regularly和on a regular basis有什么区别?

问题补充说明：两句话:I am a sports-lover who take part in basketball and swimming regularly.修改后:I love sports and participate in basketball and swimming on a regular basis.那么，regularly 和on a regular basis 有什么区别?

两个意思都差不多，regularly一般用在非正式场合，特别是口责讨分吧语，而onaregularbasis用在正式场合比较多，比如我们公司对某个问题的分析就用onaregularbasis，而不用regularly
