Have any plans for the weekend , Tom ?   Yes . I am going for a hike around the Qinghai Lake .   Oh , do you go hiking often ?   I go as much as I can . I love hiking , because you can really get in touch with nature .   It would be nice to get out of the city . Do you want some company ?   Sure . But it will be a long hike 30 miles in three days . Have you been hiking before ?   Yeah , I go a lot too . I saw a bear and a lion on my last hike .   Wow . You must have been pretty far away from the city .
