I am trying to explain to students how to use “join” . If there are any rules please let me know.
I’d like you to join us for lunch" is okay, but my students want to use constructions like
“Do you want to join me jogging”
and
“Do you want to join me in going to the movies”
I think Cantik made a good point and grammatically ‘join sb. in doing sth.’ is alright. e.g. The committee joins me in welcoming you. Sounds formal but correct. Cantik’s suggestion “Do you want to join me to the movies?” without ‘in going’ sounds better and naturaler to me although it’s alright to put in ‘in going’.
BTW, ‘join sb. doing sth.’ is grammatically wrong unless the speaker is well aware that the ‘in’ is deliberately omitted.
I have not posted because I can’t explain WHY those sentences sound so totally unnatural.
Would you like to join me when I go jogging?
Will you join me at the movies? Would you like to join me when I go to the movies tonight?
– Those are more natural versions.
