers.40.G。设空处位于段末，起总结全段主旨的作用。根据小标题及本段内容可知，本段主要介绍成年意味着要有自己的立场，G项符合语境。G项中的opinions by others与上文中的parents'suggestions.social media相照应，G项中的take our own stand与小标题中的TAKE ASTAND相照应。语言运用第一节主题语境：人与自我一一生活本文是记叙文。一位父亲讲述了自己为儿子精心准备的成人礼。41.B。由该空前的from a simple occasion和该空后的that cover.special moment可推知，成人礼既可以是一个简单的事件，也可以由持续数日的特别事件组成。42.A。由上文中的my19-year-old son Eric和本段中的now22可知，Drew是Eric的哥哥。43.C。由本段中的I organized.eight men和下文中的内容可推知，“我”为Eric安排了与哥哥不同的成人礼。44.B。45.D。由最后一段中的Before the basketball fun started可推知，“我”租下了健身中心，这样Eric就可以跟他的好友打篮球了。46.D。由本段中的Eric was thrilled可知，Eric看到“我”准备的东西非常激动，由此可推知，这些影片是Eric最喜欢的。

having richer and more diverse bacterial populations in this part of the gut可知，细菌种群能够阻止蠕虫的活动，也就是说对羊群来说是有益的。3l.B。理解主旨要义。根据最后一段中的a third approach..is to employ probiotics to shapethe gut microorganisms of flocks directly可知，Paz博士通过研究发现使用益生菌或可直接塑造羊群的肠道微生物群，故B项内容（改变羊群）作为标题最贴切。D篇主题语境：人与社会一一人际沟通本文是说明文。文章通过三项实验表明：我们在考虑别人对我们的看法时，往往会低估他人对自己的喜欢程度。32.C。理解具体信息。根据第一段中的the liking gap,.whereby two people meeting for the firsttime routinely underestimate how much their counterparts like them可知，这种名为“喜欢分歧”的现象，是指首次见面的两个人往往会低估对方喜欢自己的程度。也就是说，误判对方对自己的看法。33.D。理解具体信息。根据第二段中的On average,people liked their partners more than theybelieved their partners liked them,and thought themselves to be the least-liked in the group知，人们对自己感到不太自信。34.B。理解词汇。根据第三段中的people tended to underestimate the degree to which theywere liked reduced their willingness to ask others for help,give honest feedback,and worktogether in the future可知，人们不太看好自己。由此可推知，dim意为“消极的”。35.A。理解具体信息。根据最后一段中的Managers should think carefully not just about howteammates regard one another but about how team members think they themselves areregarded可知，管理者不仅要仔细考虑团队成员之间的看法，更要考虑团队成员认为他们自己是如何被看待的。第二节主题语境：人与自我一一生活本文是说明文。作者就如何保持家中清洁给出了几点建议。36.D。根据设空处后的When everything is where it should be,it saves a lot of time可知，作者建议物有所归，应该做到井井有条，D项中的everything in its place与设空处后的everythingis where it should be相互呼应。37.G。根据设空处前的You just need an all-purpose cleaner,,a disinfectant and a windowcleaner和设空处后介绍的后两种物品可知，G项介绍第一种一一全能清洁剂，符合语境。G项中的all-purpose cleaner与设空处前的al-purpose cleaner为原词复现。38.C。根据设空处后的For example,in your bedroom,clean the light fixtures before removingthe sheets on a bed.I learned that lesson when I first started by taking off all the bed sheets.Then all the dust fell onto my mattress directly可知，作者认为清洁工作应该由上而下完成。39.B。根据设空处前的make sure to dry clean before you wet clean和所举例子可知，如果先用清洁剂和湿抹布擦洗百叶窗上的灰尘，你就会发现抹布上粘满了黏糊糊的污垢，于是不得不更频繁地更换抹布。由此可见，这样做效率不高，故B项内容符合此处语境。4o.A。根据本段第一句Try to set a schedule for daily,weekly and monthly cleaning tasks和其后的相关说明可知，作者在此建议将清洁工作列为常规事项，应该具体到日、周、月，故A项内容作为本段小标题最贴切。语言知识运用第一节主题语境：人与自我一一做人与做事
