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 he doesn'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 the 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.

    Being outspoken is a quality that, when used with skill and wisdom, can set you apart from the crowd. {#blank#}1{#/blank#} The quality of being outspoken is a positive and active skill. Here are some tips.

    Gain self-knowledge(自找认识)through journaling. Knowing who you are, what you believe, and how you feel is the beginning of knowing yourself, and journaling is a great way to gain that knowledge. {#blank#}2{#/blank#} Not only can you know yourself better, journaling is an excellent tool to improve self-confidence. Self-confidence is the foundation of being outspoken.

    {#blank#}3{#/blank#} In order to be outspoken, you have to believe that your voice has worth. You have to believe that your input will make any conversation better. And it probably will! It's different opinions that make conversations or debates interesting.

    Overcome shyness. The fact that you're confident doesn't mean you like hearing your own voice. {#blank#}4{#/blank#} Overcoming a natural tendency towards shyness can seem horrible, but doing the opposite of your natural instinct can open up a whole new set of choices: brave choices.

    Back up your opinion with facts. Some people feel uncomfortable having or expressing an opinion because they don't know much about a topic. {#blank#}5{#/blank#} 

A. Be confident

B. Open your mind and speak it out.

C. The next step is overcoming your shyness.

D. Practice journaling for 15 minutes each night before bed.

E. Being outspoken is to speak your mind—to be honest and frank.

F. Allowing the other parties to make their points fully can help you seem more reasonable.

G. You can combat this feeling and have more confidence about your opinion if you learn facts that can support your opinion.

    The old man walked with a cane (拐杖) slowly into the restaurant. His poor jacket, patched (打补丁的) trousers, and worn-out shoes made him stand out from the usual Saturday morning breakfast crowd. Unforgettable were his pale blue eyes that sparkled (闪光) like diamonds, large rosy cheeks, and thin lips that held a steady smile. He walked toward a table by the window. A young waitress watched him and ran over to him, saying, “Here, Sir. Let me give you a hand with that chair.” Without a word, he smiled and nodded a thank you. She pulled the chair away from the table. Supporting him with one arm, she helped him move in front of the chair, and get comfortably seated. Then she pushed the table up close to him, and leaned his cane against the table where he could reach it. In a soft, clear voice he said, “Thank you, Miss.” “You're welcome, Sir.” She replied. “My name is Mary. I'll be back in a moment. If you need anything, just wave at me.”

    After he had finished a hearty meal of pancakes, bacon, and hot lemon tea, Mary brought him the change, helping him up from his chair and out from behind the table. She handed him his cane, and walked with him to the front door. Holding the door open for him, she said, “Come back and see us, Sir!” He nodded a thank you and said softly with a smile, “You are very kind!”

    When Mary went to clean his table, she was shocked. Under his plate she found a business card and a note written on the napkin, under which was a $ 100 bill. The note on the napkin read, “Dear Mary, I respect you very much, and you respect yourself, too. It shows by the way you treat others. You have found the secret of happiness. Your kind gestures will shine through those who meet you.”

    The man she had served was the owner of the restaurant. This was the first time that she, or any of his employees, had seen him in person.

    Every person has their own way of saying things, their own special expressions. Many everyday American expression are based on colors.

    Red is a hot colour. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their colour and their fiery taste. Fast loud music is popular with many people. They may say the music is popular with many people. They may say the music is red hot, especially the kind called Dixicland jazz.

    Pink is a lighter kind of red. People sometimes say they're in the pink when they're in good health. The expression was first used in America at the beginning of the 20th century. It probably came from many babies who were born with a nice pink colour showing good health.

Blue is a cool colour. The traditional blues music in t he United States is the opposite of red hot music. Blues is slow, sad and soulful. Duke Ellington and his orchestra recorded a famous song—Mood Indigo—about the deep blue colour, indigo. In the words of the song: “You aren't blue till you've had that Mood Indigo.” Someone who is blue is very sad.

    The colour green is natural for trees and grass. But it is an unnatural colour for humans. A person who has a sick feeling in his stomach may say he feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.

    Sometimes a person may be upset because he does not have something as nice as his friend's, like a fast new car. That person may say he is green with envy. Some people are green with envy because a friend has more dollars of greenbacks. Dollars are called greenbacks because that is the colour of the back side of the paper money.

    The colour black is often used in expressions. People describe a day in which everything goes wrong as a black day. The date of a major tragedy is remembered as a black day. a blacklist is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.

The surface of Venus has never seemed very hospitable. Temperatures change around 470℃(900°F), the result of a runway greenhouse effect, and the pressure of its atmosphere, thick with carbon dioxide and sulfuric acid(硫酸), is some 90 times that of Earth's. Lead(铅) would flow like water on Venus, and water cannot have existed in liquid form for perhaps a billion years.

    Now NASA'S Magellan spacecraft seems to have found one more horror in the nasty landscape: active volcanoes. Last week the space agency released the first detailed map of Venus and the most dramatic images ever made of its surface. The picture offer the best evidence to date that a planet once assumed dead is actually a lively pot of geological change.

    The most amazing image is of Venus's second tallest mountain, Maat Mons, which rises 8km(5 miles) . Most of the planet's many peaks, including 9.5-km-(6-mile-) high Maxwell Montes, look bright in the radar pictures Magellan takes from its orbit above the permanent could cover. That means they are strong reflectors of radar waves. But Maat Mons is dark; like the Stealth bomber, it absorbs much of the radar falling on it.

    This interesting fact, say project scientists, is a strong hint that the mountains has recently been covered with lava(熔岩). Rock that sits on the surface of mountaintops appears to weather quickly in the hot , chemically reactive atmosphere, creating a soil that is rich in iron sulfide(硫化铁). It is this mineral, the scientists believe, that can easily be seen on radar. If Maat Mons doesn't have any, it has probably been resurfaced, perhaps within the past few years.

    Such resurfacing has undoubtedly taken place in Venus lowlands: earlier images of the planet showed vast areas that are remarkably free of craters(火山坑). That would be easy to explain on a Planet like Earth, where cratering from meteor strikes is erased by steady erosion. But while there is some evidence of wind erosion on Venus, the best explanation for the lack of cratering is periodic lava flow. Magellan has found direct evidence of such flows, including domelike upwellings and hardened streamed of rock trailing down the sides of Venusian peaks. There are also signs of other geologic activities, including dramatic faulting and several distinct incidents of mountain building. But the evidence can't indicate whether they really occurred millions of years ago. The case for active Venusian volcanoes is not yet proved, but Magellan, which is now well into its second complete survey of the planet's surface, may eventually settle the issue.

First published on October 15, 1952, "Charlotte's Web" is a popular children's book written by well-known American author E. B. White and {#blank#}1{#/blank#}（illustrate）by Garth Williams that deals with themes of the nature of friendship, loss, fate, acceptance, and renewal. The story centers on a pig named Wilbur and the unlikely but deep friendship {#blank#}2{#/blank#} shares with an uncommonly talented spider named Charlotte.

While it's normal in the course of events on a farm for pigs {#blank#}3{#/blank#}（kill）when they reach a certain size and age, clever Charlotte works out a scheme to keep Wilbur from his fate by weaving words into her web to create what amounts to a one-pig publicity campaign. By promoting Wilbur to celebrity status, Charlotte ultimately saves him {#blank#}4{#/blank#} his date with the butcher's knife.

The ending of the "Charlotte's Web" is bittersweet, however, {#blank#}5{#/blank#} while Wilbur survives, Charlotte does not. But even Charlotte's passing is a lesson-for Wilbur and those reading his story-about the nature of death and renewal.

Death and destiny are both themes that the book explores. While Charlotte is willing to help Wilbur avoid a destiny that's being imposed on him by outside forces beyond his control, she also understands that some fates are inevitable: All living creatures are born, {#blank#}6{#/blank#}（have）a life cycle, and die. Charlotte accepts her role in this natural circle without regret.

Charlotte helps Wilbur realize that immortality is not about living forever, but rather, {#blank#}7{#/blank#}（ensure）that new generations will follow. She also helps him understand that love and friendship are not fixed in quantity. While we may lose a friend, new friendships can come along, not as replacements for {#blank#}8{#/blank#} we've lost, but as blessings to build on what we've learned.

"Charlotte's Web" got its inspiration from true experiences that author E. B. White had on his farm in Maine, {#blank#}9{#/blank#} he penned the book and lived until his death in 1985．While the author claims that the book {#blank#}10{#/blank#} never be considered a moral tale, certain messages related to moral principles, or rights and wrongs, are obviously established in "Charlotte's Web".
