as far as 和 so far as 的区别


一 用于指距离,表示“直到……为止”之意时,as far as 既可用于肯定句,也可用于否定句,但 so far as 只能用于否定句中。

二 在表示“直到……程度”之意的借喻说法中,as far as 和 so far as 都可使用,但前者不及后者用得普遍。例:she went so far as (or as far as) to call him a coward. 她甚至骂他是儒夫。

三 在表示“就……而论”之意时,as far as 和 so far as 可互换使用。例: As (or So) far as I know,she will be away from Macao for two months.
据我所知,她将要离开澳门两个月。
As (or So) far as my knowledge goes,there is no such word in English.
据我所知,英语里没有这样一个字。

四 在表示“只要”、“尽……所能”之意时,应用 as far as,不用 so far as。例: I’ll do my utmost to help you as far as I can.
