高一英语Unit4语法“V-ing”的用法教案
Ｉ．Teaching Goals教学目标
本课的中心是“v-ing”。旨在通过单元教学，让学生学会使用v-ing的用法，熟练的掌握、运用v-ing形式做定语和状语。
Goals 1.V-ing 形式 do + ing 构成 否定：not do + ing 2.V-ing的用法
II．Teaching important points教学重点、难点
1. 重点：V-ing 形式在句中作定语和状语是本课的学习重点
2. 难点：同学往往会混淆v-ing的两种形式即现在分词形式和动名词形式 III. Teaching procedures & ways 教学过程与方式 Step 1 Warming up 1. 师生问好
2. 开始新话题：老师今天进门的时候看了一眼班级，用英语应该怎么表达？ 3. 学生讨论，最后师生一起得出结论：The teacher entered classroom looking around the whole classroom.引出本课要点v-ing。 Step 2 New knowledge
1. 指出v-ing用法的重要性以及普遍性 2. 具体教学
形 式 完成式 (not) having done (not) having been done 语态时态 主动语态 一般式 (not) doing 被动语态 (not) being done 用 法 V-ing 形式在句中作定语和状语 1. 作定语 V-ing 形式可以单独充当名词的前置修饰语, 这时有两种情况。 1) -ing形式表示 “供作......之用”的意思, 这类作定语的-ing形式叫动名词。 A swimming pool = a pool for swimming 2) -ing形式表示 “......的” 意思, 叫现在分词 A sleeping child working people the rising sun -ing形式短语作定语时一般放在它所修饰的名词之后, 相当于一个定语从句。如: They are visitors coming from several countries. The boy standing there is a classmate of mine. 2. 作状语 可以表示时间, 原因, 结果,条件, 行为方式或伴随动作等。 1) Four people entered the room looking around in a curious way. = Four people enter the room and looked around in a curious way. ( 伴随动作) 2) Being poor, he couldn’t afford a TV set. 原因 3) Using your head, you’ll find a good way. 条件 4) He came running back to tell me the news. 方式 5) (When) Hearing the news, he got frightened.= When he heard the news, he got frightened. 时间（可以在分词前保留when） 6) The child slipped and fell, hitting his head against the door. 结果 PS: -ing分词所表示的动作常与谓语动词的动作同时发生 -ing形式作状语时, 它的逻辑主语必须与主句的主语是一致的。 如：Time permitting, I will pay a visit to the whole city. (分词的逻辑主语是time , 而句子的主语是I , 两者不构成主谓关系, 所以只能用独立主格结构, 也就是给现在分词补充一个主语。) Step 3 Practice
