As, but和then這三個字都是很特別的字,因為as, but和then通常用作連接詞,但有時也能作關係代名詞用,稱之為準關係代名詞。如:
I helped him, as was my duty.(我幫助他,因那是我的責任)(此句的as可以用which來代替)
There is no rule but has exceptions.(沒有沒有例外的規則)(此句的but has=that has no exceptions)
Don't give him more money than is necessary.(不要給他超過所需要的錢)
談完這三個特別的字,再回來談談as
文法學家Micheal Swan曾經講過:as和than可以引導沒有主語或賓語代詞(有點像as和than是關係代詞)的從句。沒有主語代詞的從句主要用在正式文體中。
如:Their marriage was as stormy as had been expected.(他們的婚姻正如所預科的那樣幾經波折)(不能說:...as it had been expected)(沒有主語)
Anne's going to join us, as was agreed last week.(正如上週大家同意了的,安妮將加入到我們中間來)(不能說:...as it was agreed last week)(沒有主語)
Don't lose your passport, as I did last year(別像我去年一樣把你的護照丟了)(不能說:...as I did it last year)(沒有賓語)
看了這樣的解釋後,以後當見到as, but, then所帶的子句沒有主語或賓語時,相信你也不再奇怪!
至於be my Valentine(通常用大寫)的be,意思是:成為,用廣東話就是”做”,如:be my friend就是”做我的朋友”,書寫語是”成為我的朋友”,所以be my Valetine就是”做我的情人”或”成為我的情人”
