A new study suggests that sad music might actually arouse positive emotions. The finding helps to explain why people enjoy listening to sad music, say Ai Kawakami and her colleagues from Tokyo University of the Arts and the RIKEN Brain Science Institute, Japan. Ai Kawakami and her colleagues asked 44 volunteers, including both musicians and nonspecialists, to listen to two pieces of sad music and one piece of happy music. Each participant was required to use a set of keywords to rate both their perception(观念) of the music and their own emotional state.
The sad pieces of music included Glinka’s La Separation in F minor and Blumenfeld’s Etude Sur Mer in G minor. The happy music piece was Granados’s Allegro de Concierto in G major. To control the “happy” effect of major key, they also played the minor key(小调) pieces in major key, and vise versa.
The researchers explained that sad music aroused contradictory emotions because the participants of the study tended to feel sad to be more tragic and less romantic than they felt themselves while listening to it.
“ In general, sad music causes sadness in listeners, and sadness is regarded as an unpleasant emotion. If sad music actually arouses only unpleasant emotion, we would not listen to it,” the researchers wrote in the study.
“Music that is believed as sad actually causes romantic emotion as well as sad emotion.And people, regardless of their musical training, experience this ambivalent(矛盾的) emotion to listen to the sad music,” added the researchers.
Also, unlike sadness in daily life, sadness experienced through art actually feels pleasant, possibly because the latter does not cause an actual threat to our safety. This could help people to deal with their negative emotions in daily life, concluded the authors.
“Emotion experienced by music has no direct danger or harm unlike the emotion experienced in everyday life. Therefore, we can even enjoy unpleasant emotion such as sadness. If we suffer from unpleasant emotion aroused through daily life, sad music might be helpful to alleviate negative emotion,” they added.

My husband and I had just opened up a pet sitting business earlier that year. Our customers had slowly risen from three to thirty a month. We were busy through those hot summer months, driving between visits. Our services were strictly held at the pet owner’s home. It was almost too busy for the two of us, but we were making good money!
We asked pet owners new to our services to phone two weeks ahead so we had enough time to meet the owners and pets at their homes and make any following meetings before the owner leaves.
One day, we decided to take on a new customer just two days before they would leave. We met the family, filled in a form, and spent some time with their dog, Hercules. He playfully jumped on us and touched our hands and arms using his tongue. The family laughed as he did this, showing us that he was very loving.
Two days later I appeared at the house, alone. I came up to Hercules and said hello happily. I filled up his water bowl and cleaned any messes he made. Meanwhile, he was so lovely sitting beside. I thought this would be the good picture to send to the owners, a usual service. After the light and “click” sound went off, Hercules rushed at me. I didn’t know what had just happened until I noticed the drops of blood. I ran out and did the only thing — calling my husband.
Then I went to neighbors for help. My husband arrived after ten minutes. The helpful neighbor and my husband led Hercules back into his pen (圈). Then my husband and I took off to the hospital.
I must have looked like I was shot when I walked into the hospital. The nurses quickly moved me to a room. I asked the doctor in a weak but playful manner, “ Am I going to die？” He replied, “Finally.”

Snow falls in the Earth’s extreme North and South throughout the year. However， the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道)，but only on the highest mountains.
Snow contains much less water than rain, but much of the water the world uses comes from snow. Melting snow provides water for rivers, electric power stations and agricultural crops. In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.
Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. Snow also influences the movement of sound waves. The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow’s surface will help to send back sound waves.
Snow may be beautiful, but it can be deadly. It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. Others die from heart attacks caused by too much physical activity out in the cold.
People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. These include food，emergency medical supplies，and extra clothing to stay warm and dry.

A．provides up to seventy—five percent of water supplies worldwide

April 11, 2003 12:44 a. m. PST, Associated Press The respiratory(呼吸系统) virus known as SARS has appeared to spread in the United States only to family members of health workers with close contact to a sick person.
On Thursday, the head of the Centers for Disease Control and Prevention said there might be a case of severe acute respiratory syndrome（综合症） spreading through the workplace.
Dr. Julie Gerberding said a suspected SARS virus patient who became ill after traveling to Asia might have infected a co-worker in Florida, which made her “very worried”.
So far, a dozen people—nine family members and three health workers—were infected after coming into close contact with the person with SARS. The rest of the 166 suspected American cases have something to do with people who were infected while traveling in Asia.
In the Gainesville, Fla. area, a 47-year-old woman was believed to have been infected at work by a 60-year-old woman who was the nation’s first suspected SARS case, said Tom Belcuore, director of the Alachua County health department.
Since the World Health Organization announced a worldwide warning last month about SARS, the United States has started infection control in hospitals and among families of suspected cases.
Florida officials said a school in Okaloosa County went through a cleaning after a 6-year-old boy suspected of having SARS appeared at school with slight symptoms. “Health officials are watching the boys’ contacts at school to make sure no one else is infected,” said Rob Hayes, health department spokesman, “The boy may have been infected from a family member,” Hayes said, “We immediately became aware of it and had the child sent home. He’s staying at home with his family until 10 days after symptoms disappear.”
The researchers guessed that the virus might have come from animals. However, the scientists have not ruled out the possibility that some other microbe might also help make SARS more serious or easier to catch.
