Sonya and her family have been homeless since she was 3 years old. Over the years, they have moved more than 15times to different shelters around New York City. Moving around was hard on Sonya。At school, Sonya hid her homeless from teachers and other students. She didn't want to be treated differently from other kids.

    In sixth grade, Sonya discovered a way to deal with some of her stress. She began studying dance at her middle school. “IT was a way for me to express myself, instead of just holding everything in,”she explains. Soon, Sonya auditioned（试演）for a summer dance camp run by Alvin Alley, a famous dance company. She was accepted. “I was excited,”says Sonya.

    Dancing became an even more important part of Sonya's life in high school. But things were not going well for Sonya at school. Each time her family moved to a new shelter, Sonya often took care of her younger sisters and brothers. She helped them get ready in the morning and took them to school. They would be on time, but Sonya would be late.

    Worrying about her family kept Sonya from thinking about her own future. That changed the summer after 11^th grade. Sonya learned she would have to go to summer school to graduate. She became determined to succeed, no matter what. “It was a wake-up call,”she says.“I had to focus on school and on myself.”

    Sonya made up the work that she had missed, and finally graduated from high school. No one in her family had gone to college before. But in September 2015, Sonya enrolled in the State University of New York at Potsdam. She plans to become a doctor for kids and to teach dance to children who have disabilities.

    November 11 is Veterans Day in the United States. A "veteran" is anyone who has served in the armed forces. The term "veteran" is not just for those who have served in wars. It describes anyone who has ever been in the army.

    On November11, people hold ceremonies(仪式) and parades(游行) to mark Veterans Day. Public officials take part in the events. Army bands play. And soldiers fire guns into the air to remember those who died in service to their country.

    The history of Veterans Day relates to World War I. Many people at the time called it "the war to end all wars." The United States entered the fighting in Europe in 1917. Over 13 million men and women were reported for duty in the army. World War I ended at 11 o'clock in the morning on November 11, 1918. The following year, President Woodrow Wilson signed an official statement to celebrate November 11th as Armistice Day in the United States. It would be a day to honor the men and women who had served in the U.S. armed forces during the war. In 1926, Congress made Armistice Day a national holiday.

    But new problems were on the way. Soon, everyone knew that World War I would not be the war to end all wars. In all, more than 4,000,000 Americans served in the armed forces during the first World War. And 16 million would serve during the second one.

    Armistice Day in 1945 was a special day in the United States. Germany had surrendered in May 1945 and Japan in August. Most men and women who had served in the war were home. So, instead of honoring just veterans of World War I, Americans also honored veterans of World War II. In 1954, Congress decided to change the name of Armistice Day. The holiday became Veterans Day.

    A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy (精确) and speed, The Telegraph reported.

    Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side.

    The company gave 26 participants（参与者）a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all.

    The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, told The Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... they are going to become more positive about the work."

    However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you.

    I prefer Lynne Truss's phraseology: I am a grammar "sticker". And, like Truss—author of Eats, shoots & Leaves – I have a "zero tolerance" approach to grammar mistakes that make people look stupid.

    Now, Truss and I disagree on what it means to have "zero tolerance". She thinks that people who mix up basic grammar "deserve to be struck by lightning, hacked (砍) up on the spot and buried in an unmarked grave", while I just think they deserve to be passed over for a job—even if they are otherwise qualified for the position.

    Everyone who applies for a position at either of my companies, iFixit or Dozuki, takes a compulsory grammar test. If job hopefuls can't distinguish between "to" and "too", their applications go into the bin.

    Of course, we write for a living. iFixit.com is the world's largest online repair manual (指南), and Dozuki helps companies write their own technical documentation, like paperless work instructions and step-by-step user manuals. So, it makes sense that we've made a strong strike against grammar errors.

    But grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the Internet. And, for better or worse, people judge you if you can't tell the difference between "their" "there" and "they're".

    Good grammar makes good business sense—and not just when it comes to hiring writers. Writing isn't in the official job description of most people in our office. Still, we give our grammar test to everybody, including our salespeople, our operations staff, and our programmers.

    Grammar signifies more than just a person's ability to remember high school English. I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing—like stocking shelves or labeling parts. It is the same with programmers. Applicants who don't think writing is important are likely to think lots of other things also aren't important.

    I took a journey to New York, US several months ago. It was the first time I had been abroad. It was also the first time I had taken a trip by myself. I had great enthusiasm and high hopes, and I wasn't let down.

    It's hard to describe how I felt when I arrived at the airport in New York. Looking at people of different races and nationalities passing by and hearing different languages all around me, I couldn't say anything for a long time. I had never understood the cultural diversity of the US so clearly and closely before.

    The following days were even more impressive. We integrated(融入)into the forest of concrete and cement(混凝土和水泥). We waved to the Statue of Liberty; we looked down at the busy island of Manhattan; we looked at well-known universities—Harvard of ancient Egypt.

    Then we visited some well-known university—Harvard, Yale, Princeton and Columbia—each with its own appealing and time-honored history. But what all these universities have in common is their peaceful academic atmospheres witch you could feel everywhere. I was impressed by the libraries, decorated just like cathedrals(教堂), and the laboratories just next to the classroom. My dream is to return to those places as an international student.

    Finally came our destinations—the Model United Nations conference at the University of Chicago. Students from various countries arrived to act as United Nations delegations and share their opinions about global issues.

    As a non-native speaker, I felt that competing against native speakers was a very tough task. But it was also a rare change to improve my English and I couldn't throw it away. With perseverance and devotion. I got used to talking to other delegations naturally. Although I didn't win any awards, the chairman praised me at the closing ceremony for my excellent performance. That made me feel really proud.

    This trip brought me unforgettable and valuable experiences that will benefit me forever.
