Exercise 8. Read the text, make up a plan to it. Medicinal Plants Since time immemorial man has known about the medicinal properties of plants and widely -sed them for all practical purposes. At present the attention to medicinal plants as natural sources of drugs has greatly increased. Ten thousand plant detectives try to find new plants rossessing medicinal properties on five continents and all seas. Different parts of a plant may be used for medicinal purposes: roots and rhizomes, fruits;r.d seeds, flowers and inflorescences, stems and leaves. All these parts are collected in a certain reriod of time. It is well-known that the proper time of harvesting or collecting plants and herbs is during ■'-at period when active constituents of the plant are highest in their number and quality. Roots ir.d rhizomes are collected in autumn after the vegetative processes have finished. Bark is:: ilected in spring before these processes begin. Leaves and flowering tops are collected when: r. otosynthesis is most active which is usually about the time of flowering and before the maturing::" the fruit and seed. Flowers are collected in the time of pollination. Fruit may be collected r.ther before or after the ripening period. Seeds may be collected when fully matured. Proper storage and preservation are an important factor in maintaining a high degree of:-ality of the drug. Thus, too much moisture increases the weight of the drug, decreases the amount of active constituents. Air and light affect drugs, which are strongly colored, produci". changes in constituents of drags. All parts of the plant differ as to the shape, taste, color, odor, and pharmacological activi:;. Thus, the usual shapes for fruits and seeds are globular, elliptical, ovoid, conical, etc. The odor c: a drug of plant origin may be either distinct or indistinct, depending upon the amount of volatile constituents the drug possesses. It is described as aromatic, balsamic, spicy, camphorous, eu When it is difficult to compare the odor with other substances, it is described as characteristic According to taste substances may be classified into four groups: 1) those possessing a true taste, such as acid, sweet, alkaline, bitter; 2) those possessing no taste and thus being tasteless;
3) those possessing a characteristic odor which gives name to the so-called "taste". The;, may be grouped broadly into those which are agreeable or pleasant (aromatic, balsamic, spic\ and disagreeable or unpleasant (alliaceous, camphorous, etc.); 4) those giving certain sensation to the tongue. Such substances may be classified as mucilaginous, oily, astringent, pungent, acrid, nauseous. The taste, color and odor of drugs are officially standardized with the help of drug description, are of the lightness and strength of the color. Reserpine is described as "a white or pale to slightly yellowish, odorless, crystalline powder". Olive oil is described as "a pale yellow liquid which sometimes has a greenish tint"; rhizome and roots of valerian as "light brown or yellow brown, odor strong and peculiar, taste - spicy, sweetish-bitterish". Pharmacological activity of certain drugs is established using different tests and methods, such as chemical analysis for the determination of presence of inorganic elements, a chemical analysis for the determination of the official activity, chromatographic study to separate and analyse constituents and inert materials occurring in drugs. Exercise 9. Read the sentences. Add attributes to the underlined words. 1. Parts of a plant such as roots, rhizomes, fruits, bark, seeds, flowers, leaves, etc. may be used for medicinal purposes. 2.

/. Health Service in Ukraine In Ukraine medical help is available in hospitals, polyclinics, and also in medical centers •] such places as factories and schools. Health service is based on local therapeutists as they are the first to diagnose. Some certain district is appointed to a polyclinic and this district is divided into several areas. Each area is irpointed to a certain therapeutist. All the people who live in that area visit their appointed doctor. An average number of people, visiting their doctor every day, is 20-25, but when there > an epidemic of cold, this number is 50-60 people a day. There is some tendency which is -: wadays widely discussed, that a person him- or herself can choose the doctor he or she vants to visit. A person can call his local therapeutist so that the doctor will come and see his ■ ment. A therapeutist examines a patient, assigns some treatment, prescribes some medicines and r. es a medical certificate. In a hospital there is also a therapeutic department, where pneumonia, bronchitis or asthma "e treated. There also exists a wide network of ambulance service in Ukraine. It was founded - Kharkivin 1905. Nowadays there are a lot of paid clinics where one can get any kind of medical help. Many::hem are specialized: dentist offices, eye care centers, etc. There also exist some medical associations in Ukraine, such as Ukrainian Diabetes ---ociation. About 1 million people in Ukraine suffer from this disease. In this association:.-pie can get medical help or medicines free of charge.
2. Doctors and Patients An ordinary doctor (sometimes called G.P., i.e. general practitioner) is sometimes a -.cum or a surgeon (i.e. able to perform operations), and quite often he is both physician _: 4irgeon. But if the illness is serious, or the operation a big one. he will advise you to..' _ >pecialist. You will go to the specialist or he will come to you, and if you must have an - г-ition, he will advise you to go to a hospital or a nursing home where they will have all the -.. еччагу equipment. if your teeth need attention, stopping, filling, or extracting, or if you need false teeth:...res), then you go to the dentist. Common illnesses are: cough, cold, influenza (flu), sore throat. Children often get: measles (including "German" measles), mumps, scarlet fever -~. whooping cough. You can generally know that a child is not well if he/she has a tempera:,: (i.e. it is above the normal 93.4° Fahrenheit). Older people suffer from indigestion, rheumatism, heart troubles and blood pressure. Some diseases are infectious or contagious, and great care must be taken by people.;:. have these illnesses so that they don't pass them on to other people. You may have toothache, stomachache, headache, earache. All these give you pain. T'r.e-you may get a bum, a scald, or a wound; you may get blood poisoning, or break a bone. Some of the commonest things used to prevent or cure illnesses are medicines: p:l-powders, ointments, sleeping draughts, injections, bandages, tinctures, disinfectants, antiseptic tablets, drops and others. Even in medical clinics you'll sometimes have to wait for some time before you see _ doctor. The advantage of a medical clinic over a regular doctor's office is that you don't have: wait for an appointment. Patients are seen on a first come, first served basis. Doctors aren't supposed to dispense drugs other than free samples. What your doctor gh e -you is a prescription for medicine and you'll have to go to a pharmacy, a drug store, or tc _ chemist's. Sometimes a pharmacist will call your doctor to confirm the dose or nature c: prescription. In most American cities you can find quick medical care at what are called "walk-in medic;, clinics". If you're sick and don't have a doctor, such clinics can provide prompt and relati\ e. inexpensive treatment for minor illnesses. 3. Medicine and Health Care In the final decades of the 20th century, Americans increasingly view good health ^ something to which they have a right. They believe they have a right to good health becau>e widespread advances in medical research have made it possible to treat many previous, "untreatable" diseases. These rising expectations regarding health care in the United States are the result of vastly increased medical knowledge and the belief that in an affluent ar.rc democratic society all people should have access to well-trained physicians, fully equippec hospitals and highly sophisticated procedures for the treatment of disease. Physicians Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contractual relationship u it-one or more hospitals in the community. They send their patients to this hospital, which usual/, charges patients according to the number of days they stay and the facilities (operating room tests, medicines) that they use. Some hospitals belong to a city, a state or in the case of veteran's hospitals a federal government agency. Others are operated by religious orders or other nonprofit groups. Still others operate for profit. Some medical doctors are on salary. Salaried physicians may work as hospital stan members, or residents, who often are still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service. Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100,000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would-be physicians first attend college for four years, which can cost nearly $ 20,000 annually at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can be more than $10,000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency in a hospital, the first year as an intern, an apprentice physician. The hours are long and the pay is -datively low. Setting up a medical practice is expensive, too. Sometimes several physicians will decide:o establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies. Medical Costs Physicians' fees are only one reason for rising health costs in the United States. Medical research has produced many tests to diagnose, or discover patients' illnesses. Physicians usually eel obliged to order enough tests to rule out all likely causes of patient's symptoms. A routine.moratory bill for blood tests can easily be more than $ 100. Sophisticated new machines have been developed to enable physicians to scan body mans. One technique involves the use of ultrasound to produce images. Others use computers capture and analyze images produced by X-rays or magnetic fields.
4. Computers Concern You When Charles Babbage, a professor of mathematics at Cambridge University, invented the - calculating machine in 1812, he could not even imagine the situation we find ourselves in my. Nearly everything we do in the modern world is helped, or even controlled, by computers, mputers are used more and more extensively in the world today for the simple reason that " e;. are far more efficient than human beings. They have much better memories and can store -re amounts of information, and they can do calculations in a fraction of the time taken by..man mathematician. No man alive can do 500,000 sums in one second, but an advanced muter can. In fact, computers can do many of the things we do, but faster and better. Many people associate computers with the world of science and mathematics, but they are great help to scholars in other subjects: in history, literature, medicine and so on. It's now ■ - - mle for a scholar to find a book or article he needs very quickly, which, when a million or - -. new books are published each year, is quite an advantage. So computers can help us to.: - ith the knowledge explosion in many ways.
5. Hobbies and Leisure Time Occupations 7 mm the old English word hobby meaning horse, came the modern word hobbyhorse. > л dummy horse attached to a performer who pretended to be riding a horse in a play. mmce. Hobbyhorse has been shortened to hobby to describe any favorite leisure time. - m:on. This word has become rather common in modern usage. Leisure time occupations, or hobbies, can be divided into four groups: doing things, такі: \. things, collecting things and learning things. Of these four groups, doing things is perhaps the most popular. It includes a wide range of activities, from gardening to sailing and from che>: to foreign travel. Some of these hobbies require very little equipment while others require considerably more. There is also a choice between mental and physical activities, indoor anc outdoor pursuits, etc. Leisure time occupations can be more or less active. A real hobby is usually defines as something creative and individual, sometimes even as something obsessive, unusual or eccentric. Even if one's hobby does not solely consist of the study of particular subjects, a real hobbyist wants to learn more about his chosen subject and its history, so that he can become e. real expert at it. Outdoor Activities or Activities outside the Home Sports activities: athletics, gymnastics, cycling, swimming, sailing, rowing, canoeing, racing, skiing, mountaineering, climbing. Playing games: football/soccer, handball, volleyball, tennis, table tennis, basketball, baseball, water polo, golf, badminton, bowling, judo, fencing, boxing and taking part in competitions. Other activities: gardening, fishing, traveling (e.g. visiting the countryside, the seaside, museums, art exhibitions, historical places), walking, driving a car, car maintenance, singing in a choir, watching outdoor sports, betting on matches or races.
6. Are You Left-Handed? Life is easier if you're right-handed. You can open a can of tomatoes, use a pair of scissors or write a cheque without problems. People won't think that you're strange, and you'll be one of the 90 % of people who use their right hand more than their left. Many animals are "right-handed" or "left-handed" too; what is interesting about human beings is that many choose to be right-handed. What makes us different? In earlier times left-handed people were sometimes thought to be bad or even dangerous and were sometimes even killed. Quite recently, children who wanted to use their left hands were taught to use their right instead. The teacher of King George VI of England (1895-1952) tied his left hand behind his back to make him use his right, and it was probably because of this that he had speech problems later in his life. However, modern ideas about how children use their hands are very different. Some doctors now think that the choice is made when babies are still very young. Look at this advice from a modern book for parents. There is no natural law which states that one hand is superior to the other so it should never bother you if your child is left-handed. You may think that by "encouraging" your child to use his right hand instead of his left one you're doing him a favor for later life so that he'll never have to suffer the minor annoyances of right-handed potato peelers or scissors. You are not. And, what's more, you could well risk causing psychological side-effects like stuttering as well as reading and writing difficulties by altering what your baby's brain naturally wants to do. But why is anyone left-handed? Why aren't we all right-handed or perhaps 50 % right-handed and 50 % left? Psychologist Dr. Marian Annett thinks that a long time ago people used both hands equally; what changed things was that human beings learned to speak. The left hemisphere controls the right-hand side of the body and the right controls the left. Speech became connected to the left hemisphere of the brain; and as speech became more and more important, so the left hemisphere became more and more powerful. As the left hemisphere became more important, so the right-hand side of the body was used more; right-handedness became more common, and the functions of the right hemisphere became weaker. This means that left-handers are often slower to speak and read than right-handers. But left-handed people have advantages too.
