Unit5状语从句复习 2023-2024学年牛津上海版（试用本）八年级英语下册

2023学年牛津上海版英语八年级第二学期U5状语从句复习 一、常见的状语从句简介 在句中充当状语的从句叫作状语从句。下面我们来认识一下时间状语从句、条件状语从句和原因状语从句吧。 1． 时间状语从句 引导时间状语从句的连词有when, before, after, since, until, as soon as等。如： I feel very happy when you come to see me. 你（们）来看我时，我感到很高兴。 We cleaned the classroom before we left school yesterday. 昨天离开学校之前，我们打扫了教室。 He called me after he had finished his work. 他在完成工作之后给我打了个电话。 We have made many dumplings since we began to cook. 自从开始做饭，我们已经包了许多饺子了。 2． 条件状语从句 常用if或unless来引导条件状语从句。如： If it doesn’t rain tomorrow，we will go there by bike. 如果明天不下雨，我们就骑自行车去那里。 You will be late unless you start early. 你会迟到的，除非你早出发。 3． 原因状语从句 常用的引导原因状语从句的连词有: because，as和since。如： He was angry not because we were late but because we made a noise. 他生气不是因为我们来迟了，而是因为我们弄出了声音。 As it was raining hard，we had to stay indoors. 由于雨下得太大，我们只好呆在家里。 Since you feel ill，you’d better not go to work. 既然你感觉不舒服，你最好不要去上班了。 注意：主句与从句时态一致的问题。 当主句是祈使句，或主句中有情态动词，或主句中谓语动词是一般将来时时，那么从句用一般现在时表示一般将来时。如： Be careful when you cross the road. 过马路时要小心。 Put up one of your hands if you have any questions. 如果你们有问题的话，请举手。 The traffic must stop when the lights are red. 红灯亮时，车辆必须停下。 二、练习 I.
