Homework:让学生去调查身边的人或事物,写一写____ is faster /slower than ____. 教学反思:

本节课是一节典型的关于比较级的语法课.小学阶段的语法教学应体现隐性语法教学原则,作为教师不应为学生直接讲解语言中出现的语法概念,而是应通过创设的语言情境,让学生在活动中去感悟,理解出现的语法现象,从而掌握所学的语法知识.本节课,通过创设真实的语言情景,为学生呈现公共汽车,飞机和火车的图片,教学比较级句型____ is faster than ____. _____ is slower than _____. 所以教师又充分利用了儿童节即将到来这一真实情景,为学生提供了学习英语和用英语交流的语言环境.通过本课的学习,学生较好地掌握了所学单词和句型,并能积极主动地加以运用,达到了预期的教学目标.

Lesson 21: How Can We Go to Beijing? 一、教学目标： 知识目标：

1、掌握单词airplane、train

2、掌握两组比较级fast、faster、slow、slower 能力目标：

能够在句子中正确运用fast、faster、slow、slower 情感目标：

培养学生用英语表达思想的能力和习惯 二、教学重难点

1、四会单词：airplane / plane, train, fast, slow, faster, slower。 2、两组比较级在句子中的正确运用 三、教学具准备

多媒体课件、 实物模型、词汇卡、录音机、调查表 四、教学过程

（一）Class Opening and Review 1、Greeting.

2、Let’s chant : how do you go to school? How do you go to school? By bus, by bus. How do you go to school? By bike ,by bike. How do you go to school? By car, by car. How do you go to school? On foot, on foot.

(设计意图：利用全身反应法，唱唱做做，提高学生学习兴趣，营造欢快的课堂气氛，并且为新授的交通工具做好铺垫。) （二）教授Part1

1、教授单词airplane、train

利用chant 中的How do you go to school ？对学生提问，由此复习交通工具，在复习时所用的词汇卡中放入新卡片airplane、train并教授。教授train时注意tr字母组合的发音并拓展。教授airplane时注意它的另一种说法plane.

（设计意图：复习与新授同时进行，使学生轻松自然地接受新知识。） 2、欣赏优美的北京名胜图片

（设计意图：再次吸引学生的注意力，但更重要的是引出How can we go to Beijing?进而引出fast、faster、slow、slower） 3、教授fast、faster、slow、slower

T：Beijing is so great! Do you want to go on a trip to Beijing with me ? S： Yes !

T：But how can we go to Beijing ? S: 答出各种去北京的方式。

T：There are many ways to Beijing, but I think the airplane is fast and the bus is slow. （对比教授fast 、slow 并做动作）

T：Look at the bus and the train， which one is slower ? S：The bus

T：Yes, the bus is slower than a train .

T：Look at the airplane and the train， which one is faster ?

The plane is fast.The airplane is faster than a train. but it cost too much ? I want to take a train.

Because the train is cheaper. (肢体语言对比展示fast、faster、slow、slower 后学生读大屏幕上的句子。 )

(设计意图：通过肢体语言的运用和两种交通工具的对比，既达到了对本课中的隐性语法—“比较级”的习得目的，又加深了对本课单词的记忆，另外还渗透了本课的歌曲。) 5、听Part1的录音

听音前出示任务1 ：a. 模仿正确的语音语调跟读课文后小组内互相读。 b. 同桌间用____is faster than ____.

____is slowerer than ____. 造句。比一比看谁造句多而且正确。 (设计意图：学生进一步熟悉课文后进一步拓展，使学生灵活运用本课的两个比较级句型。) 6. Play a game: Guessing

通过教师或学生的描述猜出是那种交通工具。 如：It is faster than a train..What is it ? (设计意图：通过游戏,使学生对本课重点句型的意义和用法体验的更深，掌握的更牢固。) （三）教授教授Part2

1、出示任务2：Listen to the tape and answer question . a. What does LiMing want to by? b. What does his mother want to by? c. What do they want to take at last? 播放录音，学生听后回答问题。

(设计意图：让学生带着任务听录音，边思考边听，效果更佳。) 2、再次播放录音，放音前出示任务3
