论文As的用法详解，本文是的用法详解专升本论文范文和用法和详解方面论文怎么写.
一、作副词,意为相同地,同样地.例如：
They don’t he as many airplanes. 他们没有同样多的飞机.
二、作连词
1. 引导时间状语从句
as 与when,while 都是引导时间状语从句的从属连词,含义都是；当……的时候,但它们有区别:
when 作当……的时候解,可以指较短的时间,也可指一段时间.从句的动作可以与主句的动作同时发生,也可以先于主句的动作发生.例如:
John was hing his dinner when I saw him. 当我看到约翰的时候,他正在吃饭.
She can write only when the baby is asleep. 只有婴儿睡着的时候,她才能写作.
while 常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生或在从句动作过程中发生.例如:
We must strike while the iron is hot. 要趁热打铁.
While we were reading, the teacher came in. 我们正在读书的时候,老师走了进来.
但属下列情形时,只用as, 而不用when 或while.
① 用于表示同一个人的两种动作交替进行,指一边……,一边…….例如:The girl dances as she sings on the stage. 那个女孩在舞台边唱歌边跳舞.He looked behind from time to time as he went forward. 当他朝前走时,不时地向后看.
② 表示两个同步发展的动作或行为,译为随着…….例如:
As time went on / by, she became more and more worried. 随着时间的流逝,她变得越来越焦虑.
As he grew older, he became more intelligent. 随着他年龄的增长,他变得更有才智了.
③ 表示两个短促行为或事件几乎同时发生.例如:
I thought of it just as you opened your mouth. 恰好在你开口时,我想到了它.
Just as the flying worm hit her face, she ge a loud cry. 恰巧在飞虫撞到她脸上时,她大哭起来.
2. 引导原因状语从句
as,because,since 都可以表示因果关系,连接原因状语从句,含义是因为,由于,但它们有区别：because 表示的语气最强；as 一般放在句首,语气较弱,较口语化；since 常常用在书面语中,表示多为对方已知的、或稍加分析便可得知的原因,有时可译作既然.例如：
I do it because I like it. 我做这件事是因为我喜欢.
Since many of the customers work during the day, Billy has to collectthe money at night. 因为许多顾客白天上班,所以毕利只好晚上去收钱.
As she has been ill perhaps shell need some help. 她由于生病可能需要些帮助.
3. 引导让步状语从句
as 与although ,however 等都可以引导让步状语从句,含义是虽然,尽管,但它们有区别：although 语气稍正式些,可放在句首,也可放在句中,主句中不能再用 but,但可以用yet ；as 所表示的语气较强,引导的让步状语从句用倒装语序；however 引导让步状语从句时,它的后面可跟形容词或副词,也要用倒装语序.例如：
Although they are poor they are happy. 虽然他们很穷,但很快乐.
Angry as he was, he managed to speak calmly. 虽然他很生气,但是他讲话很平静.
However hard the question is, he can answer it. 不管问题有多难他都能回答.
注意：当as 引导让步状语从句时,句子的倒装语序有以下三种形式：
形容词或副词+as+ 主语+ 连系动词be 或实义动词.例如：
Rich as he is, he never spends a cent on clothes. 虽然他很富有,但他从不花一分钱在衣服上.
Much as I admire his courage, I don’t think he acted wisely. 我虽然佩服他的勇气,但我认为他这样做是不聪明的.
名词+as+ 主语+ 连系动词be .例如：
Child as he is, he knows a lot. 尽管他是个孩子,但懂很多事情.
Boy as he was, he was chosen king. 尽管他还是个孩子,但却被立为国王.
实义动词+as+ 主语+ 助动词[ 如果没有助动词,则要加上一个do].例如：
Try as he may, he never succeeds. 尽管他很努力,但总是不成功.
Change your mind as you will, you will gain no additional support. 即使你改变主意,你也不会得到另外的支持.
4. 引导方式状语从句,意为如,像,按照……的方式.如:
I want you to tell my friend your very interesting experience exactly asyou he told it to me. 我想让你像给我讲述的那样,给我的朋友讲一讲你那段极其有趣的经历.
Remember, you must do everything as I do. 记住,你必须按照我做的那样做一切.
注意：like 在非正式语体中可以有与as 相同的用法.如：
I can’t sing like I used to. 我不能像以前那样唱歌了.
He writes just like his brother did when he was young. 他现在写文章正像他哥哥年轻时写文章一样.
5. 引导比较状语从句,用于as…as…或 not so/ as…as…中,前一个as是副词,后一个as 是连词,意为如……一样.如:
You hate her as much as I .
I don’t speak English so/ as well as he does.
注意：句中连词as 后面的代词实际是省略了与主句相同的部分,即可以写成You hate her as much as I hate her. 如果很明显就能看出所省略的部分,意义不会含糊不清时,在口语中也可以用代词的宾格形式.例：At your ageyou can’t expect to play footballas well as me . 但例就不能改I 为me,改后意思就变为：You hate her as much as you hate me. 你恨她像恨我一样深；而原句的意思为：你恨她像我恨她一样深.
三、作代词as 作关系代词的用法
关系代词as 引导定语从句时,既可以单独使用,也可以与其他词连用,其用法要比that 和 which 更为复杂.
1. as 引导定语从句与其他词连用
用于the same…as 结构中
This is the same watch as I he lost. 这块手表跟我丢失的那块一样.
用于such…as 结构中
I don’t like such novels as you recommend. 我不喜欢你推荐的那些小说.
用于；so +adj. + a/an + n. + as ；结构中
I am not so strong a man as I was. 我已经没有从前那么强壮了.
2. as 单独引导定语从句
as 单独引导定语从句时,先行词可以是一个词,也可以是一个句子或短语.例如：
She is late, as is often the case. 她迟到了,这是经常的事.
To shut your eyes to facts, as many of you do, is foolish. 对事实视而不见——你们好多人都是如此的愚蠢.
注意1 ： 当as 引导的定语从句位于具有否定意义的主句之前时,as 从句所修饰的范围是整个主句的内容,也就是说,把否定意义也包括在内.例如：
As has been said above, grammar is not a set of dead rules. 正如前面所说,语法不是一套死条文.
当as 引导的定语从句位于具有否定意义的主句之后时,as 从句所修饰的范围不包括否定意义.例如：
Spiders are not insects, as many people think.
等于 Spiders are not insects. But many people think they are. 许多人认为蜘蛛是昆虫,但蜘蛛并不是昆虫.
当as 引导的定语从句位于具有否定意义的主句中间时,as 从句所修饰的范围也不包括否定意义.例如：
She did not, as her friend had feared, open the case. 她没有打开盒子,而她的朋友就是怕她当面打开盒子.
注意2: 当修饰句子的非限制性定语从句位于句尾时,as 可以用which 来替代.
例如:I live a long way from work, as you know. 我住得离工作单位很远,这你是知道的.
但是,当as 从句位于句首或句中是,as 就不能用which 来替代了.例如：
As you will find out, I will never let you down. 你将会发现,我绝不会使你失望的.Taiwan is, as you know, an inseparable part of China. 你们知道,台湾是中国不可分割的一部分.
此外,如果主句为否定句,则位于句末和句中的as 从句所修饰的范围并不包括主句的否定意义,此时,as 也不能用while 来替代.例如：
Greenland was not a continent, as people thought. 格陵兰并不像人们所想象的那样是一个大陆.
四、作介词1. 表示 好像,例如:
They entered the building disguised as cleaners. 他们伪装成清洁工人的模样进入大楼.
2. 表示作为,当作,例如：
I found a job as a teacher. 我找了一份教师的工作.
3. 表示当某人是时.例如：
As a child, she was sent to three different countries. 她儿时去过三个不同的国家.
4. 表示因某人是,例如：
As her private secretary he has access to all her correspondence. 他是她的私人秘书,能接触到她所有的信件.
注意1 ：as 引导的介词短语大多用作状语,as 译为“作为”,少数情况可引起宾语补足语.例如:
As a Party member, I’ll take the lead in everything.
She works as a nurse.
Tom has me as one of his best friends.
注意2：as 和like 都可以作介词,但意义不同.as 表示以实际的身份或地位.
like 则表示与……相似,以与……相类似的方式.例如：
He spoke as a teacher.
He spoke like a teacher.
这句的意思是：他作为老师发言或他以老师的身份发言.句的意思是：他讲话很像是老师.
五、用于一些固定搭配
1. as good as 差不多,几乎
Don’t worry, the matters as good as settled. 别担心,问题差不多已经解决了.
When the car was repaired, it looked as good as new. 这辆汽车修理好的时候,看起来差不多就像新的一样.
2. as if /as though 似乎；好像
He behed as if nothing had happened. 他装着若无其事的样子.
She treats him as though he was her own son. 她待他好像待自己的儿子一样.
另外,as if 可以接一个动词不定式短语.例如：
He wed his hand to me as if to he something to tell me. 他向我挥手好像有什么要告诉我.
3. as well as 同；和；还Joan can speak Chinese as well as English. 琼能讲英语还能讲汉语.
He spent all his money, as well as wasting his time. 他不仅浪费了时间,还花光了他所有的钱.
4. such…as, such as 像……这样的
I bought a lot of fruits, such as apples, oranges, bananas and so on. 我买了许多种水果,像苹果,桔子,香蕉等.
We had such books as you never saw. 我们有一些你从未看过的书.
5. as for 至于某人
We had a delightful weekend in the country. As for the traffic, we hadno difficulty. 在乡下我们度过了一个愉快的周末.至于交通,我们没遇到任何困难.
6. as to 关于某事物；提到某事物
I don’t know anything as to the others. 至于其他,我一无所知.
7. so as to…以便, 为了
Students should take notes so as to make revision easier. 学生应当记笔记,以便容易复习.
8. as a matter of fact 其实；实际上
As a matter of fact, I’m very fond of housework. 其实,我很喜欢做家务.
9. as a result 结果
As a result, he had been given an excellent job. 结果,他得到了一份极好的工作.
10. as long as 只要
You may borrow this book as long as you promise to give it back. 只要你答应归还,你就可以把这书借走.
总之,通过以上的分析,我们对as 的词性和用法有了比较全面的理解和把握,才能在实际的运用中做到心中有数,应付自如.
