When he was eating his breakfast, he heard the doorbell ring.  When he had finished his homework, he took a short rest．（finished先发生）  When I got to the airport, the guests had left．（got to后发生） Come whenever you like. 注意：表示“每当…的时候”(暗示一种规律性)，一般要用 when： It’s cold when it snows. 下雪时天冷。

He smiles when you praise him. 你夸奖他时他总是笑笑 ‚when 可表示“这时(突然)”；I was just coming along to see you when I ran into Wilson. We were about to start when it began to rain. 我们正要出发，这时天开始下雨了 ƒ在将来时从句中，常用when，且从句须用一般时代替将来时主将从现原则 When the manager comes here for a visit next week，I’ll talk with him about this. (2)while引导的的动作必须是持续性的,不能和瞬间性动词连用 Please don't talk so loud while others are working . While Mary was writing a letter, the children were playing outside. I kept silent while he was writing. 注意：①while还可作并列连词，意为“然而，但是”，表示前后对照，说明两种情况相反。

Tom is very outgoing, while Jane is shy and quiet.Some people waste food while others haven’t enough. ②可引导让步状语从句，意为“虽然，尽管”（多放句首），从句和主句主语多为同一人或物 While I understand what you say, I can’t agree with you. (3) as引导一个时间状语从句，其动作为持续性动作，多用于主句和从句动作交替进行或同时发生，可翻译为“一边……，一边……”或者“随着时间的推移” She wept as she spoke.她边说边哭 He looked behind from time to time as he went.他一边走，一边不时地往后看 As the time went on, the weather got worse.(as表示“随着……”之意) The atmosphere gets thinner and thinner as the height increases.随着高度的增加，大气越来越稀薄。

(4)如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作，此时when，while 与as可互换使用 When /While /As we were dancing，a stranger came in.(dance为延续性动词)当我们跳舞时，一位陌生人走了进来 When /While /As she was making a phone call，I was writing a letter.(make为延续性动词)当她在打时，我正在写信练习】1.

牢记‘前’（before）接后，‘后’（after）接前这样的口诀 I started my meal before he arrived.After we had finished tea we all sat on the grass. 为表示两个动作紧接着发生，从句可用过去时代替过去完成时： After she finished her work, she hurried to the nursery to pick up her child.3、before 和since (1) before有时可译为“还没……就” He had measured me before I could say a word. 我还没来得及说话.他就给我最好了尺寸 I hadn't waited long before he came. 我还没等多久他就来了 I slipped out before the lecture started. 还没等讲座开始我就溜了出去 before也可用于it结构，与 since 结构比较相似，注意它们所用时态的区别 其结构是:It will be + 一段时间 + before sb. does sth. 表将来 常译作“还要多久才会……” 或 It was + 一段时间 + before sb. did sth. 表过去 常译作“过了多久才……”。
