50. According to Dr. White, what should the government do to build more green spaces in cities?
- A. Find financial support.
- B. Improve urban planning.
- C. Involve local residents in the effort.
- D. Raise public awareness of the issue.
答案：A
答案句：With a growing body of evidence establishing a link between urban green spaces and a positive impact on human well-being, Dr. White said, “There's growing interest among public policy officials, but the trouble is who funds it. What we really need at a policy level is to decide where the money will come from to help support good quality local green spaces.”
参考译文：随着越来越多的证据表明城市绿色空间与人类福祉之间的积极联系，怀特博士说：“公共政策官员的兴趣越来越大，但问题是谁来资助。我们在政策层面真正需要的是决定资金从哪里来，以帮助支持高质量的当地绿色空间。”
定位线索：题干“what should the government do to build more green spaces”→答案句“who funds it”“where the money will come from”；文中“funds”“money”对应选项A“Find financial support”。
解析：题干问政府应该做什么来建设更多绿色空间，答案句指出问题在于“who funds it”和“where the money will come from”，即需要解决资金问题，对应A选项“Find financial support”。B选项“urban planning”、C选项“involve local residents”、D选项“raise public awareness”在原文中均未提及，属于无中生有。
