I have two questions:
1. To express the same meaning as
"I don't like girls who smoke."
can I say
"I don't like girls smoking."?
It sounds kind of odd to me but I think it is not wrong.
2. To express the same meaning as
"She is a girl who smokes."
can I say
"She is a girl smoking."?
This one sounds somewhat odd to me too.
UPDATE: In some kinds of sentences, instead of pronouns like "who", "which" and "that", we can use the continuous form. So what I am asking is: Instead of using the version with "who", can I just use the continuous form in those sentences I gave.
An example of what I mean:
You can say "I love her face smiling at me every morning" instead of "I love her face that (which) smiles at me every morning"
Let's say a friend of yours is at your apartment, and you are talking about a bar with him. In that context, you can say "I like the girl singing at that bar." for meaning "I like the girl who sings at that bar." as far as I know.
