M: Come in, Rose. Coffee?
W: Thank you, Jack.
M: How about the visit by the delegation from Poland?
W: Well, I still don’t get it. Do we know when they are coming?
M: [l]We offered them 3 choices. The end of March, the middle of April and the beginning of May.
W: Yeah.
M: [1]And they chose the earliest one, which is good because we are rather busy in May.
W: True. But we do need definite dates of their coming and how many are coming. There were six of them last time. Did they say eight this time? [2]My assistant needs to make a firm booking for their accommodations now. Otherwise it will be very difficult to find a hotel.
M: You are right They said six to eight originally, [3]but we got an E-mail this morning, saying it is going to be seven. Now we’ve got the definite number, we can make all the other bookings for them.
W: Good. That gives us eight weeks until they come.
M: Right. Here are my suggestions for their schedule. They will be with the university for five days. [4]On the first day, I think they should visit our campus. The second day we can show them around the downtown. This will give them a general picture of the changes in today’s China. And the last three days are for discussion and seminars.
W: OK. Do we need to invite some other famous professors from other universities?
M: That’s a good idea But no more than five are needed.
W: Right. I will arrange that.
