Module2 Public holidays 语法讲练：时间状语从句的用法及练习（含答案）外研版英语九年级上册

Module 2语法讲练：状语从句（1）：时间状语从句的用法 如果我们用从句来表达一件事情或一个行为发生的时间，那么这个从句就叫时间状语从句。不同的引导词引导的时间状语从句的意思也不同。下面我们来看一下本模块中出现的几种常见的时间状语从句： 1. when 引导的时间状语从句 when 的意思是“当……的时候”，既可以表示在某一时间点发生的事，又可以表示在某一时间段发生的事。主句与从句描述的动作或事情可以同时发生，也可以先后发生。例如： When the weather is fine, many people go out for a walk. 天气好时，很多人都出去散步。 When I got home, I found my baby girl singing in the sitting room. 我到家时，发现我的小女儿正在客厅里唱歌。 2. as soon as 引导的时间状语从句 as soon as 表示“……就……”，强调动作紧密相连。例如： And my family always go somewhere interesting as soon as the holiday begins. 假期一开始，我们全家就会去某个好玩的地方。 We began to work as soon as we got there. 我们一到那儿就开始工作了。 3. before/after 引导的时间状语从句 before 表示“在……之前”，after 表示“在……之后”。例如： Before we begin dinner, my father gives thanks for the food. 吃饭前，我父亲会表达（因拥有食物而产生的）感激之情。 Mother sometimes prepares dinner after I come back from school. 妈妈有时在我放学回家后才准备晚饭。 4. while 引导的时间状语从句 while 引导的时间状语从句表示主句的行为在从句行为进行的过程中发生。由于 while 从句表示一个持续的行为，所以从句中要用持续性动词或状态动词，且持续性动词常用进行时态。例如： While they were crossing the Atlantic, many people died. 他们中的很多人在横渡大西洋时丧生了。 Don’t make any noise while I am recording. 我在录音时（你们）别发出声音。 5. until 引导的时间状语从句 until 表示动作或状态一直持续到某一时刻，即“直到……”。例如： He waited until all the guests left. 他一直等到所有客人都走了。 I will wait until you finish all the work. 我会等到你完成所有工作。 本模块第一单元对话中出现了包含 until 的句子，但 until 后续的不是时间状语从句，而只是时间状语： My parents and I are going to visit some friends in Shandong Province and we’ll stay there until the end of the holiday. 我和父母要去山东拜访一些朋友，我们会在那儿一直待到假期结束。 此句中 until 之后接的短语 the end of the holiday 等同于时间状语从句 until the holiday is over。 6. since 引导的时间状语从句 since 引导的时间状语从句常与完成时连用，表示“自从……”。例如： I have known Bill since he was born. 从比尔出生起，我就认识他。 He has studied very hard since he came to our school. 自从来到我们学校，他学习就非常努力。 Module 2 时间状语从句习题 一、连词选择题：选择正确的时间状语从句连词完成句子 1. _____ I was reading, my brother was playing games.
