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!
