四级阅读部分解析
Passage One
本文节选自BBC NEWS网站Science & Environment板块，一篇名为Green spaces have lasting positive effect on well-being的文章。文章指出居住在环境更为绿色健康的社区对人有持续的积极作用。研究发现，不同于升职加薪，结婚或者中彩票这类事件给人带来的短期的快乐，居住在一个好环境给人带来的积极影响可持续三年以上。人们的健康和好的环境密不可分，但是对于政府来说麻烦的是找到资金来源，建立一个高质量的绿色社区。
文章后题目主要考查事实细节，同样根据出题的顺序原则，找出题干中的关键词如Dr. White，government等，再返回原文进行定位, 一些题目选项跟原文有一定的出入，需要仔细甄别得出答案。
46.[B] Add to their sustained happiness.
本题对应原文首段中UK researchers found moving to a green space had a sustained positive effect. 又根据第一段的意思可得出居住在绿色的环境里会使人更加的快乐，故得出答案。
47.[A] Earn more money.
本题对应原文首段中Mathew White所说的话中“ for example people do all sorts of things to make them happier: they strive for promotion at work, pay rises, they even get married. ”由此推导出答案。
48.[C] How long its positive effect lasts.
又第一段可知如升值、加薪、中彩票只会给人们带来短期的快乐，这种快乐在过了六个月到一年后就会消失，并根据第二段首句“Dr White said his team wanted to see whether living in greener urban areas had a lasting positive effect on people's sense of well-being or whether the effect also disappeared after a period of time.”可推导出Dr. White想要知道居住在绿色环境中给人带来的积极的影响可以持续多久。
49.[D] Their communication with others improved.
根据原文中第三段最后一句话"There is evidence that people within an area with green spaces are less stressed and when you are less stressed you make more sensible decisions and you communicate better" ，最后的communicate better可推导出答案D。
50.[A] Find financial support
文章中最后一段讲的是我们需要资金来建立一个高质量的绿色社区。答案也可根据最后一句话推导得出“what we really need at a policy level is to decide where the money is going to come from to help support good quality local green spaces. ”
