高人请进!区别一下几个单词或词组!

都可以表示“除了…”的意思.但except仅表示“除了…”,排除在外,后面可以接that,what,when等引导的从句；而besides表示“除了…还有…”的意思,表示包含在内；except for表示“除了…”,它引出一个与前面的词相反的原因或者事例；apart from 表示“除 …之外”.根据上、下文的不同,它既可用作 besides, 也可用作 except 和 except for.例如:
Apart from them, I had no one to talk to. （= except）
除了他们以外, 我没有人说话.
Apart from other considerations, time is also a factor. (=besides）
除了别的考虑之外,时间也是一个因素.
(It is) Good work apart from a few slight faults. (= except for）
除了几个小毛病以外,这是一篇佳作. 例如：
"Except for one old lady, the bus was empty."
公共汽车上要不是坐了一位老太太就是空的.
She can do everything except cook.
除了做饭之外她什么都会.
He had considered everything except the weather.
"他什么都想过,唯独没考虑到天气."
I know nothing about it except what I have read in the papers.
"除了在报上读到的以外,我对这件事一无所知."
Most of the Chinese people usually go to work on the bike except when it rains.
"除了雨天,大多数中国人一般都骑自行车上班."
Besides milk and cheese, we need vegetables.
除了牛奶和干酪外,我们还需要蔬菜.
Besides football, I like playing basketball and table tennis.

EXCEPT, 除了………………以外。(简单理解，都行，除了这个不行）WE ARE ALL GOING ,EXCEPT HIM
EXCEPT FOR ……………………（简单理解都不行，除了这个行）。It can not be done. except for this situation that^^^^^^^
BESIDES， 和apart FROM 意思一样，用法有差，
