例如：KeeP an eye On my little SiSter while I am away. 我不在时，请照看一下我的小妹妹。
While We Were WatChing TV, Jim Came in. 我们看电视的时候，Jim 进来了。

As he was eating his breakfast, he heard the doorbell ring. (强调同一时间）As I was going out, it began to rain.(强调两个动作先后发生）As spring warms the good earth, all flowers begin to bloom. (as 有“随着”的含义）2) before “在……之前”，after “在……之后”强调事件的先后关系before表示两件事的先后关系。

但until可用于句首，till不能用于句首。
①till/until意为“直到”，用于主句为肯定句的表持续的谓语动词，如live，last, stand, stay, wait, work等时，表示主句的动作延续到从句所表达的动作发生为止，意为“一直到…………时”。

说明：若主句为肯定句的非持续动词，只用before,表示时间上“先于”。
He applied three times before he was finally admitted to the university.He made a mistake, but he corrected the situation before it got worse.②till/until用于主句为否定句的表非持续的谓语动词，如begin，become, get up, reach, start等时，until表达的一般是“主句动作的起点”意为“直到……才”，“在……之前（不）”。
He did not get up till his mother came in.直到母亲进来时他才起床。

He didn’t arrive before I returned.在我回来之前他尚未到达。
③It was not until…that…是“not until”的强调形式，不用倒装。
It was not until he saw his mother that he realized how old she had become.直到看见母亲，他才意识到母亲已经变老了。
It was not until I had read your letter that I understood the true state of affairs. 直到读了你的信，我才明白事实的真相。
since意为“自从……以来”，用于表示时间，要注意以下几点：① since从句后常用一般过去时，通常为非持续性动词，表示主句(现在完成时或现在完成进行时)动作的起始点：Electricity has been widely used since it was discovered.I have been looking forward to meeting you ever since Martin told me.②当主句用it表示“自从……以来已经有多少时间”时，谓语动词常用一般现在时,有时也可用将来时。
