用於指距離,表示“直到……為止”之意時,as far as既可用於肯定句,也可用於否定句,但so far as只能用於否定句中.例如:We went as far as Lion Rock Tunnel.我們一直走到獅子山隧道公路那兒.They did not go as far as the others.他們沒有像其他的人走得那麼遠.(此句的as far as可以改作so far as)(二)在表示“直到……程度”之意的借喻說法中,as far as和so far as都可使用,但前者不及後者用得普遍.例:she went so far as (or as far as) to call him a coward.她甚至罵他是儒夫.(三)在表示“就……而論”之意時,as far as和so far as可互換使用.例:As (or So) far as I koow,she will be away from Macao for two months.據我所知,她將要離開澳門兩個月.As (or So) far as my knowledge goes,there is no such word in English.據我所知,英語裡沒有這樣一個字.(四)在表示“只要”、“盡……所能”之意時,應用as far as,不用so far as.例:I"ll do my utmost to help you as far as I can.只要可能,我一定竭盡全力來幫你.Eric Partridge在他編著的Usage and Abusage一書中寫道(第44頁),在用作比喻意義的敘述句裡,so far as比as far as用得普遍,他舉了這樣一個例子:so far as I can see,your idea is admirable.
