Specify, "have" in these proposals is to shock or unstressed?
1) they have not lived here for years.
2) he has a house near the river.
3) have you finished your work?
4) i've worked hard this week.
5) it has rained a lot this year.
6) i have a cat and a dog.
7) she's studied japanese, russian and english.
8) we have not seen her today.
9) have you got a minute?
10) someone has eaten my soup!

It seems to me that 2, 4, 6-8 are neutral. Also, I would say that the only sentences that have a stress on the auxiliary are the interogative sentences no. 3 and 9. Other than that, it is hard to tell that any short forms can be generally stressed.

1) They have not lived here for years.
In this proposal, it shocks. Because whoever you are telling this to expects that they lived there currently.

2) He has a house near the river.
This is unstressed.

3) Have you finished your work?
Also unstressed.

4) I've worked hard this week.
This would be shocked since the speaker is stressed from working so hard.

5) It has rained a lot this year.
It's shocked because the person is kind of stressed and shocked that it rained so much this year.

6) I have a cat and a dog.
Unstressed.

7) She's studied Japanese, Russian and English.
Unstressed.

8) We have not seen her today.
This is shocked. They expected the person you are asking to have seen her.

9) Have you got a minute?
Unstressed, if they were stressed or shocked they would have asked with more urgency.

10) Someone has eaten my soup!
Shock, the exclamation mark should give it to you that it is shocked.

Hope that helps :)
