Question

To improve the quality of our products, we asked for suggestions        had used the products.

A．whoever

B．who

C．whichever

D．which

Answer 1

A

试题分析：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 suggestiongs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A。
点评：本题难度适中。判断宾语从句中用哪个连词，需用记住连词的用法，在句中的作用，连词也是高考的热点，需要考生平时多练习。需要考生会分析句子成分理解句意。这里考生容易误选B。

A.that; when               B.which; that
C.that; before             D.which; when
解析：A。考查when表示“那时”的用法。根据句意，选A。
