I don ’ t understand why you always look so happy , so energetic . It seems like you ’ Ve got good news everyday .

All I know is you look quite differently from other teachers .

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 !

Oh , I know . I saw you doing pull-ups one time on the campus 5 and some students trying to imitate you .

Yeah , they are doing it for fun . Seldom would people like my exercise . It ’ s difficult and boring .

It ’ s true . Many students do the exercise when they have to . We have P . E . once a week .

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 ?

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 ?

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 .
