As是英语中用得比较多的一个词,也是很多学生反映较难掌握的一个词。as的词性较多,用法也较复杂,因此掌握该词会对英语学习很有帮助。下面对as的用法作一个归纳。
一、As用作连词
1)as表示“随着”之意,引导时间状语从句,而with也有 “随着”这一层意义,缺是介词,不能引导句子。
As time went on, he grew cleverer and cleverer.
=With time going on, he grew cleverer and cleverer.
随着时间的推移,他越来越聪明。
2)As表示“当……的时候”之意(=when). 引导时间状语从句,从句中的谓语动词可以是延续性动词也可以是非延续性动词,但while引导从句时,动词必须是延续性动词。
As/when/while he was away, Mr. Wang took the charge. 他不在时,王先生负责。
I saw him as he was getting off the bus.
= I saw him when he was getting off the bus.
但不能说,I saw him while he was getting off the bus.
他当下公共汽车时,我看见了她
3)As表示原因时,意思是“因为”,“既然”引导的从句可以放在主句之前也可以放在主句之后;而because 表示原因时,只能放在主句之后,重点在于说明原因或理由;since表示原因时,意思是,“既然”只能放在主句之前;for表示原因时,只能放在主句之后,表示对推理或判断的补充说明。
As he wasn’t ready in time, we went without him
因为他没有及时准备好,我们没等他就走了
4)引导方式状语从句意思是“如”,“像”
Please do it as I do it照我的样子做这件事
Leave it as it is 请保持原状不要动它,
5)as引导让步状语从句,意思是“虽然”,
“但是”位于句首采用倒装语序,把从句的表语和状语提前,或把动词提前。既把
从句中的形容词,副词动词或名词提到as前。常见的结构有以下几种:
A: ad j/ adv + as+主语+其提它结构 Young as he is , he knows a lot. 虽然很年轻,但他却知道很多。
Much as I like the necklace, I will not buy it .尽管我喜欢这条项链,我还是不会买的。
B: verb+ as+主语+情态动词/助动词+其他动词。 Try as she might, she couldn’t open the door.虽然她试了几次,但仍然打不开那扇门。
C: n+ as+主语+其他成分。
Child as he is, he has already known a lot.
尽管他是个孩子,但懂的很多。 值得注意的是从句中的名词是倒装词,名词前不用冠词
二、As用作关系词
1) As 引导非限制性定语从句,修饰整个句子,位置较灵活,可位于主句之前,也可位于主句之中或之后;而which引导非限制性定语从句,修饰整个句子只能位于主句之后。
The earth is round, as is known to all,
=As is known to all, the earth is round.
=The earth, as is known to all, is round
众所周知,地球是圆的。
Bamboo is hollow inside, which makes it light to carry 竹子是中空的,这使它拿起来很轻。
2)As可以用作关系代词或关系副词引导限制性定语从句,并在从句中作定语。表语或状语,构成the same…as, such…as等结构。
I like the same book as you do. (as作宾语)
I shall do it in the same way as you did. (as作状语)
I want to have such a dictionary as he has. (as作宾语)
The same…as…和the same…that… 二者的区别在于:the same…that…表示二者的“同一性”,而the same…as…有两层含义,即可表示二者的“同一性”,又可表示二者的“相似性”
She is wearing the same dress that she wore yesterday
她穿着昨天穿的那件衣服(同一件)
She is wearing the same dress as she wore yesterday
這一句有两层意义
她穿着昨天穿的那件衣服(同一件)
她穿的衣服像她昨天穿的那件,(非同一件)
三、As用作介词
1)“作为”,“当作”。
He was respected as a judge. 大家尊崇她是一名好法官
As a league member, I should take the lead in everything.
作为一名共青团员,我应该事事领先。
2)“当某人是……时”。(=while/when sb. is…)。
As a boy, he lived in Beijing.
=When/While he was a boy , he lived in Beijing.
四、As用作副词
在“as…as”结构中第一个as是副词,在非正式文体中可以省略,在美国英语中尤其如此。第二个as可以是介词也可以是連词,跟人称代词作宾语时可用其主格形式也可用其宾格形式。
基本用法如下:
1)如果我们要说两者在某一方面是一样的,用as + adj / adv + as;两者在某一方面A不及B时用not as/so + adj / adv + as。
She is as busy as a bee every day.
她每天都太忙了。
He drove as fast as he could. 他尽可能快开。
2)如果涉及数量,可以用as much…as…或as many… as…加一名词。
I haven’t got as much money as you thought.
We need as many records as possible.
As much,和as many 可作代词,后面不跟名词。
He got so hungry that he ate as much as he could at the table.
他很饿,在餐桌上吃了很多。
3)在as…as所比较的形容词接名词时,形容词应放在名词前,若有冠词。则应把冠词放在形容词和名词之间。所比较的两个名词必须是类别一致。
He is as good a student as his brother 他是一个同他弟弟一样好的学生。
He is as hard-working a boy as anyone else in his class.
他跟班上的任何一个同学一样是个勤奋的学生。
总之,应用语言的学习方法,熟记规律,合理运用,日积月累,循序渐进,就能在英语学习中熟能生巧,融会贯通,学生的学习成绩必能明显提高。
