U.S.Eats Too Much Salt
People 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.

第一篇Heat and HealthExtremely hot weather is common in many parts of the world.Although hot weather just makes most people hot,it can cause medical problems and death.Health experts say that since the year 1900,extremely hot weather has killed more people in the United States than any other natural event.One year一the unusually hot summer of 1980一heat caused about 1,700 deaths in the United States.In 1995,more than 600 people died in a similar heat wave in one city一Chicago.To measure extreme heat,government weather experts have developed the Mean Heat Index.It measures the average of how hot it is felt all day on an extremely hot day.Experts say it is the total heat of a hot day or several hot days that can affect health.Several hot days are considered a heat wave.Experts say heat waves often become deadly when the nighttime temperature does not drop much from the highest daytime temperature.The most common medical problem caused by hot weather is heat stress.It is also least severe.For most people,the only result of heat stress is muscle pain.The pain is a warning that the body is becoming too hot. Doctors say drinking water will help the pain disappear after the body again has the right amounts of water and salt.For some people, however,the result is much more serious.For example,doctors say some people face a greatly increased danger from heat stress.These people have a weak or damaged heart,high blood pressure,or other problems of the blood system.Severe heat can help cause a heart attack or stroke.Health experts say this is the most common cause of death linked to hot weather. A heat wave is a period of time during whichA:the weather is much better than usual.B:the nights are much longer than usual.C:the weather is much hotter than usual.D:the days are much longer than usual.

第三篇A New Cause of SufferingA conference on obesity（肥胖症）was recently held in Vienna. Two thousand experts from more than fifty countries attended the conference.According to statistics,1.2 billion people worldwide are overweight,and 250 million are too fat.Obesity is rapidly becoming a new cause of suffering.Professor Friedrich Hopichler of Salzberg said:"We are living in the new age but with the metabolism（新陈代谢）of a stone-age man. I have just been to the United States. It is really terrible. A pizza（比萨饼）shop is appearing on every corner. We have been occuoied by fast food and Coca-Cola-ization."Many of the experts stressed that obesity was a potential killer.Hopicnier saia: "Eighty per cent of all diabetics（糖尿病人）are too fat,also fifty per cent of all patients with high blood pressure and fifty per cent with fatty（脂肪的）tissue complaints. Ten per cent more weight means thirteen per cent more risk of heart disease.Reducing one's weight by ten oer cent leads to thirteen per cent lower blood pressure."Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs,"The health insurance pays for surgery(such as reducing the size of the stomach ) when the body-mass index（身体质量指数）is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.60 meters.One should start earlier."Toplak said that prevention should begin in school.“Child obesity has a close relation with the time which children spend in front of TV sets." According to the passage,obesity is associated with all the following EXCEPTA:high blood pressure. B:fatty tissue complaints.C:stomachache. D:heart disease.

Hypertension Drugs Found to Cut Risk of StrokeAustralian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of patients suffering a repeat stroke by more than a third.This is the result of their research.The research, presented at a medical conference in Italy over the weekend,has been valued highly as a major breakthrough in stroke prevention.Strokes kill 5 million people a year,and more than 15 million suffer non-fatal strokes that often leave them with useless limbs,slurred speech and other serious disabilities.One in five stroke survivors goes on to have a second,often fatal,stroke within five years of the first.An international six-year study of 6,100 patients directed from Sydney University found that by taking two blood pressure-lowering drugs,the risk of secondary strokes can be reduced by up to 40 percent.Even taking one of the commonly available drugs can cut the risk by a third,the study said.The drugs are the diuretic indapamide ( 吲达帕胺）and the ACE inhibitor perindopril , better known by its brand name Cover- syl.The combination was effective even in patients who did not have high blood pressure,the researchers said.They even found that the risk of another stroke could be cut by three quarters among the one-in-ten pa- tients who had suffered a cerebral hemorrhage（出血）, the worst type of stroke , where there is direct bleeding into the brain.Stephen McMahon,who presented the research at the Milan congress of the European Society of Hypertension,said about 50 million people were alive who had suffered at least one stroke."If most of those patients were able to get access to this treatment,it would result in maybe the avoidance of half a million strokes a year,"the professor told Australia's ABC Radio.McMahon said doctors had long known that lowering the blood pressure of those with hypertension could help prevent strokes."What we have shown for the first time is that it does not really matter what your blood pressure is;if you have had a stroke,then lowering blood pressure will produce large benefits,to begin with-even for people whose blood pressure is average or below average,"he said.McMahon said the Milan gathering had heralded the research as a"major breakthrough in the care of patients with strokes-perhaps the biggest step forward that we have made in the last couple of decades."What patients among those who have a stroke will benefit greatly from taking blood pressure-lowering drugs?A:Those whose blood pressure is high.B:Those whose blood pressure is average.C:Those whose blood pressure is below average.D:All of the above.

Hypertension Drugs Found to Cut Risk of StrokeAustralian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of patients suffering a repeat stroke by more than a third.This is the result of their research.The research, presented at a medical conference in Italy over the weekend,has been valued highly as a major breakthrough in stroke prevention.Strokes kill 5 million people a year,and more than 15 million suffer non-fatal strokes that often leave them with useless limbs,slurred speech and other serious disabilities.One in five stroke survivors goes on to have a second,often fatal,stroke within five years of the first.An international six-year study of 6,100 patients directed from Sydney University found that by taking two blood pressure-lowering drugs,the risk of secondary strokes can be reduced by up to 40 percent.Even taking one of the commonly available drugs can cut the risk by a third,the study said.The drugs are the diuretic indapamide ( 吲达帕胺）and the ACE inhibitor perindopril , better known by its brand name Cover- syl.The combination was effective even in patients who did not have high blood pressure,the researchers said.They even found that the risk of another stroke could be cut by three quarters among the one-in-ten pa- tients who had suffered a cerebral hemorrhage（出血）, the worst type of stroke , where there is direct bleeding into the brain.Stephen McMahon,who presented the research at the Milan congress of the European Society of Hypertension,said about 50 million people were alive who had suffered at least one stroke."If most of those patients were able to get access to this treatment,it would result in maybe the avoidance of half a million strokes a year,"the professor told Australia's ABC Radio.McMahon said doctors had long known that lowering the blood pressure of those with hypertension could help prevent strokes."What we have shown for the first time is that it does not really matter what your blood pressure is;if you have had a stroke,then lowering blood pressure will produce large benefits,to begin with-even for people whose blood pressure is average or below average,"he said.McMahon said the Milan gathering had heralded the research as a"major breakthrough in the care of patients with strokes-perhaps the biggest step forward that we have made in the last couple of decades."Which of the following is NOT a symptom left by strokes?A:Habitual sleeplessness.B:Losing the function of one or more extremities.C:Speaking unclearly.D:Serious disabilities such as facial paralysis.

Obesity:the Scourge of the Western WorldObesity is rapidly becoming a new scourge of the western world,delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to state-ments before the opening of the conference一of 2,000 specialists from more than 50 countries一1.2 billion people worldwide are overweight,and 250 million are obese.Professor Bernhard Ludvik of Vienna General Hospital said:“Obesity is a chronic ill-ness.In Germany,20 percent of the people are already affected,but in Japan only one per-cent.”But he said that there was hope for sufferers thanks to the new scientific discoveries and medication.Professor Friedrich Hopichler of Salzberg said:“We are living in the new age(but)with the metabolism of a stone-age man.”“I have just been to the United States.It is really terni-ble.A pizza shop is springing up on every corner. We have been overrun by fast food and Co-ca-Cola-ization.”Many of the experts stressed that obesity was a potential killer. Hopichler said:“Eighty percent of all diabetics are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease.Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs.“Though the health insurance pays for surgery( such as re-ducing the size of the stomach)when the body-mass index is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.70 meters.One should start earlier.”Ludvik said that prevention should begin in school.“Child obesity(fat deposits)correlates with the time which children spend in front of TV sets.”The consequences were only apparent later on. No more than fifteen percent of obese people lived to the average life ex-pectancy for their population group.Which of the following is most often accompanied by obesity?A:high blood pressure.B: Fatty tissue complaints.C: Diabetes.D: Stomach-ache.

资料：Why is Salt Bad for You?
FRANK LE CLAIR, a 58-year-old provincial government employee living in Winnipeg, had no idea that his blood pressure was too high. While out of town last winter, he came down with a cold and a sore throat and decided to see a local doctor.
Apart from checking his cold symptoms, the doctor also gave him a general health-check. The doctor found that Frank’s blood pressure was higher than normal and advised him to see his regular physician as soon as he got home.
Le Clair’s physician referred him to the Winnipeg Health Sciences Centre, where dietitians told him that he might be able to control his blood pressure by changing his lifestyle rather than by taking drugs. People with high blood pressure have to control or eliminate four elements: smoking, drinking, food quantities and salt. Le Clair doesn’t smoke or drink, but there were some changes he could make in the other two categories.
The most conclusive evidence so far that a high-salt diet is bad for you is the “Intersalt” study, involving 10,000 people in 32 countries. It measured the relationship between urinary sodium excretion -- a direct measure of salt consumption -- and blood pressure. The study found that populations with the lowest sodium excretion also have the lowest blood pressures.
Recent studies have shown that “salt sensitivity” is a major factor in the relationship between a high-salt diet and hypertension. And hypertension is a risk factor for two of the biggest killers in this country: coronary heart disease and stroke. Frank Le Clair’s high blood pressure was discovered by chance. There are no warning symptoms -- high blood pressure is known as the silent killer.
A high-salt intake triggers a vicious cycle. Those who are used to a lot of salt in their food find they need increasing amounts to be able to continue to taste its flavour --- the more salt they eat, the more they want. It is also an aggravating factor in osteoporosis and is closely linked to stomach cancer. A high salt intake can be dangerous for people with conditions that are aggravated by fluid retention, such as hepatitis, liver or kidney problems.
According to the passage, the major causes of death in Frank Le Clair’s country are ______.A.hypertension and high blood pressure
B.heart disease and stroke
C.liver damage and kidney problems
D.osteoporosis and stomach cancer

第一篇A New Cause of SufferingA conference on obesity（肥胖症）was recently held in Vienna. Two thousand experts from more than fifty countries attended the conference.According to statistics,1.2 billion people worldwide are overweight,and 250 million are too fat.Obesity is rapidly becoming anew cause of suffering.Professor Friedrich Hopichier of Salzberg said:"We are living in the new age but with the metabolism（新陈代谢）of a stone-age man.I have just been to the United States.It is really terrible. A pizza(比萨饼）shop is appearing on every corner. We have been occupied by fast food and Coca-Cola-ization."Many of the experts stressed that obesity was a potential killer.Hopichier said: "Eighty per cent of all diabetics（糖尿病人）are too fat,also fifty per cent of all patients with high blood pressure and fifty per cent with fatty（脂肪的）tissue complaints. Ten per cent more weight means thirteen per cent more risk of heart disease.Reducing one's weight by ten per cent leads to thirteen per cent lower blood pressure."Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs."The health insurance pays for surgery(such as reducing the size of the stomach)when the body-mass index（身体质量指数）is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.60 meters.One should start earlier."Toplak said that prevention should begin in school."Child obesity has a close relation with the time which children spend in front of TV sets." According to the article,obesity is associated with all the following EXCEPTA:high blood pressure. B:fatty tissue complaints.C:stornachache. D:heart disease.

第一篇Shift Work Link to Increased Risk of Heart ProblemsShift workers are slightly more at risk of having a heart attack or stroke than day workers,research suggests.An analysis of studies involving more than 2 million workers in the British Medical Journal said shift work can disrupt the body clock and have a negative effect on lifestyle.It has previously been linked to an increased risk of high blood pressure and diabetes.Limiting night shifts would help workers cope,experts said.The team of researchers from Canada and Norway analyzed 34 studies.In total,there were 17,359 coronary events of some kind,including cardiac arrests,6,598 heart attacks and 1,854 strokes caused by lack of blood to the brain.These events were more common in shift workers than in other people.The BMJ study calculated that shift work was linked to a 23%increased risk of heart attack,24% increased risk of coronary event and 5%increased risk of stroke.But they also said shift work was not linked to increased mortality rates from heart problems and that the relative risks associated with heart problems were"modest".Dan Hackam,associate professor at Western University,London, Ontario in Canada,said shift workers were more prone to sleeping and eating badly."Night shift workers are up all the time and they don't have a defined rest period.They are in a state of perpetual nervous system activation which is bad for things like obesity and cholesterol,"he said.The authors say that screening programs could help identify and treat risk factors for shift workers,such as high blood pressure and cholesterol levels.They add that shift workers could also be educated about what symptoms to look out for,which might indicate early heart problems.Jane White,research and information services manager at the Institution of Occupational Safety and Health,said there were complex issues surrounding shift work."It can result in disturbed appetite and digestion,reliance on sedatives and/or stimulants,as well as social and domestic problems."These can affect performance,increase the likelihood of errors and accidents at work,and even have a negative effect on health.She said the effects of shift work needed to be well managed."Avoiding permanent night shifts,limiting shifts to a maximum of 12 hours and ensuring workers have a minimum of two full nights'sleep between day and night shifts are simple,practical solutions that can help people to cope with shift work."The underlined word"disrupt"in Paragraph Two can be replaced by_______.A:preventB:controlC:cut offD:throw into disorder
