DictationTom King could feel Sandel growing stronger against him. He saw youth recuperate. From instant to instant Sandel grew stronger. His punches, weak at first, became strong. Tom King saw the gloved fist driving at his jaw, and wanted to guard it by raising his arm. But the arm was too heavy. It would not lift itself. Then the gloved fist landed home. Tom felt a sharp snap and blacked out.When he opened his eyes again he was in his corner, and he heard the audience screaming and cheering. His second was blowing cold water over his face and chest. His gloves had already been removed, and Sandel, bending over him, was shaking his hand. He bore no ill will toward the man who had put him out, and he returned the grip with heartiness. King felt hungry. He remembered back into the fight to the moment when he almost defeated Sandel. Ah, that piece of steak would have done it!

Sumo: the object of a sumo contest is to push an opponent out of the ring or force him to the floor.4. Professional wrestling: professional wrestlers perform stunts and muscular feats for the benefitof an audience.Script:WrestlingWrestling is a body-contact sport between two athletes in which each tries to throw the other down and pin his shoulders to the mat or ground for one second. At the beginning of a standard wrestling contest the participants approach each other and begin to attack each other. Each wrestler tries to surprise the other with a takedown, a movement designed to throw the opponent off balance and to the ground. To perform a takedown, the wrestler darts behind his opponent by ducking under his arm, grabbing his opponent’s arms or legs and throwing him to the ground. Once a wrestler has been thrown down, his opponent tries to keep him down. Meanwhile, the fallen wrestler uses many defensive movements to free himself and to gain the top position. Wrestling contests are usually held on soft mats to protect wrestlers from serious injury.Wrestling is one of the oldest sports known to man. It undoubtedly had its beginnings in man’s early struggle for survival, and it developed independently in widely separated civilizations of the ancient world. Paintings found on the walls of Egyptian tombs indicate that wrestling was a popular sport in Egypt more than 5,000 years ago. In ancient Greece, wrestling contests were important events at victory celebrations and, later, at the Olympic Games. Greek wrestling was adopted and then formalized by the ancient Romans.Although competitive athletics were generally neglected after the termination of the Olympic Games in 394 A.D., wrestling contests remained popular amusements during the Middle Ages, particularly at the courts of England and France.Today there are four main types of organized wrestling: Greco-Roman, catch-as-catch-can, sumo, and professional wrestling. Although they all have characteristics in common, each differs considerably from the others in style and rules.In Greco-Roman wrestling the wrestler is not allowed to use his legs on his opponent and cannot hold him below the waist. Patterned after older English wrestling forms, the Greco-Roman style is practised mainly in Europe.Catch-as-catch-can, also known as freestyle wrestling, is probably the most popular form of modern wrestling. In general, holds are allowed on all parts of the body, but kicking, striking, and other such injurious tactics are strictly prohibited.Sumo is a traditional form of wrestling that has been practised in Japan for more than 2,200 years. Sumo matches are held in small sanded rings bound by rice straw. The object of a sumo contest is to push an opponent out of the ring or force him to the floor. Sumo wrestlers often weigh more than 136 kilogrammes.Professional wrestling, which is sometimes classified as sport, has become more of a stagedentertainment than a spontaneous competition. Professional wrestlers perform stunt and muscular feats for the benefit of an audience.4. TranslationA. Translate the following sentences from Chinese into English.1. 电视转播了那个初出茅庐的新闻记者成功地采访好莱坞电影明星的节目。

DictationMany students who call themselves bad readers nevertheless do read some things successfully. They may read novels or they may read the sports page every day. But a textbook is a different matter. A textbook gives them a lot of trouble. Why is that? One reason is lack of interest. Another is that they are often unfamiliar with the subject about which they are reading. But a third reason is that they try to read a textbook as if it were a novel or a sports story or a problem to be solved by Ann Landers. They respond to the textbook inappropriately.How you read something depends on the author’s purpose in writing. There are basically four purposes for writing. Some authors write to tell a story; others write to create an image in your mind; some write to inform or teach; and still others write to convince you of a particular viewpoint. Each of these four purposes requires a different response as you read. If you respond differently to different types of writing, you will find thatyour reading will be much easier.3. Listening ComprehensionA. True (T) or False (F)?For false statements, write the facts.1.The man was on his way to a country village when he hearda strange noise coming frombehind his car.FThe man was on his way from a country village to London.2.He examined the back of the car carefully, but found nothing wrong.FHe examined the wheels carefully, but found nothing wrong.3.When he turned his head, he found many bees following his car.T4.He soon knew that a queen been and her followers had hidden in his car.FHe soon knew that a queen bee had hidden in his car.5.The man was very surprised when a policeman arrived.FThe man telephoned the police and explained what had happened. But no policemen arrived on the scene.6.The bee-keeper was very happy because he had been able to help the motorist.FThe bee-keeper was very happy because he had received an unexpected gift — a big box fullof bees — from the motorist.B. Arrange the following sentences according to the order of happening.1. A bee-keeper finally helped the man to solve the problem.2. He soon found thousands of bees near his car.3. He arrived at a hotel in London where he had a drink.4. The man stopped his car when he heard a strange noise.5. He drove as quickly as he could to get rid of the bees.6. As he couldn’t find anything wrong with his car, he went on his way.7. A customer hurried in to tell him that his car was covered with bees.The correct order of the sentences: 4 6 2 5 3 7 1Script:An Unwelcome PassengerHidden passengers travelling in ships, trains, or even cars can be a terrible nuisance —especially when they are insects. In this respect, there is a great difference between human beings and insects. The former make every possible effort to avoid discovery, while the latter quickly draw attention to themselves.We can only sympathize with the unfortunate man who had to stop his car soon after setting out from a country village to drive to London. Hearing a strange noise from the back of the car, he naturally got out to have a look. He examined the wheels carefully but as he found nothing wrong, he continued his way. The noise began almost immediately and now it was louder than ever. Quickly turning his head, the man saw what appeared to be a great black cloud following the car. When he stopped at a village further on, he was told that a queen bee must be hidden in his car as there were thousands of bees nearby.On learning this, the man realized that the only way toescape would be to drive away as quickly as possible. After an hour’s hard driving, he arrived in London where he parked his car outside a hotel and went in to have a drink. It was not long before a customer who had seen him arrive hurried in to inform him that his car was covered with bees. The poor motorist telephoned the police and explained what had happened. The police decided that the best way to deal with the situation would be to call a bee-keeper. In a short time, the bee-keeper arrived. He found the unwelcome passenger hidden near the wheels at the back of the car. Very grateful to the motorist for this unexpected gift, the keeper took the queen and her thousands of followers home in a large box. Equally grateful, the motorist drove away in peace, at last fre e from the “black cloud” which had hung over his car.4. TranslationA. Translate the following sentences from Chinese into English.1. 看到敌机飞近,他们飞奔开去,寻找可以躲避炸弹的掩蔽处。
