延续性动词及短暂性动词在现在完成时中的应用
①延续性动词与短暂性动词在现在完成时中的使用: （1）延续性动词：be，have，knw，live， wrk，study，learn，teach，speak，talk，draw， wait，wear，walk，sleep等，这些动词可以和表示一段时间的状语连用。例如： Uncle Wang has wrked in this factry fr ten years． 王伯伯在这家工厂工作十年了。 （2）非延续性动词：cme，g，arrive， reach，see，hear，clse，leave，begin，start，lse， buy，fall，jin，die等，这些动词可用于完成时态，说明某个动作的结果还存在，但不能和表示一段时间的状语连用。例如： 【正】The play has begun . 戏开演了。（戏正在演着） 【误】The play has begun fr half an hur． 戏开演半小时了。 【正】 The play has been n fr half an hur.
