Unit2 Digital life语法讲解与练习 while/as soon as时间状语从句精讲 核心知识点精讲 A. while 引导时间状语从句 含义：当……时候；在……期间；而（表对比） 核心用法（必考重难点）： 只接延续性动作：从句动词必须是延续性动词（work, surf, chat, use, watch 等），不可接瞬间动词（arrive, stop, finish, begin）； 主从句均为进行时:强调两个长动作同步并行,多用于描述同时进行的数码生活行为；可表对比：前后动作形成反差，译为“……而……”； B. as soon as 引导时间状语从句 含义：一……就……（强调动作立刻、紧接着发生） 1. I will reply to your message as soon as I log in to my account. （我一登录账号就回复你的消息。） 2. As soon as the teacher shared the online link, all students joined the class. （老师一分享线上链接，所有学生就进入了课堂。） 3. He turns off his computer as soon as he finishes his online study. （他一完成线上学习就关掉电脑。） C.易混辨析（while/as soon as核心区别） 1. while：长动作、同步进行、时间段，无先后顺序； 2. as soon as：短动作、先后顺序、即刻发生，有明确时间先后； 3. while 绝不接瞬间动词，as soon as 无动词限制。 专项练习题 大题一：单词正确形式填空 1.
