He did not + 普通动词的原形（如 know,like,play,see）
He did not know + what/ when/ where/ which/ who/ how/ whether + to + 普通动词的原形或助动词 be
He did not know + why/ if/ that + 从句
再问：我的意思是这个从句用什么时态？
再答：从句中可以用一般过去时、过去进行时、过去完成时，或过去完成进行时：

He did not know I was there.
He did not know that I was listening.
He did not know what had happened.
He did not know if she had been studying or sleeping.
再问：这意思是从句不能加have done？
再答： He did not know 是一般过去时的否定，所以和一般过去时、过去进行时、过去完成时，或过去完成进行时连用。

He does not know 是一般现在时的否定，所以和一般现在时、现在进行时、将来时、现在完成时，现在完成进行时，或将来完成时连用：

He does not know I work.
He does not know that I am working.
He does not know that I am going to visit him tomorrow.
He does not know what I have done.
He does not know what I have been doing.
He does not know what will have happened.
