Hello,
I know that we can say:
play football, tennis....
go swimming, surfing....
do aerobics, judo.....
But, when making reference to all of them, without specifying any in particular, can we say: I like doing sports?
Thank you.
Doing sports is acceptable. However i'd say playing sports. It sounds better to me.
Hope it helps
For play, play a game (must be more than 1 people), example, play badminton, play football.
The sport that follows by do can be done alone, and at home. for example, do gymnastics, do yoga.
As for go, the sport that follows cant be done at home. and normally it is followed by ing. for example, go swimming, go fishing, go skiing.
hope this helps
Context is always important; labelling is rarely important.
Someone once told me a very general rule: if you keep score or if there's a way way to "win," you play it, and if there's no score, you do it.
I'm sure there are a lot of exceptions, but that's not a bad place to start.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
