good一般用作形容词
修饰名词:You did a good job.
接感官动词: That sounds good.
或作表语:It looks good.
重要的是区分good和well是可以转化的 但前提是good是形容词 well作副词.
eq:You did a good job/You did the job well.
还有一些时候well作特殊词性:形容词使用.
比如,在看病时:Are you feeling well?
同时 good和well的比较级都是better *都是best.
如果更复杂一点 就是说要区分感官动词和系表结构.
感官动词使用:I’m feeling well/I'm feeling better.
