貌似你有点拼写错误哦
应该是succeed,successful,success
succeed是动词,变形是最一般的那种
successful是形容词
success是名词,如果意为成功,则不可数,例：Confidence is the key to success.如果意为成功人士或是成功事件,则可数.
succeed有以下几种用法
succeed in (doing) sth.
He succeeded in getting a place at art school.
succeed as sth.
He had hoped to succeed as a violinist（小提琴家）.
