基本的用法:
go to swim 语法:go to do sth
go swimming 语法:go doing sth 如go shopping
不可能是go to swimming,只可以是go to swim或go swimming.
be going to do sth 一般将来时的基本结构,只可以用to to.
I‘m going to swim.
to加动词不定式。
希望能帮助你。O(∩_∩)O~。望采纳。
i'm going to swim 或者 i'm going to go swimming
going to do Sth,或者是going swimming
前者,be going to +动词原形
