M: Hi, Mary. Would you like to help save the environment?
W: Yes, I would, but what can I do?
M: Well, first, you can start by turning off the lights.
W: Yes, that’s easy. What’s next?
M: Then you can ride a bike. Don’t take a bus or a taxi if you don’t have to.
W: That will save money, too. What else?
M: Try to recycle paper.
W: Mm, newspapers, magazines, mail… We get a lot of paper at home. Good idea.
M:"And"also you can take a bag when you go shopping. Don’t use plastic bags.
W: OK. My parents do most of the shopping. I’ll tell them.
