Rewrite the underlined parts of this phone conversation, using will, won't, would and wouldn't, as in the example.
JAKE Hi, Alice, how nice to hear from you!
ALICE Actually, Jake, I'm phoning to ask you for some advice.
JAKE (0) I'm willing to help you if I can, of course.
ALICE Your mother receives help from the Council, doesn't she? Can you tell me what
(1) they agree to do and what (2) they don't agree to do for older people?
JAKE Yes, of course. Mum has a home help. She comes three times a week.
(3) She's perfectly happy to do light cleaning and (4) she's willing to get the shopping, but (5) she refuses to do anything heavy.
ALICE That's fair enough. What about cooking?
JAKE Well, when she first started (6) she was happy to prepare supper when she came,
but she stopped that after a few weeks.
ALICE Why was that?
JAKE You know my mum. (7) She insists on saying exactly what she thinks.
Apparently, the home help used to make vegetarian food and Mum didn't like it, so (8) she refused to eat it. Why are you asking, anyway?
ALICE It's Dad. He can't move around very easily now. The neighbours are great,
(9) they make a habit of popping in but (10) he's unwilling to ask them for help.
JAKE Mmm. You can understand that.
ALICE Oh, but he's so impatient. I take him to the shops once a week, but yesterday
(11) the car refused to start and I was about half an hour late. (12) Was he willing to wait for me? No, (13) he insists on trying to cope by himself!
He went to the shops and collapsed on the way there.
JAKE Oh dear. It's a worry, isn't it? Look, if (14) you don't mind waiting for a moment,
I'll look up the phone number for the right person at social services.
