M：Hello, Mrs. Chris, may I come in?
W：Ah，come in Tom．Your report is interesting．There are a couple of things I’d like to check with you．You mentioned several countries you’d like to visit，Czechoslovakia again，Hungary，Romania，Singapore，the Gulf States． My first question：What’s the priority?
M：Well，they’re all potentially important．My feeling is that we should act fast．(19)I think a follow-up visit to Czechoslovakia is the priority．
W：OK．Next question．When do you want to go there?
M：I’ve got a lot of deskwork to finish off here．(20)I’d like to go towards the end of the month．
W：If we send you there，would you like to go to other eastern countries on the same trip?
M：Yes，certainly．Hungary and preferably Romania as well．
W：Why are you so keen on Romania? What’s going on there?
M：(21)I’ve heard that medical facilities are being expanded quite fast．Of course I’d have to do a good deal of market research．
W: Um, who would be our biggest competitors in Hungary and Roman a?
M: Surprisingly most of the stuff is in Albania. The Americans have got their feet in but only in a small way.
W: Another question. What will happen to our eastern countries business, if the pound got stronger?
M: It will have serious effect on exports, of course. But I don’t think we can miss this chance just because of that.
W: Then is the question of attitude. Media Papa seems very tough. Would they really have cancelled the order if we hadn’t delivered on time?
M: It’s hard to say. They are very tough, so maybe yes. (22)That’s why I want to go there again and strengthen our personal contacts.
