Julia , look at me ! I'm gaining weight . How could I lose weight ? Do you have any good ideas ?   Since summer is coming , I think swimming is a good way for you to do .   Are you sure ?   Of course ! Swimming can help you stay in shape by targeting all parts of your body .   Really ? Does swimming have other advantages ?   It could also help you increase vital capacity .   That ’ s great . Okay , from now on I would swim three times a week . I hope I can get rid of the weight .   You will make it if you persist in it .
