Hey , Steven . What are you going to do this Saturday ?   If the weather is good , I'll go to climb mountains .   Are you going with your friends ?   No , I'm going alone .   Oh , aren't you afraid ?   Of course not . For me , mountaineering is both relaxation and a hobby .   I think mountaineering is an exciting sport , but a little dangerous .   Yeah , you are right , but it's really interesting .
