How far和How long的区别？

Question

列几个句子～
如果一句中有away,那该用哪个？怎么用？

Answer 1

how long （常用与完成时态）表时间的长短常与for +时间段连用 或与since +时间点

how long have you been skating ?
for two hours.
how long have you been skating ?
since 11:00

how far表距离的远近 常与away from连用
how far is it from your home to school?
my home is 3 miles away from school

by the way:how soon 也表示时间的长短但回答时为in+时间段
how soon is the dinner ready?（晚饭多久好）
in 5 minutes(5分钟后）

how far is it away from your house to the bank?
my house is 2 miles away from the bank.

how far is it from your home to school?
my home is 3 miles away from school

Answer 2

How long是“多久”的意思How long不是指距离，是指时间。How far才是指距离。例如：How far is your house?（你的家有多远？）而How long does it take to get to your house?是问‘到你家需时多久？’

How far away是”多远”的意思．本回答被网友采纳

Answer 3

how far是只指距离，away只是个副词，起修饰作用。
how far (away) is your college?
你的大学有好远？
how long是指时间，对时间提问。
how long do you spend getting there?

Answer 4

how far是距离上的远
how long是时间上的长短
