I have a question !!!

1. It's a wonderful book. I (enjoy ) every moment of it.
2. We've always wanted a house in the country, but we ( disagree) on where it should be.
3. Can you give me some detailed information about the use of state verbs ( esp when should we use the present continuous with them?) though I read in a book written by Martin Hewings.
4. I had an excercise like that :
Mary : I don't think your brother ( enjoy ) the party. He ( keep) looking at his watch.
Susan : No, I'm sure he (enjoy ) it. He always enjoys your parties. I know that he wants to go home early tonight because he is expecting a phone call.


Many thanks.
