?since和for的区别
since和for都用于现在完成时中，其中since后面可接过去的时间点，也可接“一段时间＋ago”，还可以接从句；for后面只能接“一段时间”。如：
My parents have lived in this city since 2009.我的父母从2009年起就居住在这座城市。
She has been a doctor since two years ago.她从两年前就当医生了。
Lily has had the toy bear for two years.莉莉已经有这个玩具熊两年了。
【注意】(1)终止性动词也称非延续性动词，可以用于现在完成时，说明某个动作的结果还存在，但不能与表示一段时间的状语连用。如：
The Whites have come back.(正)
The Whites have come back for two days.(误)
(2)在否定句中，终止性动词可以与表示一段时间的状语连用。如：
I haven't heard from my friend for three weeks.我已经有三周没有收到我朋友的来信了。
【拓展】当终止性动词与表示一段时间的状语相矛盾时，常用以下方法进行转换：
(1)用ago把现在完成时的句子改为一般过去时。如：
He has left the village for six days.(误)
He left the village six days ago.(正)
(2)用“一段时间＋has passed＋since＋一般过去时”句型改写。如：
She has borrowed the book for two weeks.(误)
Two weeks has passed since she borrowed the book.(正)
(3)用“It has been＋一段时间＋since＋一般过去时”句型改写。如：
His grandfather has died for a few years.(误)
It has been a few years since his grandfather died.(正)
(4)用系表结构(be＋形容词副词)改写或用相应的延续性动词代替终止性动词。如：
come/arrive/go→be in/at, begin/start→be on，finish/end/stop→be over，open→be open, die→be dead，leave→be away，close→be closed，fall asleep→be asleep，join→be a member of/be in，become→be，buy→have，borrow→keep，get to know→know，put on→wear，catch a cold→have a cold，come back→be back
