Input:  Person1:     Would you like to go skiing with me ? I heard the new ski area is great . They have safe tracks , especially for the beginners and provide free training . I think it suits you best .  
 Person2:  Sounds not bad ! You know , the only thing I worried about is the safety . I ’ m not an active exerciser and my muscle may be not strong enough for such an intense sport .  
 Person1:      Then you can go to the three-day-long training camp first . There ’ re some professional teachers and they can guide you to do certain necessary exercise .  
 Person2:  I will think about it .  
 Person1:      Come on ! It is really a fun game .
