完形填空

Like most English children, I learned foreign languages at 36. When I made my first visit 37 the Unites States, I was 38 I could have a nice easy holiday without any 39 problem. But how 40 I was!
At the American airport, I was looking for a public telephone to 41 my friend Jenny I had 41 . A worker asked if he could 43 me. “Yes,” I said. “I want to give my friend a ring.” “Well, that’s nice. Are you getting married?” he asked. “No,” I answered. “I just want to tell her 44 the phone I have arrived.” “Oh,” he said, “there is a 45 downstairs on the first floor.” “But we’re on the first floor now,” I said. “Well, I don’t know what you are 46 about. Maybe you aren’t feeling too well after your 47,” he said. “You just go and wash up, and you will feel a lot better.” And he went 48 , 49 me wondering where on earth I was: at home we wash up after a 50 to get the cups and plates clean. How can I wash up at an airport?
At last we did 51. She 52 the misunderstanding(误会): American say “to give someone a 53 ”, but we English say “ to give someone a ring”. When we say “to wash your hands”, they say “to wash 54”. And Englishmen start numbering from the floor, so the 55 floor is the second for Americans.
