23、等，这些动词不能和表示一段时间的时间状语连用。 但是，非延续性动词的否定形式可以表示状态的延续，可与for/since等时间状语连用。 整理ppt 有些同学错误地认为这类非延续性动词不能用于完成时态中。其实，错误的本质在于非延续性动词与时间段的错误搭配，与现在完成时态无关。整理ppt延续性语境中的非延续性动词的使用延续性语境中的非延续性动词的使用 在具体的语言环境中，往往会出现非延续性动词与时间段相连用的情况。由于受汉语影响，往往错误地直译为：He has fallen asleep for an hour.他睡了一小时了。（）His father has died for three yea

24、rs.他父亲去世三年了。（）当出现这种情况时，我们往往采取以下解决方法：整理ppt（1）将非延续性动词转化为相应的状态动词。所谓状态动词就是指这一动作发生后接下来所呈现的状态。如： He has been asleep for an hour. （fall asleep,“入睡”为短暂动作，但be asleep“睡着”则为状态动词，可延续。） His father has been dead for three years.（die为短暂动词，“死”后的状态可用“be dead”这种系表结构来描述，可延续。）整理ppt常见的这种动词的转化有以下几类：常见的这种动词的转化有以下几类： go th
