Natural Medicines

Since earliest days, humans have used some kinds of medicines. We know this because hu-mans have survived. Ancient treatments for injury and disease were successful enough to keep hu-mans from dying out completely.

They were successful long before the time of modem medicine. Before the time of doctorswith white coats and shiny （发亮的）nstruments. Before the time of big hospitals with strangeand wonderful equipment.

Many parts of the world still do not have university-educated doctors. Nor do they have ex-pensive hospitals. Yet injuries are treated. And diseases are often cured. How？ By ancient meth-ods. By medicines that might seem mysterious, even magical （有魔力的）Traditional medicinesare neither mysterious nor magical, however.

Through the centuries, tribal (部落的) medicine men experimented with plants. They foundmany useful chemicals in the plants. And scientists believe many of these traditional medicinesmay provide the cure for some of today&39;s most serious diseases.

Experts say almost 80% of the people in the world use plants for health care. These naturalmedicines are used not just because people have no other form. of treatment. They are used be-cause people trust them. In developed areas, few people think about the source of the medicinesthey buy in a store. Yet many widely-used medicines are from ancient sources, especially plants.Some experts say more than 25 % of modem medicines come, in one way or another, from nature.

Scientists have long known that nature is really a chemical factory. All living things containchemicals that help them survive. So scientists&39; interest in traditional medicine is not new. But ithas become an urgent concern. This is because the earth&39;s supply of natural medicines may bedropping rapidly.

根据以下材料，回答题

Ward off Travel Bugs

（1） As the holiday season approaches， so does the prospect of jet lag， an upset stomach or sunburn.

With care and some help fi"om natural sources， however， it is quite possible to avoid these problems.

（2） You can start to prepare a couple of weeks before you leave. Food poisoning will make any holiday miserable， but by taking some medicine such as lactobacillus and bifidobacteria， you can reduce the likelihood of poisoning caused by food or water tainted （感染，污染） with unfamiliar bacteria.

（3） By improving the bacteria balance in your digestive tract， you crowd out the pathogenic （病原的）bacteria and stop them gaining a foothold. The beneficial bacteria also produce gentle but effective natural antibiotics （抗生素） in yourgut.

（4） In many holiday locations you need to remember the basics: drink bottled water， avoid undercooked meat and ensure that food hygiene （卫生） is adequate. If you get food poisoning，drink plenty of water to stay hydrated（保持水分）and see a doctor. However， if you detect diarrhea（腹泻） early enough， you might like to try taking about 10 or 15 pancreatic digestive enzymes， which can digest the multiplying bacteria before they take over.

（5） Taking a teaspoon of silicol gel can also help. This lines the stomach and upper intestinal area and binds with bacteria and viruses， allowing them to be safely passed out of the gut. When you pack，include grapefit-it-seed extract， which is an excellent all-round anti-bacterial， anti- parasitic，anti-viral （抗毒的） and anti-fungal （杀菌的） agent.

（6） Your flight can also be made more pleasant. Peppermint oil and ginger capsules （胶囊） ward off motion sickness， but a more delicious option is to eat crystallized ginger. If you tend to get ear-ache on take-off and landing， you can use special ear plugs with filler that slows down the rate of change in air pressure.

（7） The greatest concern is "economy class syndrome"， the popular name for deep-vein thrombosis （血栓症）， which can lead to blood clots traveling from the legs to the lungs， heart or brain. To reduce this， you need a couple of hours to stay hydrated， and avoid alcohol.

（8） You can also reduce the severity of inflammation by taking a daily gram of vitamin C with the bioflavonoid quercetin. Vitamin C and quercetin also help to reduce prickly heat.

（9） Finally， if any adverse symptoms persist while overseas， you should see a doctor.

Medicine Award Kicks off Nobel

Prize Announcements

Two scientists who have won praise for research into the growth of cancer cells could be can-didates for the Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements.

Australian-born U. S. citizen Elizabeth Blackburn and American Carol Greider have already won a series of medical honors for their enzyme research and experts say they could be among the front-runners for a Nobel.

Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004,who shared the prizewith Richard Axel.

Among the pair&39;s possible rivals are Frenchman Pierre Chambon and Americans Ronald Evans arid Elwood Jensen, who opened up the field of studying proteins called nuclear hormone re-ceptors.

As usual, the award committee is giving no hints about who is in the running before presen-ting its decision in a news conference at Stockholm&39;s Karolinska Institute.

Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the cat-egories of medicine, physics, chemistry, literature and peace. The economics prize is technicallynot a Nobel but a 1968 creation of Sweden&39;s central bank.

Nobel left few instructions on how to select winners, but medicine winners are typically awar-ded for a specific breakthrough rather than a body of research.

Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronor (US $1.3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal for scientists.

"&39; Individual researchers probably don&39;t look at themselves as potential Nobel Prize winners when they&39;re at work," Jornvall told The Associated Press. "They get their kicks from their re-search and their interest in how life functions. "

In 2006.Blackburn, of the University of California, San Francisco, and Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize for basic medical research with Jack Szostak of Harvard Medical School. Their work set the stage for research suggesting that cancel ceils use telomerase to sustain their uncontrolled growth.

Who is NOT a likely candidate for this year‘s Nobel Prize in medicine？查看材料

A.Pierre Chambon

B.Linda Buck

C.Carol Greider

D.Elizabeth Blackburn

根据以下材料，回答题Aromatherapy （芳香疗法）（1）Aromatherapy is a form. of alternative medici

根据以下材料，回答题

Aromatherapy （芳香疗法）

（1）Aromatherapy is a form. of alternative medicine which is based on the use of very concentrated essential oils from the flowers， leaves， bark， branches or roots of plants which are considered to have healing properties. In aromatherapy these powerful oils are mixed with other oils， such as almond （杏仁） oil， or they are diluted （稀释） with water. These solutions （溶液剂） can be rubbed on the skin， sprayed in the air， or applied as a compress （敷药） .

（2） Many people have aromatherapy massages （按摩）， and depending on the treatment a person is having， the aromatherapist will massage the oil into the hands or shoulders. The massage is smooth and flowing， as it is designed to create a sense of relaxation and calm. The sessions are tailored to the individual"s health and mood at the time， so every session is unique.

（3） Practioners of aromatherapy believe that the aroma of the essential oils directly stimulates the brain or that the oils are absorbed through the skin into the bloodstream， where they can affect the whole body and promote healing. Other claims in support of aromatherapy are that it aids digestion， improves the function of respiratory system， reduces muscular aches and pains， and promotes muscle relaxation and tone. It has also been argued that aromatherapy can improve circulation， lower blood pressure， and help combat insomnia （失眠） and other stress-related disorders such as tension headaches， anxiety， and mild depression.

（4） However， while aromatherapy may have real effects that promote a sense of well-being， some traditional medicine practitioners remain doubtful about its powers. While research has confirmed that aromatherapy does have some positive short-term effects on most people， it also suggests that aromatherapy is not an actual science or medicine that should be used to treat illness. Furthermore， not all aromatherapy is considered beneficial to health. There are precautions which should be taken before having aromatherapy because some oils can have negative effects on people with certain medical conditions. The study of aromatherapy is relatively new and unexplored. More research needs to be conducted to make scientific conclusions about its use and effects.

Medical Education

In 18th century colonial America, those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London, Paris and Edinburgh. Medicine was first taught formally by specialists at the University of Pennsylvania, beginning in 1765, and in 1767 at King&39;s College (now Columbia University), the first institution in the colonies to give the degree of doctor of medicine.

Following the American Revolution, the Columbia medical faculty (formerly of King&39;s College) was combined with the College of Physicians and Surgeons, chartered in 1809, which survives as a division of Columbia University.

In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital. The growth of medical schools attached with established institutions of learning went together with the development of proprietary (私营的) schools of medicine run for personal profit, most of which had 10W standards and poor facilities. In 1910 Abraham Flexner, the American education reformer, wrote Medical Education in the United States and Canada, exposing the poor conditions of most proprietary schools. Subsequently, the American Medical Association(AMA) and the Association of American Medical Colleges (AAMC) laid down standards for course content, qualifications of teachers, laboratory facilities, connection with teaching hospitals,and licensing of medical practitioners (开业医师) that survive to this day.

By the late 1980s the U.S. and Canada had 1424 medical colleges recognized by the Liaison(联络) Committee on Medical Education to offer the M. D. degree; during the 1987-1988academic year,47,262 men and 25,686 women entered these colleges and an estimated 11,752 men and 5,958 women were graduated. Graduates, after a year of internship (实习期) , receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners.

In 18th century America， higher institutions of learning that taught medicine __________. 查看材料

A.did not exist

B.were few in number

C.were better than those in Europe

D.were known for their teaching hospitals
