It is a mystery that has puzzled doctors for decades. But experts believe they have now finally solved the tricky question of why winter is notoriously known as the flu season.
According to a new research, the influenza virus coats itself in a protective fatty shield that is tough enough to resist cold temperatures. The butter-like material only melts when it hits the respiratory tract（呼吸道）, leaving the virus free to infect cells-- a process scientists say is like an M&M melting in the mouth.
However, in warmer outdoor temperatures, the protective coating melts before it reaches a person or an animal, killing the bacteria before they can infect someone. Joshua Zimmerberg, from the National Institute of Child Health and Human Development (NICHD), in the US, which led the study, said: “Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid period that the virus is able to enter a cell to infect it.”
In the past, scientists worked on theories that flu is more common in winter because people spend more time inside or the radiation from the sun in summer kills off germs. But no research successfully explained the spread of the disease.
Researchers have already claimed that the report, which is published in the journal Nature Chemical Biology, could lead to new ways to prevent and treat flu. “Now that we understand how the flu virus protects itself so that it can spread from person to person, we can work on ways to prevent it.”
Influenza and other respiratory viruses are spread in small drops broadcast by coughing, sneezing and talking and which can also settle onto surfaces, to be picked up on fingertips.

The term "quiet stress” is gathering pace among experts, who say it's an often overlooked form of the more widely known version, which is characterised by visible outbursts: losing tempers, swearing, shouting, and anger.
"We quietly hold our stress within: we don't speak up about how we feel. And very importantly, we become inactive. We stay in unhappy relationships and unfulfilling jobs. We feel overwhelmed（被压倒的）, yet ignore important administration tasks. Quiet stress creates a form of emotional paralysis （麻痹）that keeps us ' stuck' in unhappy situations, says Jillian Lavender, who runs the London Meditation Centre.
Cary Cooper, a professor of psychology and health at the University of Manchester, likens the effects of quiet stress to shrapnel（榴弹）:“You can learn to quieten your stress responses, but eventually the stress will emerge: as well as a suppressed immune system, you may withdraw socially, isolate yourself and begin to engage in unhealthy habits like comfort eating or drinking too much. Despite getting a bad rap over the years, expressing anger or frustration is far healthier than smiling sweetly while feeling quietly stressed."
A recent study from Stanford University in the US backs this theory up. The researchers found that seeing stress as a helpful part of dealing with life's challenges, rather than as something to be avoided, was associated with better health, emotional well being and productivity at work.
“Stress isn't always harmful,” said Kelly McGonigal, a business school lecturer at Stanford who worked on the study. "Once you appreciate that going through stress makes you better at it, it can be easier to face each new challenge.”
1.Which behavior belongs to “quiet stress” ？
A.Reacting slowly. B.Speaking up.
C.Smiling sweetly. D.Scolding others.
2.What is the best way to relieve from quiet stress according to Cary Cooper?
A.Developing a good habit. B.Eating much junk food.
C.Finishing tasks on time. D.Making your feelings known.
3.According to Paragraph 4 stress is.
A.something beneficial sometimes B.something harmful to health
C.something to be kept D.something affecting work
4.Which of the following statements can describe stress according to the text?
A.Silence is gold. B.Life is not easy.
C.One coin has two sides. D.Stress is everywhere.
