I wonder if...?
1. I wonder if it would be convenient to visit you next Monday.
2. I wonder if Mr. Wang could arrange a meeting with me.
3. I was wondering if the manager would agree with my design.
4. I was wondering if you could come to the meeting this afternoon.
Saleman: Excuse me, Miss, I wonder if I could have a few minutes of your time?
Saleman: Well, I'd like to introduce you to the new super model ZX-2000 vacuum cleaner.
Woman: I'm sorry but I'm in a hurry now. I don't have time to try it out.
Saleman: That's no problem. Excuse me for interrupting you. Here, have my card.
Woman: Thanks. If I get a chance, I'll check out your vacuum cleaner another time.
