C
附：except与 except for 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。
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。

此题选 C
except的用法--"排除式"
except意为"只有……除外;除去……",后跟名词或代词作宾语,强调从整体中除去部分,即except后的部分不包括在整体之内。因此,常和all, everything, no one, nothing等词一起使用。其判别标志是:除去的与保留的是"同类项"。例如:
1. All of them went out for a walk ________ John.
A. besides B. except C. beside D. excepts
2. Everyone is here ________ Xiao Wang and me.
A. except B. besides C. beside D. excepts
析:Key:1. B 2. A。因除去的与保留的是"同类项",且1、2题中有信息词All、Everyone。
二、except for/that的用法--"排除否定式"
except 除后跟名词、代词作宾语外,还可跟介词,也可跟从句。
(1)except for...是"除了因为……;要不是……;除去……一点外"的意思,表示"对一个人或事物,先做一个整体评价,然后再就局部提出一点看法"。即一部分被肯定,另一部分被否定,这就是所谓的"排除否定式"。其判别标志是:除去的与保留的"不是同类项"。例如:
1. It was dark in the city ________ a few weak lights.
A. except for B. except C. besides D. but for
2. Your composition is very good ________ a few spelling mistakes.
A. except that B. except for
C. besides D. beside
析:Key: 1. A 2. B。因为除去的与保留的"不是同类项",故选except for。
(2)except that... 也是"除去……一点外"的意思,但应注意恰当地使用引导词。若从句句意和结构完整,只需用引导词that。例如:
1. The suit fitted him well ________ the color was a little brighter.
A. except for B. except that
C. except when D. besides`
析:Key: B。本题题意为"除色彩艳了一点儿外,这套衣服很适合他",从句the color was a little brighter句意和结构完整,只需用引导词that,故选except that。
2. -Can you tell me all about the earthquake?
-Sorry, I know nothing about it ________ I read in the newspaper.
A. except B. except for
C. except what D. except that
析:Key: C。因从句中read为及物动词,且其后无宾语,故选except what。
3. Mr Green usually goes to work by bus ________ it rains.
A. besides B. except when
C. except what D. beside
析:Key: B。由于it rains为从句,故排除A、D,且rains为不及物动词,不需要宾语,故排除C。except when 意为"除了当……的时候"。
(3)except for与except that有时可互相转换。例如:
1. Your composition is very good except for a few spelling mistakes.
=Your composition is very good except that there are a few spelling mistakes.
2. The village is very quiet except for some birds singing in the woods.
=The village is very quiet except that there are some birds singing in the woods.
三、besides的用法--"包括式"
besides相当于as well as,意为"除了……以外还有……",即"除去一部分还有另外一部分"的意思,表示besides 后面的部分包括在整体之内。例如:
1. Does John know any other foreign language ________ French.
A. except B. but
C. besides D. beside
析:Key: C。由本题中的信息词"any other foreign language",可知选besides。

C except+A 除了A （不包括A）besides 除了A以外还有..(包括A)except for 除去美中不足的一部分 小瑕疵例如 Your composition ‘s really brilliant except for few mistakes您的支持就是我继续前行及帮助别人的动力...
