To-infinitive and a present participle

[korona21c]

I would like to know how I can change a relative clause to other forms.


The first sentence of each set is what I want to express. So, the second and third one should be equal to the first one. I would like to confirm whether I can change the relative clause to to-Infinitive or a present participle as what I did.

Thanks.

I don't believe the last construction is possible. At least not with this particular example.

Again, the other two wouldn't sound right.


This last one is a bit interesting because all of them work, but mean different things.

You love the guy who sings well. (You love the guy who is identified as a good singer.)

You love the guy to sing well. (It's a bit of a funny construction, but one could say it to imply that he/she enjoys it when the guy sings well. Although it does sound a bit funny in this context.)

You love the guy singing well. (You love the guy who is currently singing well at this very moment.)
