As用法小結

一、as作連詞的用法

1. as...as的用法

as...as意為"和……一樣"，表示同級的比較。使用時要注意第一個as為副

詞，第二個as為連詞。其基本結構為：as+ adj./ adv. +as。例如：

(1)This film is as interesting as that one.這部電影和那部電影一樣有趣。

(2)Your pen writes as smoothly as mine.你的鋼筆書寫起來和我的一樣流

暢。

其否定式為not as/so +adj./ adv. +as。例如：

This dictionary is not as/so uful as you think.這本字典不如你想象的那樣

有用。

若有修飾成分，如twice, three times, half, a quarter等，則須置于第一個as

之前。例如：

Your bag is twice as expensive as mine.你的袋子比我的貴一倍。

幾個關于as...as的常見句型：

(as possible

Plea answer my question as soon as possible.請盡快回答我的問題。

(as usual/before

She looks as pretty as before.她看起來和以前一樣漂亮。

(3)as (引導條件狀語從句)

It took us as long as three years to carry out the plan.我們花了長達三年的時

間才完成這項計劃。

(4)as far as

He walked as far as the railway station yesterday evening.昨天傍晚，他一直

散步到火車站。

(5)as well as

She cooks as well as her mother does.她燒菜燒得跟她母親一樣好。

2. as用作連詞引導時間狀語從句

as與when，while都是引導時間狀語從句的從屬連詞，含義都是"當……

的時候"。但它們有區別：用when時，從句的動作可以與主句的動作同時發

生，也可以先于主句的動作發生；用while時，從句的動作為一過程，主句動

作與從句動作同時進行或在從句動作過程中發生；用as時，主句和從句的動

作同時發生，具有延續的含義。例如：

(1)It was snowing when he arrived at the construction site.他到達工地時，天

正在下雪。

(2)He was watching TV while his mother was cooking.他母親做飯時他在看

電視。

1

(3) You will grow wir as you grow older.你會隨著年齡的增長而越來越聰

明。

3. as用作連詞引導原因狀語從句

as，becau，since都可以表示因果關系，連接原因狀語從句，含義是"因

為，由于"，但它們有區別：becau表示的語氣最強；as一般放在句首，語氣

較弱，較口語化；since常常用在書面語中，表示多為對方已知的、或稍加分

析便可得知的原因，有時可譯作"既然"。例如：

(1) He will succeed becau he is in earnest.他一定會成功，因為他很認真。

(2) Since you are so sure of it he’ll believe you.既然你對此如此有把握，他會

相信你的。

(3) As rain has fallen, the air is cooler.因為下過雨，空氣比較清爽。

4. as作連詞引導讓步狀語從句

as與although (或though)，however (或no matter how)等都可以引導讓步

狀語從句，含義是"雖然，盡管"，但它們有區別：although語氣稍正式些，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

語氣較強，引導的讓步狀語從句用倒裝語序；however引導讓步狀語從句時，

它的后面可跟形容詞或副詞，也要用倒裝語序。例如：

(1) Although he is quite old, he still jogs every day.他雖然年紀相當大，仍然

每天慢跑。

(2) Strange as it may em, nobody was injured in the accident.這次意外雖然

顯得令人不可思議，卻沒有人受傷。

(3) However hard he may try, he will not attain his goal.無論他怎樣努力也達

不到目標。

二、as作關系代詞的用法

關系代詞as引導定語從句時，既可以單獨使用，也可以與其他詞連用，

其用法要比that和which更為復雜。

1. as引導定語從句與其他詞連用

①用于as結構中

This is the same book as I read last week.這本書和我上周讀的那本是一樣

的。

②用于as結構中

I don’t like such books as he recommends.我不喜歡他推薦的那些書。

③用于"so +adj. + a/an + n. (單數) + as "結構中

I am not so strong a man as I was.我已經沒有從前那么強壯了。

2. as單獨引導定語從句

as單獨引導定語從句時，先行詞可以是一個詞，也可以是一個句子或短

語。例如：

(1) She is late, as is often the ca.她遲到了，這是經常的事。(先行詞是整

個主句)

2

(2) To shut your eyes to facts, as many of you do, is foolish.對事實視而不見

--你們好多人都是如此的愚蠢。(先行詞是不定式短語)

三、as作介詞的用法

as作介詞，意思是"作為"，"以……身份"。例如：

He came to China as a tourist five years ago.他五年前以游客的身份來過中

國。

四、as作副詞的用法

to the same degree or amount; equally "相同地"，"同樣地"。例如：

They don’t have as many airplanes.他們沒有同樣多的飛機。
