Section B, 1c, 1d

Jack: Turn off the lights, Julia. It saves electricity.

Julia: Oh, I usually do that. I was just in a hurry.

Jack: I see. I’ve just read a book which gives ideas about how we can save the environment. For example, you should turn off the shower when you’re washing your hair.

Julia: Oh, I would never do that. I have very short hair. It only takes a few minutes to wash. What else does it say?

Jack: You should take your own bags when you go shopping.

Julia: Oh, that’s easy. I’ll do that from now on. What else?

Jack: People should stop riding in cars and start riding bikes.

Julia: No way! It would take me 45 minutes to get to school by bike!

Jack: But it’s good for the environment! Besides, I like riding my bike.

Julia: Yes, and you also live close to school!

Step 4　Speaking

Work on 1e.

1. Ask the students to work in pairs. Make a conversation using the information from the chart above. Say what is true for them.

For example:

A: We really shouldn’t use paper napkins, you know.

B: I know. I stopped using them last year.

A: You should turn off the shower when you’re washing your hair.

B: Oh, I would never do that. It’s bad to waste water.

Encourage the students to suggest other things that people can do to help save the earth. Then use these new suggestions to make their conversations.
