中文词源

as 如同

由古英语alswa 分化出来的两个单词as 和 also, 后在词义和语法上逐渐产生了变化。

英语词源

as
as: [12] Ultimately, as is the same word as also. Old English alswā ‘in just this way’ was used in some contexts in which modern English would use as, and as it was weakly stressed in such contexts it gradually dwindled to als or ase and finally to as.
=> also
as (adv.)
c. 1200, worn-down form of Old English alswa "quite so" (see also), fully established by c. 1400. Equivalent to so; any distinction in use is purely idiomatic. Related to German als "as, than," from Middle High German also. Phrase as well "just as much" is recorded from late 15c.; the phrase also can imply "as well as not," "as well as anything else." Interjection of incredulity as if! (i.e. "as if that really could happen") is attested from 1995, an exact duplication of Latin quasi.

词语辨析

【as, because, for, since】
这些连词均含有“因为”之意。
as: 从属连词,语意较because, since弱,着重在主句,所表示的原因或理由是“附带的”。
because: 从属连词,语意强,着重直接的原因或理由,所引出的从句是全句的重心,用以回答why提出的问题。
for: 并列连词,语气较弱,所引出的句子一般放在后面,表示附带说明的理由或推断理由。
since: 语意比because弱,但比as强,一般用于表示“由于大家已知的事实”。

【as, like】
这两个词均有“像”之意。
as: 从属连词,引出方式从句。
like: 是前置词,后面跟的是宾语。

【when, as, while】
when: 从句动词点动词,持续性动词均可,
as: 重在表示动作同时发生,伴随进行,
while: 从句动词为持续性动词 While I slept, a thief broke in.

【though, although, as】
这些连词均可表示“虽然,尽管”之意。
though: 和although在意义上几乎毫无区别,但文体上后者是较正式用词,语气比though强。此外,在习惯用法上这两个词仍有以下一些差异:1.though可引出倒装语序的让步状语从句,although 则不能。2.though可与even连用,although则不能;在as though结构中,只用though,不能用although。3.though可以置于从句末,而although则不能。4.引出省略句时,通常用though。
as: 引出让步状语从句只用于倒装语序结构中,语气强于上述两个连词。
