If you see a person carelessly throw a cigarette to the ground, what are you likely to think?
If you hate people throwing things on the ground, you might think, “That person shouldn’t litter.” If you are a smoker, you might think, “I would sure like a cigarette right now.”
Most likely, though, you are not thinking, “That unused cigarette butt could be used to make something amazing!”
That is, unless you are a creative scientist. If you are, you may see potential—a possibility—where others simply see trash（垃圾）. That is just what has happened in South Korea.
The spirit of invention can hit at the strangest times and in the most unusual places. In South Korea, it happened near a trash can.
Kin Gil-Pyo is with the Seoul National University. He says he saw people throwing away cigarette butts, which got him thinking. He began wondering if something useful could be made from them.
He and other researchers found a way to convert cigarette butts into materials required for high-performance batteries.
Kim Gil-Pyo says they looked closely at used cigarette filters（滤嘴）, the parts of cigarettes smokers put into their mouths. Filters are made of a material called “cellulose acetate（醋酸纤维素）.”
Mr. Kim explains that cellulose acetate can be made into another material: carbon. The pieces of cellulose acetate, known as fibers, are changed through a one-step burning process. After this, they are turned into an energy storage material.
But why use carbon? Carbon has many qualities that seem to make it the perfect material. Carbon has a high surface area. It conducts electricity well. It also stays stable, unlikely to change, for a long time. And carbon does not cost a lot. All these qualities make it the most popular material for making super-capacitors（超级电容器）.
Super-capacitors are good at storing energy. They have high-power mass, or density(密度). They require only a short time for recharging. And they have a long lifecycle. Super-capacitors are used in products such as laptop computers and cell phones. They are also used in industrial energy converters, like wind turbine machines.
Combining carbon and super-capacitors seems like a perfect marriage.
Kim Gil-Pyo tells the Reuters News Agency that cigarette butts could affect the economy is a huge way. They could prove to be a low-cost source of carbon material. They are so cheap that smokers throw them to the ground. And you don’t get much cheaper than that.
1.What may people think seeing a person throw a cigarette to the ground?
A.That all depends. B.He should be blamed.
C.It causes them to smoke. D.The butts can be reused.
2.Filters can be made into a material that .
A.is used as the battery surface
B.can be turned into electricity
C.is very easy and costs nothing
D.can hold electricity energy well
3.Super-capacitors made from carbon .
A.need quite a long time to recharge
B.are comparatively very expensive
C.can easily carry an electrical current
D.can save a large quantity of electricity
4.The story tells the readers the truth that .
A.where there is a will, there is a way
B.the most useless is usually the most useful
C.ideas usually hit at the most unusual places
D.one person’s trash is another person’s treasure

A newly-published study has shown that loneliness can spread from one person to another, like a disease.
Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.
Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.
University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.
Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.
The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.
The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.
Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.
The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.
1.From the passage, we can learn that ________________.
A. the habit of littering doesn’t spread
B. a lonely person won’t have friends
C. everyone may be affected by others’ loneliness
D. lonely people don’t know the cause of their loneliness
2.Which statement about the spread of loneliness is true?
A. The spreading effect was the second strongest among friends.
B. No spreading effect was found on husbands and wives.
C. Women are more likely to be affected than men.
D. Brothers are more easily affected than neighbors.
3. If you make 10 more friends in a year, the days of your feeling loneliness will be reduced by .
A. 48 days B. 25 days C. 20 days D. 15 days
4.What is the main idea of the passage?
A. Actions should be taken to help lonely people. B. People feel lonely for many reasons.
C. Ways to fight against loneliness. D. Lonely people can affect others.

Loneliness is like a disease, and what’s worse, it’s contagious. It can spread from one person to another, according to the recent research that stresses the power of one person’s emotions to affect even people they don’t know.
The new analysis, involving 4,793 people who were interviewed every two years between 2005 and 2015, showed that a friend of a lonely person was 52% more likely to develop feelings of loneliness by the time of the next interview. A friend of that person was 25% more likely, and a friend of a friend of a friend was 15% more likely.
''Loneliness is not just the property of an individual. It can be transmitted across people—even people you don’t have direct contact with,” said John T. Cacioppo, a psychologist of University of Chicago who led the study published in the December issue of the Journal of Personality and Social Psychology.
Loneliness has been linked to medical problems, including depression, sleep problems and generally poorer physical health. Identifying some of the causes could help reduce the emotion and improve health, experts said.
Although the study did not examine how loneliness spreads, Cacioppo said another research has provided clues. “Let’s say for whatever reason you get lonely. You then interact with other people in a more negative fashion. That puts them in a negative mood and makes them more likely to interact with other people in a negative fashion and they minimize their social ties and become lonely,” Cacioppo said.
According to Cacioppo, loneliness spread more easily among women than men, perhaps because women were more likely to express emotions.
Lonely people become less and less trusting others. This makes it more and more difficult for them to make friends—and more likely that society will reject them. Therefore, it is important to recognize and deal with loneliness. Cacioppo emphasizes people who have been pushed to the edges of society should receive help to repair their social networks.
