学习策略：
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，课堂以学生为主，教师引导为辅。
教学重点：
感知be动词的过去形式，并学会灵活使用。
教学难点：
正确使用一般过去时，并有意识地运用过去时态描述照片。
教学过程：
Step 1: Greetings and Review:
Hello, boys and girls! Yesterday I went to the shop. I shopped some fruit. What did you do yesterday? I did my homework. /I had breakfast….
Have—had eat—ate do—did go—went see—saw walk—walled etc
(设计意图：教师日常性场景问候，利用学过的动词检查所学，巩固复习过去时。)
Step 2: Presentation
Lead in: Danny and Jenny are talking about photos of Beijing. Can you guess what happened to Danny? Now let’s look at Danny’s story.
Part I:
1. Questions:
a. Where was Danny? (Picture 1)
b. What happened to Danny? (Picture 2)
c. Was Danny at the Great Wall? Did they feel happy? (Picture 3)
(设计意图：以故事为线索，让学生带问题发现所需答案，并踊跃参与到师生对话中来。)
2. Find past form of the verbs from Part I
was ,were, happened, played, hurt
教师在学生找出这些动词过去式(past form)后，引导学生说出这些词的动词原型(original form)。
(设计意图：检查学生熟练的识别动词过去式变化的规律，并通过教师引导，给出动词的原型，并初步感知was ,were的动词原型。)
3. 朗读Part I (听录音读，男女生角色朗读、单个角色朗读2-3组)
（设计意图：熟读课文，感受动词过去时在文章中的使用。）
Part II:
1.以文中的一般现在时的句子为例，以对比的方式呈现过去式的句子。（幻灯片展示）
He is eight years old this year. He _____ seven years old last year.
I am happy today! I ___ sad yesterday.
We are in Canada this week. We_____in China last week.
