  I will tell him everything when he comes back.

  He won’t believe it until he sees it with his own eyes.

  (3)在带有till或until引导的时间状语从句的主从复合句里,如果主句用肯定式,其含义是“一直到……时”,谓语动词只能用延续性动词。如果主句用否定式,其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如:

  I’ll help you with your English if am free tomorrow.

  He won’t be late unless he is ill.

  (3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如:
