Question

如题所述

Answer 1

一、so long as 和as long as, 都有“……不如……一样长”的意思，有时可以互换。但用法有点不同。
1、so long as 只能用于否定句中，意思是“……不如……一样长”。
2、as long as 用于否定句与“so long as ”同义； 用于肯定句，意思是：“……和……一样长”。另外，它还有“只要”的意思，引导状语从句。
如：
1). The stick isn't as long as that one.
= The stick isn't so long as that one.
这条棍子不如那条长。
2). The stick is as long as that one. (此句不能用 so long as )
这条棍子和那条一样长。
3). I will help you as long as I have time . (此句不能用 so long as )
只要我有空我就会帮助你。
二、so far as 和as far as 都有“……不如……一样远”的意思，有时它们可以互换，但用法有点不同。
1、 so far as 只能用于否定句,意思是“……不如……一样远”。
2、as far as 可用于否定句，此时与“so far as” 同义。也可用于肯定句，意思是“ ……和……一样远”。
3、作为“就……而言”“从……来看”“尽……所能”“只要” 解时，两者可互换。
如：
1).We walked as far as the river. (此句不能用so far as )
我们一直走到河边。
2).We didn’t go as far as the others.
=We didn’t go so far as the others.
我们走得不如其他人远。
3).As far as I know, that is highly unlikely.
= So far as I know, that is highly unlikely.
就我所知，那是极不可能的。
