二.现在完成时中for和since的用法
for与since都能与现在完成时连用，但区别较大：
for后须接“时间段”，since后须接“时间点”。
Eg: He has studied English for three years.
他学英语3年了。
Eg: He has studied English since 2003.
他从2003年开始学英语。
Language points
二.现在完成时中for和since的用法
since与for可以互换：for + 一段时间 = since + 一段时间 + ago
Eg: He has been here for 3 years.= He has been here since 3 years ago.
他在这儿已经3年了。
since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而for则不能。
Eg: He has taught here since he came to China.
自从他来到中国就在这儿教书。
Language points
二.现在完成时中for和since的用法
since与for引出的时间状语往往用 how long 提问
Eg: — How long have you had this book 这本书你买多久了？
— For a week./Since a week ago. 买一周了。
