楼上的解释的很好
我再补充一点
how
soon
通常是对in+一段时间的提问
如
He
will
be
back
in
five
minutes.
如果把in
five
minutes
划上,就它来提问,就应该是楼上的那句:How
soon
will
he
be
back?
How
long通常是就时间长短来提问的,如:It
takes
me
two
hours
to
get
to
school.
如果把two
hours
划上,就它来提问,就应该是:How
long
does
it
take
you
to
get
to
school?
另外补充一个how
far,它是就距离来提问的,如:The
school
is
two
kilometers
away
from
my
home.
按要求变为特殊疑问句就应该是:How
far
is
it
from
the
school
to
your
home?
以上
希望有所帮助
