武汉为什么我硬一会儿就软了武汉阿波罗男子看病收费怎么样33Plankton浮游生物33 Plankton浮游生物. Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small the human eye to see. They drift about lazily with the currents, providing a basic food many larger animals.Plankton has been described as the equivalent of the grasses that grow on the dry land continents, and the comparison is an appropriate one. In potential food value, however, plankton far outweighs that of the land grasses. One scientist has estimated that while grasses of the world produce about 9 billion tons of valuable carbohydrates each year, the sea’s plankton generates more than twice as much.Despite its enormous food potential, little effect was made until recently to farm plankton as we farm grasses on land. Now marine scientists have at last begun to study this possibility, especially as the sea’s resources loom even more important as a means of feeding an expanding world population.No one yet has seriously suggested that “ plankton-burgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among marine scientists.One type of plankton that seems to have great harvest possibilities is a tiny shrimp-like creature called krill. Growing to two or three inches long, krill provides the major food the great blue whale, the largest animal to ever inhabit the Earth. Realizing that this whale may grow to 0 feet and weigh 0 tons at maturity, it is not surprising that each one devours more than one ton of krill daily.浮游生物数十亿吨的被称为"浮游生物"的小动物、植物散布在世界的海洋中这些小的动、植物大多太小而难以被人眼看到它们随波逐流,为许多较大的动物提供了基本的食物浮游生物曾被描述为生长在大陆陆地上的各种草类的海洋对应物这种比喻是恰当的然而就潜在的食物价值而言,浮游生物远胜于草类一位科学家曾经估计,世界上的草类每年生产大约90亿吨有用的碳水化合物,而海洋里的浮游生物每年生产的碳水化合物多于此数的两倍尽管浮游生物具备巨大的食物潜能,但直到最近人们还很少象种植草类那样付出努力养殖浮游生物现在,海洋科学家们至少已开始研究这种可能性全球人口不断扩张,海洋资源作为食品的重要性日益突出现在还没有人认真说过"浮游生物汉堡"会很快在世界上流行起来然而,作为一种可能养殖的补充性食物资源,浮游生物正引起了海洋科学家们相当大的兴趣一种似乎具有很大收获可能性的微小的虾状浮游生物被称为鳞虾鳞虾长至~3英寸长时即成为地球上曾居住过的最大动物--蓝鲸的主要食物成熟的蓝鲸可以达到0英尺长,0吨重,所以每头鲸每天吞食1吨多的鳞虾一点也不让人吃惊 6武汉小便很疼是怎么回事 7Folk Culture7 Folk CulturesA folk culture is a small isolated, cohesive, conservative, nearly self-sufficient group that is homogeneous in custom and race with a strong family or clan structure and highly developed rituals. Order is maintained through sanctions based in the religion or family and interpersonal. Relationships are strong. Tradition is paramount, and change comes infrequently and slowly. There is relatively little division of labor into specialized duties. Rather, each person is expected to perm a great variety of tasks, though duties may differ between the sexes. Most goods are handmade and subsistence economy prevails. Individualism is weakly developed in folk cultures as are social classes. Unaltered folk cultures no longer exist in industrialized countries such as the ed States and Canada. Perhaps the nearest modern equivalent in Anglo America is the Amish, a German American farming sect that largely renounces the products and labor saving devices of the industrial age. In Amish areas, horse drawn buggies still serve as a local transportation device and the faithful are not permitted to own automobiles. The Amish’s central religious concept of Demut “humility”, clearly reflects the weakness of individualism and social class so typical of folk cultures and there is a corresponding strength of Amish group identity. Rarely do the Amish marry outside their sect. The religion, a variety of the Mennonite faith, provides the principal mechanism maintaining order.By contrast a popular culture is a large heterogeneous group often highly individualistic and a pronounced many specialized professions. Secular institutions of control such as the police and army take the place of religion and family in maintaining order, and a money-based economy prevails. Because of these contrasts, “popular” may be viewed as clearly different from “folk”. The popular is replacing the folk in industrialized countries and in many developing nations. Folk-made objects give way to their popular equivalent, usually because the popular item is more quickly or cheaply produced, is easier or time saving to use or leads more prestige to the owner. 民间文化民间文化是小型的、孤立的、紧密的、保守的、近乎自给自足的群体,具有同样的习俗、同样的人种和强有力的家庭或部族结构以及高度发展的宗教仪式秩序由宗教或家庭的约束来维持,成员间的关系非常紧密,传统至高无上,很少有变动且变动缓慢劳动专业分工相对较少每个人都要做各类活计,尽管男女两性分工不同绝大多数物品是手工制造的,经济一般为自给自足型个人主义和社会阶层在民间文化群体中的发展十分薄弱在象美国和加拿大这样的工业化国家里,一成不变的民间文化群体已不复存在了在当代美洲的英语区,与民间文化最相似的群体也许算是AmishAmish是美国的德裔农耕部落,他们基本上拒绝接受工业时代的大多数产品和节省劳力的设施在Amish地区,轻便马车仍是当地的交通工具,信徒们不允许拥有汽车Amish宗教中的核心观念Demut即谦卑典型地反映了在民间文化群中个人主义和阶级的不发达而与此同时,Amish对群体的认同性却十分强Amish人很少和他们宗派以外的人通婚其宗教,作为Mennonite信仰的一种,提供了维护秩序的主要机制相反,大众文化是包含不同种族的大群体,通常高度个性化而且不断在变化人际关系冷漠,劳动分工明确,由此产生了许多专门的职业世俗的控制机构,比如警察和军队,取代了宗教和家庭来维持秩序,而且实行的是货币经济由于存在着这些差异,;大众的;与;民间的;可谓大相径庭在工业化国家以及许多发展中国家里,大众文化正在取代民间文化民间制造的物品正让位于大众化产品,这通常是因为大众化的物品制造起来更快、更便宜,用起来更容易、更方便或者是能给其所有者带来更多的威望 680我希望这一天能够带给我无畏远行的胸怀,即使旅途没有光亮的照耀;我还希望这一天能够带给我善解人意的心A Morning WishThe sun is just rising in the morning of another day. What can I wish that this day may bring me? Nothing that shall make the world or others poorer, nothing at the expense of other men; but just those few things which in their coming do not stop me but touch me rather, as they pass and gather strength.I wish that this day could bring me a few friends, who understand me, and yet remain my friends; I also wish that this day could bring me a work to do which has real value.I wish that this day could bring me a mind unafraid to travel, even though the trail be not blazed, and I wish that this day could bring me an understanding heart.I wish that this day could bring me a sight of the eternal hills, and the blue sea stretching to the horizon, and of something beautiful which the hands of men have made.I wish that this day could bring me a sense of humor, and the power to laugh, a little leisure with nothing to do.And I crave a few moments of quiet, silent meditation in the morning of this day.You’re listening to Faith Radio Online-Simply to Relax, I’m Faith. I also wish that this day could bring me the patience to wait the coming of these things, with the wisdom to know them when they come, and the wit not to change this morning wish of mine. 7330武汉人民医院有治疗输精管梗阻吗

华中科技大学同济医学院附属协和医院男科咨询那鹿被车撞死了一个在狭窄山路上开车经过的人看见有东西微微一动, 就停下了车蜷缩在死鹿旁的是头脐带未断的初生幼鹿“我想你活的希望不大, ”开车人一边扯断脐带一边对这个小生灵说道, “但至少我要把你带到一个暖和的地方”The Deer and the Nursing Home The deer had been struck and killed by a car. A passing motorist on the narrow mountain road saw a slight movement and stopped. Huddled beside the dead deer was a fawn1) with the umbilical cord) still attached. “I don’t suppose you have a chance, ”the motorist told the tiny creature as he tied off the cord, “but at least I’ll take you where it’s warm. ”The nearest place was the powerhouse of New Jersey’s Glen Gardner Center Geriatrics, a state institution. Maintenance men there quickly produced rags to make a bed behind the boiler the fawn. Then they took a rubber glove, pricked pinholes3) in a finger, diluted) some milk and offered it to the fawn, who drank eagerly. With the men taking turns feeding the fawn, the little deer’s wobbly legs and curiosity soon grew strong enough to bring it out from its bed behind the boiler. On their breaks, the men petted and played with the baby. “If it’s a female, we’ll call her Jane Doe, ”they laughed. But it was a male, so they taught him to answer to“Frankie, ”short Frank Buck. Frankie became especially attached to one of the men, an electrician named Jean. On nice days, Frankie stepped outside with his new friend, enjoying the fresh air and scratches behind the ears. Sometimes other deer came out of the woods to graze. When Frankie caught their scent, his head came up. “You’d better tie him or we’ll lose him, ”someone commented. Jean shook his head. “He’ll know when it’s time to go, ”he said. Frankie began following Jean on his rounds, and the slight, white-haired man followed by the delicate golden fawn soon became a familiar sight. One day a resident, noticing Frankie waiting by a door Jean, invited the deer in. Glen Gardner housed old people who had been in state mental hospitals and needed special care. When Frankie was discovered in side, the staff rushed to put him outside. But when they saw how eagerly one resident after another reached out to touch him, they let him stay. When Frankie appeared, smiles sp and people who seldom spoke asked the deer’s name. Discovering a line in front of the payroll5) clerk’s window one day, Frankie companionably joined it. When his turn came , the clerk peered out at him. “Well, Frankie, ”she said, “I wouldn’t mind giving you a paycheck. You’re our best social worker.”The deer had the run of Glen Gardner until late fall, when the superintendent noticed he was growing antlers6). Fearful he might accidentally injure a resident, the supervisor decreed banishment. Frankie continued to frequent the grounds, but as the months passed he explored farther a field. When he was a year old, the evening came when he didn’t return to the powerhouse;now he was on his own. Still, every morning he was there to greet Jean, exploring the pocket the treat Jean always brought, and in the afternoon he would reappear. Residents who had refused to go outside bee would join him on the front lawn to scratch his ears. George, a solitary7) resident with a speech defect who didn’t seem to care if people understood him or not, taught Frankie to respond to his voice, and they often walked together. When Frankie was two years old――a sleek creature with six-point antlers and a shiny coat――he failed to show up one April morning. Nor did he answer anyone’s calls. It was late the next day bee Jean and George found him lying on a sheltered patch of ground. His right front leg was shattered, jagged splinters8) of bone jutted through the skin. “Oh, you old donkey, ”Jean whispered. “What happened?”The deer’s eyes were clouded with pain, but he knew Jean’s voice and tried to lick his hand. “There’s no way to set a break like that without an operation, ”said the veterinarian who examined Frankie. They would have to haul Frankie out of the woods on an improvised litter and drive him to Round Valley Veterinary Hospital, five miles away. On the day of Frankie’s surgery, the surgeon, Dr. Gregory Zolton, told Jean, “You’ll have to stay with me while I operate. I’ll need help. ”Jean’s stomach did a flip-flop, but he swallowed hard and nodded. During the two-hour procedure, Dr. Zolton took bone from Frankie’s shoulder to make a graft between the broken bones and then screwed a steel plate across it. “He said a leg that wasn’t strong enough to run on wasn’t any good to a deer, ”recalls Jean. After the surgery, they took Frankie to an unused horse stable on Glen Gardner’s grounds, and Jean sat in the straw beside the recovering deer. He stroked Frankie’s head and held him whenever the deer tried to struggle to his feet. Finally, as the sun was coming up, Jean took his own stiff bones home, cleaned up and went to work. By the seventh day, Jean called Dr. Zolton to say it was impossible to hold Frankie still his antibiotic9) injections. The surgeon laughed. “If he’s that lively, he doesn’t need antibiotics. ”But he warned that Frankie must be kept inside eight weeks. If he ran on the leg bee it knitted, it would shatter. “Whenever anyone went to visit him, Frankie showed how eager he was to get out,”recalls Jean. “He‘d stand there with his nose pressed against a crack in the door. He smelled spring coming. ”When word had come that Frankie had survived the operation, the residents’ council at Glen Gardner had called a meeting. Mary, the president, told the group, “There’s no operation without a big bill. Now, Frankie’s our deer, right?”The residents all nodded. “So we’ve got to pay his bill. ”They decided to take up a collection and hold a bake sale. The day Dr. Zolton’s bill arrived, Mary called a meeting. The others watched silently as she opened the envelope. “Oh, dear, ”she murmured bleakly, “we owe $39. ”They had managed to collect only $5. Not until she shifted her bifocals) did she notice the handwriting, which :“Paid in Full――Gregory Zolton, D. V. M. ”When Frankie’s confinement was over, Frankie’s friends gathered by the stable door. It was mid-June and grass was knee-deep in the meadow. The buck’s wound was beautifully healed――but would the leg hold?Jean opened the barn door. “Come on, Frankie, ”he said softly. “You can go now. ”Frankie took a step and looked up at Jean. “It’s all right, ”Jean urged him. “You’re free. ”Suddenly Frankie understood. He exploded into a run, flying over the field like a greyhound, his hooves barely touching the ground. “He‘s so glad to be out, ”Mary said wistfully, “I don’t think we’ll ever see him again. ”At the edge of the woods, Frankie swerved. He was coming back. Near the stable he wheeled again. Six times he crossed the meadow. Then, flanks heaving, tongue lolling, he pulled up beside them. Frankie had tested his leg to its limits. It was perfect. “Good.”said George distinctly. Everyone cheered. Soon Frankie was again waiting Jean by the electric shop every morning. In the fall Jean put a yellow collar around Frankie’s neck to warn off hunters. The mountain was a nature preserve, with no hunting allowed, but poachers frequently sneaked in. One day a pickup truck filled with hunters drove up to the powerhouse. When the tailgate) was lowered, Frankie jumped down. The hunters had about him and, spotting the yellow collar, figured it must be Frankie. Every hunting season, George and the other people at Glen Gardner debate whether to lock Frankie in the stable his own safety――and their peace of mind. But each fall, the vote always goes against it. Frankie symbolizes the philosophy of Glen Gardner, which is to provide care but not to undermine independence. “A deer and a person, they each have their dignity, ”Jean says. “You mustn’t take their choices away. ”So Frank Buck, the wonderful deer of Glen Gardner, remains free. He runs risks, of course, but life is risk, and Frankie knows he has friends he can count on.□by Jo Coudert 58 6Vision6.Vision Human vision like that of other primates has evolved in an arboreal environment. In the dense complex world of a tropical est, it is more important to see well that to develop an acute sense of smell. In the course of evolution members of the primate line have acquired large eyes while the snout has shrunk to give the eye an unimpeded view. Of mammals only humans and some primates enjoy color vision. The red flag is black to the bull. Horses live in a monochrome world .light visible to human eyes however occupies only a very narrow band in the whole electromagnetic spectrum. Ultraviolet rays are invisible to humans though ants and honeybees are sensitive to them. Humans though ants and honeybees are sensitive to them. Humans have no direct perception of infrared rays unlike the rattlesnake which has receptors tuned into wavelengths longer than 0.7 micron. The world would look eerily different if human eyes were sensitive to infrared radiation. Then instead of the darkness of night, we would be able to move easily in a strange shadowless world where objects glowed with varying degrees of intensity. But human eyes excel in other ways. They are in fact remarkably discerning in color gradation. The color sensitivity of normal human vision is rarely surpassed even by sophisticated technical devices.视觉人类的视觉,和其它灵长目动物的一样,是在丛林环境中进化出来的在稠密、复杂的热带丛林里,好的视觉比灵敏的嗅觉更加重要在进化过程中,灵长目动物的眼睛变大,同时鼻子变小以使视野不受阻碍在哺乳类动物中,只有人和一些灵长目动物能够分辨颜色红旗在公牛看来是黑色的,马则生活在一个单色的世界里然而,人眼可见的光在整个光谱中只占一个非常狭窄的频段人是看不到紫外线的,尽管蚂蚁和蜜蜂可以感觉到与响尾蛇不同,人也不能直接感受到红外线响尾蛇的感觉器可以感受波长超过0.7微米的光线如果人能感受到红外线的话,这世界看上去将十分不同,而且恐怖到那时,将与夜的黑暗相反,我们能轻易地在一个奇异的没有阴影的世界里走动任何物体都强弱不等地闪着光然而,人眼在其它方面有优越之处事实上,人眼对颜色梯度具有非凡的分辨能力普通人类的视觉感受色的灵敏程度,甚至连精密的技术装备都很难超越 679武汉包皮医院武汉临床生殖保健科
