人教版九年级全册unit13 We’re trying to save the earth! SectionB 1a-1d.第3课时课件（该课件内含频文件）（该课件包含单词语句听力）
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!
