Health is significant for all of us.And people who take part in sports must be in condition.Everyone in my family still stay healthy through sports.For my father,nothing is more exciting than playing football.Running is very economical and easy,so nothing is fitter than running for my mother.And table tennis is my brother's favorite sport because he thinks it is interesting and poular.And I love bicycle riding for making me relaxed.
Significant:重要的,有意义的
People who take part in sports must be in condition :参加运动的人一定能保持良好的健康状态.
Than 后面要接名词或动名词,所以用了"playing "和 "running"
Economical:节约的,经济的,合算的
最后一句里的“for”在句中表原因,是介词,所以后接动名词.
