(1)用“How's the weather in Sydney?”和“Bad. It's raining.”询问某地的天气状况并做出应答;用“Ice/…can become water/….”说出冰、雪、雨、水的变化。 (2)能认读词汇hot, become, clever, ice,并能在实际情景中运用。 2.教学难点:
(1)用“How's the weather in Sydney”和“Bad. It's raining.”询问某地的天气状况并做出应答;用“Ice/…can become water/….”说出冰、雪、雨、水的变化。 (2)hot发音/?/的口型位置。
三、教具准备
单词卡片、头饰(教材人物),冰、雪、雨、水图片、水杯、热水、冰块、给学生的评价奖品(stickers:冰、雪、雨、水图片等)、教学课件等。
四、教学过程
(一)Listen and say
分析与提示
·本单元的主题是大自然的一些现象及变化。本部分内容旨在通过对话,学习要求掌握的交际用语及单词,了解一些科普知识。
·建议结合三年级学过的有关天气、季节的内容。进一步充实、深化教学内容。 1.导入
(1)师生从谈论天气和季节的对话形式导入。 T: What's the weather like today? Ss: It's….
T: What season is it now? Ss: It's winter.
T: Yes, it's winter. And is it cold or hot in winter in Beijing? Ss: It's cold.
T: What do we have in winter, snow or rain? Ss: Snow.
T: It snows in winter in Beijing. In what season does it often rain in Beijing? Ss: In summer. T: That's right. 2.学习对话1 (1)观察对话情景。
·PPT中出示第一幅图场景(或将图贴在黑板上)。 T: Please look at the picture. What do you see in it? Ss: Maomao, Lala, snow, snowflakes….
·教师引导学生猜测Maomao和Lala的对话内容。 T: “What does Lala say, can you guess?” Ss: ….
(2)初听理解对话。
T: Let's listen! What does Lala say? (Play the dialogue, “It doesn't snow in summer.”) Ss: It doesn't snow in summer. (Students repent) T: No. It doesn't snow in summer. Do you know why? Ss: Because….
T: Please listen. (Play the dialogue. “Because it's hot and snow becomes rain.”)
·用图片或一杯热水学习hot一词,注意其发音/?/。Become turn into可在PPT上用图片解释,snow图片变成rain图片。 T: Please listen and repeat.
Ss: Because it's hot and snow becomes rain. (Students repeat)
T: It doesn't snow in summer. Because it's hot and snow becomes rain. It snows in winter. Do you know why?
Ss: Because it's cold and rain becomes snow in winter. T: Clever! Ice can become water and water can become ice. ·教师用手势教学clever,用实物或图片教学ice。
此时教师板书冰、雪、雨、水之间的变化关系,并进行语言操练: In hot summer, snow can become rain. In cold winter, rain can become snow. In warm weather, ice can become water. In cold weather, water can become ice. (3)听录音模仿跟读。
·播放对话录音,学生模仿跟读。 ·学生集体朗读对话。 ·学生自读对话,内化理解。 (4)角色扮演。
·学生分角色朗读对话。
·1～2组学生表演对话。教师做出评价。
