用 until 连接的从句表示前面的动作到了这个时间点随即结束.如果前面是瞬间动词表示的没有执行的动作,到了until 这个特定时间就变成执行状态；如果前面是延续性动词表示的执行着的动作,到了until 这个特定时间就变成不再执行状态.如要说“一直到她母亲回来她才不再看电视”,就可以用瞬间动词和延续性动词两种手段表示：
　　She (didn’t stop) watching TV until her mother came back.（stop 是瞬间动词,意思是她没有执行stop watching TV的瞬间行为,这种情况一直发展到母亲回来才告结束）
　　She (watched) TV until her mother came back.（watch 是延续性动词,意思是都在执行着watchedTV行为,这种延续情况一直发展到母亲回来才告结束）.
until 标示的是一个时间点,在短暂的时间点上不可能存在进行状态的动作,因此 until 引导的时间状语只能与一般过去时和过去完成时（包括完成进行时）或者一般将来时和将来完成时连用.如：
　　She (had watched) the TV program until her mother came back.（在她母亲回来以前,她曾看过这个电视节目）
　　She (had been watching) TV until her mother came back.（直到她母亲回来,她都在看电视来着）
　　She (will watch) TV until her mother comes back.（一直到她母亲回来,她才不再看电视）
　　She (willhave watched) the TV program until her mother comes back.（在她母亲回来以前,她将看完这个电视节目）
如果要表示“她正看着电视,这时候母亲突然回来了”,应该说 She (was watching) TV (when) her mother came back.

She watched TV until her mother came back.这句话为什么前面不用过去进行时? I watched TV until she came back.(不是not until么?) Not until she came back not did I watch TV.这句话的语序对了吗 She ( doesn't）go to bed until her mother came back .括号里的形式对吗 “梅梅直到妈妈回来才看电视”Meimei ___ ___ TV ____ her mother came back she often watched tv this evening 这句话语法对吗? back daughter until to didn not came her bed go she Her friend_____here until she came back.选择A:will leave B:won Her mother came back while she ( )her homework A did B doing She doesn't go to bed until her mother comes back翻译, She won’ t go to bed until her mother ----- back tonight she went to bed after her mother came back (该同义句)
