When Regina Spektor moved to the Bronx from Russia as a young child of 9, she could speak no English and her family was so poor that they could afford nothing. Yet she carried with her a love of the piano and music.

     "For me, the thing that I loved the most was playing the piano, so when we left Russia I was so afraid I would forget how to play and I would just find a little table and play my pieces," she told "When you spend your life doing something like playing the piano and then you take that away, it's so surreal."(离奇的)

     Her father, Ilya Spektor, said that, little by little, the family saved enough money to afford their first apartment.

     "I was a photographer and, in six weeks, I found my first job in a big photo lab in Manhattan," he said. On the subway one day, Ilya Spektor spotted a man carrying a violin case. The man also seemed to have an Eastern European accent. A conversation led to a visit and, eventually, Regina Spektor was introduced to Sonia Vargas, a piano teacher. She was a well-known professor who taught piano, took Spektor under her wing and trained her for years, at no cost. "I remember talking to Sonia," Spektor said. "She said that when a student is ready, a teacher appears. So she said that I must have been ready to study piano, and so that's why she came into my life."

     "Immediately, how she played," Vargas said. "You can tell the sound. The sound tell you whether the person loves the instrument, loves the music."

     Much later, while playing her own music and selling a CD that she'd created, Regina Spektor caught the attention of a music producer. The rest is history, complete with concerts around the world and performance in front of the Obamas at the White House.

Regina Spektor greatly appreciated her parents, piano teachers and friends for helping her become the musician she is. “I love the idea that if you're walking toward the world, the world will take some steps towards you,” she said.

    We humans spend about one-third of our lives asleep. This may sound like a lot of time, but it is not wasted. Sleep not only helps us stay healthy but it also helps our brains remember. Our brains need good sleep to remember what we do and learn during the other two thirds of our lives when we are awake.

    Researchers at the University of Wisconsin-Madison have found that sleep helps improve brain performance by shrinking(收缩)synapses in the brain. A synapse is the area where cells pass messages to other cells.

    Scientist Chiara Cirelli is a leader at the school's Center for Sleep and Consciousness. She told the reporter that sleep is when the human brain mixes information it has learned while awake into its general collection of knowledge. Meanwhile, the brain forgets unimportant details. This forgetting is important. It makes space for new learning and new memories.

    Cirelli said that the Centers research began with this hypothesis(假设): We sleep so that our brain can repair and refresh itself. She said the idea seems simple and reasonable. However, testing and discovering how it works has been extremely difficult.

    Synapses are only about 20-40 nanometers(纳米)wide. The team began their study by measuring the size of the synapses to look for changes in these already tiny spaces between nerve cells. Cirelli says the process(过程) is difficult because"all the actual measurements of the synapses have to be done by hand." The team had to wait until improvements in laboratory technology made it possible to see these tiny changes. A University of Wisconsin press release called the research a"huge job." Many research specialists worked for four years to photograph, rebuild and study certain areas of a mouse brain. The report also said the scientists measured 6,920 synapses.

    Cirelli says they found that our synapses shrink as our brains clean themselves during sleep. We wake up refreshed and ready to fill those synapses with new information. The research findings are the result of years of hard work at the University of Wisconsin Madison. The researchers published their findings in the journal Science.

    I grew up with a group of pets. As a mother, I was determined to provide my daughter with the same joyful experiences. Indeed, by the time my daughter was in elementary school, our house was known as "the neighborhood zoo". Now that she is a teenager, we've reduced the number of animals in our home, but we still live with two dogs. I can't imagine life without them.

    Regardless, I have become increasingly uncomfortable with the word "pet". When I came upon the conclusion by the University of Tennessee zoologist Gordon Burghardt that the best we can do for pets is a life of "controlled deprivation (剥夺)", I wished I had never bought Lizzy, our leopard gecko(豹纹守宫). I felt a pit in my stomach when I learned that Lizzy's constant clawing at the glass wall of her tank was most likely a signal of stress. It is perhaps not surprising that she died after only two years, despite our efforts to give proper care.

    The problems with the various small creatures we put into cages and tanks are relatively clear-­cut. More challenging moral questions, in my view, arise in relation to our closest furry friends: dogs and cats. Unlike animals that must spend their entire life in a cage or that must struggle to adapt to a human environment, most cats and dogs have it pretty good. Yet it is likely that our dogs and cats may be suffering in ways we don't readily see, because even the most well meaning owner doesn't always provide what an animal needs.

    It may be hard to recognize the harmful aspects of pet keeping when all we hear is how beloved pets are and how happy they are to be in our company. Advertisements showing golden­-haired children playing with golden-­haired puppies and YouTube videos of cats doing funny things make pet keeping look ever so precious.

    Yet if we really care about animals, we ought to know animals are not toys — they are living, breathing, feeling creatures.

    Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.

    In the early years, these schools were much alike. Only young men went to colleges. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them become ministers or teachers.

    In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history.

    As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.

    Today there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with special fields of learning. There's so much to learn that one kind of school can' offer it all.

    Unemployment in the United States is still high at 6.7％. But for job seekers, especially those with college educations, researchers say finding a job can be as easy as logging(登录)on to a computer. It used to be that looking for a job meant hurrying around, knocking on doors and turning to ads. But that's changing, thanks to the Internet. A new report says, for college graduates, looking for a job is getting easier. More than 80 percent of the jobs are available online.

    At the height of the depression(萧条), in the U. S. the highest unemployment rate was 10％, just a little more than two million jobs were being posted each month. But as the recovery takes hold, the job picture looks increasingly bright.

    That's great news for Hamilton. Only once has he ever applied in person for a job at a shopping mall. He said, "I think my generation—the idea of going door to door, out knocking and saying, hey are you hiring? —like that—doesn't exist anymore…those days are gone. Just go online.''

Kim Dancy recently graduated with a master's degree in Public Policy. She found her dream job as an education policy researcher. But she says finding the perfect job online takes a lot of perseverance. She said, "It can be really frustrating and it takes a long time, but if you applied for enough positions and really do your homework you will get somewhere.

    The report's findings suggest careers in Science, Technology, Engineering and Math provide the greatest opportunities, with salaries that range between $30 to $45 an hour. But for maximum income and satisfaction, workers must be prepared to move and change jobs at least every five years.

    A home science experiment recently took the world by storm. Two teens from Toronto, in Canada, sent a Lego man rising above the Earth and captured their tiny astronaut's trip on film.

    Mathew Ho and Asad Muhammad, both 17, used a weather balloon to launch their plastic lego model 16 miles above the Earth. This is inside a part of Earth's atmosphere.

    The two teens were inspired by a similar project performed by students at the Massachusetts Institute of Technology(MIT). The MIT students had launched a weather balloon with a camera into near space and taken many unusual images of the Earth. Mathew and Asad then spend four months figuring out how to launch their own spacecraft into the space.

    Travelling to space is expensive for NASA, but Mathew and Asad worked hard to keep their costs down. They bought much of their equipment used and even sewed the Lego man's parachute by hand. In total, the project cost only$400.

    "We had a lot of anxiety on launch day because there were high winds when we were going up," Mathew told reporters. They had to pump extra helium(氦)into the balloon so that it would rise quickly and avoid being blown too far off course by the strong winds.

    The toy astronaut's journey lasted 97 minutes before the balloon broke and he fell back to Earth. Mathew and Asad then spent two weekends looking for their spacecraft. It had landed 76miles away from the launch site.

    The student scientists are currently finishing up their final year of high school and applying for colleges. They are also looking into more do-it-yourself space projects.

    "I guess the sky is not really the limit anymore," Mathew told reporters. "We never knew we'd get this far. It's been a lesson for us that hard work pays off."
