There is a joke among flu researchers: “If you've seen one flu season, you've seen one flu season.” The joke is about the unpredictable nature of the flu virus.Every year it looks different, and every strain (类型) follows its own pattern — it's the reason why new strains like H1N1 are extremely difficult to predict.
Dr.Michael Osterholm is a former adviser to the U.S.Department of Health and Human Services.“I know less about influenza today than I did 10 years ago,” he says in a joking way.“Every stone we've turned over, we get more questions.”
The flu rectums every season and the world experiences terrible pandemics (全国或全世界范围流行的疾病), but researchers still do not understand why some strains infect people and others do not; they are not entirely sure about how the flu is transmitted; nor do they understand why some patients become seriously ill while others develop mild symptoms (症状).As a result, when a new strain shows up — like H1N1 — they often have little information to fall back on, and the lessons of previous pandemics are only somewhat helpful.While researchers are still putting together a complete picture of H1N1, for example, its most striking difference with the seasonal flu is that the elder1y are not the most vulnerable (易受攻击的) population.
Influenza's unpredictable nature makes it a moving target for researchers, says researcher Allison Aiello at the University of Michigan.“Even if we had complete seasonal flu data from the past, it wouldn't be much helpful for a new strain of influenza,” she explains.
Whi1e researchers are frustrated by the holes in their knowledge, they say, however, that the pub1ic--health community is generally doing a very good job responding to H1N1 with seasonal flu data that do exist.Studying influenza, says Osterholm, is “like looking through the windows of a house you can't get into because the door is locked.” Gathering the data researchers do have is like “looking through the windows to get a pretty good picture of what the inside looks like.”
One thing researchers do know for sure: the best way for people to protect against H1N1 is to get the vaccine once it becomes available to them.
What do we learn about H1N1 from the passage?
A.In fact it is not a kind of influenza virus.
B.It is quite possible to predict it in theory.
C.Old people are more likely to contract it than kids.
D.Receiving vaccines will be effective to protect against it.
The underlined phrase “fall back on” in Para.3 probably means .
A.rely on B.pass on C.col1ect D.exchange
What do we know about previous seasonal flu data?
A.It is useless to study them.
B.It is still necessary to study them.
C.They are misleading most of the time.
D.They are much more helpful than expected.
Which of the following could be the best title for the passage?
A.Outbreaks of the flu B.Symptoms of the flu
C.Mysteries of the flu D.Risks of the flu

A. How much sleep you need
Sleep cycles & stages, lack of sleep.
Getting the hours you need to sleep consist of a series of distinct cycles and stages that restore and refresh your body and mind.
Even minimal sleep loss takes a toll on your mood, energy, efficiency and ability to handle stress.
B. Panic attacks and panic disorder

E. What you need to know about anti-anxiety drugs

Medication doesn’t cure the underlying problem and is usually not a long-term solution. Anxiety medications also come with side effects and safety concerns, including the risk of addiction..
F. Understanding stress
Modern life is full of hassles, deadlines, frustrations, and demands. For many people, stress is so commonplace that it has become a way of life. Stress isn’t always bad. In small doses, it can help you perform under pressure and motivate you to do your best. But when you’re constantly running in emergency mode, your mind and body pay the price.

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body's special needs. Both types have simply been called “well.” In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body's condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap may be “well,” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.

A. good health is more than not being ill

4.According to what the author, which of the following groups of people would be inferred healthy?
A. People who have strong muscles as well as slim figures.
B. People who are not presently experiencing any symptoms of disease.
