except与except for的区别
（1）except表示“除去，不包括”，强调所排除的“不包括在内”，一般表示同类之间的关系，常同nothing, all, none, nobody, any等不定代词以及every连用。except 经常接名词或代词，但也可接副词，介词短语，例如：
① The office is open every day except Sundays. 除了星期日这家公司每天都营业。
② You can have any of the cakes except this one. 除了这块蛋糕，你哪块都能吃。
橙子的作用③ She saw nothing except snow. 除了雪她什么也没看见。（nothing except = nothing but = only）
（2）except经常接名词、代词，也可接副词，介词短语，不带to的不定式或从句等。例如：
④ She looked everywhere except here. 除了这里，她到处看。
⑤ You may drop in at any time except at noon. 除了中午，你任何时候来都可以。
⑥ She doesn’t do anything except sit and watch TV. 除了坐着看电视外，她什么也不做。
⑦ It was a good hotel except that it was rather noisy. 这家旅馆还不错，只可惜吵。
⑧ He usually goes to work by bicycle except when it rains. 除了下雨的时候，他通常骑自行车去上班。
（3）except for也表示“除…以外”，指对某种基本情况进行具体的细节方面的修正。它同except的区别是：except for后接的词同句子中的整体词（主语）不是同类的，指从整体中除去一个细节，一个方面；而except后接的词同整体词（主语）一般是同类，指在同类的 整体中除去一个部分。例如:
⑨ I can answer all the questions except for the last one. 除了最后一题外，所有题目我都可以解答。
⑩ Your writing is good except for a few grammar mistakes. 除了几处语法错误外，你的作文写得很好。
except,besides,except for用法的关联和区别
1. 作介词用法时,这三个词都有"除…之外"的含义,但except常与do／does／did／have／has／had nothing等词形成搭配用法,或者与全部肯定词all、everything、ev eryone等连用,或者与全部否定词nothing、 nobody等连用,因此except加宾语作介词"除…之外"时常表示从整体中剔除一部分；而besides作"除…之外"时则表示"另外附加"的含 义,相当于"in addition to"。试比较下列例句:
1)He did not hing except watch TV yesterday.
2)He said nothing except to smile just now.
3)All the students took at rip except Tom yesterday.
4)We need 3 more persons to finish the job besides／inaddition to us two.
2.作介词用法时的except后可接多种情况的介词短语。在这种情况下,except后的介词是不可省去的,except加介词的实际作用就相当于连词加相关的从句。例如:
亿力高压清洗机
1)The weather is fine today except in the northwest.此句相当于:
The weather is fine today except that it is in the northwest.
2)His mother never takes any exerci except on the dance floor.此句相当于:
His mother never takes any exerci except that she has adance on the floor.
需要强调的是except与exceptfor的用法区别:
1)Except后排除的内容与主语往往是同一类的,而exceptfor后所排除的内容与主语往往不是同一类的。例如,试比较:
All the buildings are excellent except this one.
All the buildings are excellent except for their location或者All the buildings are excellent except that the place on which the buid ings are built is notgood.
2)当except用在句首时往往改用exceptfor。例如:
There was no single person in the dark street that night except apoliceman on his duty.此句相当于:智慧的近义词
面相图Except for apoliceman on his duty,there was no single person in the dark street that night.

3.相当于连词用法的except与相当于连词用法的besides的区别仍然保持它们作介词用法的含义。试比较下列例句:
1)Tom is a good student ex cept that he is careless.此句相当于:Tom is a goods tudent except for his carelessness.
2)Tom ldom comes late to school except when it rains hard.此句相当于:Tom ldom comes late to school except on a heavily rainy day.
