Organization are calling for everyone to practice smart flu prevention
techniques. Besides washing your hands and getting enough sleep,
here are the other 7 ways to keep your body strong and your immune
(免疫) system ready to fight infection.
Avoid Contact with Sick People
Flu virus is spread when particles (微粒) blown into the air through a cough or sneeze reach someone else’s nose. So if you’re coughing or sneezing, cover your mouth and then wash your hands, and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.Eat Immune – Boosting Foods
Keeping your body strong and ready to fight infection is important in flu prevention. Fatty foods can make you feel lazy, and make your immune system working in an inactive and compromised way. So stick with wholes grains, colorful vegetables, and vitamin – rich fruits.
Avoid Alcohol
In addition to being a mood calm and pleasant, alcohol is an immune restriction that can actually decrease your resistance to virus infections like AH1N1flu. So avoid alcohol to keep your immune system strong.
Drink Enough Water
Drink 8 – 10 glasses of water each day to wash out poisonous things from your system and maintain system in a good state,
Keep Physically Active
Adequate exercise – for example walking for 30 to 40 minutes 3 or 4 times a week – supports the immune system by increasing circulation, speeding the body’s oxygen – taking – in, taking away poisonous things through sweat, and releasing tension and stress. So get moving!
Be Careful of Surfaces
This is as much a mindfulness exercise as anything else. Be aware of what public surfaces you touch, when you’ve shaken hands with someone, or when you’re using something like a pen that others have recently used – and don’t touch your face until you’ve had a chance to wash your hands.
Know When to Get Help
AH1N1 flu can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu – like symptoms. But do consult your doctor if your symptoms are severe.

If you want to live longer and lower the risk of heart disease, a move to the mountains may help． Research by scientists in Greece shows that living in the mountains is good for the heart and longevity． People living at higher altitude have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk．"Residence in mountainous areas seems to have a "protective effect" from heart disease," said Dr Nikos Baibas of the University of Athens．He and his colleagues suspect that the increased exercise from walking up mountainous area gives the heart a good workout and enables it to cope with lower levels of oxygen．
Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years．One village was 1,000 metres above sea level and the other two were in low-lying areas．Although men and women living in the mountainous village had higher blood pressure rates and other risk factors than people in the other villages, they had a lower rate of death from heart disease and other causes after a fifteen year follow-up．"The contrast was more evident among men than among women," Baibas added in a report in the Journal of Epidemiology and Community Health．Heart disease is one of the world"s top killers．Smoking, high blood pressure, raised cholesterol levels, being overweight or obese and a family history of the illness increase the odds of developing the disease．
68．The first sentence in the passage is used to __________．
A．tell readers what the passage focuses on
B．give a very good guessing

Garland"s research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There"s nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said， adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don"t produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
61. According to the passage, people are advised to take more Vitamin D, because__.
A. it is nutritious B. it can‘t harm people’s health

Here is how your health risks increase at different BMIs(体重指数) if your waist circumference（腰围） is higher than 40 inches（102 cm） in men and 35 inches （88 cm） in women:
·If your BMI is in the 18.5 to 24.9 range, or “Normal”, then a larger waist that is near or greater than 40 inches for men and 35 inches for women can indicate that you are at “increased” risk.
·If your BMI is in the 25 to 29.9 range, or “Overweight”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “increased” risk. Above these sizes,the risk is considered “high”.
·If your BMI is in the 30 to 34.9 range, or “Obese(肥胖症)I”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “high” risk. Above these sizes, the risk is considered “very high.”
·If your BMI is in the 35 to 39.9 range, or “Obese II”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “very high” risk. Above these sizes, the risk is still considered “very high”.
·If your BMI is or in the 40 + range, or “Obese III”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “extremely high” risk. Above these sizes, the risk is still considered “extremely high”.

Although we already know a great deal about flu, and although the World Health Organization is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be. There are three kinds of flu virus, known as A, B and C. Flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies （抗体） which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability（可变性） is less developed in the flu B virus, which affects only human beings. Flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918 and 1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence （病毒性）, the ease with which it can be transmitted and the strength of the opposition it encounters （遇到）. Scientists, however, have a reliable general picture of the world situation. 72. Which of the following is the most appropriate title for the passage? A. Symptoms of Flu B. Man VS Flu Virus C. WHO: The Major Organization against Flu Virus D. Variability of Flu Virus 73. What does the author say about the flu B virus? A. B Virus is relatively stable and causes mild infections that do not spread far through the population. B. B Virus is unstable, and is responsible for the epidemics that cause frequent concern. C. B virus is extremely unstable and is responsible for some of the worst outbreaks of the disease.
D. B virus has a very developed variability, and it affects only human beings. 74. Which of the following is NOT mentioned as a factor contributing to the extent to which a virus spreads?A. The strength of the virus. B.The ease with which the virus can be transmitted. C. The strength of the opposition. D.The immunity the virus can bring about. 75.
