as good as和as well as区别如下：
1、用于本义，两者意为“与……一样好”，但 good 是形容词，而 well 是副词。
如：他说英语说得跟她一样好。
正：He speaks English as well as her.
正：His English is as good as hers.
2、用于引申义，两者的意思很不相同：
(1) as good as 意为“几乎”“差不多”(=almost)。
如：He as good as said I’m a liar.
他无异于说我撒谎。
习语be as good as one’s word意思是“说话算数”。
如：You’ll find that she’s as good as her word.
你能了解到她这个人很讲信用。
(2) as well as 表示“而且”。
如：She’s clever as well as beautiful.
她不但漂亮，而且聪明。
3、A as well as B=not only B but also A
该结构连接两个成分作主语时，其后谓语通常与前面一个主语保持一致。
如：Mary as well as her friends is going to Paris.
玛丽和她的朋友要去巴黎。
