Step 1 Greeting & Revision

T：Hello, boys and girls. Are you ready for class? Good! Let’s begin our class. Today we’ll review “Unit 6 Keep our city clean”.

T: Cities are the places we live in, and we need to keep our city clean. In your eyes, is our city clean?

T:OK. I think some places in our city are clean and beautiful. But some places are dirty and messy. Let’s watch a video. What problems can you find out?

1. T: What problems can you find out?（贴problems） You please.

S1: The street is messy and dirty.

T: Yes. And what makes the street messy and dirty? （贴Reasons）

S1: Rubbish makes the street messy and dirty. (板贴…make(s)…)

T: What rubbish can you see on the street?

S2: I can see some bottles on the street.

T: What can we do to keep the street clean? （贴Ideas）

S3: We can put the masks and bottles in the bin.

2. T: What other problems can you find out?

  S1: The air is dirty.

T: What makes the air dirty?

S2: Smoke from cars makes the air dirty.

S2: I can take the bus to school.

T: Good boy. What else makes the air dirty?

S3: Black smoke from factories makes the air dirty.

T: Right. There are many factories. What can we do to keep the air clean?

S3: We can move some factories away from ou city.

T: Really? Move to the countryside? Then the air of the countryside will be dirty?

  I think it can’t solve the problem. Maybe we should develop and use new energy. (板贴new energy)

It helps reduce air pollution. For example, new energy vehicles are around us now.

3. T: Any more problems?

S1: The river is dirty.

T: What makes the river dirty?

S1: Dirty water makes the river dirty.

T: What can we do to keep the river clean?

S1: We can’t pour dirty water into the river. (板贴We can’t…)

T: That’s right. If there are some fish in the river. What will happen?

S1: They will be dead.

T: Yes. And the dead fish make the river dirty too. If we drink the dirty water in this river, what will happen?

S: We will be ill.

T: Right. And maybe we will have cancer. And probably we will be dead too. Is that terrible?

T: Look, these things make the city dirty and messy. We call them pollution. And what is pollution? Can you read?

S: Pollution is anything that makes the earth (地球) unhealthy and dirty.

T: So the first one is land pollution. (板贴land pollution)

  The second one is air pollution. (板贴air pollution)

 The third one is water pollution. (板贴water pollution)

看图片，T: Plastic bags(板贴Plastic bags) make the ocean dirty. And they also make the animals ill.

T: Do you have any good ideas to stop white pollution?

S1: I think we can use the paper bag. (板贴paper bag)

T: Great idea. In our daily life, we can’t use too many plastic bags. We can use paper bags and degradable plastic bags. When we have drinks, we can use paper straws.

T: Now I want you to think about whether I do something to keep our city clean in our daily life. Look at the city, what can I do to keep our city clean ?
