剑10P19 Q8 Who are frequent visitors to stepwells nowadays? 

大家理解题意难度不大，但不少学员却迟迟找不到答案。一来此题貌似无明显关键词定位需要通读原文，二来此题在原文的位置与上一题相隔了5段之远。但其实这道题目是送分题，题干中出现了“nowadays”这个单词，需要引起大家的重视。在我平时的授课过程中会训练学员提前读段首句的能力，“今昔对比”结构则是平时训练的重中之重。绝大多数学员在读段首句时都能标记出最后一段段首句中的“today”,从而为完成此题做了充分准备。其实，这种考法并不新鲜了。

大家可以试一下，原文如下：Although Perkin’s fame was achieved and fortune assured by his first discovery, the chemist continued his research. Among other dyes he developed and introduced were aniline red (1859) and aniline black (1863) and, in the late 1860s, Perkin’s synthetic dye discoveries had outcomes far beyond the merely decorative. The dyes also became vital to medical research in many ways. For instance, they were used to stain previously invisible microbes and bacteria, allowing researchers to identify such bacilli as tuberculosis, cholera, and anthrax. Artificial dyes continue to play a crucial role today. And, in what would have been particularly pleasing to Perkin, their current use is in the search for a vaccine against malaria.
