We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    March 8 marks the annual International Women's Day. Around the world, women usually played a not well-known role in history. They were often buried with their unknown talents and amazing tales. Yet there are still some lucky ones whose stories have been recorded. Here are six talented ancient Chinese women who once impressed in their time, and still affect us in our time.

    Praised as the “No.1 talented woman”, Li Qingzhao, a poet from the Song Dynasty, was born in Shandong province. She excelled at poetry and in ink painting and calligraphy (书法). Li was most well-known for her poems, which were divided into two contrasting styles reflecting her life as a married woman and a widow. Before her husband's death, her poems were mainly about a carefree and happy life. The keynote turned into a sad tune after her husband passed away. However, Li was not a narrow-minded woman. Apart from expressing feminine (女性的) feelings and experiences, she also wrote poems praising war heroes and criticizing the corrupted emperor. As an example of female patriot, Li has a great effect on modern women's literature.

    Cai Wenji was good not only at poetry and calligraphy, but also mathematics, astronomy, debate and music. Her masterpieces were Hu Jia Shi Ba Pai. As the daughter of literatus Cai Yi of the Eastern Han Dynasty, Cai had a very unusual life. After her first husband died, she was forced to marry Xiongnu tribe's king. Living in a totally different environment, Cai was very homesick. Twelve years later, Cao Cao, a student of Cai Yi, rescued Cai from the Xiongnu tribe. At the age of 35, Cai got married for a third time in a union arranged by Cao to a man named Dong Si.

    Ban Zhao was the first female historian in China. She was also good at writing poems, yet only seven of her works have survived. Ban was often invited by the emperor to teach the queen mathematics, astronomy and poetry. She was honored as Da Gu, a title for knowledgeable and noble women. At the age of 40, Ban finished Han Shu, based on her brother's writings. A total of four people wrote the book, and Ban, as the last writer, faithfully kept the style of the first three. Ban Zhao also wrote Nv Jie, a book to teach women how to deal with relationships with their husbands and husbands' relatives and how to properly behave.

    Shangguan Wan'er was famous for being given an important position by the only female emperor, Wu Zetian of the Tang Dynasty. Despite Shangguan's grandfather being killed for offending Wu, she was highly praised by the female emperor for her literary talent. She served as a key secretary to Wu and was called “a female prime minister” at the time. Shangguan changed court poetry so that it used more meaningful expressions than empty praise, and further developed her style based on her grandfather's poems.

    Su Hui was known for a handkerchief she made. It was embroidered (刺绣) with 841 characters that could form 7,958 poems. Named Xuan Ji Tu, the handkerchief was originally made by Su to send to her husband, Dou Tao. Su waited for her husband to come back after Dou's exile (流放), yet Dou had an affair with another woman. Sad and angry, Su created the poems on a handkerchief in red, yellow, blue, white, black and purple silk thread and sent it to her husband. Dou was deeply moved by the poems, felt guilty for his behavior and reunited with Su.

    When Xue Tao's name was mentioned, people would think of the famous Xue Tao Jian, a sort of small-size colorful writing paper. It is recorded that Xue Tao created this colored paper to write poems. During her time, writing paper was yellow, yet Xue changed the simple color into different shades of red or green. Later, people made similar colorful paper and named them “Xue Tao Jian”. Xue had talent for poetry and music. Her poems were not limited to those private feminine feelings and emotions; she also expressed her empathy (共鸣) to soldiers on the frontier.

    Don't waste your money on this magazine. 60-70 percent of it are advertisements, and the articles offer little useful information. It might be suitable for children, but not adults who are serious about educating themselves about dogs.

    Dog World has many very interesting and thought-provoking (令人思考的) articles for people involved in dog showing, breeding(饲养), performance events, etc. However，over half of the magazine is devoted to breeder ads, which is boring. Still, as a whole, I recommend(推荐) it for the articles. Good articles, but tons of ads.

    My new favorite magazine! Beautiful photos, smart and amusing articles, fashion, art, interviews with famous people… all with a dog focus！Cover models range from Paris Hilton and Tinkerbell to Virginia Madsen and her dogs. Thanks to Modern Dog I now know how to give a dog-friendly cocktail party and how to actually get my dog to come when she's called. Surely worth checking out.

    In many countries, authority is seldom questioned, either because it is highly respected, or because it is feared. Because rank has been important in certain societies for a long time, people have been trained never to question those in authority. For example, children are not expected to question their teachers in school. It may be considered improper for young businessmen to suggest ideas that differ from those of older, more experienced members of the business.

    In other countries, including America, children are trained to question and search for answers. When a child asks a question, he will often be told to go to the library and find the answer for himself. By the time students reach the age of 14 or 15, they may be developing exciting new ideas in all fields of science and arts. To encourage such creativity, there are many national prizes offered to students every year for their scientific discoveries and artistic accomplishments.

    This interest in questioning and searching may be considered by some people as bad for young people's manners, that young people lack respect for authority. This impression may be created when visitors notice young Americans asking questions and arguing with older people. However, this is because many Americans have a different attitude toward authority than may exist in other areas of the world. In a work or business situation, ideas are freely and openly discussed and argued. It is important to remember that it is the person's ideas that are being questioned, not the individual himself. The two are quite separate. The purpose of the searching, questioning, and arguing is to find the facts in a particular situation, and therefore a solution, so that the work of the business can progress in the most effective manner possible.

    As was mentioned earlier, you may notice the same questioning in social conversations. Although some individual may think that Americans are rude because of the direct manner with people, they are merely trying to learn more about your ideas.

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

    Despite the celebrations, though, in the U. S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

    It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    "Jazz seems like it's not really a part of the American appetite, "Moran tells National Public Radio's reporter Neal Conan. "What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's actually color, and it's actually digital. "

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. "The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same, "says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, "just to kind of put it back in the mind that Waller is dance music as much as it is concert music," says Moran. "For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context," says Moran, "so I want to continue those dialogues. Those are the things I want to foster. "
