参考答案

正确答案：D
解析：本题考查事实细节。题目的问题是“文章为什么要提及Janet Reno和Michael J．Fox”。文章第三段第一句：As its 19th—century name suggests--and as many people know from the educational efforts of prominent Parkinson’s sufferers such as Janet Reno，Muhammad Ali and Michael J．Fox—the disease is characterized by movement disorders．根据这句话可以知道他们是众所周知的帕金森病患者，所以D项符合题意。
