形填空（共20小题；每小题1分,满分20分） When Dave was eighteen, he bought a second-hand car for ￡200 so that he could travel to and from work more 36 than by bus. It worked quite well for a few years, but it got so old, and it was costing him 37 much in repairs, that he decided that he had better 38 it. He asked among his friends to see if anyone was 39 to buy a cheap car, but they all knew that it was falling to pieces, so 40 of them had any desire to buy it. Dave’s friend Sam saw that he was 41 when they met one evening, and said, “What’s 42 , Dave?” Dave told him, and Sam answered, “Well, what about advertising(登广告) it in the paper? You may 43 more for it in that way than the cost of the advertisement!” Thinking that Sam’s 44 was reasonable, he put an advertisement in an evening paper, which read: “For sale: small car, 45 very little gas, only two owners. Bargain at ￡50.” For two days after the advertisement first appeared, there was no 46. But then on the Saturday evening he had an enquiry (咨询). A man rang up and said he would like to 47 him about the car. “All right.” Dave said, feeling happy. He asked the man whether ten o’clock the next morning would be 48 or not. “Fine,” the man said, “and I’ll 49 my wife. We want to go for a ride in it to50 it.” The next morning, at a quarter to ten, Dave parked the car in the square outside his front door, 51 to wait there for the people who had 52 his advertisement. Even Dave had to 53 that the car really looked like a wreck (残破的车). Then, soon after he had got the car as 54 as 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 55 to us yet, sir?”
