1、1课题: Module 4 Unit 2 If a snake bites you, take a photo.序号：8知识与技能目标：重点语法：if 引导的条件状语从句if 引导的条件状语从句的两个语言点（1）if 的两个含义弄明白：是否/如果典型例句分析：I dont know if he will come tomorrow, if he comes, I will call you.（2）主从句的世态：主句用一般将来时，从句用一般现在时。典型例句分析：We will go to the park if it doesnt rain tomorrow.重点句型：Wherever you
2、are, you can go to an Internet caf. 无论你在哪里，你都可以去一间网吧。Wherever= no matter where 引导状语从句，类似的还有 however, whenever, whatever, whoever however=no matter howwhenever=no matter when Whenever you come, we will go to the airport to meet you.whatever=no matter what Whatever you do, Ill support you.whoever=no m
3、atter who重、难点：if 引 导的条件状 语从句一条件状语从句表示主句动作发生的条件，在初中阶段常由 if(如果)引导，表示假如有从句的动作发生就会有主句的动作发生。例如： Please call me if he is at home. 假如他在家的话 ，请给我打电话。 条件状语从句和主句还有一个共同的伙伴，有时它可以替代从句和主句，它就是“祈使句+and / or+简单句 ”。其中 and 表示句意顺承；or 则表示转折，意为“否则”。例如： If you work harder, youll pass the exam. = Work harder, and youll pass
4、 the exam.如果你再努力些，你就会通过考试。 If you dont hurry up, youll miss the train. = Hurry up, or youll miss the train. 如果你不快点儿，你就赶不上火车了。二比较下面两个句子:1.Tom wants to know if he needs to come early tomorrow.2.

6、主句和从句所表达的动作基本同时发生或表示客观事实时，主句和从句都可以用一般现在时。例如： When they walk, Cody walks. 3. 当主句的谓语动词是 want, wish,hope 等时，从句通常用一般现在时。例如： Do you want to be a policeman when you grow up? 4. 当主句是一般将来时、一般现在时(包括祈使句和含有情态动词 can, may, must 等)，上述两种情况中状语从句必须用一般现在时。例如： What are you going to do after you leave school? Be carefu
