🏁参考答案：
A: Shall we start with fishing by the lake? What do you think about it?
B: Well, fishing is quite relaxing and quiet, but it might be a bit boring for Jerry if he wants to stay active. He won't get much exercise just sitting there. What about running instead?
A: I see your point. Running is definitely good exercise for staying fit, but honestly, it can be a little tiring and repetitive if he does it alone. How about cycling in the park?
B: That sounds like fun! He can enjoy the beautiful scenery and fresh air while pedaling. It’s perfect for fitness. What about hiking in the mountains?
A: Hiking is great for exploring nature, but it usually takes too much time and preparation for a regular weekend. What about skateboarding? It looks quite cool.
B: Skateboarding is definitely exciting, but it’s also a bit dangerous, especially if he hasn’t done it before. He might fall and hurt himself. What about boating on the river?
A: Boating is really relaxing, but it heavily depends on the weather. If it rains or gets too windy, it won't be safe or enjoyable at all.
B: You’re absolutely right. Looking at all the options, cycling in the park seems to balance fun, safety, and exercise perfectly. So, cycling is probably the best choice, isn’t it?
A: I totally agree with you. It's both active and safe. Let’s go with that!
