问题补充：

—What beautiful clothes you are wearing! They must be expensive.

—No. They only me fifty yuan.

A. cost B. spent C. paid for

答案：

解析：句意:-你穿的衣服真漂亮！他们一定很贵吧。-不，他们只花了我50元。这里是考查表示花费的几个词的用法。cost 花费，句子的主语应该是物；spend 花费，主语是人，常用于句型spend time/ money doing sth./ on sth. 花钱或时间做某事；pay for 为…付钱。根据句意可知，这里的主语they 指的是衣服clothes，故应该用cost。
