I'm going swimming还是I'm going swim

英语我将要去游泳,i'm going to swim还是i'm going to swimming 为什么 I'M GOING SWIMMING 不是 TO SWIM? “I'm going to swim now.”这样造句行吗? I'm going to swim in the r_.如何填空 I'm going to go swimming正确吗? I'm going to swimming.这句话有毛病吗? I'M GOING SWIMMING WITH MY PARENTS,是正在进行时还是将来时?怎么理解 i'm,going,higher i'm going home. I'm going to I like going swimming 还是I like to go swimming? i like go swimming 还是i like going swimming
