Question

请大家帮分析,这句中的one、 well 、and then各在里面起什么作用?啥成分?啥意思?
Over the years,one may well become an authority on one's hobby and will very probably be asked to give informal talks to little gatherings and then,if successful,to larger audiences.

Answer 1

one是主语,泛指“一个人；某个人”
well是副词,修饰become,作状语
and then其连接作用,意思是“而且”
