[speaker001:] Hi, Steven! What do you like to do during the weekend?
[speaker002:] I love swimming and cycling. On Saturday morning I usually ride my bike around the city or the country road for almost two hours.
[speaker001:] That 's great! I think they do you a lot of good.
[speaker002:] Sure, they do.
[speaker001:] But why do you choose cycling at first?
[speaker002:] Because it is convenient and good for environmental protection.
[speaker001:] You are really a good citizen.
[speaker002:] That 's what I can do.
