李新艳

一、教材分析(Teaching materials) 《Lesson21 Look at the Photos》是冀教版三年级起点第四单元第三课，本单元的主题是Did you have a nice tipe?主要内容是：李明、Danny、Jenny回家后回顾旅途情景的话题，学习过去时态。本课主要为学生提供了李明、Danny和Jenny各自回家后与亲人讲述旅途见闻及感受的场景，帮助学生初步学习一般过去时的表达方法。

二、教学目标(Teaching aims) 1.学生能听懂、会说、认读并书写下列词汇：photo, were, was, happy 2.通过本节课的学习，使学生继续加深对现在时和过去时概念的理解。

3.通过独立阅读发现新知，在不同时态的语句对比中发现规律，形成自主学习能力。

三、教学重难点(Teaching points and difficulties) Be 动词过去分词的应用。

四、教学准备(Teaching preparation) 教师准备：教学课件，课文录音，人物头饰，生活照片，学习卡

五、教学过程

Step 1: Warm-up 1.课前三分钟，学生带大家一起复习过去分词。

2.向学生问好：Hello students! Yesterday Iwent to a park．What did you do? 【设计意图】通过师生对话引导孩子复习过去分词。

3．课文情景剧导入

T: Last week, we shared the story of Jenny. Today we share the story of Danny. T: We previewed the text,part 1.Now I

have

some

photos

to

show

you! Ask

the students to perform a sitcom.who wants to try? 4. 让学生看60页第1部分。浏览课文，挑选出所有过去时态的动词，并找学生领读过去分词，让学生区分规则变换和不规则变换的过去分词。

5.大屏幕上写下这些句子，让学生进行填空并读句子

We were on the train to Beijing. We played with the baby. It was fun. Danny was at the Palace Museum．

What happened? He hurt his tail. 【设计意图】通过情景剧表演，创设了情境，使学生在情境中感知过去时态。

Step 2: Presentation 1． Is and was (1) 在黑板上写下am, is, are，并小组内找不同点。

(2) 向学生解释，am, is和are是现在时态的动词。讲解何时以及如何使用这些词。现在时态：

I am happy. He is happy. She is happy. You are happy. We are happy. They are happy. 这些句子相应的过去时态：

I was happy. He was happy. She was happy. You were happy. We were happy. They were happy. 记住：

对于I/she/he，在过去时态中用was，在现在时态中用am/is。

对于you/they，在过去时态中用were，在现在时态中用are。

【设计意图】通过对比找出Be动词不同时态用法的不同规律。

(3)播放录音，让学生跟读。

【设计意图】通过跟读录音训练学生朗读表达能力。

2．

学生拓展性训练

让学生分小组练习be动词的过去分词习题。

Step 3: Practice 三分钟小创作

Step4: Homework 1．介绍自己家人的照片，并记录在作业本上。

2.向父母讲一讲Danny、Jenny、Liming的故事 3．预习Lesson22。
