选项 A、Contrast
B、Contrary
C、Compared
D、Comparison
答案 B
解析 篇章题。上下文理解题。选项contrary(to)表“与……相反”，如：Contrary to yoursuggestion，he did it alone．和你的建议相反，他独自做的这件事。文章后面提到dissenting voices(不同的意见)是对本句的回应，说明这种做法与以往的常规做法是不同的。因此，不论含义还是用法都与题意相符。contrast常用在in contrast to／with的结构中，表示“与……相比、对照”，如：Incontrast with his early works，the later paint—ings are brighter．与其早期作品相比，他晚期的画色彩更鲜亮。此选项在本句中用法错误。compare通常用于be compared to(把……比作)，如：Scientists sometimescompare the human brain to a computer．科学家有时将人脑比作电脑。此选项含义与题意不符。comparison为名词，意为“比较”，如：There is no comparison betweenthem．两者不可同日而语。由此可见，此含义和用法都不合本题。
