帮我修改一下我的英语演讲稿包括常识上的错误 语法句子的错误 内容 结构 还有句子地不地道等

Hello everyone,my presentation today is mainly about recreation,【which】is the time spent to do things that will refresh your mind and body in a healthy and positive way。For example:Recreation,Fitness and Sports,Travel,Dance,Music,Television【,and so on。】The most popular recreational activities 【are】 fitness and sports。【Sports fall into serval catalogs as below：】 Aerobic activities,Conditioning activities,Strength activities,Individual sports,Racquet sports,Team sports,Outdoor sports,Water sports【,and so forth。】【Currently,there is a trend in the U。S】that people are getting more health conscious【,so they】 are exercising more for fitness。【The common sports people usually do are:】Bowling ,Running/Jogging ,Treadmill Exercise ,Stretching ,Fishing ,camping ,Hiking ,Walking for Fitness ,Billiards/Pool ,Boxing ,Darts ,Golf ,orseback Riding 【这里如果指的是起码的话,可以用equestrian】,Ice Skating ,Martial Arts ,Roller Skating ,Scooter Riding,Skateboarding,and some of the most popular sports that require teamworking are Football,basketball,Baseball,Hockey,and Soccer。Today more and more 【ladies】are beginning to participate in sports,【such as】 soccer,volley ball,【and】 basketball。They also watch sports games,【although not as many as men】。【The male audience is about two to three times as many as female audience。】 It was once considered to be improper for ladies to be involved in sports,but this has changed now。建议：楼主的listing太多,这样造成的后果一是读起来听众会觉得很无聊,再者也会令整篇文章的内容显得有点苍白。可以多结合一下实际的例子来阐述现况,譬如可以说说地方之间的受欢迎运动的不同：美国喜欢篮球、棒球、美式足球；英国足球最狂热,但是没人打篮球；中国乒乓球是国球,羽毛球、跳水等世界第一……然后可以分析一下为什么会出现这种现象。原因可以从场地、人文文化、体育发展趋势等方面来辩论。
