问题 The new laundry detergent products have been______tested by our researchers, so they are perfectly safe for customers to use.
选项 A、hardly
B、thoroughly
C、exceptionally
D、previously
答案 B
解析 选项都是副词，因此是根据句子内容选择合适的副词的题。空格后是“经由我们的研究人员检验”的被动语态结构，空格处适合完整句子结构，填副词thoroughly合适，用于修饰动词tested。另外，thoroughly常和research，examine，inspect，test，review，go over等一起使用，修饰和“调查／研究／检查／检讨”相关的动词。
