【题目】To improve the quality of our products, we asked for suggestions _____ had used the products.

A. who B. whoever

C. whichever D. which

【答案】B

【解析】

试题分析：考查连词的用法 句意：为了提高我们产品的质量，我们征求了用过的人的建议。这里是宾语从句，ask sb for suggestions,这里缺sb,就用代词whoever来代替。ask sb for suggestions是动词词组在整个句子中，who侧重于指事情，whoever="anyone" who侧重于指人，故选B。
