There are different outdoor activities for different seasons. In spring we can fly kites. In summer, we can go swimming or sailing. In autumn, it is a good idea to camp or hike. In winter, we can go to ski or skate because they bring us a lot of fun. They make us strong and fit, too. So it is important for people of all ages to take part in some outdoor activities at the right time. There are many group activities, like football and basketball. The members work together for the same goal（目标）. So group activities need team spirit(团队精神). It is very useful for a person to have team spirit. It is good for us in life and work. Old people like walking and jogging. These outdoor activities don’t need much strength（气力）. Young people like exciting activities like diving（潜水）, skiing and horse riding. Children like fun activities like flying kites. Some outdoor activities are dangerous, like climbing rocks. So we must be careful when we take part in them.
