Jack: Hi Henry! I guess we need to think about how to keep our class clean. Look at our classroom, it looks dirty. What do you think?
Henry: You’re definitely right! We should warn our friends about it. Do you have any ideas?
Jack: We can make a presentation about how to keep our class tidy and neat. Also, we can choose two volunteer students to be responsible for warning others.
Henry: Great idea!! What can we talk about during our presentation?
Jack: For example, we must put any rubbish in the bin, and we must keep our tables clean and tidy.
Henry: You’re right! Also, we mustn’t damage any school objects, like drawing on the walls.
Jack: Moreover, we can create posters in our Art class, and we can write slogans like “This is our second home, we need to keep it clean!”
Henry: I totally agree with you! We can stick them on the walls so that everyone can see.
