Passage One I don’t often lose things and I’m especially careful with money, so I was quite surprised when I reached for my wallet and it wasn’t there. At first, I thought it was possible that I could have left it at home. Then I remembered taking it out to pay for the taxi, so I knew I had it with me just before I walked into the restaurant. I wondered if it was possible that it could have slipped out of my pocket while I was eating dinner. Thinking about that possibility, I turned and walked back to the table where I had been sitting. Unfortunately, there were several people sitting at the table at the time, so I called a waiter and explained to him that my wallet had fallen out of my pocket while I was sitting at the table a few minutes earlier. I had the waiter go over to the table to see if my wallet was on the floor. While the waiter was looking for it, the manager of the restaurant came up to me and asked me if anything was wrong. I didn’t want to get a lot of people involved in the problem, but I knew I had to get the wallet back. I told the manager what had happened. He had me describe the wallet to him, and then he insisted that I report the missing wallet to the police. I told him that I didn’t particularly want to get the police involved in it; besides, I was in a hurry because I had an appointment with my doctor in just a few minutes. I explained to him that my biggest worry at the moment was how I was going to pay the check. He told me not to worry about that. He had me write down my name and address, and he said he would send me a bill. 1. Why was the writer so sure he had brought his wallet with him? A. He remembered that he didn’t leave it at home. B. He always felt his pocket for the wallet before he left home. C. He believed his own memory. D. He had taken it out to pay the taxi-driver. 2. According to the passage, the writer most probably lost his wallet when _____. A. he took it out to pay for the taxi B. he walked into the restaurant C. he was eating dinner D. he was ordering his dish 3. Why did the writer walk back to the table where he had been sitting? A. He was sure his wallet was still there. B. It was possible that he could find his wallet there. C. He could ask someone there about his wallet. D. He saw the wallet lying on the floor near the table. 4. As the writer didn’t want to get a lot of people involved in the problem, _____. A. he only told the manager what had happened B. he didn’t tell the manage anything C. he reported to the police immediately D. he only told the story to the manager and the waiter 5. Why did the manager tell the writer not to worry about paying the check? A. He was going to report the incident to the police. B. He could pay the doctor for the writer. C.
