You can keep the book for 5 days.I stayed there for 2 weeks last year.How long did you stay there last year?二. 非延续性动词也称终止性动词、瞬间动词,表示不能延续的动作,这种动作发生后立即结束。如:open, die, close, begin, finish, come, go, move, borrow, lend, buy等。非延续性动词在肯定句中与表示时间点的状语连用，如：two years ago; at 5 oclock;例:He died 5 years ago.否定的终止性动词可以与表示时间段的时间状语连用。例:I havent left here for 3 years. I havent heard from him for 3 weeks.三.延续性动词与非延续性动词之间的转换：leave - be away, borrow - keep, buy - have, begin/start - be on,die - be dead, finish - be over, join - be in+组织机构, be a member of+组织机构,open sth - keep sth open, fall ill - be ill, get up-be up, catch a cold - have a cold,come here - be here, go there - be there, become - be, come back - be back,fall asleep - be asleep, get to/ arrive/reach - be (in), leave - be away from,get to know - know, go (get) out be out， put on wear；catch a cold have a cold等。例:The old man died 4 years ago. -The old man has been dead for 4 years.- It is 4 years since the old man died. -Four years has passed since the old man died.He joined the Party 2 years ago. -He has been in the Party for 2 years.I bought the book 5 days ago. - I have had the book for 5 days.
