连词主要有:when as while before after until as soon as since等
(1)区别when, as, while的用法
①.when“当......时候”引导的时间状语从句,其动词既可以是延续性动作的动词,也可
以是瞬间性动作的动词,如:
_________ the students heard the teacher's footsteps, they all stopped talking.当学生们听到老师的脚步声时,他们都停止了讲话。(从句动作发生在前)② as“当.......时候”或“一边.......一边”引导的时间状语从句其动词的动作是延续性的,而且侧重表示主句和从句的动作并相发生:
We were having breakfast __________ she was combing her hair.她梳头时我们在吃早饭。
③ while表示“在某一段时间里”或“在……期间”,其所引导的从句的动作是延续性的,并侧重表示和主句的动作同时发生。如:
I can learn ________ I work.我可以边工作边学习。
用when, as, while填空:
________ you came in, I was talking with a few boys.It started to rain __________ we were playing outdoors.They talked _________ they walked down the river.__________ it was raining, the students were playing basketball.Her brother watched TV__________ he ate supper.(4)before引导的时间状语从句,指时间上的“在……之前”

(5)as soon as表示“一……就”,做题要注意主将从现
As soon as we __________(get)there, he ___________(tell)us the news.我们一到那,他就会告诉我们那个消息。
(7)since引导的时间状语从句,从句的谓语动词通常为一般过去时,主句的谓语动词
通常为现在完成时
We __________ never __________(meet)since we ___________(graduate)from
the college.大学毕业后我们就再没见过面。
(8)till/until引导的时间状语从句 till和until同义,作“直到……时(为止)”解,till多用
于非正式文体,until多用于句首;not … until通常与after进行转换。如:
I won't go with you until(till)I finished my homework.=____________________________________________________________________.等我做完作业我才和你一起去。
