I'm trying to identify sentence stresses, and im not sure how you would go about it. I seem to identify them, but it seems to me that the stresses would be different depending on how you say the sentence.

For example, with the following sentences:

1) Would you mind closing the window?

What would you say the stresses are? I think its "would", "closing", and "window".

2) His name's on the tip of my tongue

what would the stresses be here? I would say "name's", "tip", and "tongue".

3) She's a generous person

What are the stresses here? I would say "generous", and "person".

Have i correctly identified the stresses in each of the sentences? And if not, what are the stresses and why?

I would appreciate the help.
