11---15．ACBDB
11．A   联系上下文  根据下文"They（17）the metal health of hundreds of Britons who had moved from a grey city neighborhood to a greener one with（18）who had moved oppositely．"提到了研究的对象是：居住在不同环境中的众多英国居民的幸福状况，因此排除B．C．两项；此处的意思应是：中高收入国家近百分之80的人口；folk意为：民族，人们；故选A．
12．C   考查句意理解及非限定性定语从句    本句为非限定性定语从句；意思是：在中高收入国家，近百分之80的人口生活在城市，在那里，主要担心的是公共健康问题；此处在从句中作地点状语；故选C．
13．D   考查句意理解    由于本句的主语Parks，gardens and natural（13）之间是并列关系，故此处指的应像公园，花园等类似的自然生态环境；故选D．
14．A   考查句意理解    根据句中的主语Some studies以及"that there is a relationship between green space and（15）"表述的是研究结果，可知此处的意思应是：一些研究表明；故选A．
15．C    联系上下文   根据下文"they found that people who had moved to a greener area were happier-and stayed happier-after their move．"他们发现搬到更绿色环保地区的人会更快乐或在他们搬家后感到更快乐，可知此处指的应是：绿色空间与幸福快乐的关系；故选C．
16---20．ACDAC
16．A    考查句意理解   此处指的是：Mathew R．White 与来自埃克塞特大学的同事；故选A．
17．C     考查句意理解    本句的意思是：他们将从灰色的城市街区搬到一个更绿色环保地区的英国人与那些搬到相反地区的人的心理健康状况进行了比对；此处的compare…to…意为"将…与…进行比较"；故选C．
18．D    考查不定代词    A．others泛指"其他的人或物"； B．ones 表示泛指同名异物； C．all 指所有的人或物；D．those表示特指，相当于the ones；此处特指的是：那些搬到相反地区居住的英国人；故选D．
19．A   考查固定短语      over the course of…意为：在过去的…；故选A．
20．C    考查上下文句意理解及名词词义辨析   A．calculate 计算； B．imagine设想，想像； C．conclude作结论，得出结论； D．doubt怀疑； 根据下一句"Environmental policies to…may have continuable public health benefits．增加城市绿地的环境政策对于公众的健康有益处"可知，此处指的是研究人员经过研究得出的结论；故选C．
