[speaker001:] I don 't understand why you always look so happy, so energetic. It seems like you 'Ve got good news everyday.
[speaker002:] Really? Do I look happy all the time?
[speaker001:] All I know is you look quite differently from other teachers.
[speaker002:] Oh, do you know why? Actually, it 's easy. Because I always exercise. My exercise, I think, is very hard. I often feel very good after conquering these difficulties. I feel alive!
[speaker001:] Oh, I know. I saw you doing pull-ups one time on the campus and some students trying to imitate you.
[speaker002:] Yeah, they are doing it for fun. Seldom would people like my exercise. It 's difficult and boring.
[speaker001:] It 's true. Many students do the exercise when they have to. We have P. E. once a week.
[speaker002:] But I think Chinese students need to exercise more. Besides exercise will help them learn new things better. Don 't students want to have a good memory?
[speaker001:] Of course. I didn 't know that. I only know exercise makes bodies stronger. I should take some exercise then. Do you have any suggestions?
[speaker002:] Well, do what you like to do. It can be anything. Jogging, doing aerobics, going bicycling, and playing ping-pong. Absolutely anything. Doing three or more workouts a week is good for you. But remember to do some stretches first.
[speaker001:] Oh, I know. Thank you.
