【学情分析】
学生是四年级的学生，已经具备了一定的英语基础。

他们对于
be动词的变化和一般过去时的基本概念有了初步的了解，但可能还不够熟练。

他们对于描述人或物的现在和过去状态可能还存在一定的困惑。

在学习过程中，教师需要提供大量的口语练习和示范，帮助学生加深对语言形式和意义的理解。

同时，通过歌谣学唱的形式，激发学生的学习兴趣，增强记忆和学习英语的乐趣。

【教学过程】
Step 1: Warm-up
教师与学生互动，问候学生，引发学生对过去和现在的讨论。

教师可以问一些问题，如"What did you do yesterday?"或"What do you usually do after school?"，鼓励学生用英语回答。

例子：
Teacher: Good morning, everyone! How are you today? Let's talk about what we did yesterday. Jack, what did you do yesterday after school?
Jack: I played soccer with my friends in the park.
Teacher: That sounds fun! How about you, Sarah? What did you do yesterday?
Step 2: Presentation
教师出示图片，包括一些描述人或物的现在和过去状态的场景，例如：一个脏的房间和一个干净的房间。

教师引导学生观察图片，用英语描述现在和过去的状态。

教师板书wasn’t和weren't，并解释它们的用法和意义。

通过例句和示范，让学生理解这两个单词的否定
例子：
Teacher: Look at these pictures. Can you describe the room in each picture? How is the room now? How was it in the past?
Student 1: The room is clean now.
Student 2: The room wasn't clean before.
Teacher: Great job! "Wasn't" is the short form of "was not," and "weren't" is the short form of "were not." We use them to talk about the past when something was not true or didn't happen.
Step 3: Practice
学生进行口语练习，使用wasn’t和weren't描述图片中的场景，如"Alice's room wasn't clean yesterday, but today it is clean."。

教师可以提供一些句子开头，让学生继续完成描述。

学生分组进行对话练习，描述自己和组员的过去和现在状态，例如："You weren't tall when you were a baby, but now you are tall."。

例子：
Teacher: Now, let's practice using "wasn't" and "weren't" in sentences. Complete the sentences with the correct forms of the verbs.
1. The cat ___________ hungry, but now it is full.
2. We ___________ at home yesterday, but today we are at
3. You ___________ happy last night, but now you are sad.
4. The flowers ___________ beautiful before, but now they are withered.
Step 4: Listening and Reading
播放活动2的录音，让学生听懂文本大意。

然后，教师逐句播放录音，让学生跟读，并纠正他们的发音和语调。

学生分角色朗读对话，并进行小组表演，展示他们对文本内容的理解和表达能力。

例子：
Teacher: Now, let's listen to a conversation between Amy and Tom. Listen carefully and repeat after me.
Amy: What were you doing yesterday, Tom?
Tom: I wasn't feeling well, so I stayed at home.
Teacher: Great! Now, I want you to work in pairs and take turns reading the conversation. Pay attention to your pronunciation and intonation.
Step 5: Singing
教师引导学生学唱歌谣"A little chick"。

教师先唱一遍，然后学生跟着唱。

教师可以使用手势和肢体语言来帮助学生理解和记忆歌谣的内容。

学生分角色表演歌谣，展示他们的合作和表演能力。

例子：
Teacher: Now, let's learn a fun song called "A little
chick." Watch me first, and then you can sing along. (Teacher sings the song with actions) Now, it's your turn! Sing along and do the actions. Great job! Let's divide into groups and perform the song together.
Step 6: Consolidation
教师总结本节课的学习内容，重点强调wasn’t和weren't的用法以及描述现在和过去状态的句子结构。

教师提醒学生在日常生活中观察和描述人或物的变化，加强对所学内容的巩固。

例子：
Teacher: Today, we learned how to use "wasn't" and "weren't" to talk about the past when something was not true or didn't happen. We also practiced describing the present and past states of people and things. Remember to observe and describe the changes you see in your daily life. This will help you reinforce what we've learned today.
