FireA gift of the gods. According to an old Greek myth, Prometheus and his brother, Epimetheus, heroes of a race of giants called the Titans, were given the task of creating man. Epimetheus was also to provide all the animals with means of defense or flight. To some he gave courage, strength, and claws with which to fight, and to others long legs, nimble feet, or wings with which to escape. So lavish (慷慨的) was he with these gifts to the lower animals that he had nothing left to give to man. Prometheus, however, was determined that man should not be neglected and so, according to the myth, he gained access to heaven and lighted his torch at the chariot of the sun. Returning to earth, he presented fire to man, and with this gift came man's dominion over all the earth.The first cook. It took a long time, however, to learn how to use this gift. For centuries men lived like wild animals. Their food consisted of nuts, herbs, fruit, and the flesh of animals. Cooking was unknown, and when a wild animal was captured, the savage tore it apart and ate the raw flesh. According to one legend, a hunter, after a long tramp, succeeded in catching a rabbit. On his way home he found a smoldering (缓慢燃烧的) fire which had been started by lightning. Throwing his rabbit on a log, he lay down and went to sleep. When he awoke, he found that his rabbit had fallen into the fire. In attempting to rescue it, the savage got some of the juice of the roasted rabbit on his fingers. By instinct, he put his burnt fingers to his mouth, and the taste was so pleasing that he immediately finished the rabbit, and this is how man learned to cook.Reduction of metals. Ages later, man began to use fire to make metals and to form them into spears and hatchets for hunting and fighting. The alchemists, as we know, used fire in their attempts to change the base metals into gold, and today fires are burning in many furnaces producing, if not gold, metals of far greater value to the progress of civilization. Copper, bronze, iron, and steel, produced by fire, have been the stepping stones of man's progress through the ages. The chemistry involved in the extraction, purification, and alloying of metals is so interesting and of such great importance that volumes have been written on this subject.Heating homes. We are so accustomed to living in heated homes that it is only when something goes wrong with the furnace that we give any thought to the blessed fire. To the savage shivering in his cave, however, a fire was a real blessing, even if it did fill his eyes with smoke. Keeping the home fires burning was a difficult task for the American Indian, who delegated this to his wife. Woe be to the squaw(印第安女子或妻子) who let the fire go out. In the wintertime, the fire was built on the ground in the center of the tent, which had a small hole in the top to act as a smokestack. Even the palaces of the wealthy in the Middle Ages were cold and damp, the fireplaces being so inefficient that only a portion of one room could be heated at a time. Not until a comparatively recent date (1742) were stoves invented, and furnaces were unknown even when yourgrandfather was a boy.How fires are started and stopped. You have learned that burning is rapid oxidation which gives off light and heat. In order to start a fire, three conditions are necessary: (1) something to burn; (2) something to support the combustion; and (3) a means of lighting the fuel (raising it to its kindling temperature). Having lived all his life in a home where the furnace is kept burning all winter, the average person seldom thinks of the difficulty of starting a fire.To get some idea of the difficulty of starting fires, imagine yourself shipwrecked like Robinson Crusoe upon an uninhabited island. To build a fire, the first condition would be met by collecting some wood. The second condition would be no problem as air is always present to support combustion. The third condition, raising the fuel to its kindling temperature, would offer a real difficulty. Two methods have been used. The first is to employ the heat of friction caused by rubbing two dry sticks together. This sounds simple, but much skill and practice are essential to the success of this operation. The second method is to make sparks by striking two pieces of flint (极硬的东西, 燧石) together. This may work if the operator is persistent and if his fuel is sufficiently fine and dry. But before he succeeds in getting a fire started by either method, our Robinson Crusoe will do some thinking about the usefulness of the common match.Poison matches. There are two kinds of phosphorus used in making matches, white and red. White phosphorus has an advantage and a disadvantage. White phosphorus is cheaper and, at one time, its use was quite common. White phosphorus is poisonous, however, and for this reason its use in making matches is prohibited by law in nearly all civilized countries. Men working in match factories which used white phosphorus were subject to a disease which caused the jaw bones to decay. The danger of small children being poisoned by these matches is also evident.Fortunately, chemists have discovered a method of making a form of phosphorus which is not poisonous. When white phosphorus is gently heated for several hours in a closed vessel from which air is excluded, it slowly changes in color and the no-poisonous red phosphorus is formed. In addition to the fact that it is not poisonous, red phosphorus has other advantages. Its kindling temperature is much higher than that of the white variety, and this makes red phosphorus less dangerous to ship and to store. Another method of making phosphorus safe for use in matches is to combine it with sulphur. To do this, the two elements are mixed and heated in the absence of air. The phosphorus sulphide, which is formed, is not poisonous.1. With the help of his brother, Prometheus succeeded in presenting fire to man.2. Fire gave man an advantage over other animals.3. Man learned to cook by accident.4. In the Middle Ages even the palaces of the wealthy were cold because wood was much too expensive.5. In striking a match, friction raises the phosphorus compound in the tip to the kindling temperature.6. Red phosphorus is the only means of making phosphorus safe.7.

We have probably all had lectures pointing out that laziness is immoral, that it is wasteful, and that lazy people will never amount to anything in life. But laziness can be more harmful than that, and it is often caused by more complex reasons rather than simple wish to avoid work. Some people who appear to be lazy are suffering from much more serious problems. They may be so distrustful of their fellow workers that they are unable to join in any group task for fear of ridicule or of having their idea stolen. These people who seem lazy may be ruined by a fear of failure that prevents fruitful work. Or other sorts of fantasies (幻想) may prevent work; some people are so busy planning, sometimes planning great deals of fantastic achievements that they are unable to deal with whatever "lesser" work is on hand. Still other people are not avoiding work; strictly speaking, they are merely procrastinating rescheduling their day.Laziness can actually be helpful. Like procrastinators, some people may look lazy when they are really thinking, planning, researching. We should all remember that great scientific discoveries occurred by chance. Newton wasn't working in the orchard when the apple hit him and he devised the theory of gravity. All of us would like to have someone "lazy" build the car or stove we buy, particularly if that "laziness" were caused by the worker's taking time to check each step of his work and to do his job right. And sometimes, being"lazy"—that is,, taking time off for a rest—is good for the overworked students or executives. Taking a rest can be particularly helpful to the athlete who is trying too hard or the doctor who's simply working himself overtime too many evenings at the clinic. So be careful when you're tempted to call someone lazy. That person may be thinking, resting, or planning his or her next work.1.

The brain is like a telephone exchange. It is the switchboard, but not the whole system. Its function is to receive incoming signals, make proper connection, and send the messages through to their destination. For efficient service, the body must function as a whole.But where is the "mind"? Is it in the brain? Or perhaps in the nervous system? After all, can we say that the mind is in any particular place? It is not a thing, like a leg, or even the brain. It is a function, an activity. Aristotle, twenty-three hundred years ago, observed that the mind was to the body what cutting was to the ax. When the ax is not in use, there is no cutting. So with the mind. "Mind,"said Charles H. Woolbert, "is what the body is doing. "If this activity is necessary for thinking, it is also necessary for carrying thought from one person to another. Observe how people go about the business of ordinary conversation. If you have never done this painstakingly, you have a surprise in store, for good conversationalists are almost constantly in motion. Their heads are continually nodding and shaking sometimes so vigorously that you wonder how their necks can stand the strain.Even the legs and feet are active. As for the hands and arms, they are seldom still for more than a few seconds at a time.These people, remember, are not making speeches. They are merely common folk trying to make others understand what they have in mind. They are not conscious of movement. Their speech is not studied. They are just human creatures in a human environment, trying to adapt themselves to a social situation. Yet they converse, not only with oral language, but with visible actions that involve practically every muscle in the body.In short, because people really think all over, a speaker must talk all over if he succeeds in making people think.1.
