1、 语法
2、 动词按持续时间分类:瞬间动作、延续动词
瞬间动词:start、finish、buy、borrow、lend、die、come、go、arrive、leave(*瞬间动作不能跟时间段)
延续动词:read、watch、learn、work、stand、know、walk、wait、live、stay(*延续性动作可以跟时间段)
3、 瞬间动作转化为延续性动作
瞬间动作——————延续性动作
buy——have borrow——keep start/begin——be on
die——be dead return——be back finish——be over
leave——be away marry——be married close——be closed
(be+副词/介词短语/形容词,表状态,是可持续性的)
