Which foods should be eaten to keep us healthy?Let us look at some important vitamins for these answers.Vitamin A helps prevent skin and other tissues from becoming dry.People who do not get enough vitamin A cannot see well in darkness.Vitamin A is found in fish liver oil.It also is in the yellow part of eggs.Sweet potatoes,carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.Vitamin B-one changes starchy（含淀粉的）foods into energy. It also helps the heart and nervous system work smoothly.Without it,we would be weak and would not grow.Vitamin B-one is found not just in whole grains like brown rice,but also in other foods.These include beans and peas,nuts,and meat and fish.Vitamin B-twelve is needed so folic acid（叶酸）can do its work. Together, they help produce red blood cells.Vitamin B-twelve is found naturally in foods such as eggs,meat,fish and milk products.Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy.Vitamin B-twelve is found in green leafy vegetables and other foods,like legumes and citrus fruits.In some countries,it is added to products like bread.Vitamin C is needed for strong bones and teeth,and for healthy blood passages.It also helps wounds heal quickly.The body stores little vitamin C.So we must get it every day in foods such as citrus（柑橘类）fruits,tomatoes and uncooked cabbage.Vitamin D increases levels of the element calcium in the blood.Calcium is needed for nerve and muscle cells to work normally.It also is needed to build strong bones.Ultraviolet light from the sun changes a substance in the skin into vitamin D.Fish liver oil also contains vitamin D.Vitamin K is needed for healthy blood.It thickens the blood around a cut to stop bleeding. Vitamin K can be found in pork products,liver and in vegetables like cabbage,kale and spinach. In most countries,vitamin B-twelve is added to products like bread.A:Right B:Wrong C:Not mentioned

U.S.Eats Too Much SaltPeople in the United States consume more than twice the recommended amount of salt,raising their risk for high blood pressure,heart attacks and strokes,government health experts said on Thursday.They found nearly 70 percent of U.S.adults are in high-risk groups that would benefit from a lower-salt diet of no more than 1,500 mg per day,yet most consume close to 3,500 mg per day.“It's important for people to eat less salt.People who adopt a heart-healthy eating pattern that includes a diet low in sodium and rich in potassium and calcium can improve their blood pressure,”Dr.Darwin Labarthe of the Centers for Disease Control and Prevention said in a statement."People need to know their recommended daily sodium limit and take action to reduce sodium intake,"Labarthe said.The study in CDC's weekly report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are black or over the age of 40-which are considered highrisk groups.Yet studies show most people in the United States eat 3,436 mg of sodium per day,according to a 2005-2006 CDC estimate.Most of the sodium eaten comes from packaged,processed and restaurant foods.The CDC said it will join other agencies in the Health and Human Services department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply.Nationwide,16 million men and women have heart disease and 5.8 million are estimated to have had a stroke.Cutting salt consumption can reduce these risks,the CDC said.Packaged,processed and restaurant foods are known to be______.A:cheapB:tastyC:rich in saltD:healthy

Osteoporosis and MenMention the word osteoporosis in the manly world of testosterone（皋丸素）, professional basketball and the XFL（美国最新的职业足球联合会）,and you're likely to get a wave of the hand and a dismissive（轻蔑的）"That's a woman's disease."Not so. More than 2 million American men have been found to have the thinning bones and skeletal（骨骼的）weakness of osteoporosis（骨质疏松症）,and an additional 3 million are at an increased risk of developing them.It's true that osteoporosis strikes women with much greater frequency than men一in some studies as much as four to six times as often.But that's no reason to brush it off as "their"disease.It's a mere stroke of gender luck that men's bones tend to grow larger, stronger and denser. Also paying dividends are those sports that boys(and,increasingly, girls)play as children一running up and down basketbal}courts,soccer and baseball fields. As it happens,physical activity is one of the more important ways to increase bone density and protect bone health.But even the most active men cannot ignore certain facts of life.All of us build up our bones during the first three decades of life,typically reaching peak bone mass in the early 30s.Around the age of 35,we begin gradually to lose some of this bone mass.Women ultimately give up between 30%to 50%.Though mass loss in men is lower,it still makes us vulnerable to back pains and bone fractures.In fact,this year alone American men will suffer as many as half a million osteoporosis-related breaks,mostly in the spine,hip and wrist.These are not only painful;thousands die each year from fracture-related complications.For many of us,however,there's still time.of all the side effects of aging, osteoporosis is one of the more preventable,through diet,exercise and changes in lifestyle.The two key nutritional substances for bone health are calcium（钙）,which makes bones stronger, and vitamin D,which helps the body absorb the calcium.Exercising is also important,with emphasis on weight-bearing activities in which bones and muscles work against gravity.Lifting weights and working out on resistance machines can help preserve bone density.Be careful about what's in your medicine cabinet.Prolonged use of some medications, such as steroids（类固醇）,can weaken your bones. Smoking and drinking are both bad for bones,as is prolonged weightlessness,for anybody who plans to work on the space station.Men are justified in thinking that osteoporosis is a woman's disease.A:Right B:Wrong C:Not mentioned

第二篇Superconducting Ceramic（陶瓷）An underaround revolution beqins this winter. With the flip（轻击）of a switch, 30,000 homes in one part of Detroit will soon become the first in the country to receive electricity transmitted by ice-cold high-performance cables.Other American cities are expected to follow Detroit's example in the years ahead,which could conserve enormousamounts of rower.The new electrical cables at the Frisbie power station in Detroit are revolutionary because they are made of superconductors.A superconductor is a material that transmits electricity with little or no resistance.Resistance is the degree to which a substance resists electric current.All common electrical conductors have a certain amount of electrical resistance.They convert at least some of the electrical energy passing through them into waste heat.Superconductors don't.No one understands how superconductivity works.It just does.Making superconductors isn't easy.A superconducting material has to be cooled to an extremely low temperature to lose its resistance.The first superconductors,made more than 50 years ago,had to be cooled to -263 degrees Celsius before they lost their resistance.Newer superconducting materials lose their resistance at-143 degrees Celsius.The superconductors cable installed at the Frisbie station is made of a ceramic material that contains copper,oxygen,bismuth（秘）,strontium（锶）and calcium (钙）.A ceramic is a hard,strong compound made from clay or minerals.The superconducting ceramic has been fashioned into a tape that is wrapped lengthwise around a long tube filled with liquid nitrogen.Liquid nitrogen is supercold and lowers the temperature of the ceramic tape to the point where it conveys electricity with zero resistance.The United States loses an enormous amount of electricity each year to resistance. Because cooled superconductors have no resistance,they waste much less power. Other cities are watching the Frisbie experiment in the hope that they might switch to superconducting cable and conserve power,too.What element enables the ceramic tape to lower its temperature?A:Copper. B:Liquid nitrogen.C:Clay. D:Calcium.

问答题Dental Health Decay is not the only disease that can cause tooth loss. Another serious disease affects the gums, the tissue that surrounds the teeth. It is also caused by bacteria. If the bacteria are not removed every day, they form a substance that stays on the teeth. The substance is known as plaque. At first, the gums appear to be swollen, and may bleed when the teeth are brushed. This can lead to serious infection of the tissue around the teeth. The infection may damage the bone that supports the teeth and cause tooth loss and other health problems. Studies have found that people with severe gum disease have an increased risk of developing heart disease, diabetes and stroke. Gum disease can be treated by a special dentist called a periodontist. Periodontists are trained to repair the gum areas that have been damaged. This can be painful and costly. Dental health experts say the best thing to do is to stop gum disease before it starts. The way to do this is to clean the teeth every day. People also should use dental floss to remove plaque from between the teeth. Most experts also agree that another way to prevent tooth and gum problems is to eat foods high in calcium and vitamins and low in sugar. Scientists continue to develop better dental treatments and equipment. Improved technology may change the way people receive dental treatment in the future. For example, dentists are now suing laser light to treat diseased gums and teeth. Dentists use computer technology to help them repair damaged teeth. Researchers have developed improved methods to repair bone that supports the teeth. And genetic research is expected to develop tests that will show the presence of disease causing bacteria in the mouth. Such increased knowledge about dental diseases and ways to prevent them has improved the health of many people. Yet problems remain in some areas. In industrial countries, minorities and other groups have a high level of untreated dental disease. In developing countries, many areas do not have even emergency care services. The World Health Organization says people in countries in Africa have the most tooth and gum problems. World Health Organization experts say the dental health situation is different for almost every country in the world. As a result, it has developed oral health programs separately for each area. The WHO oral health program is mainly for people living in poor areas. It provides them with information about mouth diseases and health care. It also studies preventive programs using fluoride in water, salt, mild and toothpaste. And it explores ways to include dental health in national health care systems. Many governments and other organizations provide help, so people can get needed dental health services. But dental health professionals say people should take good care of their teeth and gums. They say people should keep their teeth as clean as possible. They should eat foods high in calcium and fiber. These include milk products, whole grain breads and cereals, vegetables, fruits, beans and nuts. Recent studies have shown that eating nuts can help slow the production of plaque on the teeth. Experts say these activities will help everyone improve their dental health throughout their lives.
