【正文】 the US carmakers? 3. Who is David Champion? 4. Which of the following is NOT true according to the talk? UNIT 4 A UFO in My Yard (Part One) It was one . one cold fall night in 1968. I was 21 then, and was ing home from a date. I had just dropped off my girlfriend and was heading back to Franksville, a rural town in Wisconsin. As I turned left to go east on Seven Mile Road, I saw extremely bright lights streaming out from the distance. My heart skipped a beat. What was producing these strange lights visible from a half mile away? I thought it was a house on fire. The lights seemed to emanate from the area where my house was located. My parents and two brothers were probably in bed by now. As I accelerated and turned onto the town street, frantic thoughts ran through my mind. Was the house burning down? Was my family trapped inside? As I raced toward my house, I noticed that the yards of my house and my neighbors39。s center. Both cones seemed to be made of a glasslike material. The top cone was white, while the bottom cone glowed yellow. White lights circled the yellow cone on the underside of the craft. Each light was about 34 feet in diameter. It didn39。s advice and go to bed. Somehow I fell asleep. The next day life went on as usual. I have repeatedly asked my family members about what happened that night, but none has ever recalled anything out of the ordinary. I thought about telling the police, but feared they would think I was crazy, if I said I had seen a UFO the other night. I can39。 visit to the family according to the narrator? 3. How many people were there in the narrator39。ve all heard the saying Laughter is the best medicine. How important is it to our health, Dr. Berk? M: This saying has been scientifically proven! According to our research, laughter strengthens the immune system and lowers the levels of stress hormones ... W: Can you be more specific? M: Well, after a bout of laughter, blood pressure drops to a lower, healthier level than when the laughter began. Dr. William Fry of Stanford University found that twenty seconds of guffawing gives the heart the same workout as three minutes of hard rowing. W: What else? M: Another yearlong study of heart attack victims done at the Oakhurst Health Research Institute in California found that of those patients who spent half an hour a day watching edy videos, 10 percent had a second heart attack, whereas 30 percent of those who did not watch had a second attack. W: Wow! Laughter is really a good medicine to patients. Can you give us another example? M: Sure! Norman Cousins, editor of the Saturday Review, learned this during a battle with a debilitating illness. He discovered that his condition improved when he enjoyed himself and watched funny movies. Laughing, he wrote, is like inner jogging. It helps us heal by activating the immune system. Many sick people have taken his advice and incorporated humor into their recovery regimen by watching edies or reading collections of jokes. W: You said Norman learned this? Do we have to learn to laugh? M: Not necessarily. Since laughing is something people can do sitting down, costs no money, and requires no special exercise equipment or skill, it39。s easy. You take a deep breath, smile, exhale, and say Aaah while visualizing all your muscles and cells smiling. Then add to that a memory of a time you felt really good and laughed and laughed. W: What about the situation in which you aren39。ve learned it! And thank you for joining us to talk about laughing. M: My pleasure. Questions: 1. Who is the man? 2. What will happen to a person after a bout of laughter? 3. Why is laughter considered to be the perfect workout for all people? 4. Why would it be good for us to fake a smile o。s the real thing, because your mind is smart, but your body is stupid and can39。t have the time or desire to participate in a regular fitness program. W: Oh, I see. Do you have such a program to offer to the general public? M: Yes, we do. It39。t the narrator report the saucer incident to the police? 6. Why did the narrator want to receive hypnotic treatment one day? Were They UFOs? What was the cause of these lights traveling across the sky in this remote area of South America? The following year, similar lights in the sky were recorded on video by a man watching a football match near Seattle. Some witnesses believe that they were seeing a UFO, but the lights in the sky were later identified as a Russian rocket stage breaking up on reentry. 95% of such UFO sightings turned out to be reentering space debris. In Chile too, it was no UFO but another burning satellite reentering earth39。t been drinking that night and I had driven that same route at least a hundred times before. I now wonder if my family and I were abducted by the aliens and I just can39。t consider the human an intelligent being. Maybe they just stopped by to chat. Cautiously, I opened the car door. I stepped solidly onto the driveway, prepared to meet my fate. I looked around. Surprisingly, the yards had gone dark. I looked above me, but there was no sign of the object that had been there what seemed like only a moment ago. I ran into my house. It was quiet, dark. Normally my mother would call out to me, Is that you? But tonight I did not hear the familiar sound of her postdate questioning. I entered my parents39。t a house fire, as I had feared. It was a possibility I would have never anticipated, one that was perhaps even more fearsome than the house fire I had imagined. Hovering motionless only 50 feet above the rooftops was a strange object. Round and silvery, it was approximately 300400 feet in diameter. In the wake of the hovering enigma, there was an eerie silence. I stuck my head out
