The most exciting storms are the ones with flashes of lightning.Unfortunately,those are scarce,unless you are near the Catatumbo River in Northwestern Venezuela.Here,nature's grandest sound and light show is often seen, because it happens about 160 nights a year.And it lasts for as long as 10 hours at a time.And unlike other lightning storms that cause just one or two flashes,this one is with as many as 280 per hour.It is the highest in the world. Besides,each one of them is so powerful that each can power every light bulb in South America.Not surprisingly,they can be seen for almost 250 miles.Fishermen and sailors often use them to guide them across the waters during dark nights.

    What's even more surprising is that the lightning has been happening above the same spot where the Catatumbo River meets Lake Maracaibo for thousands of years.The best part is that the show is different every night.That's because the color of the lightning changes,depending on the amount of water in the atmosphere.On dry nights,the lightning appears white.When the air is not dry,it helps split up the bright light into red,orange and even purple.

    Strangely enough,though this has been going on for centuries,scientists have still not been able to figure out the cause of this phenomenon.Some say that the storms are the result of the interaction of the area's unusual topography（地貌）,wind and heat.Others,however,believe that the storms are caused by a kind of gas in the area.The locals simply think that it is the "spirit of Catatumbo" that lights up the night sky.

    After spending three months in and out of the hospital with numerous health issues, Donald Austin had his leg partially cut off. He was relieved to finally be able to go home after just four days recovering from the operation. When he reached his porch, though, the joy drained away.

    Donald thought he'd be able to make it up the steps to the front door on crutches, but his strength and balance weren't as strong as he'd hoped. The wheelchair was too heavy for his wife, Jennifer Austin, to lift up the steps, even when his mom offered a hand to help. Donald ended up on the concrete, the family feeling totally at a loss. They were out of strength and out of options. Just then, a car caught the family's eyes. It had driven past once but was slowly circling back. The stranger, Steven Smith, pulled up and asked if he could help. Relieved, the family watched Smith lift Donald inside and lay him safely on a couch.

    But the Good Samaritan knew there was more to do. Smith figured this wasn't the only time Donald would need to climb those steps. So the next day, Smith, who's an ordinary worker, came back and asked if he could build a ramp(斜坡) in front of the house. With his dad and a couple more helping hands, Smith set up a ramp over the steps to make the home wheelchair accessible. The act of kindness brought the family to tears.

    “This stranger has saved the day for us twice within 24 hours. He also brightened our spirits that had become increasingly dimmed over the difficult months,” Jennifer wrote on Facebook. “There is a sense of optimism back in our home because of his kindness.”

    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.

    As more and more schools rush to put digital devices（数码设备）in the hands of every student, many parents are becoming increasingly concerned about the quality of their children's education. The promise of increased student academic（学业上的）achievement through the use of technology hasn't produced any significant results in the past 20 years.

    Researchers at the University of California Los Angeles conducted a study in 2014 to determine if the social skills of elementary students were blocked by screen time. Two groups of sixth grade students were compared. One group was sent to an outdoor camp for one week with no screen time, while the control group live life as normal. After one week, the students at camp had made significant improvements over their peers（同龄人）. The good news is that when we limit access to screen time and give children the opportunity to interact face to face, they quickly become better at reading the emotional state of others. The bad news is that we have a generation of children that struggle with this basic emotional intelligence skill.

    Too much screen time has been linked to childhood obesity, sleep disorders, behavior problems, and academic challenges. But is there a difference between schoolwork and entertainment media?

    When students are using technology for academic work they are more likely to be communicating with peers, working cooperatively, and developing other important skills. However, all these are impossible when students watch entertainment media. They just sit and watch!

    Parents have right to be concerned about their children's screen time at school, but they should begin by discussing the use of digital media at home. Some parents are continuously engaged in their own devices, responding to every ring of their phones, receiving and sending messages. How can they expect their children to do better?

The Climb to the Top

    My life as a kid was a sweet life. I lived in a beautiful house with the beautiful surroundings in Puerto Rico. There was one particular thing I loved and it was a huge tree that was in my backyard. As a child, I used to climb the tree every day. Every time I went, I climbed higher and higher, reaching new branches, obstacles, and pathways on my way up. One day, I reached the top and I could see my island. I felt I was on top of the world, and nothing could stop me. Then, there was the day that seemed like the end of my life. This specific day changed my life forever.

It was a nice summer day. After breakfast, my family headed to the park to see my baseball game. In the evening we went to a carnival (嘉年华) in my town. My grandma was selling blankets under a tent. Suddenly, the mood of the day changed when my parents took me to my grandma's tent. Still to this day, I remember the exact words my dad said to me, "Son, how would you like to move to the United States?" I couldn't believe what he said. I then ran away from him as the tears rolled down my cheeks. My perfect life was being taken away from me.

    Two weeks later, we arrived at New York in late July, and my aunt and uncle drove us to Springfield，Massachusetts where we lived for seven years. Once we got there, I met my mom's family for the first time. September came and school started. I was afraid to go to a new school and make new friends. Most kids ignored me and some tried to talk to me, but I couldn't understand them or say anything. My first year in the United States was not fun or easy but I worked hard and got through it.

    Now that I'm grown, I look back on the journey that I've been through: living in a new place with no friends, new language, and new schools. Despite all those problems, I still remembered that special tree. That tree taught me to never give up and reach higher. I have beaten every difficulty that I have met in life and I just kept moving forward. My perfect life was never taken away from me; it has just started.

    America's businesses are getting older and fatter, while many new businesses are dying in infancy.

    A study last month by the Brookings Institution found that the proportion of older firms has grown steadily over several decades, while the survival rate of new companies has fallen. In addition, young people are starting companies at a sharply lower rate than in the past.

    A new report from the National Association of Manufacturers shows a major cause: The cost of obeying government regulations has risen to more than $2 trillion (12.26 trillion yuan) annually, or 12 percent of the GDP, and this cost falls disproportionately on smaller, newer businesses.

    It's risky, difficult and expensive to start a business, and getting more so. Governments are imposing various new rules on a seemingly daily basis: health insurance, minimum wage increases and, most recently in California, compulsory paid sick days for even hourly employees. These regulations shift huge social welfare costs directly onto often-struggling small businesses, while being proportionally much less costly for larger companies.

This is partly an unintended issue of resources—established companies can cope with new costs more easily—but it's also deliberate. For instance, big insurance companies got a seat at the table to help write Obama care, but less politically powerful firms—like medical device manufacturers—got squeezed.

    Mature, successful corporations can employ ex-lawmakers with connections, distribute campaign contributions and even write regulations for themselves. They are also more likely to want to protect steady revenue streams than revolutionize their industry.

Major companies that have been so ill-managed they would otherwise collapse—airlines, car companies and banks—stagger(蹒跚)on because politicians ride to the rescue with bags of taxpayer money.

    The genius of our unique system of government is the determination to protect and defend the rights of the individual over the rights of the nation. As such, the rise of a well-connected oligarchy(寡头政治)that protects big business at the expense of small business, and the established over the new, is opposite to American ideals.

Income inequalitywhich is directly caused by faulty government policy—is being promoted as the reason to impose more of that bad policy. But let's be perfectly clear, we do not have a free market but one where government picks winners and losers through regulations and financial aids.

    Politics is, and always has been, about balancing competing interests seeking to benefit themselves, and that's as it should be, but the force of government should never be used to reduce competition, kill innovation or support and extend artificial monopolies(垄断)by harming the consumer, the taxpayer and the economy. Policy must breed our new and small businesses or see the as-yet undreamed of innovations that could be our bright future die in infancy.
