He apologized to her for not going to her party..为什么不能把NOT换成didnt？？？可以么？？

He apologized to her for not going to her party. 由于没有出席她的聚会,他跟她道了歉.
not否定going, didn't 后面就要跟动词原形了.如下

He apologized to her for he didn't go to her party.

I haven't = I have not+ppv. 现在完成时的否定
I don't have 一般现在时的否定

不可以，，一个完整的句子中不可能有两个谓语动词，，did是do的过去式，do是助动词

一般have的否定在是在前面+don't/doesn't/didn't
可是当have作为"拥有"的意思或做完成时态的助动词时可以用haven't/hasn't/hadn't
don't have, doesn't have, didn't have 是美式英语
haven't, hasn't , hadn't是英式英语

希望对你有用。。

不可以，因为apologize for sth，后面要加名词或者动词ing结构；
I havent是我没有，I dont have是我没有吃...
比如说I havent a watch和I dont have dinner.意思是不一样的。

还是不可以，因为do是动词，这里句子成分已经完整了，for 也可以是his not going to her party，但是动词已经有了，apologize for sth是固定搭配

apologize to sb. for doing/ not doing 因此不能用didnt
I haven't 是现在完成时态 have not 的缩写 后面要加过去分词
I don't have 指 我没有
