how long, how soon, how often, how far 区别
① How long 多久，多长(时间)。对时间段提问，如: for+ 时间段；since+过去的时间点/过去时的句子。必须与持续性动词连用。
-How long have you worked in Beijing?
-For five years. / Since five years ago.
② How soon 多久以后。对“in+时间段”提问，常用于一般将来时，其答语常用“in+时间段”。
e.g. --How soon will Mr. Li be back?
--In a week.
③ How often 多久一次，对频率提问，其答语为: once (twice/…)+时间段, always, usually 等。
e.g. --How often do you exercise?
--Once a day.
④ How far 多远，对距离提问，其答语是表距离的内容。
e.g. --How far is it from here to your school?
--Three kilometers.
2. be in+地点
意思是待在某地，表持续的状态。可以与一段时间连用。如果地点是here, there, home, abroad等副词时，要省去in。
注意：短暂性动词(come, go, leave …)可以用于现在完成时。但不能用于有for或是since的肯定句中。
-How long have you been in No.41 Middle School.
-I have been here for almost two years.
-你来41中多长时间了？
-我来41中差不多两年了。
