fall 是不是延续 性动词

fall 是不是延续 性动词
不是,fell 意为落下,降落 跟arrive/reach 到达 buy 买 close 关 　　post 邮寄 fall 落下 die 死 　　leave 离开 go 去 break 打破 　　lose 丢失 give 给 join 加入 　　receive 接收 borrow 借 move搬 　　hear 听到 同属短暂性动词 依据是发生的时间不长
如果与一段时间连用 必须把它们转化成延续性动词
如borrow→keep,buy→have,begin/start→be on,die→be dead,move to→live in,finish→be over,join→be in/be a member of,open sth.→keep sth.open,fall ill→be ill,get up→be up,catch a cold→have a cold become --- be,come back --- be back,fall asleep --- be asleep,get to/ arrive/reach --- be (in),leave --- be away from,get to know --- know,go (get) out →be out,put on→ wear等 相应地,fall可转化为be fell
