After making sure the students have understand all the rules, I will ask them to find the sentence pattern “Ifyoullthe teachers willwe will”by themselves.)T:现在，我们再来仔细看一下，老师用红色的笔标注的地方，都有什么规律呢。“Ifyoullthe teachers willwe will” OK. Very good. 这些句子翻译成中文就是“如果你就会老师就会我们就会”我们在上一节课说过，这种句子结构在英语中被称为条件状语从句。If you wear jeans，”“如果你穿牛仔裤。”这只是一个前提条件。后面的“we wont let you in.”“我们不会让你进去。”是在这个前提条件下发生的事情。前面我们学习过原因状语从句和时间状语从句,在原因状语从句中和时间状语从句中。一个句子在句中充当了原因和时间的成分。在这儿，“If you wear jeans，”这个句子充当了条件状语，所以它被称为条件状语从句。在我们运用条件状语从句的时候，有三个特别需要注意的地方(注意哦，好记性不如烂笔头，这儿要开始记笔记了)：1、在条件状语从句中，如果主句是一般将来时态或具有将来的含义，从句的谓语动词常用一般现在时态表示将来。We won=we will not Ill=I will Youll =you willIf he comes, let me know.If you become an actor, youll be very famous.2、条件状语从句可以放在主句之前也可以放在主句之后。比如说：If you study hard, youll get a high score.=Youll get a high score if you study hard.3、条件状语从句除了可以用if引导之外，还可以用unless引导。Unless的意思是“如果不、除非”You cant go to the party unless you have an ID card.=You cant go to the party if you dont have an ID card.Unless=If not Step3: Practice & Consolidation (10minutes)T:现在把书打开。Turn to page 36. (Ask students to finish the close-filling task in 3a and check the answers.)Karen: Are you going to_?Mike: Yes, I am _ to wear my new jeans.Karen: You cant do that.Mike: What will happen if I do?Karen: _ You should wear your cool pants.Mike: Thats a great idea.(Ask two students to read the dialogue in 3b. Then let students practice with their partners following the example.) Few minutes later, Ill ask two or three groups of students to play their dialogues in front of the class. Step4: Review & Homework Design （5minutes）T: 同学们，再回头看看我们今天都学习了什么啊？对，条件状语从句。那么条件状语从句又有哪些需要注意的地方呢？1、在条件状语从句中，如果主句是一般将来时态或具有将来的含义，从句的谓语动词常用一般现在时态表示将来。2、条件状语从句可以放在主句之前也可以放在主句之后。3、条件状语从句除了可以用if引导之外，还可以用unless引导。Unless的意思是“如果不、除非”T: 好了，今天的课就上到这儿了。今天的作业就是与本小组的同学讨论练习并且完成4 Pair work. OK！Class is over. See you.VII Blackboard DesignMain Part:1、在条件状语从句中，如果主句是一般将来时态或具有将来的含义，从句的谓语动词常用一般现在时态表示将来。2、条件状语从句可以放在主句之前也可以放在主句之后。3、条件状语从句除了可以用if引导之外，还可以
