问题描述：
does it take him to get to school?--About fifteen minutesAHow often B.How longCHow far
答
how long
首先来看
how often表频率,指几次比如once a week,这个选项一看就是错的,排除
how long 表时间长短,符合题意
how far 这个会有人混淆,为何是选how long而不是how far呢?
要是选how far,后半句就该改成 about fifteen minutes'walk 大约十五分钟的路程,而且一般还要加方式,我写的这句是指走路,那么还可以是by bike,by bus 等等
综上,选B
不懂就问呐
