Module 2 Public holidays Unit 3 Language in use 外研九年级（上） Learning Objectives 1. understand the usage of the adverbial clause of time; 2. use the adverbial clause of time correctly. By the end of the class, we will be able to: 时间状语从句 在英语中如果我们用从句来表示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。时间的状语从句一般由从属连词when, while, as, since, after, before, as soon as, till, until等引导。 1. When引导的时间状语从句 When的意思是“当......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. When I got home, I found my baby girl singing in the sitting room. 2. as soon as引导的时间状语从句 as soon as表示“一......就”，强调动作紧密相连。例如： And my family always go somewhere interesting as soon as the holiday begins. We began to work as soon as we got there. 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. Mother sometimes prepares dinner after I come back from school. 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. Don’t make any noise while I am recording. 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. I will wait until you finish all the work. *本模块第一单元对话中出现了包含until的句子，但until后接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 Shangdong Province and we’ll stay there until the end of the holiday. 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. He has studied very hard since he came to our school. Language practice 1. Complete the sentences with the correct form of the words or expression in the box.
