我在字典上看见了how far is it from here to there?,here 和there是副词,那么为什么前面可以加介词 简单的英语知识请问有没有 by far 或者 by now 哪一个是直到现在,到目前为止.我记得好像都是,但是在字典上没查到,字典上的by far 也是另外一个意思.纠结了. How far is how far How far away is Silbury这里可以不要away吗?感觉far 跟away的意思在这里冲突了? 请问 as far as I am concerned 是个什么语法结构啊,我查了字典,as far as 为副词 for all i know 和as far as i know 区别刚在字典上看到这两个词组的意思都可解释为：据我所知；到底有什么区别? How far is it always是不是语法错了? How far is Mike?是哪里错了? _______is Mr Zhang's daughter?I don't know,but I'm sure she is too young to go to用how的短语写给了几个词，how manyhow much how long how soonhow often how far how long; how far; how often; how soon ;when;用在句子上怎么分清楚啊?例;--how often are you late for school?--Never,I don't feel like being late for school.希望帮我解释一下上面短语各个在句子上的用法!
