Option1 : Debating
Divide the whole class into groups :
supporting the use of plastic packaging,
opposing the use of plastic packaging
neutral groups
according to their own wishes.
Students apply what they have learned to express their views by using examples, comparisons, etc.
Speaking
Online shopping is becoming more and more popular. However, it produces lots of unrecyclable packaging. What solutions do you have to this problem
Option 2: Express yourself.
Possible version:
I think as a consumer, we should choose to buy from the stores that use more recyclable packaging materials. We can also try combining orders and requiring items to be shipped together. I also suggest the online shop owners take packaging waste into consideration. They can give a packaging option that items are delivered with easy-to-open, recyclable packaging without any additional boxes or envelopes even on some additional charges.
Task 1. Review the words and expressions in Lesson 2.
Task 2. Finish exercise 7 and exercise 8 in the workbook on page 90.
