英语中的but 与except的问题

答案是except
关于 but 与 except两者都可表示“除…外不再有…”,但含义上略有差别：but侧重指意义的几乎完整性,而 except 则侧重指后面除去的部分：All are here but one.除一个人外大家都到了.All are here except one.还有一个人没到.还有一个人没到.另外,在现代英语中,but 的介词用法十分有限,一般说来,它只能用在下列词语之后：① no,no one,nobody,nothing,nowhere 等② any,anyone,anybody,anything,anywhere 等③ every,everyone,everybody,everything,everywhere 等④ all,none 等⑤ who,what,where 等Everyone knows it but you.除你之外大家都知道.I haven’t told anybody but you.除你之外,我没告诉任何人.No one but he [him] showed much interest in it.除他之外没有一个人对此有很大兴趣.但是 except 却没有以上限制：正：The window is never opened except in summer.除夏天外,这扇窗户从不打开.
误：The window is never opened but in summer.
而这题中,是强调我没有被邀请

expect 是除了（不包括在except 后的主语）
翻译成为：MILLIE 除了我，我班的学生都被邀请了。
But 是转折关系
