核心问题
我是一个中专英语教师，对下面这句话一直没有弄明白：It reminded me of something I was taught as a young man.（中等职业教育《英语提高版》）教参上说 I was taught as a young man 是定语从句，而我认为是时间状语从句，省略了连词 when。
词典解答
只要搞清了 teach 的用法,这个问题就迎刃而解了。teach 是一个要求双宾语的动词: teach sb. sth. (参见 teach sb. sth. / teach sth. to sb.)。例如: He taught me Chinese. 当变为被动句时,直接宾语仍然保留下来,叫做保留宾语(见 retained object): I was taught Chinese by him.
在上面的句子里,保留宾语是 that: It reminded me of something that I was taught as a young man. 但是关系代词充当宾语时常常被省略。
