[解析]
(1)A.推理判断题。上文As the proverb goes,beauty is in the eye of the beholder.(俗话说,情人眼里出西施。)说明美感受观察者的主观感受影响。A项"But"表示与上文转折,讲的是环境也很重要,从而引出下文关于幸福感与环境之间的联系的论文研究:"A paper published two years ago in Nature found a connection between people's sense of well﹣being and the scenicness (美景) of where they lived."(两年前发表于《自然》的一篇论文发现,人们的幸福感与他们所居住的地方的景色之间存在联系。)A项符合文意。故选A项。
(2)D.推理判断题。上文The connection,the paper's authors found,held true whether a neighborhood was urban or rural.(论文发现,无论是在城市还是在农村,这种联系都是存在的。)说明无论地点在哪儿,幸福感和环境有关的联系都是存在的;下文Nor did levels of air pollution have any influence on it.(空气污染水平也不对其产生影响)说明与空气污染水平无关。所以设空处也是讲的是影响人们幸福感的因素,而且由下文"Nor"可知设空处也是否定句。D项"It bore no relation to volunteers' social and economic status."(人们的幸福感和参与调查的志愿者的社会和经济地位无关。)符合文意。故选D项。
(3)G.推理判断题。下文The team behind that Nature paper have nevertheless decided to have a go.(尽管如此,该论文的团队还是决定做一番尝试。)的"nevertheless"说明它与设空处之间是转折关系,也就是说,该团队所尝试的内容是有难度的。再根据后面The program's task was to work out,by analyzing each photograph's features in the context of its Scenic﹣or﹣Not ratings,what it is that makes a landscape scenic.(该项目的任务是,通过分析对应不同美景等级的照片的特征,找出使风景被视为美景的因素。)可知,团队尝试分析景色被视为美景的因素。由此推知,设空处的内容与给美景下定义让人苦恼有关,所以G项"Determining what scenicness is,though,has always been frustrating for scientists."(确定美景的概念让科学家们感到沮丧。)符合文意,故选G项。
(4)B.推理判断题。上文In artificial landscapes,castles,churches and cottages were seen as scenic.(人工景观中,城堡、教堂和村舍被视为美景。)讲的是有些人工景观被评为美景。B项"Hospitals,garages and motels were not so much."讲的是医院、车库和汽车旅馆等另一些人工景观的美景评分并不高。上文和设空处讲的都是人工景观的美景评级结果,由此引出下文的结论:The analysis did,however,confirm one important finding from the team's previous study,which is also a message for town planners.Green spaces alone are not scenic.(然而,该研究的确印证了团队先前的一项研究,该研究也给城市规划师提供了建议。绿地自身不是美景)。故选B项。
(5)E.推理判断题。上文Green spaces alone are not scenic.To be so they need to involve contours (高低起伏的轮廓) and trees.(绿地自身不是美景,要有高低起伏的轮廓和树木。)说明要多种些树、具有高低起伏的轮廓才算是风景。E项对上文进行补充,即少一些草地,多一些树和灌木丛才受大家欢迎,符合文意。故选E项。
