temperatures. Tazieff has often risked his life in this way. He has been able to tell us more about active volcanoes than any man alive. Lesson68 Persistent 纠缠不休I crossed the street to avoid meeting him, but he saw me and came running towards me. It was no use pretending that I had not seen him, so I waved to him. I never enjoy meeting Bert Dykes. He never has anything to do. No matter how busy you are, he always insists on coming with you. I had to think of a way of preventing him from following me around all morning.Hullo, Bert, I said. Fancy meeting you here !Hullo, Elizabeth, Bert answered. I was just wondering how to spend the morning-until I saw you. Youre not busy doing anything, are you ? No, not at all, I answered. Im going to. .Would you mind my coming with you ? he asked, before I had finished speaking. Not at all, I lied, but Im going to the dentist. Then Ill come with you, he answered. Theres always plenty to read in the waiting room !lesson69 But not murder! 并非谋杀！I was being tested for a driving licence for the third time. I had been asked to drive in heavy traffic and had done so successfully. After having been instructed to drive out of town, I began to acquire confidence. Sure that I had passed, I was almost beginning to enjoy my test. The examiner must have been pleased with my performance, for he smiled and said, Just one more thing, Mr Eames. Let us suppose that a child suddenly crosses the road in front of you. As soon as I tap on the window, I want the car to be stopped immediately. I continued driving and after some time, the examiner tapped loudly. Though the sound could be heard clearly, it took me a long time to react. I suddenly pressed the brake pedal hard and we were both thrown forward. The examiner looked at me sadly. Mr Eames, he said, in a mournful voice, you have just killed that child ! lesson70 Red for danger 危险的红色During a bullfight, a drunk suddenly wandered into the middle of the ring. The crowd began to shout, but the drunk was unaware of the danger. The bull was busy with the matador at the time, but it suddenly caught sight of the drunk who was shouting rude remarks and waving a red cap. Apparently sensitive to criticism, the bull forgot all about the matador and charged at the drunk. The crowd suddenly grew quiet. The drunk, however, seemed quite sure of himself. When the bull got close to him, he clumsily stepped aside to let it pass. The crowd broke into cheers and the drunk bowed. By this time, however, three men had come into the ring and they quickly dragged the drunk to safety. Even the bull seemed to feel sorry for him, for it looked on sympathetically until the drunk was out of the way before once more turning its attention to the matador.Lesson71 A famous clock 一个著名的大钟When you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard all over the world on the B.B.C. If the Houses of Parliament had hot been burned down in 1834, the great clock would never have been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down ! Lesson72 A car called Bluebird “蓝鸟”汽车The great racing driver, Sir Malcolm Campbell, was the first man to drive at over 300 miles per hour. He set up a new world record in September 1935 at Bonneville Salt Flats, Utah. Bluebird, the car he was driving, had been specially built for him. It was over 30 feet in length and had a 2500 horse-power engine. Although Campbell reached a speed of over 304 miles per hour, he had great difficulty in controlling the car because a tyre burst during the first run. After his attempt, Campbell was disappointed to learn that his average speed had been 299 miles per hour. However, a few days later, he was told that a mistake had been made. His average speed had been 301 miles per hour. Since that time, racing drivers have reached speeds of over 400 miles an hour. Following his fathers footsteps many years later, Sir Malcolms son, Donald, also set up a world record. Like his father, he was driving a car called Bluebird.Lesson73 The record-holder 纪录保持者Little boys who play truant from school are unimaginative. A quiet days fishing, or eight hours in a cinema seeing the same film over and over again, is usually as far as they get. They have all been put to shame by a boy who, while playing truant, travelled 1600 miles. He hitch- hiked to Dover and, towards evening, went
