PPAULO escreveu:Yes, the grammatically correct is, after a verb the pronoun should be an object pronoun (me, you, him, her...etc)
In informal terms, certainly the ones above might come up.
So, the grammarly correct ways would be:
I saw him talking to...
I saw him talking about...
In an exam one should never consider those as correct form.
Not necessarily. If followed by a gerund (instead of a participle as in your example), the correct form is a possessive pronoun.
1. Sarah was surprised at your
leaving early --> Sarah is not suprised at you. She is surprised at the "leaving early" part
2. I appreciate your
taking the time to read our year-end report
3. That baby’s
crying is getting on my nerves --> The baby is cute, he doesn't get on my nerves. The problem is his crying.
So, if the action is the thing that is being liked/appreciated/praised/etc, (the leaving early, the taking the time or the crying), you should use the possessive pronoun .
In the case of the phrase "I saw him talking to (the waiter)", I want to say that I saw HIM (who was talking to the waiter). On the other hand, if I wanted to say that I liked that he went there and talked to the waiter for me, I would have to say "I appreciate his talking to the waiter", since I appreciate the action of TALKING, not the person.
So, Marcos' examples
Marcos22 escreveu:"I saw Sally running"
means that he saw Sally and she was running (and that's why he used the present participle). If he had written "I saw Sally's
running" (using the gerund), the emphasis would be on the action of running (e.g. I saw Sally's running, and it is so funny!).
It can, however, be very awkward sometimes: "The mother hates the baby
crying" means she doesn't like the kid (what kind of mother is that??). The speaker probably meant "The mother hates the baby's
I also have to say that, in spoken English, the distinction is rarely used. Usually people stick with the participle (using the object pronouns), but in formal writing it is still used.
