清風如你：as的多種詞性與用法辨析
The secret to happiness is this: Let your interest be as wide as possible, and let your reactions to the things and persons that interest you be as far as possible friendly rather than hostile.
——The Conquest of Happiness
幸福的祕訣是：儘量擴大你的興趣範圍，對感興趣的人和物儘可能友善。
——羅素《幸福之路》
一、你知道as有幾種含義嗎？
adv.
1.同樣地；和…一樣地
He runs as fast as Paul.
他跑得和保羅一樣快。
2.例如
These poems were written by poets as by keats and shelly.
這些詩篇是詩人例如濟慈和雪萊寫的。
conj.
1.當…時；在…的同時
I was coming in as he was going out.
我進來的時候，他正出去。
2.因爲，由於
As this question is of great interest, we will discuss it once again.
因爲這個問題很有意義，所以我們決定再討論一次。
3.如同，像…一樣
Things were almost as they had been before.
事情還如同以前一樣。
4.儘管，雖然
Intelligent as you are, I suspect you will fail.
儘管你聰明，我還是猜想你會失敗。
5.隨着
The search intensified as dusk approached.
隨着黃昏將至，搜尋加強了。
prep.
1.如同
He does this job as a skilled labour.
他做起這個活如同個熟手。
2.當作，作爲，以…的身份
He worked as a cashier in a bank.
他在一家銀行幹過出納。
二、詞義辨析：類似具有“雖然”意思的詞有：
though, although, as
這些連詞均可表示“雖然，儘管”之意。
though和although在意義上幾乎毫無區別，但文體上後者是較正式用詞，語氣比though強。
此外，在習慣用法上這兩個詞仍有以下一些差異：
gh可引出倒裝語序的讓步狀語從句，although 則不能。
gh可與even連用，although則不能；在as though結構中，只用though，不能用although。
gh可以置於從句末，而although則不能。
4.引出省略句時，通常用though。as引出讓步狀語從句只用於倒裝語序結構中，語氣強於上述兩個連詞。
三、含有as的常見短語：
as a matter of fact
ad. 事實上，其實
as far as possible
儘可能…
as follows
adv.如下
as it is
事實上,實際上,既然如此,像現在這樣
as usual
像平常一樣,照常,照例
四、“as”的意思掌握了嗎？檢測一下吧
Another policeman has been injured fighting continued this morning
今早又有一名警員在衝突中受傷。
