Naturally, parents praise their kids. They want to encourage their children every day. But when it comes to building self-esteem (自尊) in children, praise doesn't always have a positive effect, according to a special edition of the journal Child Development. The issue, edited by Eddie and Thomas, is focused on research into how children develop a sense of self and building your child's confidence takes different skills than you might think.

    Eddie points out that children are born without a sense of self, but it doesn't take long before some kids have a lot of confidence and may feel superior to peers, while others may carry more self-doubt and see themselves as inferior. Yet no one really understands what causes children to view themselves the way they do. Surprisingly little is known about the origins of children's self-concept,” Eddie said.

    Research has found that when kids have a warm, loving relationship with their parents, they develop higher self-esteem. However, when they are given endless praise that is inequal to their achievements, their self-esteem may drop.

    Instead of lavish praise, parents should focus on warmth to build self-esteem, researchers have found—specifically, parents should show interest in their kids' activities and share joy with them. This makes children feel noticed and valued. According to Eddie's own research, children may develop lower self-esteem when their parents give them lots of positive and overstated praises. Too much praise can make children worry about disappointing their parents, and may lead to an unhealthy attitude toward failure. Other studies suggest that parents can teach children that failure is beneficial by encouraging kids to ask themselves: “Why didn't I achieve the result I wanted, and what can I do to change the outcome in the future?”

    Additionally, it's important for parents to encourage the belief that kids can develop basic abilities through devotion and hard work. Kids who are praised for their effort instead of their ability are more likely to develop a growth mindset, which have a positive impact on their confidence.

    Edgar Allan Poe was an American writer who helped shape the course of American literature. His life was full of tragedy and despair, but he managed some of the most influential American literature of the 19th century and continues to influence writers to this day.

    The early life of Edgar Allan Poe was quite miserable.Born in 1809, Poe was not yet three years old when his parents died.Adopted by a wealthy family,he got into trouble at school.He  entered the United States Military Academy at West Point,but he dropped out without graduating. His misery continued to his adult life.Later,because of a failed marriage, he suffered from mental illness. He was so upset about real life that he turned to writing.Expressing himself in an unreal and imaginary world was his only comfort.

    The tragedies in Poe's life influenced the tone,style and contents of his writing.His stories usually include death,which help build his reputation as a master of"dark"literature.In his The

    Tell-Tale Heart, the main character goes crazy and kills his roommate while in The Black Cat, the narrator kills his cat in a fit of madness.

    Poe died at the age of 40 in 1849.His life was tragic and short,but his legacy(遗产) is enormous.Poe is credited with creating crime fiction,and many say he contributed greatly to the appearance of science fiction.Fascinated by the scientific theories and new inventions of his time, he wrote about imaginary societies in the future.Writers such as Arthur Conan Doyle,the author of Sherlock Holmes,regarded Poe as the father of detective fiction. Jules Verne, a French writer who helped popularize science fiction,said Poe's work had a direct influence on the stories he wrote.

    Gregory Talley used to sleep in a park or under a bridge. The 50-year-old has been homeless for more than 10 years.

    “It is hard. It's hard to live homeless. You filled every day trying to find cut where you are going to get something to eat. If I hadn't found wonderful Fairfax County Kennedy Shelter, I wouldn't know where I would be by now. I might be dead,” Talley said.

    The Kennedy Shelter is one of the facilities New Hope Housing provides for homeless people.

    Pam Micheli has devoted her life to making the lives of this vulnerable（易受伤的）population better as executive director of the non-profit organization.

    “I went to Africa in 1985. And I saw a huge amount of poverty, but I saw so much hope. And I decided that I should try to do something that would bring hope to people,” Michell said.

    When Michell began working with New Hope Housing 25 years ago, its three shelters had about 80 beds. Now, it has 350 beds and serves about 1,500 homeless people every year. She has expanded the program beyond just providing beds for the night.

    “We do outreach（拓展）, we do prevention, we do permanent housing. We do transitional housing. We have an education program with all sorts of different things to move people to end their homelessness,” she said, “Our Out of Poverty program is not just about money. It's about you could be spiritually poor, you could be relationship poor ... you could be educationally poor. So it is focusing on how you get out of this poverty that has brought you to being homeless. The program tries to teach the shelter residents self-reliance（自立）and work values, and includes courses on planning and personal responsibility.

    “I learned I still have opportunities to change it and I can change it,” said shelter resident Lewis Webster. “It is just about going forth in doing necessary work to do it. I mean if you really want better, you would do better and that's the frame of mind of me now.”

    China is a country of many resources. Among its resources are many great rivers, which provide useful transport routes. Water transport is an efficient way to carry heavy loads, such as grain. In ancient times, a waterway was needed between China's rich farmlands and the capital city. This need inspired engineers to build a canal. According to writings by the ancient thinker Confucius, work on a canal linking the Yangtze River with the city of Huai-in began about 486 B.C. For many centuries afterward, Chinese emperors worked on extending this ancient canal.

    This canal is now known as China's Grand Canal. One thousand years after the original canal was begun, it was in extreme need of repair. This was in the year 607, during the Sui Dynasty. By 610 the emperor had had the canal extended. The Grand Canal formed a northeast-southwest link between the Yellow River in the north and the Huai River in the south. The canal remained the main waterway in this part of China for the next five hundred years.

    In the thirteenth century, the Mongols had conquered China. The Yuan Dynasty established Beijing as the capital. The city's growing population needed food, so a new canal was built to extend shipping. Building this part of the Grand Canal required enormous effort and cost. Neither the first attempt nor the second one was successful, so the builders chose another route. Finally this link in the Grand Canal was finished.

    By the time of the Ming Dynasty, the Grand Canal had six sections. These were busy with goods until the nineteenth century. Then a series of severe floods struck China. Parts of the Grand Canal were badly damaged. By 1868 it had been largely abandoned as a means of northern route.

    The Grand Canal was mostly restored in the twentieth century. It was widened and deepened, and a new section was constructed. Today the canal, which is about 1,200 miles in length, has new locks(运河的水闸). It is busy with ships and barges(驳船) carrying goods to and from cities along its banks.

    I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St, Lucie just minutes from the ocean, an un-controllable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida's mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.

    I'm like a migratory bird (候鸟) that has lost its sense of timing and direction, my wings flapping against season.

    So what makes me fly against the tide of snowbirds? The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display of colors-first in the fall trees, and then in the lights around homes and at Rockefeller Center. Floridians decorate too, but can't create the special feel of a New England winter.

    I suppose the biggest reason why I return is to celebrate the holidays with people I haven't seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors children excitedly open gifts on Christmas? Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch. (My wife and I spend winters at a retirement community in Ridge, and I'm grateful that I don't have to shovel.)

    While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can't go home?

Tang Dynasty poets sang for about three centuries in different tones. There were many famous poets living in the Tang period, such as Li Bai, Du Fu, Bai Juyi and Li Shangyin. Poems of the Tang Dynasty edited in the Qing Dynasty is a collection of more than 48,900 poems that were written by over 2,200 poets. But it didn't cover all the poems of the Tang Dynasty.

During the Tang Dynasty, poems were recited when lovers walked under the moonlight. Poems were also recited when soldiers fought on the battlefield. People recited them in the open air or at temple fairs.

 Tang Dynasty poets wrote poems to win fame and also to develop their temperament(性情). They poured out deep feelings for their friends and criticised injustice in the society through poems.

 In the Tang Dynasty scholars had to be poets. Their readers were not only people of high social position but also common people. Poets recited poems, women singers sang poems and other ranks of people, including old women and children, read Tang poems. This atmosphere affected foreigners who visited the country at that time. As a result, Tang poetry was introduced to some adjacent countries, like Japan and Vietnam.

 Tang poetry is a most brilliant page in the history of ancient Chinese literature. It's a miracle in the cultural history of mankind. The Tang Dynasty was a powerful empire with a vast territory. It inherited (继承) Chinese civilisation that went back to ancient times, and was combined with the best of other cultures and adopted the benefits of other nations in the world. Tang poetry wasn't the only spiritual wealth created by the Tang Dynasty people. Philosophy and religion, handwriting and painting, and music and dance all gained new peaks of development. Tang poetry, however, was the jewel in the crown and its greatest achievement.
