How can you tell the difference between a problem that will go away on its own and one that should be attended to as soon as possible Here are six symptoms that you should call your doctor about. 1. Persistent Headaches Everybody gets headaches now and then. If you’’ve had the same pattern of headaches for years, chances are that it’’s going to continue that way for years more. But if your headaches are so severe that you miss work or social gatherings, or if over-the-counter painkillers don’’t help, see your doctor. There are new treatments now that work well, even for disabling migraines (偏头痛). If you have an unfamiliar type of headache that’’s persisted for three days or longer and is associated with vomiting or visual changes, it could indicate an abnormality in or near the brain, such as a blood clot. If you have an unremitting (不间断的) headache on only one side of your head, near the temple or above the ear, it may be a condition called temporal arthritis (颞动脉炎). It can be cured with cortisone (可的松) or steroids (类固醇) , but, left untreated, it can lead to blindness. The most important thing to remember: Any new or extremely painful headache should prompt you to call your doctor. 2. Chest Pain Colds and respiratory infections often result in inflammation of the cartilage (软骨) next to the ribs, which can cause chest pain. Pneumonia or pleurisy (胸膜炎), an inflammation of the lining of the lungs, can also lead to chest or rib pain. So if your chest hurts, don’’t panic, but do look into it. Chest pain can indicate something as simple as a gas bubble in the stomach, or it could be a heart attack. Sometimes it’’s hard to distinguish between the two. When a nerve near the heart (called the vagus nerve) becomes irritated because of a heart attack, it can cause stomach symptoms. If the pain goes away with an antacid (抗酸剂), it’’s less likely to be related to the heart. Most times, it’’s probably not a heart attack, but if dull, pressure-like chest pain comes on for no reason, call an ambulance and get to an emergency room. Why an ambulance rather than your neighbor For two reasons: Many ambulances now come equipped with sophisticated monitoring equipment, and emergency personnel are trained to administer necessary medication at a time when every minute counts. A number of doctors also recommend that you take an aspirin to protect your heart from a blood clot while the ambulance is on its way. 3. Abdominal (腹部的) Pain All of us suffer abdominal pains occasionally, and their causes are many. In fact, there are entire medical textbooks on how to evaluate this particular type of pain. In most cases, it’’s something that can be easily cured. Abdominal pain that occurs before meals and is relieved by food can indicate an ulcer (溃疡). Treatment is generally simple, so why suffer If the pain occurs when you eat, it might mean gastritis (an inflamed stomach) , or a problem with the gallbladder (胆囊) or pancreas (胰腺). The pain related to each of these conditions has somewhat different characteristics, so your doctor will probably ask such questions as where the pain radiates, what eases it, what makes it feel worse, and whether the pain comes on when you lie down. More serious causes of abdominal pain can include problems with blood vessels that nourish the intestines (肠) or with the aorta (the artery that distributes oxygen-containing blood from the heart to other parts of the body), gallstones, obstruction of the intestine, an infection, or cancer. Whatever the possible cause, have the pain checked out. 4. Bruising and Bleeding If you bump into something and get a bruise, it generally turns blue-purple over a day or two and then slowly fades to yellow over the course of another four or five days. That’’s normal and is nothing to be concerned about. In addition, many of us develop mysterious bruises from time to time and don’’t remember bumping into anything. But if you develop spontaneous recurrent bruises in places that aren’’t prone to being bumped, it could signify a disorder of blood clotting (凝结). It could also be because you’’re taking medications that predispose you to bruising, such as wayfaring (徒步), which is a blood thinner, or aspirin. If you cut yourself or brush your teeth too vigorously, you’’ll start to bleed. Put an antiseptic (抗菌剂) on the cut or ease the pressure on your toothbrush and you’’ll be fine. However, if you notice any rectal (直肠的) bleeding, any vaginal bleeding after menopause (更年期), any blood in your urine, or any blood when you vomit or cough, make an appointment with your doctor to find out the cause. It might be a simple problem, or it might possibly be serious. 5. Breathing Problems If you have a cold, sinus (静脉窦) problem, or allergies that cause nasal congestion, you may find it difficult to breathe. A cold will generally clear up on its own in a week, and you’’ll be back to normal in short order. But if a sinus problem or allergies continue to distress you, call your doctor for an appointment. A simple medication will often do me trick, and you’’ll be smelling the roses soon. People who are out of shape certainly find strenuous activity more difficult than those who exercise regularly, so difficulty breathing on exertion can be a sign that it’’s time to start exercising. But it could also raise a red flag that indicates lung problems, heart problems, asthma, or even anemia. Also, if you become short of breath when you’’re lying down and have to prop yourself up on two or three pillows to sleep comfortably, it might signal heart failure. Call your doctor. 6. Sadness I don’’t know a single person who hasn’’t felt blue or sad from time to time. These feelings are a normal component of human emotion and deserve attention and recognition, but not necessarily medical intervention. So if you’’re blue because a friend moved away or someone close to you is ill, that’’s unfortunate, but it’’s not a reason to call your doctor. If you feel sad or irritable most of the day for at least two weeks, however, and you take less interest in activities that once gave you pleasure, then it’’s time to seek help. You could be suffering from depression, which is a painful and disabling problem. Other signs of depression include crying spells for no apparent reason, unexplained aches and pains that won’’t go away, difficulty in making decisions, an inability to concentrate, and a feeling that the future looks grim. Many people believe that persistent feelings of hopelessness are part of aging. That’’s not true. So by all means talk to your doctor. Fortunately, depression is treatable. Nobody should have to suffer from it, and nobody should have to live with it.Brain abnormality is caused by blood clot. A．YB．NC．NG

The borrowing or adding of foreign words to English was a way of expanding the language. Britain had colonies in Africa, Asia, and America. These colonies are now independent, but English is still one of the languages spoken there. And the English language grew as words from native languages were added. For example, the word "shampoo" for hair soap comes from India. "Banana" is believed to be from Africa.English speakers also continue to invent new words by linking old words together. A good example is the words "motor" and "hotel". Many years ago, someone linked them together into the word "motel". A motel is a small hotel near a road where people traveling in cars can stay for the night. Other words come from the first letters of names of groups or devices. A device to find objects that cannot be seen called Radio Detecting and Ranging became "radar".People often ask how many words exist in English. Well, no one really knows. The Oxford English Dictionary lists about 615,000 words. Yet the many scientific words not in the dictionary could increase the number to almost one million. And experts are never really sure about how to count English words.What is demonstrated by the example of words "motel" and "radar"?A. English speakers keep inventing new words now and then.B. English could link old words to expand its vocabulary.C. English has become a common language.D. English has borrowed many words.

Is It Worth Eating an Organic Diet? [A] Sales of organic food have been rising steadily over the past decade, reaching almost 30billion in 2011, or 4.2% of all U.S. food and beverage (饮料) sales, according to the OrganicTrade Association. Many of the consumers who purchase these products say paying morefor organic produce, milk and meat is a trade-off(权衡) they are willing to make in order toavoid exposure to chemical pesticides and fertilizers and milk from cows given bovine growthhormone (牛生长激素). Some experts say common sense should tell us that food grownwithout the help of synthetic chemicals is probably safer and healthier to consume than foodcontaining those substances, even in trace amounts. They believe Americans should try tosubstitute organic products for conventional ones whenever possible. [B] However, other families, especially those whose food budgets may be more limited wonder iforganic food is really worth its hefty (异常大的) price tag. Other experts point out that thereisn't enough scientific evidence to say for sure that eating organic food leads to better health.As such, they say the most important dietary advice they can give Americans is to eat morefresh fruit and vegetables and less processed food. [C] Alex Leo, associate professor of environmental exposure biology at the Harvard School of PublicHealth, argues for eating more organic food. Janet H. Silverstein, a professor of endocrinology (内分泌学) at the University of Florida and a co-author of an American Association of Pediatrics (儿科学) study on the health benefits of an organic diet, takes the skeptic's (怀疑者的) view. So far,researchers haven't been able to provide them with a definitive answer. [D] Is there definitive scientific proof that an organic diet is healthier? "Not yet," said Leo. Robustscientific studies comparing food grown organically and food grown conventionally don'texist, thanks to a lack of funding for this kind of research. "The lack of definitive evidencecombined with the higher price of organic food has given skeptics a golden opportunity toargue that organic isn't worth the cost and effort," he added. [E] While studies in recent years have delivered a decidedly mixed message about thehealthfulness of organic food, those on both sides of the debate generally agree that organicproduce typically contains fewer pesticides than conventional produce, and that people maybe able to reduce or eliminate agricultural chemicals from their bodies by adopting an organicdiet. This was illustrated in a study published in the journal Environmental Health Perspectivesin 2006. That study, which was led by Leo, showed that within five days of substituting mostlyorganic produce for conventional produce in children's diets, pesticides disappeared from thechildren's urine ( 尿液). [F] Many say the pesticides found in our food are nothing to fear because the levels fall well belowfederal safety guidelines and thus aren't dangerous. Similarly, they say the bovine growthhormone used to increase cows' milk yield is perfectly safe. But federal guidelines don't take intoaccount what effect repeated exposure to low levels of chemicals might have on humans overtime. And many pesticides were eventually banned or restricted by the federal government afteryears of use when they were discovered to be harmful to the environment or human health. [G] Pesticides, in particular, are made to kill organisms, and the President's Cancer Panel in 2010made clear that it sees them as a threat, advising Americans to "reduce their cancer risks bychoosing, to the extent possible, food grown without pesticides or chemical fertilizers." [H] Recent field studies showed that organic produce, such as strawberries, leafy vegetables andwheat, not only tastes better but contains much higher levels of phenolic acids (酚酸) thanconventional produce. Phenolic acids can prevent cellular damage, and offer some protectionagainst oxidative stress ( 氧化应激), inflammation (炎症) and cancer. [I] Yes, organic food typically costs more and can be harder to find than traditional food, but onecould argue that the price of conventional food is artificially low because of all the subsidiesthat organic farmers don't get and that the government could do more to help organic farmerslower their costs. Nevertheless, when bought in season, organic produce is often comparable inprice to conventional produce. [J] A good strategy for consumers on limited budgets is to buy the organic versions of foods on theEnvironmental Working Group's "Dirty Dozen" list, as they typically contain the most pesticides.Or, consumers could focus on buying the organic versions of the foods they eat most. Knowingthat we could reduce our exposure to pesticides and increase our exposure to antioxidants ( 抗氧化剂 ) by eating organic food, it makes great common sense to consume more of it. [K] Organic food is more expensive than conventional offerings, which could make it costprohibitive for families on limited food budgets. Given the lack of data showing that organicfood leads to better health, it would be counterproductive to encourage people to adopt anorganic diet if they end up buying less produce as a result. If families can afford to buyorganic and still put a good amount of healthy food on the table, then the decision aboutwhether to spend the extra money on organic produce, milk and meat should be based on asolid understanding of what we do and don't know about the benefits. [L] It is difficult to compare the nutritional value of organic versus conventional food because thesoil, climate, timing of harvest, and storage conditions all affect the composition of produce.Still, published studies have found no significant differences in nutritional quality betweenorganic and nonorganic produce or milk. Similarly, there is no evidence that giving bovinegrowth hormone (BGH. to cows changes the composition of milk or affects human health.BGH is inactive in humans and degrades in the acidic environment of the stomach. As forpesticide exposure, the U.S. in 1996 established maximum permissible levels for pesticideresidues (残留) in food to ensure food safety. Many studies have shown that pesticides levels in conventional produce fall well below those guidelines. [M] While it's true that organic fruits and vegetables in general contain fewer traces of these chemicals,we can't draw conclusions about what that means for health as there haven't been any long-termstudies comparing the relationship between exposure to pesticides from organic versus nonorganicfoods and adverse health outcomes. It may seem like "common sense" to reduce exposure to thesechemicals, but there are currently no good evidence-based studies to answer the question. [N] While awaiting definitive studies, families on limited budgets who are concerned aboutpesticide exposure can refer to the Environmental Working Group's list of the "Dirty Dozen,"those foods with the highest pesticide residues, and the "Clean 15", the foods with the lowestpesticide concentrations. A good strategy would be to focus on buying organic versions of thefoods on the "Dirty Dozen" listing. [O] We would like to think that organic food is grown locally, put in a wheelbarrow (独轮手推车) and brought directly to our homes. However, much of it comes from countries whereregulations might not be as tightly enforced as in the U.S., and labeling of the foods mightbe misleading. And just because food is labeled organic doesn't mean it is completely free ofpesticides. Contamination can occur from soil and ground water containing previously usedchemicals, or during transport, processing and storage. Organochlorine insecticides (有机氯杀虫剂) were recently found in organically grown root crops and tomatoes even though thesepesticides haven't been used for 20 years.1.[选词填空]The Environmental Working Group's lists tell people which food is with the most pesticideresidues and which is with the least.2.[选词填空] Food marked organic may contain pesticides as well.3.[选词填空]Many factors make it hard to tell the differences between organic food and traditional food interms of nutrition.4.[选词填空]Federal guidelines do not consider the impact of constant exposure to small amounts ofchemicals on human health.5.[选词填空]Americans, especially those from less wealthy families, are suggested by some experts to eatmore fresh fruit and vegetables rather than processed foods.6.[选词填空]Janet H. Silverstein is skeptical about the idea of eating more organic food.7.[选词填空]Consensus is reached that agricultural chemicals may be able to reduced or eliminated from ourbodies by adopting an organic diet.8.[选词填空]If limited in food budget, people can buy seasonal organic vegetables which match withconventional produce in price.9.[选词填空]People can only afford less food should not be encouraged to adopt an organic diet, especiallywhen there is no solid evidence that proves organic food is better for our health.10.[选词填空]Some experts argue conventional food should be replaced by organic ones, since it is ourcommon sense that food with even the smallest amount of synthetic chemicals is moredangerous and unhealthy than food without those substances.
