.Unit 6 in book 4Part One Listening,Understanding and SpeakingListening 1Ex 1: 3,5,6,8,10Ex 2: four, 6.9, 5.1, doubly, far moreScripts: Husband: Oh! Its unbelievable! Wife: Whats the matter? Husband: The article says that lifespan varies according to race, income level and whether you are male or female. Now, can you guess which is the most important factor? Wife: Hmm, I think it might be the sex. Husband: Thats right! My grandma lived four years longer than my grandpa. Generally speaking, women live longer than men. In 1993, the average lifespan of women was 6.9 years longer than that of men in the United States. Wife: 6.9 years! I cant believe it. Then how about race? Husband: About race, the paper says white women live 5.1 years longer than black women. Wife: So this means I am doubly lucky since Im a white woman. Husband: Yes. But actually the largest risk you could run is being poor. Being poor is far more likely to kill you than smoking, drinking, a hereditary disease, or an unhealthy lifestyle. Wife: Thats true. If you are poor, you may not have good living conditions, good medical care and good nutrition. But still I have a question. Why do women live longer than men? Husband: I think youd better ask the experts.Listening 2Ex 1: FTFTTEx 2: 1.bad, degree, opportunity 2.relate, measure these risks 3.mathematics, occur 4.information, statistical risk 5.pollution, smoking, fiberScripts: The possibility that something bad will happen is a risk. Risk can also be defined as the degree of danger that goes along with an opportunity. All risks have possible negative results. However, some risks are worth taking. For example, suppose that you have the chance to join a school football team. You risk a possible injury while playing to achieve the sense of accomplishment that comes with being on the team. You decide that the pleasure of playing is worth the risk of injury. By being fit, you can also reduce the risk of physical injury. How can we determine the risks involved in an action? Many risks that relate to health choices have been studied. These risks relate to choices made over activities or behaviour that influence ones health, either positively or negatively. Scientists can use statistics to measure these risks. Statistics is a branch of mathematics that helps determine the possibility that something will occur. The information about this possibility is called statistical risk and can help you make healthy choices. For example, statistics indicate that in the United States the chance of dying from cancer is about 20 percent. In other words, two out of every 10 deaths are due to some kind of cancer. Therefore, the risk of death from cancer is quite high. However, statistics also show that 80 percent of all cancers are related to things over which you have some control. In other words, you can make choices that will reduce your risk of developing cancer. These include such things as avoiding pollution, mot smoking and eating a diet high in fiber. If you do these things, you are less likely to develop cancer.Listening 3Ex 1: AHCLE GINJF KMOBDEx 2: BDDDDScripts: If you plan to go hiking in the wilderness or a national park, make sure you are prepared. A compass, a knife, and maps are essential items to take with you. You should also take wooden matches in a waterproof case; some concentrated food such as nuts and dried fruit and water in a canteen. Plan for emergencies as well. Take along first-aid equipment, shelter for the rain, and extra clothes. In order to stay warm, your head, hands and feet must be kept warm, so you should bring gloves, extra socks and a wool hat. If you get lost in the woods, first try to backtrack and find the trail you were on. Look for trail signs other people may have left, such as piles of rocks, tied bunches of grass, or broken branches. Sit down and try to figure out which direction you came from and then go back that way.  If you can't find the trail, try to explore the area, marking your path as you go. Climb a tree and look for landmarks. During the day, look for roads or rooftops in the distance. At night, look for lights and sniff the air. You may be able to smell smoke from a campfire. If you detect any of these signs, start to walk in their direction, but if it is dark, find shelter for the night and wait until the morning. Even a full moon won't give you enough light to see; it can throw shadows that hide dangers. If you are lost, do not expect to be rescued. Even if someone knows you are lost and sends out a search party, it may not find you. Therefore, if you can get out on your own, do so. However, if you cannot move far for some reason, build a bright fire at night and a smoky one during the day. Try to clear an area that can be seen from the air, and use rocks to write a message. You can also use bright colors, shiny metal or mirrors to signal aircraft. Above all, do not panic.

Over in Bolivia, for example, I was working for a small airline, and we carried just about everything: animals, whisky, dynamite, and, of course, people. There were times when I felt I was flying a bomb, not a plane. Once I was taking dynamite to the mines. Dynamite! Man, I had never seen so much. They had even put some on the floor right next to me. I was certainly nervous on that trip. Well, I was flying over the mountains when suddenly the engine stopped. Somehow I got my parachute on, and got down without the plane, but I was hurt. I was lying out there for about four days before they found me. They told me later that they had almost given me up for dead. Anyway, they got me back to the hospital, and three months later I was flying again. No, I'm not afraid of flying. But there's a lot to worry about as a pilot.Part Four Further Speaking and ListeningFurther ListeningListening 1Ex 1: F T T T F Ex 2: 1. 17，Mallett Street, Alford 2. 3. fire service 4. 18 5. 16, 20 Scripts:Balley: Hello, fire service.Grace:Oh, em, I'm ringing because I think there's a fire in the house across the street.

Nobody knew how much air was inside and what the situation was for the trapped miners. Rescue teams tried every way to get some message from the miners, but it all seemed in vain. This caused worldwide concerns. The accident was reported by the world media. But this morning, to people's great surprise, came the dramatic news that rescue teams had dug 60 meters and tunneled through. They had discovered survivors in the part of the mine not flooded. For the rest of the miners, however, those were really anxious moments. They had prepared themselves for the worst. Now suddenly there was hope that they could see their loved ones again. And then they too were rescued and brought out of the mine. Exhausted and wounded, they were not strong enough to wave to their relatives or friends. Wrapped with blankets, these survivors were carefully handed over to the ambulances and taken to a nearby hospital. However, not everyone survived. One miner was reported to have been found dead, another missing.

I suppose that's right.Reporter:When was your worst accident?Joe:I'd say last year. It was during the British Grand Prix. I smashed into a wall. The car was completely ruined and my left leg was broken. Luckily, nobody was killed.Reporter:Is that the only time you've been close to death?Joe: No. Once, during the Mexican Grand Prix, two cars in front of me had a bad accident. One of them ran into the other. I swerved to avoid them and hit a fence. My car was badly damaged, but luckily, I wasn't even hurt.Reporter: You must enjoy danger. I mean, you wouldn't be a racing-driver otherwise?Joe:I don't know about that. I had a very frightening experience quite recently. I was frightened to death! I thought I was going to be killed at any moment.Reporter:Really? Was that during your last race?Joe:No. It was on my way to this studio. I had to drive through London during rush hour.Listening 4Ex 1: TFTFFFFFEx 2: 1. New York 2. luxury liners 3. heroism 4. evil 5. “unsinkable” 6. July 26,1956 7. 1 8. 101 9. Iceberg 10. Yes 11. 1500 12. 60 13, half 14. More than enough 15. another ship Scripts: On the morning of April 10, 1912, the luxury liner,Titanic, left England on a voyage to New York. Four days later, she lay at the bottom of the Atlantic Ocean. On July 18, 1956, the ocean liner, Andrea Doria, left Italy. It was also traveling to New York. Eight days later, this great ship also lay at the bottom of the Atlantic. The sinking of the two huge ships shocked the world. Reports of the two tragedies filled the newspapers for days. When Andrea Doria went down, people compared her sinking with the sinking of Titanic. There were similarities between the two events; however, there were also important differences. What were some of these similarities? First of all, both ships were transatlantic ocean liners. In addition, they were both luxury liners. They carried many of the world's rich and famous people. In fact, 10 American millionaires lost their lives when Titanic went down. Today, millions of dollars worth of gold, silver, and cash may still remain locked inside these two sunken ships. Another similarity is that as each ship was sinking, there were acts of heroism and of evil. Some people acted very bravely, even heroically. Some people even gave up their lives so that others could live. There were also some people who acted like cowards. For example, one man on Titanic dressed up as a woman so that he could get into a lifeboat and save his own life. One last similarity is that both of these ships were considered "unsinkable". People believed that they would never sink. There are also differences between these great ship disasters. To begin with, Titanic was on her very first voyage across the Atlantic; Andrea Doria, on the other hand, was on her hundred and first transatlantic crossing. Another difference is that the ships sank for different reasons. Titanic struck an iceberg; while Andrea Doria collided with another ship. Also, Andrea Doria had radar to warn of the approach of another ship; but Titanic was not equipped with radar-It had only a lookout. The lookout was only able to see the iceberg moments before the ship struck it. But, of course, the greatest difference between these two terrible accidents is the number of lives lost. When Titanic sank, more than 1,500 people died-They drowned or froze to death in the icy North Atlantic water. Also, about 700 people survived the sinking. In the Andrea Doria accident, 60 people lost their lives, and around 1,650 lives were saved. One of the reasons that so many people died on Titanic is that the ship was considered to be unsinkable, so there were about half the number of necessary lifeboats to rescue all the people aboard. Andrea Doria had more than enough lifeboats to rescue every person on the ship. However, they were only able to use about half of the lifeboats due to a mechanical problem. The passengers and crew of Andrea Doria were very lucky that another ship was able to rescue most of them. The passengers on Titanic were not so fortunate. It is interesting too that the wreck of Titanic was only found in September, 1985.
