完形填空。 My husband hasn't stopped laughing about a funny thing that happened to me. It is funny now but it wasn't at that time. Last Friday, after 1 all family shopping in town, I wanted a rest 2 catching the train, so I bought a piece of newspaper and some chocolate and went into the 3 coffee shop-that cheap, self-service place with long tables to 4 . I put my heavy bag down on the floor, put the newspaper and chocolate on the table to keep 5 , and went to get a cup of coffee. When I came back with the coffee, there was someone in 6 . It was one of those wild-looking youngsters, 7 dark glasses and torn 8 , and hair colored bright red at the front. Not so unusual these days. What 9 surprise me was that he had started to eat my chocolate. Naturally, I was annoyed. 10 , to avoid trouble-and really I was rather 11 about him, I just looked down at the front page of the newspaper, tasted my coffee, and took a bit of chocolate. The boy looked at me closely. Then he took 12 piece of my chocolate. I could 13 believe it. Still I didn't dare to 14 an argument. When he took a third piece, I felt more 15 than uneasy. I thought, 'Well, I shall have the last piece.' And I got it. The boy 16 me a strange look, then stood up. As he left he shouted out, 'This 17 is crazy.' Everyone stared. That was embarrassing (令人难堪的) enough, but it was 18 when I finished my coffee and got ready to leave. My face went red-as red as 19 -when I realized I'd made a mistake. It wasn't my chocolate that he had been taking. There was mine, unopened, just 20 my newspaper. (     )1. A. buying (     )2. A. after (     )3. A. airport (     )4. A. sit on (     )5.
