1) Hiking is hard work. Its very tiring.
2) I don't enjoy sunbathing. I find it boring.
3) I can't swim, so I won't ever go white water rafting because it will be dangerous.
4) I think fishing is very quiet and relaxing.
5) Julie and her sister will go scuba diving. Isn't that exciting?
6) I want to try sailing. I think it will be lots of fun.
