Ann: Hallo, is that you, Mary? How are you? Why didn't you go to classes yesterday?Mary: Hallo, Ann. I felt very ill yesterday. I couldn't even get up.- What was the matter with you?- I don't know, I haven't seen the doctor yet. I had a high temperature.- Can you go to the Institute today?- No, I'm afraid I can't. The doctor's coming this morning. I feel I should stay in bed for a few days. I'm very sorry I have to miss several lectures.- That's all right. You mustn't come if you are ill. You should certainly stay in bed. You can have my notes if you like. Can I come to see you today?- Certainly. Please come round after classes.- I'm sorry, but I have to go to the library after classes to get some books for my talk.- Don't go to the library. I've got a lot of interesting books at home. You can take any of them.- All right. Can I get to your place be the 41 tram?- Yes, but don't come by tram. There's a new underground station near my house now. It takes me fifteen minutes to get to the Institute by underground.- Very good, and now I must hurry to the Institute. See you later.- Till this evening then. Don't forget to bring me your notes. Ring me up if you can't come.
