Indoor sports include activities like basketball, badminton, and gymnastics, which can be played all year round. They aren't affected by the seasons. Outdoor sports, such as soccer, rugby, and track and field, might be seasonal because of weather conditions. For example, it's hard to play soccer in the snow, so these sports might only be played during certain times of the year.
室内运动包括篮球、羽毛球和体操等活动,可以全年进行。不受季节影响。户外运动,如足球、橄榄球和田径,可能因天气条件而具有季节性。例如,在雪地里踢足球很困难,因此这些运动可能只能在一年中的某些时段进行。
