Except,but和beside的区别

Except,but和beside的区别
要详细,有例句,最好每种情况一个例句.

esides,except,but的用法区别
1.基本区别三者均可表示“除了”,但 besides 表示一种累加关系,意指“除了什么之外,还有…”；而 except 或 but 则表示一种排除关系,意指“除了什么之外,不再有…”：Besides his wife,his daughter also went to see him.除他妻子外,他女儿也去看过他.You can park anywhere except [but] here.只有这里不能停车.但是,在否定句中,besides 也表示“除…… ”,与but,except 同义：
No one passed the exam besides [except] Jim.除吉姆外,没一个人通过考试.
2.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.
3.关于 except 与 except forexcept 主要用来谈论同类的东西,而 except for 则主要用来谈论不同类的东西,有时含有惋惜之意：All compositions are well written except yours.除了你的作文外,其他的作文都写得很好.His composition is good except for a few spelling mistakes.他的作文写得不错,只是有几处拼写错误.若用于句首,则 except for与 except 同义(但 except 通常不用于句首,另外but也不能用于句首)：
Except for me,everyone passed the exam.除了我之外,大家都通过了考试.
