Step 1：Warm-up & Revision & Lead-in①

1. Greetings.

2. Let’s chant.

    3. Free talk.

T: How was your weekend?

Ss: It was interesting/great/boring/bad/…

T: What did you do last weekend?

Ss: I…

4. Lead-in.

Can you guess what I did last weekend?

Ss: Did you…?

T: No, I didn’t. / Yes, I did. I read a book last weekend. It’s Alice in Wonderland. I liked it very much. It was great.

Give students several chances to guess the answer. Then present a picture of “read a book”. Lead students to learn the new word “read” and pay attention to its form and pronunciation. In the simple present tense and the past tense, it looks the same, but pronounces in different ways.

◆ Teaching purpose①

歌谣热身能活跃课堂气氛，营造轻松的学习氛围。快速简短的自由对话和猜答案游戏帮助增进师生间的交流，创造和谐的师生氛围，帮助复习本单元前三课时所学的重点短语和句型，为后面的学习打好基础。

Step 2：Presentation

1. Learn the time.②

(1) Present the calendar. (出示课件)

Last weekend was the 18th and 19th day of this month. (Circle and point the time.)

T: What about the 25th and 26th day? (Circle and point the time.)

Ss: It’s this weekend.

T: Today is Friday. It’s the 24th day. (Point to the date and circle it.)

T: What about the 23rd day?

Ss: It was yesterday.

T: And the 22nd day was…?

T: Excellent! You all did a very good job. Now look at the time we present here. Can you find out some regulations? When do we use “this” “before” and “last”?

Ss: …

(2) After students share their opinions, the teacher makes a brief summary. Then extend “last week” “last Monday” with the help of the calendar.

(3) Present the key words and phrases of the past time on the PPT. (出示课件) Students read the words after the teacher and learn the ways of expressing the past time. The teacher can extend “tomorrow” and “the day after tomorrow” after students have a good command of the past time.

(4) Pair work. (出示课件)

Students ask and answer the questions.

S1: What did he/she do…?

S2: He/She…

◆ Teaching purpose②

利用日历的直观数轴式呈现，有效帮助学生理解表示过去时间的状语。通过对时间不同层次的推进，让学生先观察再尝试总结过去时间状语的使用方法，提升学生的自主学习和思维能力。利用简短的对话设计，结合场景图片，快速复习旧知，整合新知。

2. Learn the phrase “saw a film”. ③

T: Do you know the book Alice in Wonderland? It’s a very famous book. And it’s also adapted into a film. The film is fantastic.

Play a short part of the film. (课件出示：电影《爱丽丝漫游仙境》片段)

Ss: Yes, I did. / No, I didn’t.

T: When did you see the film?

Ss: I saw it…

Teach the words “see—saw” and the phrase “saw a film”. Students read after the recording, and pay attention to its irregular word-formation.

◆ Teaching purpose③

延续热身活动引出的《爱丽丝漫游仙境》绘本，借此引出由此改编的电影，通过影片剪辑的短视频，带领学生初步领略经典文学著作，同时多感官的呈现方式有助于加深学生对生词的理解。

Ss: Because when she read the book and saw the film, she looked happy.

(2) Present the two pictures of John.④

T: How did John feel?

Ss: He felt sad/bad/sick/tired… (Present the words “feel—felt”.)

T: Why did John feel so bad?

Ss: Because he had a cold. (Present the phrase “had a cold”.)

T: No wonder he slept. Maybe sleeping could help him feel better. (Present the words “sleep—slept”.)

Teach the new words and the phrase. Lead students to read after the recording, and pay attention to their irregular word-formation.

◆ Teaching purpose④

情境导入学习had a cold和slept，通过观察图片中人物的表情和状态，推测其心理状态。在提高学生语言表达能力的同时，培养学生的观察能力。通过动词原形和动词过去式的对比，引导学生关注和了解常见动词过去式的不规则形式。

Step 3: Practice
