Chapter 6 Memory教案

Chapter 6 Memory 一. 教学内容： Chapter 6 Memory Language and writing （一）“if”与“unless”引导的条件状语从句和状语从句知识归纳 （二）课后书面表达讲解 二. 知识总结与归纳： “if”与“unless”引导的条件状语从句 条件句，放在前，逗号要放句中间。 条件句表可能，主句多用将来时 条件句表事实，主句常用现在时。 在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。如： We can walk there if we can’t find a bus. If it rains tomorrow, we will not go to the zoo. What will you do if you find a panda in danger 如果 if 条件句谈论的是重复发生和预示 要发生的情景和事件，则主从句大多用一般现在时态。如：If bears are in danger，they attack people. 要点：表示状语从句由连词if，unless（＝if not） 引导。 1. If it doesn’t rain tomorrow, we will go hiking. 如果明天不下雨，我们就去远足。 2. You will get good grades if you study hard. 如果你努力学习，就会取得好成绩。 3. I will go to the party unless he goes there too. 我不会去参加聚会的，除非他也去。（如果他不去，我也不去。） 4. You will be late unless you leave immediately. 如果你不马上走，你将会迟到的。（＝If you don’t leave immediately, you will be late.） 难点提示：用条件状语从句时要注意时态的正确使用，当主句是将来时的时候，从句要用一般现在时。 1. He will not leave if it isn’t fine tomorrow. （一般将来时，一般现在时 2. They are going to have a picnic if it doesn’t rain next week （一般将来时，一般现在时） [状语从句知识归纳] 状语从句（Adverbial Clause） 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词（从属连词）引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。 状语从句的种类 用来修饰谓语动词、其它动词、定语、状语或整个句子的从句叫做状语从句。状语从句可分为： 1. 时间状语从句；（adverbial clause of time） 2. 地点状语从句；（adverbial clause of place） 3. 原因状语从句；（adverbial clause of cause） 4. 条件状语从句；（adverbial clause of condition） 5. 目的状语从句；（adverbial clause of purpose） 6. 让步状语从句；（adverbial clause of concession 7. 比较状语从句；（adverbial clause of comparison） 8. 方式状语从句；（adverbial clause of manner） 1. 时间状语从句（adverbial clause of time） 由when，while，as引导的时间状语从句。例如： When you think you know nothing, then you begin to know something.
