【正文】 n I attempted to awaken my two brothers. I had to shake them too to get a response. Neither brother had seen a thing. They both told me to go to bed. Incredulous, I decided to follow my family39。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。t explain what I saw. I hadn39。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 remember it. Why would the craft have been there? What purpose could it have had hovering so close to the houses of my neighborhood? I hope to one day undergo a hypnotic treatment to find some answers. Thirtythree years after my experience, I am still left with the nagging question of what really happened that cold fall night. Questions: 1. What decision did the narrator make in the presence of a possible danger? 2. What was one possible purpose of the aliens39。 visit to the family according to the narrator? 3. How many people were there in the narrator39。s family? 4. What happened when the narrator decided to approach the flying saucer? 5. Why didn39。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。s atmosphere. And the shower of molten metal was not just aluminum: the Spacecraft was carrying a payload of plutonium. Mars 96 had been an interplaary probe launched from Kazakhstan. The plutonium provided energy to keep its instruments warm as it traveled into deepest space. The final stage was supposed to push the probe on its path to Mars. But it failed and the rocket was stuck in lowearth orbit. It was only a matter of time before it would be dragged back by gravity. As Mars 96 descended over Australia it managed to plete another half orbit around the earth and, and according to the Russians, landed in the Pacific. Or did it? Questions: 1. What were those lights traveling across the sky? 2. What were those objects that acpanied the descent of these lights? 3. What was the purpose of using plutonium on Mars 96? 4. What was the fate of Mars 96? UNIT 5 Laughter: The Best Medicine The following is an interview by a TV hostess with Dr. Lee Berk of the Loma Linda School of Public Health in California. W: We39。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 the perfect workout for anyone who doesn39。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。s called the Smile TimeOut. W: How does it work? M: 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。t in a mood to laugh? M: OK, remember, even when you fake a smile or laugh, you get the same physiological benefits as when it39。s the real thing, because your mind is smart, but your body is stupid and can39。t tell the difference! W: Great! Ha, ha, ha ...! I39。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
