I'm not sure if Julia likes white. She ...... (not / appreciate) your gift, then.

We're not really certain whether the cook will make an omelette for all of us. He ...... (not / have) enough eggs in the fridge at the moment.

The janitor ...... (not / check) the pipes today. I don't really know but I suppose he's got too much work to do.

The Rogersons ...... (not / accept) our dinner invitation for Tuesday. I'm not entirely sure but I hear they are going away on holiday then.

The new computer ...... (not / work) perfectly now. I believe the operating system has not been loaded onto the computer yet.

You must be joking! Katie ...... (not / be) your mother. She's only thirteen years old.

You ...... (not / be) serious, Diana. That's a pack of lies you're telling.

The mountaineers ...... (not / return) to the cottage yet. If they had, they would already have given us a call.

I'm afraid Jason ...... (not / talk) to you right now. He's in a meeting.

Mr and Mrs Hudmat ...... (not / go) away on their honeymoon just now. They've been married for over six years now.
