女生读职高什么专业好:高二英语语法

except和 except for如何区别?

一、 except用于表示同类事物之间的关系，其意为"除......以外"、"除去"。

except后面可接名词、代词、动词、副词、介词短语和从句等。如：

We have an English lesson every day except Sunday. 除星期天外，我们每天有一堂英语课。（接名词）

They all went to the park last Sunday except him. 除了他以外，上星期天他们都去公园了。（接代词）

Every day Mary does nothing except watch TV. 每天玛丽除了看电视以外什么都不干。（except后接动词时，一般为带to的动词不定式。但如果except前面有谓语动词do或其相应形式时，后面通常接省略to的动词不定式。如此句。）

He always goes to work by bike except recently. 除最近外，他一般都骑自行车上班。（接副词）

After breakfast the students went nowhere except to school. 吃完早餐，学生们除了上学就不到别处去了。（接介词短语）

My father usually goes to work by bike except when it rains. 除下雨天外，我爸爸通常骑自行车上班。（接从句）

二、 except for用于表示对主要部分的肯定和对局部的否定。它不表示同类事物之间的关系，其意思为：

1. "除了......以外"。如：

Smith is a good man, except for his bad temper. 史密斯除了脾气不好外，是个好人。

The movie was good except for the ending. 这部电影除了结尾之外都很好。

2. "除去为了......"。如：

Mother wouldn't give him any money except for books and stationery. 除了买书和文具外，妈妈不给他任何钱。

3. "如果不是"，"若非"。如：

Except for you, I would pass the exam. 如果不是你，我就会通过考试。

4. "except for+名词"结构一般可以改写成"except+that从句"。如：

This will do except for the length.= This will do except that it is too long. 如果不是它太长的话，这会很好。

All are here except for the absence of Tina. = All are here except that Tina is absent. 除了蒂娜以外，大家都在这里。

三、 except与except for的互换

1. except与except for有时可以通用，不过，一般情况下，except for可置于句首，而except则不能。如：

Everyone is here except Tom. （或：Except for Tom everyone is here.）除汤姆外，大家都到了。

2. except与except for在句中也可互换。

一般来说，否定句中用except，肯定句式可以用except for来替换。如：

This article has no blunders except a few mistakes.这篇文章除了一点小错外没有大错。

此句可改为：This article is instructive except for a few blunders. 这篇文章除了有些错误外，是有教育意义的。

不过，在前后有相称的同类词语时，应用except，否则用except for。如：

We come to school every day except Sunday. 除星期天外，我们天天上学。（句中every day与Sunday同类）

This dress is ready except for the buttons. 衣服做好了，只是钮扣未缝上。（句中ready与buttons不同类）

except 表示同类之间的比较，不可放在句首
except for 表示不同类之间的比较，或整体与个体的比较，可放在句首

其实，except, except for/that, besides都有"除……之外"的意思,但用法各异,现就它们的用法进行分析比较:

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 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。
