B 活动2a 听下列文章，茱莉亚和杰克都谈论了什么。
Hey, Julia. Don't forget to turn off the lights.
It saves electricity.
Oh, I know. I usually do that.
I was just in a hurry.
How come you're so interested in the environment, Jack?
I always have been.
Lots of people think there's nothing they can do,but I just read this book about it, and there are lots ofthings the average person can do.
Well, you should turn off the shower when you're washing your hair.
Oh, I'd never do that!
No, I have very short hair.
I'm only in the shower for a few minutes.
Well, every minute helps.
What else does it say?
It says you should take your own bags when you go food shopping.
Oh, that's not difficult.
I can do that. What else?
Hmmm. Here's a good one.
It says people should stop riding in cars and start riding bikes.
Oh, I'll never do that!
Can you see me riding 45 minutes to and from school every day?
Well, I think the environment is really important.
Besides, I like riding my bike.
Yes, and you also live close to school!
