Although I know that many of you think the opposite, most human beings have a high level of intelligence, a good memory and can solve problems easily. They live longer and therefore tend to be much more aware of past and future than we are. They communicate by a set of sounds which carry meaning from the order in which they are placed, and which vary from territory to territory, so that some humans find difficulty in communicating with others according to where they come from--if they have been raised in different country and have not had special training. Humans have also invented a set of marks on paper which they use to represent these sounds and which you may often see them concentrating on. In these two ways they have developed their eyes and ears to a higher level of interpretation than ourselves, but in doing so they have lost the ability to gather much of the information which we continually do both from these and our other senses. Most dogs are able to interpret at least part of the vocabulary (voice meanings) of humans, and some of us have learned to recognize some of the pattern of marks which they use to record them on paper so that humans at a different time and in a different place can understand their messages, but it would put our other abilities into danger if we ourselves developed these skills very far. Fortunately, most humans are able to understand a similar amount of our communicatory sounds and behaviour. Try going up to a human, sitting down in front of him and raising a front paw in a gesture. He will almost certainly take it and give it a shake, because it is a greeting gesture for humans, too. He will think you are behaving like a human--and nothing seems to please humans more. Careful, there is a danger here! You are not a human. You are a dog--and if you are going to be happy you should never forget it. You need to live as a dog. It is all very well changing yourself slightly-to fit in with a human pack, but if you deny your true nature you are going to end up a mad dog and, humans will think, a bad dog. There is always a reason for any animal choosing to live with an animal of a different sort, but all too often we have no choice. We have to live with humans. But humans have consciously decided that they want us with them, although not necessarily for the reason that they believe. They may want you as a watchdog to keep burglars away. They may have some idea that looking after you will teach their pups a sense of responsibility. Or they may simply be in desperate need of companionship, of something to love. Whom do you think the passage is really written for

Not every President is a leader, but every time we elect a President we hope for one, especially in times of doubt and crisis. In easy times we are ambivalent -- the leader, after all, makes demands, challenges the status quo, shakes things up.Leadership is as much a question of timing as anything else.(67) And when he comes, he must offer a simple, eloquent message.Great leaders are almost always great simplifiers, who cut through argument, debate and doubt to offer a solution everybody can understand and remember. Churchill warned the British to expect "blood, toil, tears and sweat"; FDR told Americans that "the only thing we have to fear is fear itself"; Lenin promised the war-weary Russians peace, land and bread. Straightforward but potent messages.We have an image of what a leader ought to be. We even recognize the physical signs: Leaders may not necessarily be tall, but they must have bigger-than-life, commanding features--LBJ’s nose and ear lobes, Ike’s broad grin. A trademark also comes in handy: Lincoln’s stovepipe hat, JFK’s rocker. We expect our leaders to stand out a little, not to be like ordinary men. Half of President Ford’s trouble lay in the fact that, if you closed your eyes for a moment, you couldn’t remember his face, figure or clothes. A leader should have an unforgettable identity, instantly and permanently fixed in people’s minds.It also helps for a leader to be able to do something most of us can’ t: FDR overcame polio; Mao swam the Yangtze River at the age of 72. We don’t want our leaders to be "just like us". We want them to be like us but better, special, more so.(68) Even television, which comes in for a lot of knocks as an image-builder that magnifies form over substance, doesn’t altogether obscure the qualities of leadership we recognize, or their absence. Television exposed Nixon’s insecurity, Humphrey’s fatal infatuation with his own voice.A leader must know how to use power, but he also has to have a way of showing that he does. He has to be able to project firmness-- no physical clumsiness(like Ford., no rapid eye movements(like Carter).A Chinese philosopher once remarked that a leader must have the grace of a good dancer, and there is a great deal of wisdom to this.(69) He should be able, like Lincoln, FDR, Truman, Ike and JFK, to give a good, hearty, belly laugh, instead of the sickly grin that passes for good humor in Nixon or Carter. Ronald Reagan’s training as an actor showed to good effect in the debate with Carter, when by his easy manner and apparent affability, he managed to convey the impression that in fact he was the President and Carter the challenger.If we know what we’ re looking for, why is it so difficult to find The answer lies in a very simple truth about leadership. People can only be led where they want to go. The leader follows, though a step ahead.(70) The British believed that they could still win the war after the defeats of 1940, and Churchill told them they were right.A leader rides the waves, moves with the tides, understands the deepest yearnings of his people. He cannot make a nation that wants peace at any price go to war, or stop a nation determined to fight from doing so. His purpose must match the national mood. His task is to focus the people’s energies and desires, to define them in simple terms, to inspire, and make what people already want seem attainable, important, within their grasp.(71) Winston Churchill managed, by sheer rhetoric, to turn the British defeat and the evacuation of Dunkirk in 1940 into a major victory. FDR’s words turned the sinking of the American fleet at Pearl Harbor into a national rallying cry instead of a humiliating national scandal. A leader must stir our blood, not appeal to our reason...A great leader must have a certain irrational quality, a stubborn refusal to face facts, infectious optimism, the ability to convince us that all is not lost even when we’re afraid it is. Confucius suggested that, while the advisers of a great leader should be as cold as ice, the leader himself should have fire, a spark of divine madness.A. Yet if they are too different, we reject them. Adlai Stevenson was too cerebral. Nelson Rockefeller, too rich.B. The leader must appear on the scene at a moment when people are looking for leadership, as Churchill did in 1940, as Roosevelt did in 1933, as Lenin did in 1917.C. Americans wanted to climb out of the Depression and needed someone to tell them they could do it, and FDR did.D. Our strength makes him strong; our determination makes him determined; our courage makes him a hero. He is the symbol of the best in us.E. Above all, he must dignify our desires, convince us that we are taking part in the making of great history, give us a sense of glory about ourselves.F. A leader should know how to appear relaxed and confident. His walk should be firm and purposeful. 71().

To me personally, the most remarkable and, in the long run, the most influential man who was translated was not a Greek. That is because I am interested in the perception of objects in space. And that was a subject about which the Greeks were totally wrong. It was understood for the first time about the year AD 1000 by an eccentric mathematician whom we call Alhazen, who was the one really original scientific mind that Arab culture produced. (66) Alhazen first recognized that we see an object because each point of it directs and reflects a ray into the eye. The Greek view could not explain how an object, my hand say, seems to change size when it moves. In Alhazen’s account it is clear that the cone of rays that comes from the outline and shape of my hand grows narrower as I move my hand away from you. (67) And that, and only that, accounts for the difference in size. It is so simple a notion that it is astonishing that scientists paid almost no attention to it for six hundred years. (68) The concept of the cone of rays from object to the eye becomes the foundation of perspective [透视画法]. And perspective is the new idea which now revivifies mathematics. (69) A manuscript of Alhazen’s Optics in translation in the Vatican Library in Rome is annotated by Lorenzo Ghiberti, who made the famous bronze perspectives for the doors of the Baptistry in Florence. He was not the first pioneer of perspective--that may have been Filippo Brunelleschi--and there were enough of them to form an identifiable school of the Perspectivi. (70) A. It was a school of thought, for its aim was not simply to make the figures lifelike, but to create the sense of their movement in space.B. The Greeks had thought that light goes from the eyes to the object.C. The excitement of perspective passed into art in north Italy, in Florence and Venice, in the fifteenth century.D. As I move it towards you, the cone of rays that enters our eye becomes larger and subtends a larger angle.E. Above all, we feel that the painter’s eye is on the move.F. But artists attended to it long before that, and in a practical way.
Audi A3 Most of our drivers said the A3 was their definite favourite in this group. They described it as refined and comfortable with good handing characteristics and light, precise steering. All the seats were comfortable and the front ones were easy to adjust. Most drivers liked the driving position, helped by a good range of steering wheel and seat height adjustments. The main instruments were clear and dashboard controls were well positioned. Mirror coverage was excellent but our drivers complained that the view out of the rear was badly hindered by the high rear window line and thick pillars. Getting into the back seats was easy, thanks to a clever seat mechanism, which moves the seat up and forward as well as tilting the backrest. Rear legroom was reasonable but the rear seat was only barely wide enough for three adults. Luggage space was average for this class of car but you have to remove the rear head restraints to fold the rear seat. There were plenty of useful interior storage spaces. All A3s come with an alarm and immobilizer as standard. Our "thief" got in through the doors in 20 seconds. But the radio was a non-standard fit, which is probably to deter thieves. The hinges of the rear seats could release in an accident, allowing luggage to crash through into the passenger compartment. Also, the driver’s knees could be damaged by stiff structures under the dash. Some parts of the fuel system and electrics would be vulnerable to damage in a frontal collision. Honda Civic Honda says its special VTEC engine has a winning combination of economy and performance, but our drivers found it a bit of a curate’s egg. It was the most economical of the car on test, but drivers found it sluggish at low revs, and its acceleration in the fifth gear was slow, so overtaking normally meant having to shift down to the fourth gear. The driving position was acceptable, but our panel criticized the restricted rear visibility— the rear window was quite small. Drivers found the back rest supportive but it was not available to make fine adjustments to the angle. The ride comfort was acceptable, but it wasn’t as good as the Audi’s or Rover’s. The driver’s seat didn’t slide forward when it was tilted, making rear access awkwardly from this side. In the back, headroom and legroom was excellent but testers didn’t find the seats particularly comfortable. The luggage space was small for this class of car, especially with the rear seats in place. However, folding the rear seat to increase luggage space was easy. Other points proved by our panel included well-placed minor controls, good mirror coverage, but fiddly radio controls. All Civics come with an immobilizer but no alarm. You may want to consider paying extra for an alarm, as our "thief" broke into through the doors in 13 seconds, and into the engine bay in just five seconds. There were stiff structures under the dash which could damage the driver’s knees in an accident, though there was no problem on the passenger’s side. The handbook (like the Audi’s) provided suggestion on Using child restraints. Rover 216 The 1.6-litre engine had good power delivery at both high and low revs but some drivers complained that it was noisy at high revs. The brakes didn’t have very good progression, but drivers like their positive feel. Ride comfort and the handling were recommended. But drivers found it difficult to achieve a comfortable driving position, The driver’s seat was not height-adjustable, and there was only limited space to rest your clutch foot. Some testers also found the seat backrest uncomfortable. Visibility was married by the small mirrors. The rear view was also restricted by thick pillars and the small rear window, Getting into the back was tricky because the front seats did not slide forward when tilted. Once in the back, legroom and headroom were poor, and testers complained that their rear seat base was unsupportive. Luggage space was smaller than average for this class of car—this was compounded by a high boot sill and difficulties in folding the rear seat. But there were large pockets in the doors and rear side panels. The main radio controls were more convenient; they were mounted on the steering wheel so drivers didn’t have to take their hands off the wheel to use them. Our Rover 200s came with an alarm, though this isn’t standard on all versions. Our "thief" broke in through the doors in 15 seconds. Some of the electrics would be vulnerable in a frontal impact. The rear seat hinges could release in an accident, allowing luggage to crash through into the passenger compartment. Also, information in the handbook on using child restrains was not adequate. ·offers a poor view even when the mirrors are used
