expect和expect for的区别

except,except for用法的关联和区别如下：

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／hadnothing等词形成搭配用法,或者与全部肯定词all、everything、everyone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；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:

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 exercise except on the dance floor.此句相当于:

His mother never takes any exercise 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:

Except for apoliceman on his duty,there was no single person in the dark street that night.

同学，你好，应该是：except for，你两个单词都写错了

except 后可跟从句、名词词组、介词词组等多种结构。except for 只能接名词词组，该名词所表达的概念与句子的主语名词概念不属于同一范畴。

（ ）a few cars, the street was almost empty.
A. expect B. besides C.except for

"有for指后者是前者一部分
例如: Nobody in our class is late except for Tom.(Tom是我们班的一个人)
如果后者不是前者一部份 即前者不包括后者 就不用for"
