现在完成时的时态怎么转换啊？
现在完成时延续性动词的转换如下：
arrive→be here begin(start)→be on。
die →be dead come back→be back。
leave →be away from ill(sick，asleep)→be ill(sick，asleep)
get up→be up go out →be out。
finish →be over put on →wear 或be on。
open →be open join →be in或 be a member of
close →be closed go to school→be a student。
延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
非延续性动词也称终止性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。如：open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow, buy等。
