答案

C 译：当你心情不好时,你可以跟你父母谈谈.
这里副词when+现在分词就等于由when引出的时间状语从句.这一结构用语法术语说就是：带有引导词的分词结构,其用法是：引出状语从句的副词后面的逻辑主语与主句的主语一致,且表主动时用现在分词,表被动时用过去分词.又如：
While crossing the road,he met his friend.他过马路时,遇到了他的朋友.
Though having little time,he tried to fninsh the task on time.尽管时间很少,他还是准时完成任务了.
When taken to the hospital,he had lost his conscionsness.当被带到医院时,他已失去知觉.
