realized,后面began有提示一般过去时.
你有这样疑问,是因为看到after后面有时候直接加动词ing形式么~或者句子可以根据意思这样理my son began to cry after he realized he had made a mistake .after 后面是一个介宾短语.
当after后面直接跟动词时,动词ing形式.或者动词作动名词时候也是.

考查一般过去式和过去完成时。分析一下：realize意识到,had made mistake为过去完成时（发生在过去的过去）而意识是在发生后有的，所以要退回一个时态，用过去式。记得意识发生在过去，而犯错误在意识之前，过去的过去。

realized 认识到

realized
此处是after 后接从句，
从句的时态就看实际发生在什么时候
这里很明显是一般过去时
