Hi! I’ve been wondering for some time if there is a rule in case of Let’s go +Verb structure.
Let’s go play tennis.
Let’s go swimming, shopping.
Is there a rule which states clearly when we add an -ing ending to the given verb.
I will be grateful for help.

How does this sound:
- “Let’s go do something” is used when two or more words follow “go”.
- “Let’s go doing” is used when the “doing” is expressed by one word only.
In addition, you can change the tense of “go” in “go doing”. For example:
- They have gone shopping. (present perfect)
- We went sightseeing. (past simple)
“Go do” is basically a shortened form of “go and do”. However, you can use “go do” only in the “go do” form. You can say these, for example:
- You should go get some sleep.
- We want to go see that movie.
- I will go find us some help.
- Mary told John to go jump in a lake.
You cannot say any of these:
[color=red]* He goes get some sleep.
- We went see the movie.
- I am going find us some help.
- John has gone jumped in a lake.
But you can say this, for example:
- We went and saw the movie.

Where have you been Amy? Good to see you back. 
Hi Daemon
Nice to see you, too.
Where have I been? Well, I also post on other ESL forums for one thing. My Yankee username was unceremoniously deactivated here last year, and it still doesn’t work. I guess the prospect of additional contributions from Yankee was and still is just too terrifying a thought for some people to deal with.
So, I don’t intend to post much here anymore. I may pop in occasionally under this new username – unless it ends up being deactivated too, that is.
Take care,
Amy
