回答题With so many of the deaths each year from around the world directly related to poor

health choices we make．world health leaders have set a goal of lowering the number of preventable deaths by 25％from 2010 rates by 2025．That would save 37 million lives over 15 years．Reporting in thejournal Lancet，public health experts note that the ways to prevent those deaths area’t surprising．But acting on those strategies will take individual and political will．Here’s how the experts hope to do it． Not smoke．The UN General Assembly set a target of cutting smoking around the world by 30%by 2025．Already，higher-income nations that already adopted smoking bans in public places and instituted tobacco taxes have seen drops in smoking rates，however，residents in lower-income nations continue to light up at high rates． Limit excessive drinking．While moderate amounts of alcohol have been linked to some health benefits， overindulging can increase the risk of certain cancers and liver disease，as well as contribute to high blood pressure．Educating people about the risks of excessive drinking，as well as instituting taxes on alcoholic products，has been somewhat successful in curbing（遏制）abuse． Cut back on salt．High sodium （钠）diets can increase blood pressure and contribute to heart disease and stroke，and in many developed countries，people eat several times the amount the salt their bodies need．In the U．S．，the average American consumes about 800mg more salt every day than health experts consider acceptable．Promoting alternatives，such as the citric acid in lemons，to satisfy the need for salt， Call help to bring sodiunl consumption down． Get blood pressure under control．Lack of exercise and high sodium diets contribute to hypertension（高血压），and uncontrolled high blood pressure can lead to stroke and heart disease．Monitoring blood pressure with regular screenings，and treating elevated levels with changes in diet and exercise，or medications if necessary，are the most effective ways to address this risk factor． Address diabetes．Closely tied to the obesity epidemic（肥胖病）that now affects developing as well as developed nations，diabetes can increase the risk of heart disease，kidney disease and other conditions that can shorten life．Studies show that lifestyle. changes incorporating healthy diets low in sugar and phy’sical activity call be as effective as medications in keeping blood sugar levels in check．

听力原文：Why are college students so prone to sleep deprivation？ The problem often begins

听力原文： Why are college students so prone to sleep deprivation？ The problem often begins during the teen years. Most high school kids admit that they are often sleepy and 15 percent admit that they fall asleep in class.

Lack of sleep causes many problems, not the least of which is the difficulty it adds to learning. It's also detrimental to the immune system and motor skills. Students (and everyone else) need at least eight hours of sleep to maintain optimum health and learning capabilities. Yet, with the pressure of school, family and social life, few students are sleeping near the required amount.

College life only escalates the problem. Added to the above activities are more hours needed for studies. Some students also hold down a part time job to help defray college expenses. Some students are married and trying to support a family. Because of all these pressures there is also an increase in stress. Stress can lead to insomnia and even more lost sleep.

With the approach of finals, the problem can only grow worse. Students force themselves to stay awake to study. It's called cramming for exams, and it can eat away at sleep hours already far too meager. Too many nights of forced wakefulness can eventually lead to a case of full-blown insomnia and other sleep abnormalities.

(30)

A．Eating disorders, low immunity and poor motor skills.

B．Difficulty concentrating, poor motor skills, divorce.

C．Low immunity, poor self esteem, eating disorders.

D．Poor motor skills, difficulty concentrating, low immunity.

Hepatitis is a disease characterized by inflammation of and injury to the liver. The di

sease has many causes, including misuse of alcohol and drugs, but viruses are the most common cause. Researchers estimate that more than 300,000 cases of viral hepatitis occur each year in the United States.

2. Symptoms of viral hepatitis appear from two weeks to six months after exposure to the virus. The first symptoms are usually fatigue, poor appetite, and nausea. Pain in the abdomen above the liver and a slight fever are also common. After a few days, the person's urine becomes dark and jaundice appears. The jaundice and dark urine indicate the liver is not working properly.

3. Symptoms of viral hepatitis generally last two to six weeks. Severe cases can lead to liver failure and death. But most patients-even those with severe hepatitis-eventually recover completely. In some patients, the disease becomes persistent and is called chronic hepatitis. People with chronic hepatitis may experience mild, vague symptoms of fatigue and poor appetite.

4. There are five types of viral hepatitis. Hepatitis A is a highly contagious disease, but it is rarely fatal. It is also called infectious hepatitis. Hepatitis A is extremely common in developing nations. Outbreaks often occur due to unsanitary conditions, such as contamination of food or the water supply.

5. Hepatitis B is the best-known form. of viral hepatitis. It can be severe and often develops into chronic hepatitis. Hepatitis B is spread by close personal or sexual contact with an infected person, or by exposure to infected blood.

6. Hepatitis C is usually spread by exposure to infected blood. It is the most common cause of transfusion-related hepatitis. It is also a common cause of chronic hepatitis. Hepatitis D is the most serious and also the rarest form. of viral hepatitis. It only infects people who also have hepatitis B. Many cases of hepatitis D are fatal, and most commonly occur among intravenous drug users, who can be infected by sharing hypodermic needles. Hepatitis E often occurs in epidemics that can be linked to poor hygiene and contaminated water. It is particularly likely to lead to serious illness in pregnant women. The disease has been reported almost exclusively in developing countries.

A. Scientists do not know exactly why Hepatitis develops.

B. Hepatitis A often breaks out in filthy places where food and water are easily contaminated.

C. Symptoms of hepatitis include languor, loss of appetite, distress of the stomach, and yellowness of urine.

D. Hepatitis B is the best-known form. of viral hepatitis.

E. The chronic hepatitis lasts a long time and is most likely to recur.

F. People should pay attention to public environment for the preservation of health.

Systematic efforts at national nutrition planning in developing countries go back barely

a decade. During that brief time there has been considerate progress in establishing the extent and causes of【M1】______ malnutrition and what can be done to reduce it. Ten years ago, malnutrition was often thought of to reflect【M2】______ primarily a shortage of protein(and in some cases, vitamins or minerals). Most nutrition programs concentrated on providing high-protein food to children, usually in schools. However, emphasis【M3】______ today is similar. There is now a wide measure of agreement on several broad propositions. Serious and extensive nutritional deficiencies occur in virtually all developed countries, though they are worst in【M4】______ low-income countries. They are usually caused by undernourishment, not by an imbalance of calories and protein. There may often be【M5】______ shortage of specific micronutrients and of protein, especially with【M6】______ young children. But giving the typical composition of the diets of the poor, to【M7】______ the extent that calorie requirements(as estimated by the FAO and the WHO)are met, it is unlikely that other nutritional needs will also be【M8】______ satisfied. Malnutrition affects old and young, male and female, urban and rural dwellers; particularly prevalent among children under five, it reduces their resistance of diseases and is a major cause of their【M9】______ death. In many societies, girls suffer more than boys. Malnutrition is largely a reflection of poverty; people do not have enough ample【M10】______ income for food. On the condition of the slow income growth that is likely for poverty-struck people in the foreseeable future, a large number of people will remain malnourished for decades to come.

听力原文：A new international study shows that six people die every minute from smoking. Th

听力原文： A new international study shows that six people die every minute from smoking. This study shocked most people because it means 3 million deaths around the world every year. If the present rate of smoking continues, the number of deaths each year from smoking could rise to 10 million by the year 2050. This news has worried the most people in the developed countries, especially those smokers.

The study also shows that smoking is the main cause of the death in industrial countries, and most of the smoking deaths have happened to men, especially in developing countries. That means more people smoke in the poor areas than in the rich areas and more people died in the poor countries than in the wealthy countries.

In addition, the study indicates that smoking may also cause lung cancer to those adults. It may lead to cancer of the mouth and other parts of body. Smokers are more likely than nonsmokers to suffer from heart disease. Therefore, experts advise the people to stop smoking completely so that they can reduce their chance of dying early.

(30)

A．3 million smokers increase every year.

B．3 million people get lung cancer every year.

C．3 million cigarettes ate produced every year.

D．3 million people die from smoking every year.
