有一读者问这样一句话：
(1)He takes the analytic tools that zoologists typically use to study animals and applies them to the study of humans.
应如何理解这句话？
这句话的意思是：他采取动物学家研究动物所常用的分析法并运用到人类研究中。你可能对 tools 一词感到困惑。 tools 在此不意谓具体的工具，而是意指“手段，方法”，再如：
(2)Textbooks became the essential tools of the teacher.
(3)We will investigate written tests as one of several assessment tools for children of different ages.
又， typically 的本义是“典型地，有代表性地”，但有时可简略地译之为“常”。
