20、 Types of Blood You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. Howev er, special care must be taken in selecting new blood for you. If the blood is t oo different from your own, the transfusion could kill you. There are four basic types of blood: A, B, AB, and O. A simple test can ind icate a person’s blood type. Everybody is born with one of these four types of b lood. Blood type, like hair color and height, is inherited from parents. Because of substances contained in each type, the four groups must be transf used carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, b ut AB may receive A or B. O can give to any other group; hence, it is often call ed the universal donor. For the opposite reason, AB is sometimes called the univ ersal recipient. However, because so many reactions can occur in transfusions, p atients usually receive only salt or plasma ( liquid ) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way , it is possible to avoid any bad reactions to the transfusion. There is a relationship between your blood type and your nationality. Among Europeans and people of European ancestry, about 42 percent have type A while 45 percent have type O. The rarest is type AB. Other races have different percenta ges. For example, some American

21、 Public Health in Rome and Arab The Romans built great /!aqueducts to carry fresh water from the mountains to the cities. Many of these aqueducts are still standing today. The Romans also built great pipes under the ground to carry away the sewage. In Romes these sewa ge pipes (sewers) are still used today; it is 2,000 years old. The Roman Emperor s even set up a government Wealth service. They built the first great public hos pitals in Europe, and they paid doctors to look after poor people. Then the Roman Empire fell to pieces, these civilised methods of treatment d isappeared from most of Europe, for more than a thousand years. People went back to the old ways. They lived in dirty conditions which helped to cause diseases; and they asked God to cure the diseases. They shut up mentally sick people in p risons. Or they burnt them alive because they were supposed to have magic power. But the work of the Greek and Roman doctors was lost. Over a thousand years ago, the Arabs moved into many of the Mediterranean countries. They took big par ts of the old Roman lands. They translated the Greek and Roman medical books int o Arabic. Arab doctors themselves made many new discoveries. When civilization at last came back to Europe, men once again translated the Greek and Roman works on medicine into Latin. Slowly very sloppily European doc tors discovered again the things that the Greeks and Romans had known so long ag o. Slowly, they began to make new discoveries. They found out more about the way the body works the way our blood goes round our bodies, the way our nerves send messages from our brains to our muscles, the way these muscles move our bodies.

22、 Population Densities The average population density of the world is 47 persons per square mile. Continental densities range from no permanent inhabitants in Antarctica to 211 per square mile in Europe. In the western hemisphere, population densities range from about 4 per square mile in Canada to 675 per square mile in Puerto Rico. I n Europe the range is from 4 per square mile in Iceland to 831 per square mile I n the Netherlands. Within countries there are wide variations of population dens ities. For example, in Egypt, the average is 55 persons per square mile, but 1,3 00 person inhabit each square mile in settled portions where the land is arable. High population densities generally occur in regions of developed industri alization, such as the Netherlands, Belgium, and Great Britain, or where lands a re intensively used for agriculture, as in Puerto Rico and Java. Low average population densities are characteristic of most underdeveloped countries. Low density of population is generally associated with a relatively low percentage of cultivated land. This generally results from poor quality land s. It may also be due to natural obstacles to cultivation, such as deserts, moun tains, or malaria (疟疾)-infested jungles; to land uses othe r than cultivation, as pasture and forested sand; to primitive methods that limit cultivation; to so cial obstacles; and to land ownership systems which keep land out of production. More ***nomically advanced countries of low population density have, as a rule, large proportions of their populations living in urban areas. Their rural population densities are usually very low. Poorly developed countries of corresp ondingly low generally population density, on the other hand, often have a conce ntration of rural population living on arable land, which is as great as the rur al concentration found in the most densely populated industrial countries.

23、 Suntans and Skin Cancer Between now (June) and Labor Day, millions of Americans will offer up thei r bodies to the sun’s rays. A tan indicates health and beauty, and most sun wors hippers will sacrifice a lot to achieve it ? Including themselves. With each hou r, the sun’s ultraviolet (紫外线) radiation produces irrever sible (不可逆的) dam age, hastening the development of unsightly wrinkles. And with each year on the beach or rooftop, the sunbather increases his risk of getting skin cancer. Skin cancer is by far the most common form of cancer. An estimated 400,000 new cases will be detected this year in the United States, and almost all of th em can be blamed on overexposure to the sun. Fortunately, most of these cancers are highly curable. But they can be disfiguring and take time to treat. For that reason, sun worshippers should treat deity with a good deal of awe ( 敬畏). Sunburn, of course, is the initial hazard posed by UV radiation. Prolonged exposure to UV, however, interferes with the production of collagen fibers in t he dermis, causing the skin to lose elasticity and creating premature wrinkles. Further deterioration of the dermis deprives the epidermis of nutrition and caus es it to b***me thin and dry. Cancer is UV’s final insult. Shortwave radiant energy, especially from the UV-B band, breaks the strands of DNA. Enzymes work constantly to rearrange the DNA into proper sequence, but with repeated UV exposure, the repair process may eventually break down. Then the mutant DNA may produce a colony of cancer cells. But skin cancer may be avoided with a good dose of common sense. People wi th fair skin and blue eyes who burn easily stand the highest risk. Special dange r spots are the parts of the body most constantly exposed to the sun, such as th e cheeks, nose, lower lip and the ears. People who have already developed precan cerous lesions or had one skin-cancer growth stand a greatly increased chance of developing others. Dermatologists r***mmend avoiding the sun when it is most in tense?between 11 ?a.m.? and 3 p.m. Anyone who insists on sunbathing should use a g ood sun screen. These lotions and salves contain chemicals, such as para-aminobe nzoic acid, that block out the burning UV-B radiation while permitting the tanni ng rays to reach the skin.

25、 Smoking and Cancer Americans smoke six thousands million cigarettes every year (1970 figures). This is roughly the equivalent of 4195 cigarettes a year for every person in the country of 18 years of age or more. It is estimated that 51 % of American men s moke compared with 34 % of American women. Since 1939, numerous scientific studies have been conducted to determine whe ther smoking is a health hazard. The trend of the evidence has been consistent a nd indicates that there is a serious health risk. Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking, particularly cigarette smoking is associated with a shortened life expectancy. Cigarette smoking is believed by most research workers in this field to be a n important factor in the development of cancer of the lungs and cancer of the t hroat. Male cigarette smokers have a higher death rate from heart disease than O n-smoking males. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply. The majority of physicians and researchers consider these relationships proved to their satisfaction and say, ’Give up smoking! If you don’t smoke, don’t start! ’ . It might be helpful to look at what tobacco-smoking actually does to the hum an body. Smoke is a mixture of gases, vaporized chemicals, minute particles of a sh, and other solids. There is also nicotine, which is a powerful poison, and bl ack tar. As the smoke is breathed in, all these components form deposits on the membranes of the lungs. One point of concentration of deposits is where the air tube divides. Most lung cancer begins at this point. Smoking also affects the heart and blood vessels. It is known to be related to Beurger’s disease, a narrowing of the small veins in the hands and feet that can cause great pain. Smokers also die much more often from heart disease. While all tobacco-smoking affects life expectancy and health, cigarette smok ing appears to have a much greater effect than cigar or pipe smoking. However, n icotine consumption is not diminished by the latter forms, and current research indicates a causal relationship between all forms of smoking and cancer of the m outh and throat. Filters and low tar tobacco are claimed to make smoking to some extent safer, but they can only marginally reduce, not eliminate the hazards.
