题型:单项选择题 A1型题
It was lunchtime and I walked into a small branch bank on the West Side. I had come to   1  a checking account. The only officer on   2  was a fortyish black man, standing   3  a small counter from a young white boy who was wearing a V-necked sweater. I thought I was especially   4  of the boy because he looked more like from a prep school than a   5  in a West Side bank.
The boy continued to   6  my attention because of what happened next. He was holding an open savings-account book and   7  an expression of disappointment. “But I don’t understand. I opened the account myself, so why can’t I   8  any money?” the boy said, his voice breaking.
“I know it is, but those are the rules. I’ve already explained to you that a fourteen-year-old is not   9  to withdraw money without a letter from his parents,” the officer explained patiently.
Suddenly I noticed the   10  had a series of small deposits (存款) and withdraws. Then I questioned the officer, “How do you   11  that? Why did you let him withdraw money before, but not now?” He looked   12 . “Because the tellers were not aware of his age before and now they are. It’s really very   13 .” I turned to the boy with a shrug. “You’re really getting   14 ,” I said. “You ought to get your parents to come here and protest.” The boy looked destroyed.   15 , he put his savings book in a rear-pocket and walked out of the bank.
The officer turned to me. “You know,” he said, “you really shouldn’t have got   16 .” I couldn’t believe what he was saying. “We were   17  this morning that some neighborhood bully has been shaking down (敲诈) this boy for more than a month. The guy was   18  him to take money out every week and hand it over. The poor kid was   19  too scared to tell anyone. Anyway, the police are on the case and they’ll probably make a(n)   20  today.”
“You mean there is no rule about being too young to withdraw money from a savings account?”
“Not that I ever heard of. Now, sir, what can we do for you?”
