Unit 1: A Picnic by the River

W: This is a good spot. Let’s stop and have our picnic next to the river.

M: Good idea. Walking always makes me hungry. I’m ready for lunch.

W: We can sit here on the grass. Oh no! Someone forgot to throw these empty paper bags away. There is litter everywhere!

M: Why do people always leave litter around? It’s not a nice thing to do. It spoils other people’s picnics.

W: I think they are lazy. Or maybe they just don’t care. Look, there are some empty cans and glass bottles under that tree, too.

M: People should clean up before they leave, and not leave litter lying around.

W: That’s right. Well, after our picnic, let’s pick up all the litter we can and take it out of here.

M: OK! And next week, let’s come back with friends and pick up some more.

W: Good idea!
