一边……”。‎ He hurried home，looking behind as he went.‎ 他匆忙回家去，一边走一边回头望。‎ As time went on，it's getting warmer and warmer.‎ 随着时间的推移，天越来越暖和了。‎ ‎2．till和until 在肯定句中主句谓语动词应是延续性的，而在否定句中主句谓语动词应是非延续性的；till不可位于句首，而until则可以。‎ You may stay here till/until the rain stops.‎ 你可以待在这里直到雨停。‎ I won't see him till/until his anger has cooled down.‎ 等他怒气消了，我再去看他。‎ Until you

‎，主句用完成时。since引导的从句如果用非延续性动词，常理解为某一状态的终止；若用延续性动词或状态动词，则理解为某一动作的开始。since引导时间状语从句的常用句型：It is/has been＋时间段＋since...“自从……以来多久了”。‎ He has written to me frequently since I got sick.‎ 自从我病了以后，他经常给我写信。‎ It is three years since he came to our school.‎ 他来我们学校已经三年了。‎ It is three years since he smoked.‎ 他戒烟已经三年了。‎ ‎4．引导时间状语从句的名词词组 一些表示时间的名词词组，如the moment，every time，each time，the first time，the last time，the next time，the minute，the instant等可以用来引导时间状语从句，起连词的作用。‎ The moment I saw her，I knew there was something wrong.‎ 我一看到她，我就知道出事了。‎ Every time I was in trouble，he would come to help me.‎ 每次我处于困境，他就会来帮助我。‎ ‎5．表示“一……就……”的引导词 as soon as，immediately，directly，instantly，the moment/minute/instant，no sooner...than...，hardly/scarcely...when...等都可引导时间状语从句，表示“一……就……”。‎ The boy burst into tears immediately he saw
