PART III Тексты для чтения Прочтите, переведите, выполните задания к текстам. Text 1 Environment Everything that affects an organism during its lifetime is collectively known as its environment. Environment is a very broad concept. For example, an animal like a raccoon is likely to interact with millions of other organisms (bacteria, food organisms, parasites, mates, predators), drink a large number of liters of water, breathe huge quantities of air, and respond to daily changes in temperature and humidity during its lifetime. This list only begins to describe the various components that make up the environment of the organism. Because of this complexity, it is useful to subdivide the concept of environment into abiotic (nonliving) and biotic (living) factors. Abiotic factors include the flow of energy necessary to maintain any organism, the physical factors that affect an organism and the supply of molecules required for an organism’s life functions. The ultimate source of energy for almost all organisms is the sun. Animals obtain their energy by eating plants or other animals that eat plants. Ultimately, the amount of living material that can exist in an area is determined by the plants and the amount of energy they can trap. Other physical factors include such things as climate, age, temperature and daily variations; the type (rain, snow, hail), amount, and seasonal distribution of precipitation; type of soil present and even the three-dimensional shape of the space the organism inhabits. All forms of life require atoms such as carbon, nitrogen, and phosphorus, and molecules such as water to construct and maintain themselves. Organisms constantly obtain these materials from their environment by eating food or carrying on photosynthesis, use them for a period of time as part of their body structure, and return them to their surroundings through respiration, excretion, or death and decay. The biotic factors influencing an organism include all forms of life in its environment. Plants that carry on photosynthesis; animals that eat other organisms; bacteria and fungi that cause decay; and bacteria, viruses, and other parasitic organisms that cause disease are all part of an organism’s biotic environment. The kinds of organisms and the number of each kind are also important in characterizing the environment. Задание 1.

Text 2 Modern Veterinary Care More than 45,000 veterinarians currently practice medicine in the United States, primarily in private hospitals and clinics. Of these, about 60 percent treat small animals such as cats and dogs exclusively; about 10 percent treat large animals such as cattle and other livestock; and some 5 percent specialize in horses. The remainder treats both large and small animals. About 9,000 veterinarians in the United States work in corporations or public institutions, such as pharmaceutical companies, colleges or universities, or in local, state, or federal government agencies such as the United States Army Veterinary Corps. Typical small-animal veterinarians are family advisors as well as animal health care providers. They may help clients select an appropriate species or breed of pet and then guide them in the proper nutrition, grooming, training, and general husbandry of their new pet. A large portion of this practice involves preventive care, such as vaccinating, screening, and treating animals for internal and external parasites, as well as performing operations that prevent pets from bearing unwanted offspring. Small-animal veterinarians also treat their patients’ illnesses and injuries, address the owners’ concerns, and provide references to specialists when necessary. Another important responsibility of veterinarians is to provide humane euthanasia (the act of ending a patient’s life). Large-animal veterinarians work primarily with livestock. They perform vaccinations, parasite control, and neutering, but there are several important differences. Large-animal veterinarians often treat groups of animals rather than individuals. They insure that infectious diseases do not spread from farm to farm. Most patients of large-animal veterinarians are viewed from the standpoint of their economic potential. They may perform artificial insemination on a herd of cows, treat a horse with colic (severe abdominal pain), or assist a sow in delivering its piglets. Large-animal medicine and surgery are often practiced in stables, barns, and open fields rather than in animal hospitals. Veterinarians must, therefore, carry medicine and instruments with them wherever they go to face almost any challenge.

Text 3 History of zoology Humans have always been interested in the animals around them. They have benefited from learning about animals that are a source of food and clothing and other species that are harmful. Animals were first classified in the 4th century BС by the Greek philosopher Aristotle, whose system was based on the similarity of organisms in shape and structure rather than on their phylogenetic lineage. Aristotle classified birds and bats together because they both had wings and could fly. The formal study of many fields of zoology began in the 15th and 16th centuries AD. In the 1500s the Italian artist Leonardo da Vinci and the Greek physician Andreas Veselius demonstrated that the internal anatomy of humans and other vertebrates was similar. The dissection of animals during the next two centuries led to numerous discoveries in anatomy and physiology. In the 1600s the invention of the microscope and the first observation of a single-celled animal, by Dutch microbiologist, Anthony van Leeuwenhoek, evoked new interest and excitement to the field of zoology. Zoological discoveries at the microscopic level continued. During this period Francis Bacon and other scientists worked out general concepts of scientific observation and experimentation that are still in use. In the 1750s an important advance was made by Swedish naturalist Carolus Linnaeus in the fields of taxonomy and systematics. Using some of the ideas of classification developed by John Ray during the late 1600s, Linnaeus devised a scheme for classifying plants and animals on the basis of their presumed phylogenetic relationships. Using the binomial names for genera and species to indicate the similarities between species, his system is still used. The most dramatic development in zoology and all of biology was the 1859 publication of “On the Origin of Species by Means of Natural Selection” by Charles Darwin. Darwin's presentation of the concept of natural selection and evolution provided a universal explanation for the variations, similarities, and differences observed among all organisms. His thesis became the foundation on which modern zoology is based. Задание 1. Подтвердите или опровергните следующие утверждения предложениями из прочитанного текста: 1.

Text 4 Mammals Despite their size differences, the great blue whale and the pygmy shrew have something in common: they are both members of a warm-blooded, air-breathing class of vertebrate (backboned) animals known as Mammalia, or mammals. In many ways mammals are the most highly developed of all creatures. The term mammal explains one important way in which creatures in this class are set apart from other animals. It comes from the Latin mamma, which means “breast”. Every female mammal has special glands, mammae that secrete milk. The females of all but the most primitive mamalian species are viviparous. This means they bear their young alive. The уоung are then fed with milk until they have grown enough to get food for themselves. Hair is a typical mammalian feature. In many whales, however, it exists only in the fetal stages of development. Another basic trait of mammals is their highly developed brains – the most complex known. Particularly well developed is their cerebrum, the part of the brain that controls memory and learning. The mammalian brain enables the young to learn from the experience of their elders. Since the young mammal is dependent on its mother for nourishment, a period of learning is possible. This in turn has brought about a degree of behavioral adaptability unknown in any other group of organisms. Whales, seals, and dogs are among the most intelligent mammals, but monkeys, apes, and humans are the most intelligent of all.
Задание 1. Выберите и переведите предложения, в которых описаны характерные особенности млекопитающих. Задание 2.

(Why) Text 5 The Importance of Bacteria Much of our experience with bacteria involves disease. Although some bacteria do cause disease, many kinds of bacteria live on or in the human body and prevent disease. Bacteria play important roles in the environment and in industry. In most cases the bacteria that cause disease are not part of the bacteria that normally inhabit the body. They are picked up from sick people, sick animals, contaminated food or water, or other external sources. Bacterial disease also can occur after surgery, an accident, or some other event that weakens the immune system. When the immune system is not functioning properly, bacteria that usually are harmless can overwhelm the body and cause disease. These organisms are called opportunistic because they cause disease only when an opportunity is presented. For example, cuts or injuries to the skin and protective layers of the body enable normally friendly bacteria to enter the bloodstream or other sterile parts of the body and cause infection. Surgery may enable bacteria from one part of the body to reach another, where they cause infection. A weakened immune system may be unable to prevent the rapid multiplication of bacteria and other microorganisms. Opportunistic infections became more important in the late 20th century because of diseases such as acquired immunodeficiency syndrome (AIDS), a viral disease that ravages the immune system. Some dramatic infectious diseases result from exposure to bacteria that are not part of our normal bacterial community. Cholera, one of the world's deadliest diseases today, is caused by the bacterium Vibrio cholerae. Cholera is spread in water and food contaminated with the bacteria, and by people who have the disease. After entering the body, the cholera bacteria grow in the intestines, often along the surface of the intestinal wall, where they secrete a toxin (poison). This toxin causes massive loss of fluid from the gut, and an infected person can die of dehydration (fluid loss) unless the lost fluids, and the salts they contain, are replaced. Задание 1. Ответьте на вопросы: 1. Do all bacteria cause disease? 2. Where do bacteria play important roles? 3. In what cases can bacterial disease occur? 4. Can bacteria that are usually harmless cause disease? 5. Why do opportunistic infections become more important in the late 20th century?
Задание 2. Из списка болезней выберите те, о которых идет речь в тексте: tuberculosis, cholera, pneumonia, acquired immunodeficiency syndrome, anthrax. Задание 3. Опишите течение холеры, используя текст и следующие глаголы: to be caused, to be spread, to grow, to secrete, to cause, to die.
PART IV Коммуникативные темы Topic 1 FARM ANIMALS Fauna of the Earth is very rich. Since early days of civilization people began to domesticate wild animals. Animals were domesticated for labour, skin, fur, meat, milk, etc. Farm animals include cattle, swine, sheep, horses, poultry, and rabbits. Cattle include cow, heifer, calf, bull. Modern cattle are usually divided into three types: beef, dairy, and dual purpose. Cattle can be fed hay, grain, pasture grass, silage. They are bred for milk, beef, hide. Swine (hogs) are the most typical meat animals. They comprise sow, pig, and boar. Swine are omnivorous and can scavenge a wide range of foods: barley, wheat, beans, potatoes, by-products of the farm. There are two types of swine: the lard type and the bacon type. They provide pork, lard, skin, bristle. Sheep came from Asia. They include ewe, lamb, ram. They are fed hay, pasture grass. Sheep are valued for wool, hide, milk, mutton. Horses were domesticated in Eurasia. They comprise mare, foal, and stallion. Horses can be divided into draft, coach, and light horses. These farm animals consume hay, grass, and oats. Poultry include hen, cock, chicken; duck, drake, duckling; goose, gosling; turkey. Scientists estimate that they were domesticated roughly 8000 years ago in what is now Thailand and Vietnam. The types of poultry have been developed into egg type, meat type and general purpose type. Eggs, meat, feathers, down are useful products obtained from poultry. Poultry consume grain mixture.
