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.

Most people don't know the true story of the little boy who came to be known as Douglas Craig. He was found wandering around the streets of Washington, D.C. He could not hear or speak. At night, he drew the knees up to his body in doorways and slept. Sometimes people pitied him and gave him food and clothing. If not, he ate what he could find in garbage cans.
Dr. E. M. Gallaudet at Gallaudet College let him stay in the Kendall School until he was old enough to work. He became the best "handy man" that Gallaudet had ever had. He had many duties, such as picking up mail at the post office, mowing grass, tending the flower beds, and carrying notes from the boys to the girls. Clearly, he was a familiar sight on campus.
It is said that Douglas courted(求爱) a black woman from Baltimore. Since his courtship required letter-writing, and he was illiterate, he had a student in the college act as his "private secretary." Though that relationship did not work out, he did marry a black deaf woman. The wedding took place in a church, and most of the college faculty and teachers were present. Douglas was dressed in a full-dress suit with a white tie and white gloves. The happy couple went to Baltimore for a honeymoon, but the honeymoon only lasted for one day. Their plans were cut short when his pocketbook containing about $300 was either lost or stolen.
He once went to Norfolk, Virginia on a vacation, but he did not know what a vacation was. He spent the entire time working around the docks of Norfolk. He came home with a pocketful of money, and told everyone that he had a fine vacation.
Douglas' last public duty was to raise the flag to the top of the new flagpole. He was very weak and sat in an armchair during the ceremonies. He died in 1936, but left a legend at Gallaudet that would live forever.
1. The main idea of the story is that_____:
A. Craig liked no women except those from universities.
B. Gallaudet is the best place for an orphan to grow up.
C. No one ever found out exactly what happened to Craig’s family.

2. It is most likely that Douglas Craig enjoyed working at Gallaudet because_____:
A. Gallaudet was a good place to collect junk. B. he found it easy to communicate with people.
C. people felt sorry for him so he didn't have to work hard. D. he didn't have a home.
3. Craig and his new wife's honeymoon did not last long because_______:
A. their money was lost or stolen. B. Craig missed Gallaudet and wanted to come back early.
C. they spent all their money. D. their baggage and clothing was lost or stolen.

From hitting the mall with your girl fiends on a Saturday afternoon, to holiday spending on gifts that go under the tree, shopping could be called one of America’s favorite pastimes. For most people, it means some new clothes for work or a small trinket for a friend. For others, however, shopping is much more than an enjoyable pastime, and in some cases, it is a real and destructive addiction that can turn into a financial disaster. Compulsive shopping and spending are defined as inappropriate, excessive过度的, and out of control. Like other addictions, it basically has something to do with impulsiveness and lack of control over one’s impulses冲动. In America, shopping is embedded in our culture; so often, the impulsiveness comes out as excessive shopping. Sometimes this is referred to as “shopholism”. Shopping addiction can damage a person’s life, family, and finances. “No one knows what causes addictive behaviors, like shopping, alcoholism, drug abuse, and gambling”, says a professor of applied health science. Some of the new evidence suggests that some people, maybe 10%-15%, may have a genetic predisposition to an addictive behavior, coupled with an environment in which the particular behavior is triggered引发, but no one really knows why.” Individuals will get some kind of high from an addictive behavior like shopping.
What are the telltale signs that shopping has crossed the line and become and addiction? What should a concerned family member or friend look out for when they think shopping has become a problem? The behaviors can signal a serious problem:
·Shopping or spending money as a result of feeling angry, depressed, anxious, or lonely
·Having arguments with others about one’s shopping habits
·Feeling lost without credit cards — actually going into withdrawal without them
·Buying items on credit, rather than with cash
·Describing a rush or a feeling of euphoria with spending
·Feeling guilty, ashamed, or embarrassed after a spending spree(大买特买)
·Thinking obsessively about money
·Spending a lot time juggling accounts or bills to accommodate spending
“If someone identifies four or more of any of these behaviors, there may be a problem”, experts say. Treating a shopping addiction requires a multifaceted approach. There are no standard treatments for shopping addiction. Medications have been used, but with mixed results. Therapists also focus on cognitive-behavioral treatment programs. There is no quick and easy answer that will immediately cure a shopping addiction, and while treatment is a necessary part of solving the problem, so is behavior change on the part of the addict.
Some basic changes in behavior that will have a big impact on breaking a shopping addiction are recommended:
·Admit that you are a compulsive spender, which is half the battle.
·Get rid of checkbooks and credit cards, which fuel the problem.
·Don’t shop by yourself because most compulsive shoppers shop alone and if you are with someone you are much less likely to append more.
·Find other meaningful ways to spend time.
And keep in mind that while behavior change is clearly important to recovery, so is reaching out for professional help.(509)

China supports international efforts to secure cyberspace but believes each nation’s “Internet sovereignty（主权）” must be respected, a top Chinese official said at a cyber security conference on Tuesday.
“China, like many other countries, is very concerned about cyber security,” said Liu Zhengrong, deputy director general of the Internet Affairs Bureau of the State Council Information Office.
“China faces severe cyber security threats,” Liu told participants here at the Worldwide Cyber Security Summit, a gathering of government and business leaders from 40 countries hosted by the EastWest Institute think tank.
“International cooperation is much needed to safeguard international cyberspace,” Liu said.
But “Internet sovereignty of each country needs to be respected,” the Chinese official added. “Different national and cultural conditions” should be taken into account.
Liu declined to answer repeated questions about cyber attacks last year on Google which the Internet giant said originated in China and led to the California company’s decision to reroute its searches through Hong Kong.
“The Chinese government firmly opposes cyber attacks in any form and Chinese law clearly states that any hackers will be held responsible for their actions,” he said.
Liu said China itself is a “a major victim of cyber attacks and network viruses” and has laws in place to deal with hackers.
“Internet-related crimes (in China) are showing a steady upward trend,” Liu said. “We suffer big economic losses from hacking networks and viruses - around $1 billion dollars (6.8 billion yuan) a year.”
In 2009, Chinese law enforcement authorities investigated about 48,000 cases, a 37 percent increase over 2008, he said.
While China has a dynamic Internet population of more than 400 million users and millions of bloggers, there is no “absolute freedom” on the Web, Liu said.
“I don’t think there is absolute freedom in this world,” he said. “When you are speaking via the Internet you must obey laws and respect others’ lawful rights.”
Last Thursday, Wang Chen, minister of the State Council Information Office, said China has been actively promoting a real-name registration system for Internet and cell phone users to better manage Internet information and services.
China needs laws that will step up monitoring for “harmful information” and block “overseas hostile forces from infiltrating（渗透）through the Internet,” Wang said.
Last week, China tightened its State Secrets law, holding Internet and mobile phone operators responsible for customers who try to leak State secrets.
Some 400 government officials, business leaders and cyber security experts are attending the summit, which features three days of discussions on ways to protect the world’s digital infrastructure from electronic threats.(427)
