Do you often use plastic packets and boxes
What are the advantages and disadvantages of using them
Use the words and phrases to help you.
A lot of things we buy in the supermarket are in plastic packets and boxes. It’s convenient to buy meat or fruit or vegetables that are in packets or boxes because it makes shopping quicker and it keeps the products fresh and helps it last longer. However, it is wasteful as most people don’t recycle the packets.
Activity 2
You are going to listen to two people, Kevin and Alicia, talking about plastic packets.
Use the Skill Builder to decide whose opinion each statement is from.
Write K (Kevin) or A (Alicia).
1 It is stupid to wrap coconuts in plastic. ( )
2 Plastic packaging keeps the product fresh. ( )
3 Plastic packaging is bad for the environment. ( )
4 The packaging should be recyclable. ( )
5 We should do away with packaging completely. ( )
6 Refillable containers are not convenient. ( )
Identifying Opinions
People can have different opinions on the same topics. It’s important to study these opinions, so that you can identify and understand the arguments for and against these important issues.
As you listen, identify the “topic” words or expressions of opinions and write down any opinion words you hear.
Pay attention to the intonation used when agreeing and disagreeing.

Plastic packaging
Kevin: Against Alicia: For
Each coconut was wrapped in clear, thin plastic. Isn’t this the most stupid example of packaging ever But it’s completely wasteful and unnecessary. It already has its own natural packaging. It’s got a tough shell that’s almost impossible to break! 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. 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, the product will last longer.
But the plastic wrapping also has other uses. It stops coconut hairs from getting into other food during transport. And it keeps the coconut clean.
But let’s be realistic: We still need packaging. We just need to use the right kind of packaging.
Listen again and decide if they are for or against plastic packaging and find out their reasons.

听力原文
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!
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: 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.
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: 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.

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.
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.
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: 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.
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.

【句式剖析】
本句中的so that意为“以便，为了”，在句中引导一个表示目的的状语从句。
【句式提升】
在使用so that引导目的状语从句的时候，我们应注意如下几点：
1. so that 引导目的状语从句时，表示“以便，为了”。此时，从句谓语常含有should, would, could, might, can等情态动词。其同义短语in order that也引导目的状语从句，但 so that一般不用于句首，而in order that可用于句首。
例句1. Bring it closer, so that / in order that I can see it more clearly.
拿近一些，好让我看得更清楚。
例句2. In order that she could catch the first bus, she got up very early.
为了能够赶上第一班公共汽车，她起得很早。
句式精讲
【句式提升】
在使用so that引导目的状语从句的时候，我们应注意如下几点：
2. 当so that/in order that引导的从句中的主语和主句中的主语一致时，可将从句转化为不定式或“in order to/so as to”结构。注意：so as to不能放在句首，而in order to可放在句首。
例句3. We must study hard so that/in order that we could realize our dreams.
＝In order that we could realize our dreams, we must study hard.
＝We must study hard so as to/in order to/to realize our dreams.
