so far as和so far，as far as和as far区别及以上和so long as,as long as 所有的区别

Question

另外的题目：mr.smith is a quite honest man____ i konw
在as far，so far， so far as，as long as选一个 答案是so far as 为什么？它不是否定句才可以用的吗？

Answer 1

四个选项只能选so far as，表示“据我所知”的意思。as long as 是只要的意思，如果选项出现as far as 也对，但so far as and as far as 一般不会同时出现的

Answer 2

as far as I know = so far as I know 据我所知

as/ so far as 据…, 就…
As far as I know, he will be away for three months.
据我所知, 他将离开三个月。

但是为什么我的题答案是so far as呢？这个词组不是只能在否定句用吗
