英语中except，except for,but和besides的用法区别

except ,besides,except for,but 之间的区别及例句
这四个介词或者短语都可以表示“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；but的意思与except接近，它主要与某些不定代词如nothing，all，anything， no one，anyone等连用。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。

一、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 colour 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 colour 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。
四、but的用法--"排除式"
but是"除了……以外"的意思,相当于except。
(1)but后也可以接名词或代词作宾语。例如:
1. They all went to the park ________ Mike and me.
A. besides B. except for C. but D. beside
析:Key: C。因为all是信息词,且they与Mike and me是"同类项",根据句意应选C。
(2)but常与下列词连用:a.否定词no one, none, nothing等; b.疑问词who, what等; c.不定代词all, everyone等。例如:
1. Nothing but disaster would come from such a plan.这个计划只能招灾惹祸,别无益处。
2. Who but Tom would do such a thing?除了汤姆以外还有谁愿意干这种事?
(3)but后可接动词不定式。注意:当but前面有实义动词do以及其相应形式作谓语动词时,则其后跟不带"to"的动词不定式,反之加"to"。例如:
1. David could do nothing but ________ his teacher yesterday afternoon.
A. help B. helped C. helping D. to help
析:key:A。do nothing but...后应接动词原形,意为"除做……外什么也不做"。
注意:but for是"要不是;没有……"的意思,常用于虚拟语气。例如:
But for your help, I would have failed. 要是没有你的帮助, 我早就失败了。
此外：apart from也可表示此意，其用法相当与besides, except for
