现在完成时的瞬间动词有哪些？

瞬间动词就是非延续动词，表示动作一产生就结束了，常用的瞬间动词有open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy,die,etc
现在完成时中如果用瞬间动词，一般其后不跟表示时间段的时间状语。
我们可以说the dog has died.但我们不可以说the dog has died for several days.此时需要把非延续性动词die变成延续性动词be dead。据此句子转变成the dog has dead for several days.是可以的。
常用的这种需转换的还有
leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。
延续性动词用于现在完成时，其完成时态可与表示"段时间"的状语连用。表示"段时间"的短语有：for two years, during the past three years, since last year, how long等。

像keep就是有延续性的
borrow 就是非延续性的
