参考答案：延续性动词表示能够延续的动作.如：study, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等.
延续性动词可以与表示时间段的状语连用.
表示时间段的短语有:for+ 时间,for 2 years; since从句,since he came here; since+时间点名词,since last year, since 5 days ago; how long; for a long time等.
例:He has lived here for 6 years. You can keep the book for 5 days.
I stayed there for 2 weeks last year. How long did you stay there last year?
请采纳,谢谢!
再问： 额.....不知道是我表达不清楚还是怎么，我也不怎么懂 例如 death → have die
再答： die为非延续性动词，而不是延续性动词，
判断一个动词是否是延续还是非延续性动词，你可以用”动词+一段时间“，看看是否符合逻辑，
符合逻辑者为延续性动词，不符合逻辑为非延续性动词。
请采纳，谢谢支持！
