W: So Mr. Brown, this is your bed, and as you can see, there are three other beds in the ward(²¡·¿). Have you __1__(get) everything you need?

M: Yes, nurse, I think 2 . I followed the hospital¡¯s advice, and I¡¯ve only brought a few 3 (belong) with me.

W: Good, you can see the reasons 4 we ask you to do that, the cupboard is 5 (real) very small.

M: Yes. Nurse, can you tell me what the visiting hours are?

W: Yes, of course. They are in the afternoon from 2:30 to 4:30 and in the evening from 7:00 6 8:00, but remember that only two people can see you at the same time.

M: I see. What other rules are there?

W: Yes. We start pretty early. We wake you at 6 o¡¯clock, and breakfast is at 8 o¡¯clock, lunch is at noon, there is tea at 3:30, and supper is at 6 o¡¯clock.

M: Oh, that¡¯s very 7 (difference) from what I have been used to. You¡¯d better tell me the rest of the rules here.

W: Yes. Well, you can see the no 8 (smoke) sign. We don¡¯t allow smoking in the wards, and the same __9__ (go) for alcohol. However, if you 10 (need) to smoke, there are special rooms.

M: Oh, I don¡¯t smoke, so it doesn¡¯t affect me.

W: Good.
