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， like，等。
终止性动词也称非延续性动词、瞬间动词或短暂性动词，表示不能延续的动作，指动作在很短时间内完成，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， die, join, become, return,等。1. What ________ your brother ________ (do) at nine o’clock last night?
