Text for Reading Comprehension №3

Nick was bored with life. Every day was exactly the same. He got up at exactly the same time; he caught the same bus to work; he did the same things in the office; he talked to the same people; he came home at the same time; he watched the same programmes on television — and he went to bed at the same time!

«What I need is a little adventure!» Nick thought as he waited at the bus-stop one morning. Nick's «little adventure» happened sooner than he expected!

While he was on the bus, reading his newspaper (the same one that he read every morning), the man sitting next to him suddenly pushed a large brown envelope into his hands. «Here, take this!» he muttered. Then he stood up and got off the bus before Nick could say a word.

Nick sat there, holding the envelope. It felt heavy. There were papers inside, or money perhaps. «I'd better hand it over to the police,» he thought. There was a police-station close to his office. But, as he got off the bus, a man approached him. He was obviously waiting for something. «He wants the envelope,» Nick thought. Nick began to walk quickly—and the man hurried after him. Nick started to run — and the man began to run too. But then, just before he got to the police station, Nick managed to lose the man in the crowds. When he entered the police station, the man was no longer in sight.

Inside the police-station, Nick handed over the envelope to the inspector in charge. The inspector opened it. The envelope was full of money —false money. «Obviously the man made a mistake,» the inspector said. «He thought you were one of the gang! Well, congratulations!»

Nick felt like a hero. He could already see his name in all the papers. He could imagine an interview on television!

«However,» the inspector went on, interrupting Nick's day-dreams, «I'm afraid I must ask you to keep quiet about all this. We're trying to catch some very clever thieves — and we don't want them to know that we have some of the money. So you mustn't say a word to anyone — not even your boss! Sorry!»

«So that's that!» Nick said to himself on his way to the office. He was over an hour late. «I' ve had my little adventure... but I can't tell anyone about it, so what's the point? I've even got to make up an excuse for the boss!»

1. Where did Nick work?

2. Why did the man give the envelope to Nick? What criminals were the police trying to catch?

3. Why did Nick feel disappointed after his «little adventure»?
