对于细节题和理解、推理方面的题型，抓住题干中的中心词，找到其在文章中相对应的篇幅非常重要。例如第4题， 其中的中心词为the views of the Olmsted Brothers firm.用快速scanning的方法，集中注意力于出现这个词组的地方，在原文中很容易找到与题干中中心词相对应的 ″He and his brothers believed″ ，详见原文下划线处。
与题目对比
A They should be planted with trees that grow locally.
B They should provide a quiet restful environment.
C They should be protected by limiting the number of visitors from the community.
D They should be designed to conform to the topography of the area.
原文中提到了local topography the area＇s trees and shrubs escape from the city quite restful，唯独没有C项。所以答案很容易找出。
除了以上三点，掌握准确的定位方法对做题也是非常关键的。
