问题探究
▲by的用法
他骑自行车去学校。He goes to school by bike.
by＋交通工具表示出行方式时，by后直接跟交通工具名词。类似短语：on foot步行。
▲take的用法
每天做作业花费他两个小时。
It takes him two hours to do his homework every day.
It takes sb. some time to do sth.做某事花费某人多少时间
▲辨析how long与how far
how long意为“多长时间”，用以询问某个动作所持续的时间；how far意为“多远”，用来询问距离或路程的远近。
(1)—____ does it take you to do your homework
—Two hours.
A. How long B. How
C. How far D. How much
答案选A。how long对一段时间进行提问。
(2)—____ is it from here to your home
—It's two kilometers.
A. How long B. How
C. How far D. How much
答案选C。how far用来询问距离，答语要用表示距离的词语。It指代的是距离。
