提示：考试采取"多题多卷"模式，试题顺序不统一，请依据试题进行核对。
56.原文第一段第一句反问句“Could you reproduce Silicon Valley elsewhere, or isthere something unique about it?”可得知答案选A——Its success is hard tocopy anywhere else. 选项copy同义改写原文的reproduce。
57.由题干大写字母Miami定位到原文第五段“Few startups happen in Miami, for example,because although it’s full of rich people, it has few nerds. It’snot the kind of place nerdslike.”由因果关系词because找到原因——这里既是有很多富裕的人，却几乎没有nerds（痴迷科研的人）。所以答案选B——Lackof the right kind of talents.
58，由题干大写字母Carnegie-Mellon, MIT, Stanford,Berkeley等定位到第六段，问CM和其他的是哪里有不同。“The top US Computer Sciencedepartments are said to be MIT, Stanford, Berkeley, andCarnegie-Mellon. MIT yielded Route 128. Stanford and Berkeleyyielded Silicon Valley. But Carnegie-Mellon? The record skips atthat point.”原文讲到了MIT, Stanford, Berkeley都yielded产生了很有名的sciencedepartment，而Carnegie-Mellon呢？这个记录可以直接跳过忽略。言下之意就是CM没有出名的sciencedepartment，所以答案选D——It does not pay much attention to businessstartups.
59题，由题干大写字母Boston定位到倒数第二段。定位句“The weather is terrible, particularlyin winter, and there’s no interesting old city to make up for it,as there is in Boston”说到了Boston是一个无聊的老城市，而定位句的下一句“So while thereare plenty of hackers who could start startups, there’s no one toinvest in them”说到了这样的城市无法吸引投资。所以答案选C——It is not likely to attractlots of investors and nerds.

61题，定位到第一段最后一句“varies byculture”，所以答案选A——They areculture-related.
62题，由题干的大写名词Russian定位到第二段和第三段。第二段的“Russian, for example, began towake up about a half-hour later each day”这一句是干扰句，起得晚不一定睡得早，所以答案推不出“他们比其他地方的人睡得更久”。然后看到第三段“Russia’sother late nights and early mornings generally coincided withpublic holidays”，所以答案为C——They don’t sleep much onholidays。
63题，题干问的是欧洲人缺乏睡眠的major cause主要原因是什么，由题干的大写名词Europeans’loss定位到倒数第二段的“comparedto Germans, Italians, and the French, who stayed up around an hourand a half later on
