as good as 和 as well as 的区别

1 “跟……一样好”
前者就是good的基本用法，后者就是well的基本用法（good是形容词，well是副词）
His car is as good as mine.
He did as well as me.
2 as well as 可以表示“也，和”，表并列关系

(is 是系动词） 她的裙子和我的一样好。 3. this book sells as well as that one.(well 修饰动词sell ) 这本书和那本一样好卖。 4. he speaks english as well as his teacher .　（well修饰动词speak） 他说英语和他老师一样好。
