Would

Anonymous I was so bored and depressed. I didn't have a car. So, I couldn't go anywhere while I was there. Nobody would give me a ride. That was a bad time.

Yes, the use of would is correct.

Does would mean past habit here?

I see it as simply the past of will.

And can I also use would have?if not, what's the reason?

You could say Nobody would have given me a ride, but it would change the meaning. It would make it a conditional statement, nobody would have given you a ride if you had wanted one/asked for one. The original statement suggests that you did want a ride (or asked for a ride), but they all refused to give you one.

The original passage is not quite right. The third sentence should be: "So I couldn't go anywhere while I was there."

If you change the fourth sentence to: "Nobody would have given [not "give"] me a ride.", this is grammatical, but syntax is then no longer right. You'd have to say, instead, something like: "Nobody would have given me a ride, if I asked."

I am pretty sure. 'would' was used in the sentence to show past habit. How could it be past of will? Nobody would give me a ride, it means each time I needed a ride, nobody would give me a ride. Am I right?

To me, it seems odd to regard something that doesn't happen as a habit.
He wanted to go to the airport today, but nobody would give him a ride (past tense of will. Compare: He wants to go to the airport today, but nobody will give him a ride.).
Every morning I would give her a ride to work, and every morning she would offer me a dollar for gas, whic

AnonymousNobody would give me a ride.

Yes. 'would' is correct there. Nobody [would / was willing to] give me a ride.

so what if I was looking for a ride for many days, I mean 5 or 6 times and nobody gave me a ride. Can't I still say,'nobody would give me a ride while I was there'?
