be, have, know, live, work, study, learn, teach, wait, wear, walk, sleep等，这些动词可以和表示一段时间的状语连用。
非延续性动词:
come, go, arrive, leave, begin, start, buy, join, die, borrow等， 这些动词可用于现在完成时，说明某个动作的结果还存在，但不能与表示一段时间的状语连用。
通常延续性动词可以表示一种状态，和表示一段时间的状语连用。
He has been here for two hours.
而非延续性动词通常表示某一动作的发生，要想用非延续性动词和表示一段时间的状语连用，必须要用相对应的延续性动词进行转换。
