I read an article about how sports events influence the climate last evening. It is said that the emissions from huge sports events can equal those of a country's, which shocked me when I heard it. I think that's why the Olympic Games have implemented a lot of policies to reduce emissions. This year's Olympic Games, I noticed that when audiences entered the stadium to watch the games, they only needed to show their E-tickets on their smartphones. It is a great way to reduce emissions and protect our environment. 昨晚我读了一篇关于运动活动如何影响气候的文章。它说一个大型运动会的排放物相当于一个国家的，当我听到这样说的时候我都被惊呆了。我想难怪奥林匹克运动都会实施一些政策去减少排放。这一届的奥运会我留意到当观众进入奥运场馆看比赛时，只需要出示其电子票就可以了，这是减少排放和保护环境相当不错的方式。
