Learning Objectives
PART. 01
Understand the daily study and life of British middle school students by watching videos. Based on your own daily study and life, compare the study and life in Chinese and British schools, and find out the similarities and differences between the two. Talk about your first impression of high school life, and have a preliminary perception of the study and life in the senior high school stage.
Learning Objectives
Extract opinions and arguments about plastic packaging from dialogues, identifying “for/against” stances and solutions. Improve understanding of spoken English on environmental debates. Through group work and role-plays, discuss plastic-related issues, practice making/accepting suggestions.
Explore cultural values of reducing plastic waste, understanding global concerns about environmental protection. Recognize how different cultures address plastic-related issues, fostering a sense of shared responsibility.
Analyze dialogues to distinguish “for/against” arguments, and solutions. Break down complex issues into components, evaluating their feasibility. In group work, innovate by proposing unique solutions to plastic waste, applying creative problem-solving to real-world environmental challenges.
Use “opinion-identification” strategies and “suggestion-making” structures. By independently completing listening tasks, reflecting on plastic - related choices, and practicing suggestions, students take ownership of learning.

In the week when the government sets out its new environmental programme, Kevin McCabe and Alicia Stewart consider the problem of food packaging waste.
K: On my way home from work yesterday, I stopped off at a local supermarket. Among other things, I wanted to buy a couple of coconuts. When I picked them up, I was amazed that each coconut was wrapped in clear, thin plastic. Isn’t this the most stupid example of packaging ever
A: You’ve picked an unusual example of packaging, but there is a reason for this. Supermarkets want to make sure that coconuts reach the consumer in the best condition. The packaging helps to keep the product fresh; it means the product will last longer.
K: I understand that, but in this case it’s completely wasteful and unnecessary. I mean, why wrap a coconut in plastic It already has its own natural packaging. It’s got a tough shell that’s almost impossible to break!
Role-play Kevin and Alicia.
A: Yes, but the plastic wrapping also has other uses. For example, it stops coconut hairs from getting into other food during transport. And it keeps the coconut clean during the transportation process.
K: Is anyone really worried about a bit of dirt on a coconut And what about the environment A lot of the plastic used in packaging never recycles. It’s terrible for the environment: Our oceans are full of plastic waste, and animals and birds end up swallowing the plastic and dying as a result.
A: I have to say I agree with you on that. Some food packaging cannot be recycled, and that’s not good enough — the packaging should be changed so that it’s recyclable. But let’s be realistic: We still need packaging. We just need to use the right kind of packaging.
K: I think we need a more innovative solution. I really believe we should do away with packaging completely. There’s a supermarket in Germany that has no product packaging at all. Its customers take refillable containers with them when they shop, and use them instead of plastic boxes and bags.
A: It sounds like a wonderful idea, but I wonder how many people really shop there. I’m not sure most consumers would want to shop that way. It’s just not convenient.
Role-play Kevin and Alicia.
Listen again. Answer the questions.
1. What did Kevin see in the supermarket
He saw each coconut was wrapped in clear, thin plastic.
2. What does Kevin think about this
He think it is stupid and wasteful.
3. What solution does Alicia suggest

Listen to the conversation and answer the following questions.
1. What are Lisa and Amy talking about in their conversation
They are talking about how to become more environmentally aware.
2. What kind of wastes did they simply throw away that can be reused or recycled
They easily threw away newspapers and glass bottles.
3. Are they alone in action to protect the environment
No, there are lots of groups of people online who share ideas on how to reduce and recycle and who are committed to contributing to a better future for our planet.
Listen again and complete the table.
Wastes that can be reduced or reused What Amy and Lisa decide to do in the future
Plastic bags
Takeaway food packaging
Cartons and plastic cutlery
Newspapers and glass bottles
Buy reusable shopping bags
Cook at home
Tell restaurants not to give any plastic cutlery, chopsticks or paper plates
Sort rubbish and take them to a recycling centre
Role-play Lisa and Amy.
Two friends, Lisa and Amy are discussing how to become more environmentally aware.
A: It’s rubbish collection day tomorrow. I’ll put out our bins.
L: Wow, we have so much rubbish! l just get anxious when I think of the impact we have on the environment.
A: Me too! How can we have produced so much in just one week Look at all these plastic bags!
L: We really should buy reusable shopping bags when we go to the supermarket. That would be a good start to reduce our waste.
A: Let’s do it. I also notice how much takeaway food packaging we have. We should try to cook for ourselves more often. Look at all these cartons and plastic cutlery! Cooking at home is much more environmentally friendly.
Role-play Lisa and Amy.
L: Well, I’m a terrible cook so it might be hard for me to cook at home, but I think I will tell restaurants not to give me any plastic cutlery, chopsticks and paper plates when l order from now on.
A: That sounds like a good start. You know we are also quite bad at sorting our rubbish — look at this newspaper for example. It could easily be recycled but we threw it away.
L: And we threw away lots of glass bottles too. Let’s sort our rubbish and take it to a recycling centre from now on. The local council will help to reuse and recycle it.
A: Wonderful! I think these are all realistic and achievable steps that we can take to help protect the environment.
L: I’ve just looked online too and there are lots of groups we could join which share ideas on how to reduce and recycle. It feels good knowing that there are so many other people who are committed to contributing to a better future for our planet.
