B. just, already, yet, befre/ ever, never有此类副词时,常强调动作完成,不强调动作的持续.
短暂性(短语)动词与延续性(短语)动词和与表示状态的短语之间的转化1. 有些短暂性(短语)动词可转化为相应的延续性(短语)动词。常见的有： becme → be （成为） brrw → keep （保管） buy → have / wn （购买） catch a cld → have a cld （感冒） cme → stay （来，停留） put n → wear（穿着） g t sleep → sleep （睡觉） mve t → live in（搬到）
2. 有些短暂性(短语)动词可转化为表示状态的短语。常见的有： leave → be away （离开） begin / start → be n（开始） die → be dead （死亡） finish → be ver（结束） jin → be in / be a member f（加入） fall asleep → be asleep （睡觉） marry → be married （结婚） cme / arrive here → be here（来到，到达这儿）
巧记瞬间性动词的转换： 开始离去借来还， 出生入死买到家，穿衣入睡要感冒， 开开关关变结束。
