介词besides,except,except for,but,apart from 和 in addition to 在用法上有何区别?besides 和 in addition to 同义,表示“除……之外(还)……”.但是,当与nothing,nobody或no one等否定意义的不定代词连用时,besides与except同义,表示“除…之外(其余都不)”.例如：
She knows Japanese besides English.
In addition to English,she knows Japanese.
All of them went to climb the mountain except me.
except 表示“除……外,(其余都)……”,常与“all,every,no,none,nothing”等含有整体肯定或否定意义的词连用.
except for：它的宾语与前述对象完全是两回事.例如：The room was very cold and,except for Jack,entirely empty.这个房间很阴冷,而且除了杰克,完全是空荡荡的.
Except：指同一类事物的总体中除去一部分.如：He gets up early everyday except Sunday.除星期天外,他每天早起.
Except that后面跟从句,语意与上同.如：He has always been in good health except that he has had a slight headache in the past few days.除了在过去几天里有些头痛之外,他身体一直很好.
But：常可与 except互换,强调“不在其中”.例如：Everyone attended the meeting but Mary.大家都出席了这次会议,但玛丽不在其列.
besides:强调“除此之外,还包括”.例如：She can speak French and Japanese besides English.除英语外,她还会讲法语和日语.
apart from；其含义主要依据上下文而定,有时可与except换用,有时可代替besides.例如：Apart from the cost,the hat doesn't suit me.除价钱太贵,这帽子也不适合我戴.
except 用于同类之间.
except for 用于不同类的.
apart from 在同类或不同类都能用
