单选题So far as I know, Miss Hannah Arendt was the first person to define the essential difference between work and labor. To be happy, a man must feel, firstly, free and, secondly, important. He cannot be really happy if he is compelled by society to do what he does not enjoy doing, or if what he enjoys doing is ignored by society as of no value or importance. In a society where slavery in the strict sense has been abolished, the sign that what a man does is of social value is that he is paid money to do it, but a laborer today can rightly be called a wage slave. A man is a laborer if the job society offers him is of no interest to himself but he is compelled to take it by the necessity of earning a living and supporting his family. The antithesis to labor is play. When we play a game, we enjoy what we are doing, otherwise we should not play it, but it is a purely private activity; society could not care less whether we play it or not. Between labor and play stands work. A man is a worker if he is personally interested in the job which society pays him to do; what from the point of view of society is necessary labor is from his own point of view voluntary play. Whether a job is to be classified as labor or work depends, not on the job itself, but on the tastes of the individual who undertakes it. The difference does not, for example, coincide with the difference between a manual and a mental job; a gardener or cobbler may be a worker, a bank clerk, a laborer. Which a man is can be seen from his attitude toward leisure. To a worker, leisure means simply the hours he needs to relax and rest in order to work efficiently. He is therefore more likely to take too little leisure than too much; workers die of coronaries and forget their wives' birthdays. To the laborer, on the other hand, leisure means freedom from compulsion, so that it is natural for him to imagine the fewer hours he has to spend laboring, and the more hours he is free to play, the better.

单选题{{B}}Passage Four{{/B}} I still remember--my hands and my fingertips still remember--what used to lie in store for us on our return to school from the holidays. The trees in the school yard would be in full leaf again and the old leaves would be lying around in scattered heaps like a muddy sea of leaves. "Get that all swept up!" the headmaster would tell us. "I want the whole place cleaned up, at once!" There was enough work there, to last for over a week. Especially since the only tools with which we were provided were our hands, our fingers, our nails. "Now see that it's done properly, and be quick about it," the headmaster would say to the older pupils, "or you'll have to answer for it!" So at an order from the older boys we would all line up like peasants about to cut and gather in crops. If the work was not going as quickly as the headmaster expected, the big boys, instead of giving us a helping hand, used to find it simpler to whip us with branches pulled from the trees. In order to avoid these blows, we used to bribe our tyrants with the juicy cakes we used to bring for our midday meal. And if we happened to have any money on us the coins changed hands at once. If we did not do this, if we were afraid of going home with an empty stomach or an empty purse, the blows were redoubled. They hit us so violently and with such devilish enjoyment that even a deaf and dumb person would have realized that we were being flogged not so much to make us work harder, but rather to beat us into a state of obedience in which we would be only too glad to give up our food and money. Occasionally one of us, worn out by such calculated cruelty, would have the courage to complain to the headmaster. He would of course be very angry, but the punishment he gave the older boys was always very small--nothing compared to what they had done to us. And the fact is that however much we complained our situation did not improve in the slightest. Perthaps we should have let our parents know what was going on, but somehow we never dreamed of doing so; I don't know whether it was loyalty or pride that kept us silent, but I can see now that we were foolish to keep quiet about it, for such beatings were completely foreign to our nature.

单选题For years pediaticians didn"t worry much about treating hypertension in their patients. After all, kids grow so fast, it"s hard keeping up with their shoe size, let alone their blood pressure. Sure, hypertension in adults places them at greater risk of heart attack and stroke. But nobody likes the idea of starting youngsters on blood-pressure medicine they could wind up taking the rest of their lives. Who knows what previously unheard-of side effects could crop up after five pr six decades of daily use? The rationale has been: kids grow out of so many things, maybe they"ll grow out of this too. Now, though, comes word that high blood pressure can be destructive even in childhood. According to a recent report in the journal Circulation, 19 of 130 children with high blood pressure developed a dangerous thickening of the heart muscle that, in adults at least, has been linked to heart failure. "No one knows if this pattern holds true for younger patients as well," says Dr. Stephen Daniels, a pediatric cardiologist who led the study at Children"s Hospital Medical Center in Cincinnati, Ohio. "But it"s worrisome. " Who"s most at risk? Boys more than girls, especially boys who are overweight. Their heart works so hard to force blood through extra layers of fat that its walls grow more dense. Then, after decades of straining, it grows too big to pump blood very well. Fortunately the abnormal, thickening can be spotted by ultrasound. And in most case, getting that blood pressure under control—through weight loss and exercise or, as a last resort, drug treatment—allows the overworked muscle to shrink to normal size. How can you tell if yours are like the 670,000 American children ages 10 to 18 with high blood pressure? It"s not the sort of thing you can catch by putting your child"s arm in a cuff at the free monitoring station in your local grocery. You should have a test done by a doctor, who will consult special tables that indicate me normal range of blood pressure for a particular child"s age, height and sex. If the doctor finds an abnormal result he will repeat the test over a period of months to make sure the reading isn"t a fake. He"ll also check, whether other conditions, like kidney disease, could be the source of the trouble. Because hypertension can be hard to detect the National Heart, Lung and Blood Institute recommends annual blood-pressure checks for every child over age 3. About ha! the cases of hypertension stem directly from kids being overweight. And the problem is likely to grow. Over the past 30 years the proportion of children in the U. S. who are overweight has doubled, from 5% to 11 to or 4.7 million kids. You can keep your children from joining their ranks by clearing the junk food from your pantry and hooking you kids—the earlier the better—on healthy, attractive snacks like fruits(try freezing grapes or carrot sticks with salsa). Not only will they lower your children"s blood pressure: these foods will also boost their immune system and unclog their plumbing. Meanwhile, make sure your kids spend more time on the playground than with their Play-Station. Even if they don"t shed a pound, vigorous exercise will help keep their blood vessels nice and wide, lowering their blood pressure. And of course, they"ll be more likely to eat light and exercise if you set a good example.

单选题{{B}}Passage Four{{/B}} If a mother pushes her small son in a swing, giving only a light force each time he returns, eventually he will be swinging quite high. The child can do this for himself by using his legs to increase the motion, but both the mother's push and the child's leg movements must occur at the proper moment, or the extent of the swing will not increase. In physics, increasing the swing is increasing the amplitude; the length of the rope on the swing determines its natural oscillation period. This ability of an object to move periodically or to vibrate when stimulated by a force operating in its natural period is called resonance. Resonance is observed many times without consciously thinking about it; for example, one may find an annoying vibration or shimmy in an automobile, caused by a loose engine mount vibrating with increasing amplitude because of an out-of-round tire. The bulge on the tire slaps the pavement with each revolution; at the natural resonance point of the engine mount, it will begin to vibrate. Such vibrations can result in considerable damage if allowed to persist. Another destructive example of resonance is the shattering of a crystal goblet by the production of a musical tone at the natural resonant point of the goblet. The energy of the sound waves causes vibration in the glass; as its amplitude increases, the motion in the glass exceeds the elasticity of the goblet, and it shatters. An instrument called a tachometer makes use of the principle of resonance. It consists of many tiny bars, loosely fastened together and arranged so that each bar can slide independently of the others. Movement of the bars causes changes in a dial. When placed next to a rotating motor or engine, the tachometer picks up slight vibrations which are transferred to the resonant bars. These bars begin to move, and the resulting dial may be read to find the revolutions per minute of the motor very quickly.
