问题二1) lay off:解雇,停止工作,休息,划出
2)lay off sb:不在做打扰人,讨人厌的等的事 此时lay 为不及物动词 不允许将sb放中间
例：住手!你把我的头发都弄乱了!
Lay off!You're messing up my hair!
3) lay off sth:不在做或使用有害的事物等
例：我抽烟很多年了,现在打算戒了!
I've smoked cigrettes for years,but now I'm going to lay off them.
4)lay sb off:解雇工人（短期） lay为及物动词 当宾语不是代词是sb可置于中间可放后边,是代词时放中间,off是副词.
例：由于没有新的定货,他们遭暂时的解雇.
They were laid off because of the lack of new orders
