【设计意图】通过观看视频引出本模块关于人口的话题，激发学生的兴趣。

Step 2 Pre-listening

(1) Learn the new words and expressions by reading aloud together.

2. Work on Activity 1.

(1) Ask Ss to talk about the picture using the words in the box in groups.

(2) Invite some Ss to share their discussion.

【设计意图】词汇练习，旨在通过让学生了解听力中会出现的生词，为下面的听力和对话扫清语言上的障碍。

3. Work on Activity 2.

(1) Play the recording and ask Ss to choose the correct answer. 

(2) Ask Ss to read the large numbers in Activity 2.

Step 3 While-listening

Listen and do the tasks.

1. Choose the correct answer.

What are Tony and Lingling mainly talking about?

A. The problems of fast-growing populations. 

B. The world’s population.   

C. The population of India.

2. Answer the following questions.

(1) Which countries are seeing the most population growth?

(2) What problems will be caused when populations increase too fast?

(3) What are the problems of slow-growing populations?

3. Listen and complete the notes.

Step 4 Post-listening

1. Read the dialogue and act it out in groups.

2. Learn the language points.

(1) I’m preparing a report called “The world’s population”.

prepare v. 准备；预备

prepare … for … 表示“为……准备……”。

(2) It said the world’s population was about 7.8 billion in 2020.

population 意为“人口”，用large 或small来修饰。

(3) When populations increase too fast, it can cause problems, such as too much traffic and noise.

too much意为“太多”，其后接不可数名词。

辨析：noise, voice与sound

 (4) By 2030, India will have about 1.5 billion people.

billion 数词，意为“十亿”。在英语中，hundred, thousand, million和billion前面有具体数字时，它们都要用单数形式；但是当与of搭配使用时，它们都必须用复数形式，表示概数，而且不能与具体的数字连用。
