听力原文：W: Excuse me, would you mind answering a few questions？

M: Well, I don't know. I am in rather a hurry actually.

W: It won't take a moment. We're doing a public opinion poll on some important political questions to try to find out if the Government really has support for its policies. The results are going to be published in a national newspaper.

M: Oh, all right, then.

W: Thanks. Well, I'll read out statements and you have to say whether you agree strongly, agree, disagree, disagree strongly or just don't know. OK？

M: Yes.

W: Well, first of all, "Policemen should always carry guns. " Do you agree？

M: No, not always.

W: What is your opinion？

M: They shouldn't do that when they're on normal duty. But if they're chasing a criminal who they know has got a gun, then they should be armed as well.

W: OK, next question. "Britain should drive on the right-hand side of the road. "

M: What rubbish! Why doesn't everybody else drive on the left？

W: All right. One more question: "Britain should leave the EEC. "

M: That's nasty. I wasn't in favor of us joining, but I think it would be difficult to leave now. I think we'll just have to stay in and make the best of it.

W: OK, that's all. Thank you very much.

W: Ahha. That's fine. What seems to be the problem？

M: Well, it's been nothing but trouble since I bought it.

W: OK. Just let me take a note of this. Err, radio-cassette player.

M: The first thing is one of the speakers doesn't work properly. The sound is completely distorted with the radio or a tape.

W: Which one is it？

M: The right-hand one. Another problem is the left cassette player. It chews up tapes. It's completely mined two of my favorite cassettes.

W: Oh dear. The speaker and the cassette player.

M: One of the cassettes was brand new, oh, and the rewind switch doesn't work. Actually it never did.

W: OK. So there's the fight-hand speaker...the cassette player and...urn, the rewind switch. Is that it？

M: No, I'm afraid not. The aerial doesn't work properly. It's stuck.

W: Hmm, I see what you mean. The handle is broken too.

M: Yes, I'd forgotten about that. It's not very good, is it？

A Future vehicle

What's the Moller Skycar？

While many technological advances occur in an evolutionary manner, occasionally a revolutionary technology appears on the horizon that creates startling new conditions and profound changes. Such is the case with the privately developed Moller Skycar, which is named after its inventor. With the inventor permission, I would like to discuss the military potential of this vehicle. The reinforced Moller Skycar variant the military is evaluating is called the light aerial multipurpose vehicle, or LAMV (pronounced "lam-vee").

The LAMV is a vertical take-off and landing aircraft that can fly in a quick, quiet, and agile manner. It is a new type of vehicle that combines the speed of an airplane and the vertical take-off capability of a helicopter with some characteristics of a ground vehicle, but without the limitations of any of those existing modes of transportation.

The LAMV is not operated like traditional fixed-or rotary-wing aircraft. It has only two hand-operators to direct the redundant computer control twists to select the desired operating altitude and moves fore and aft to select the rate of climb. The right-hand control twists to select the vehicle's direction and moves side-to-side to provide transverse (crosswise) movement during the hover and early-transition-to-flight phases of operation; it also moves fore and aft to control speed and braking. Simply put, the LAMV is user-friendly.

The LAMV of the future will be 18 feet long, 10 feet wide, and 6 feet high and weight 2,200 pounds. It will hold four passengers and a payload of 875 pounds (including fuel). The vehicle will have a maximum rate of climb of 6,400 feet per minute and an operational ceiling of 30,000 feet. It will attain a top speed of 390 miles per hour at an altitude of 6,000 feet and a cruising speed of 350 miles per hour at 25,000 feet, and it will have a maximum range of 900 miles at 80 passenger miles per gallon. The LAMV also will be quiet enough to function as an acoustic "stealth" plane at 500 feet. It will have a vertical take-off and landing capability and emergency airframe. parachutes, and it will be capable of using various fuels.

The LAMV features redundant, independent computer systems for flight management, stability, and control. Two airframe. parachutes can be deployed in the event of the vehicle's catastrophic failure. These parachutes ensure that the LAMV and the operator and soldiers it carries can land safely. The Wankel-type rotary engines are very reliable because of their simplicity. The three moving parts in a two-rotor Rotapower engines are approximately seven percent of the number of parts in a four-cylinder piston engine. Each engine room fully encloses the engines and fans, greatly reducing the possibility of injury to soldiers who might be near the vehicle in the event of an engine fire or explosion. Multiple systems check fuel for quality and quantity and provide appropriate warnings. The LAMV can land on virtually any solid surface.

The LAMV is aerodynamically stable. In the unlikely event that sufficient power is not available to land vertically, the LAMV's stability and good glide slope allow the operator to maneuver to a safe area before using the airframe. parachutes. Since computers control the LAMV's flight during hover and transition, the only operator input is to control speed and direction. Undesirable movements caused by wind gusts are prevented automatically.

The usage of LAMV in the future

The potential economic advantages of the LAMV are worth mentioning. Its fuel-efficient engines and ability to operate on various fuels will low fuel costs. The LAMV uses one-fourth of the fuel per passenger mile used by the tilt-rotor V-22 Osprey or high performance helicopters. The LAMV's acquisition cost also will be a significant factor in its favor.

The origins of etiquette—the conventional rules of behavior. and ceremonies observed in po

lite society—are complex. One of them is respect for authority. From the most primitive times, subjects(臣民) showed respect for their ruler by bowing, prostrating themselves on the ground, not speaking until spoken to, and never turning their backs to the throne. Some rulers developed rules to stress even further the respect due to them. The emperors of Byzantium expected their subjects to kiss their feet. When an ambassador from abroad was introduced, he had to touch the ground before the throne with his forehead. Meanwhile the throne itself was raised in the air so that, on looking up, the ambassador saw the ruler far above him, haughty and remote. Absolute rulers have, as a rule, made etiquette more complicated rather than simpler. The purpose is not only to make the ruler seem almost godlike, but also to protect him from familiarity, for without some such protection his life, lived inevitably in the public eye, would be intolerable. The court of Louis XIV of France provided an excellent example of a very highly developed system of etiquette. Because the king and his family were considered to belong to France, they were almost continually on show among their courtiers (朝臣). They woke, prayed, washed and dressed before crowds of courtiers. Even large crowds watched them eat their meals, and access to their palace was free to all their subjects. Yet this public life was organized so carefully, with such a refinement of ceremonial, that the authority of the King and the respect in which he was held grew steadily throughout his lifetime. A crowd watched him dress, but only the Duke who was his first valet de chamber (贴身男仆) was allowed to hold out the right sleeve of his shirt, only the Prince who was his Grand Chamberlain could relieve him of his dressing gown, and only the Master of the Wardrobe might help him pull up his trousers. These were not familiarities, nor merely duties, but highly desired privileges. Napoleon recognized the value of ceremony to a ruler. When he became Emperor, he discarded the revolutionary custom of calling everyone "citizen", restored much of the Court ceremonial that the Revolution had destroyed, and recalled members of the nobility to instruct his new court in the old formal manners. Rules of etiquette may prevent embarrassment and even serious disputes. The general rule of social precedence is that people of greater importance precede those of lesser importance. Before the rules of diplomatic precedence were worked out in the early sixteenth century, rival ambassadors often fought for the most honourable seating position at a ceremony. Before the principle was established that ambassadors of various countries should sign treaties in order of seniority, disputes arose as to who should sign first. The establishment of rules for such matters prevented uncertainty and disagreement, as to rules for less important occasions. For example, at an English wedding, the mother of the bridegroom should sit in the first pew or bench on the right-hand side of the church. The result is dignity and order. Outside palace circles, the main concern of etiquette has been to make harmonious the behaviour of equals, but sometimes social classes have used etiquette as a weapon against intruders, refining their manners in order to mark themselves off from the lower classes. In sixteenth-century Italy and eighteenth-century France, decreasing prosperity and increasing social unrest led the ruling families to try to preserve their superiority by withdrawing from the lower and middle classes behind barriers of etiquette. In a prosperous community, on the other hand, polite society soon absorbs the newly rich, and in England there has never been any shortage of books on etiquette for teaching them the manners appropriate to their new way of life. Every code of etiquette has contained three elements: basic moral duties; practical rules which promote efficiency; and artificial, optional graces such as formal compliments to, say, women on their beauty or superiors on their generosity and importance. In the first category are consideration for the weak and respect for age. Among the ancient Egyptians the young always stood in the presence of older people. Among the Mponguwe of Tanzania, the young men bow as they pass the huts of the elders. In England, until about a century ago, young children did not sit in their parents&39; presence without asking permission. Practical rules are helpful in such ordinary occurrences of social life as making proper introductions at parties or other functions so that people can be brought to know each other. Before the invention of the fork, etiquette directed that the fingers should be kept as clean as possible; before the handkerchief came into common use, etiquette suggested that, after spitting, a person should rub the spit inconspicuously (难以察觉的) underfoot. Extremely refined behavior, however, cultivated as an art of gracious living, has been characteristic only of societies with wealth and leisure, which admitted women as the social equals of men. After the fall of Rome, the first European society to regulate behavior. in private life in accordance with a complicated code of etiquette was twelfth-century Provence, in France. Provence had become wealthy. The lords had returned to their castles from the crusades (十字军东征) , and there the ideals of chivalry (武士制度) grew up, which emphasized the virtue and gentleness of women and demanded that a knight (骑士) should profess a pure and dedicated love to a lady who would be his inspiration, and to whom he would dedicate his brave deeds, though he would never come physically close to her. This was the introduction of the concept of romantic love, which was to influence literature for many hundreds of years and which still lives on in a belittled form. in simple popular songs and cheap novels today. In Renaissance Italy too, in the fourteenth and fifteenth centuries, a wealthy and leisured society developed an extremely complex code of manners, but the rules of behavior. of fashionable society had little influence on the daily life of the lower classes. Indeed many of the rules, such as how to enter a banquet room, or how to use a sword or handkerchief for ceremonial purposes, were irrelevant to the way of life of the average working man, who spent most of his life outdoors or in his own poor hut and most probably did not have a handkerchief, certainly not a sword, to his name. Yet the essential basis of all good manners does not vary. Consideration for the old and weak and the avoidance of harming or giving unnecessary offence to others is a feature of all societies everywhere and at all levels from the highest to the lowest. You can easily think of dozens of examples of customs and habits in your own daily life which come under this heading. Etiquette simply serves the purpose of showing respect for authority.
