When Dave was eighteen, he bought a secondhand car for 200 so that he could travel to and from work more__1__ than by bus. It worked quite well for a few years, but then it got so old, and it was costing him _2_much in repairs that he decided that he had better _3_it.

　He asked among his friends to see if anyone was particularly_ 4_ to buy a cheap car, but they all knew that it was falling to pieces, so_5_ of them had any desire to buy it. Dave's friend Sam saw that he was _6_ when they met one evening, and said, “What's _7_, Dave?”

Dave told him, and Sam answered, “Well, what about advertising it in the paper? You may _8_more for it that way than the cost of the advertisement!” Thinking that Sam's_9_was sensible(合理的),he put an advertisement in an evening paper, which read “For sale: small car, _10_ very little petrol, only two owners. Bargain at 50.”

For two days after the advertisement first appeared, there was no _11_.But then on Saturday evening he had an enquiry(询问).A man rang up and said he would like to_12_ him about the car. “All right,” Dave said, feeling happy. He asked the man whether ten o'clock the next morning would be_13_or not. “Fine,” the man said, “and I'll _14_my wife. We intend to go for a ride in it to _15_ it.”

The next morning, at a quarter to ten, Dave parked the car in the square outside his front door, _16_ to wait there for the people who had_17_ his advertisement. Even Dave had to _18_that the car really looked like a wreck(残骸).Then, soon after he had got the car as clean_19_ it could be, a police car stopped just behind him and a policeman got out. He looked at Dave's car and then said, “Have you reported this _20_ to us yet, sir?”
