As for old people, some of the applications are hard to use because they didn't grow up with them. They don't have simple models of how they should work, what to do when something doesn't work or where to go for help. We make it as easy as possible to be used for people who are not familiar with the technology.

    I think there is huge potential and we are designing it. The ability to connect to friends, who remember the same movies and news and music, is really important, especially as people get old. They end up in retirement homes and they aren't always close to their friends. Allowing the network to help them connect with friends and family is a really powerful thing.

    My mother is an enthusiastic user of the Internet，although it took me years to get her to use e-mail. She was born with normal hearing, but lost it when she was 3.She was totally deaf for many years, until age 53, when she got ear aids. They work really well. That is a big change for her. But before then, her friends couldn't call her on the phone, so they insisted she use e-mail to communicate with them.

    Young people don't even think of the Internet as technology. It's just there, and they use it. There's been a very interesting change in communications styles between old people and young people. There are some kids who are now in their teens and aren't willing to make phone calls. And they think of e-mail as old-fashioned and slow.

    The reason why teens don't make phone calls seems to be that they don't know what to say. When they call they often stop for a while. They don't know what to say，and there's this silence. On the other hand, texting is considered proper, and it's okay if you don't answer. You might have been distracted. It's not considered rude. But it is considered strange if you're in this kind of voice conversation and simply stop talking.

    Nearly 19 percent of teachers of color(有色人种教师) left their jobs after the 2014-2015 school year. Some left for personal reasons like taking care of their families. But 50 percent said they left because they were dissatisfied with their employment situation, such as poor working conditions, student discipline problems and large class sizes. Thus, taking immediate measures to improve it is our top priority.

    For years, researchers have proved the benefits of increasing the share of minority teachers in schools, especially as our public school system has turned to one that is made up mostly of minority students. Teachers of color, who are more likely than their white counterparts to choose to work in racially diverse( 多 种 多 样 的 ) schools, offer particular benefits to their students. Graduation rates increase among minority students when they are taught by racially similar educators, research shows. They can also serve as positive role models, and their presence reduces the chance of racial discrimination at school.

    The Shanker Institute report suggests that the rate of minority teacher hiring is not the whole problem. The problem is what happens after these teachers enter the classroom. These teachers often work in high-poverty rural schools. They are more likely to have less-desirable working conditions.

    Diversity is a key component to equality and opportunity. Where there's a diverse teaching workforce, all kids thrive. So solutions must be found at once to turn this trend around. Firstly, schools should develop mentorship programs that support minority teachers once they are in the classroom. Secondly, more money should be spent in improving working conditions in these schools. Of course, school headmasters should also be evaluated on their ability to retain teachers of color.

    A good modern newspaper is an extraordinary piece of reading. It's great first for what it contains：the range of news from local crime to international politics, from sports to business, from fashion to science, and the range of comment and special feature(特写) as well, from editorial page to feature articles and interviews to criticism of books, art theatre and music.

    A newspaper is even greater for the way one reads it：never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the text.

    A good modern newspaper offers a variety(多样性) to attract many different readers, but far more than the reader is interested in. What brings this variety together in one place is its topicality(时事性), its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it also mean that much of what appears in a newspaper has no more than transient(短暂的) value.

    For all these reasons, no two people really read the same paper：what each person does is to put together, out of the pages of that day's paper, his own selection and order, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need and without wasting time, demands skill and self-awareness as you change and apply the techniques of reading.

    The bus screamed to a stop in Nazareth, Israel. Five Australian backpackers boarded and struck up a conversation with me. They asked typical travelers' questions—where was I going and why was I traveling alone? My plan was to travel with a friend of a friend, I explained, but when I called her that morning, she didn't pick up and I had no other way to reach her. My stomach was in knots, but I decided to head out anyway, thinking I might run into her if I traveled to Tiberius, where we had planned to go together.

    "Why don't you travel with us?" one of the backpackers offered. They were experienced adventurers who would work for a few months, save, then travel for as long as they could. Their current plan was to explore the Middle East and Europe in three months while working in London.

    It seemed risky to travel with strangers, but my instinct said yes. For the next two weeks, I explored Israel with the backpackers and learned to trust my instincts in all types of new and interesting situations. When they hook a ride, I took the bus, but when they wanted to steal into the King David Hotel's swimming pool, I led the way. The world opened up to me because I chose to travel alone. I joined complete strangers, who become close friends. Years later, one couple from the backpacking group even flew from Sydney to Phoenix to be in my wedding. The trip was such a special experience that it gave me confidence in all areas of my life. Since then, I've backpacked alone across South Africa, sky-dived from 12,000 feet in New Zealand and even moved across the U.S. with no job lined up.

    On my third day wandering in Israel with my new friends, I bumped into the woman I was supposed to meet. Though I was happy she was all right, I was grateful she hadn't picked up the phone.

    Pablo Picasso was an amazing painter who experimented with colour and shape. Picasso wanted to find ways to paint emotions. His paintings opened people's minds and showed there were many ways to express ideas.

    Born in Spain in 1881, Picasso learned to paint at an early age because his father was a painter. At fourteen, Picasso began attending the Academy of Fine Arts in Barcelnoa. Although Picasso did well, his teacher wouldn't let him develop his own style. So he change schools. Though his new teachers praised his work, they still criticized it as being too different. Picasso made up his mind to express himself in his own way.

    Disappointed with his career in Spain, nineteen-year-old Picasso moved to Pairs, where he learned about abstract art. He started copying famous paintings so he could paint in any style. However, an important development in his own style came along when his best friend committed suicide（自杀）. Picasso was so upset that he painted only in blue and gray. He painted the poor and the disabled. This is known as his "Blue Period".

    In 1904, his painting style changed again when he fall in love with an artist's model. He began painting everything with colors of rose, red and pink. He mainly painted artists during this time, called his "Rose Period."

    Picasso's style went through style change as he began to learn African art and geometry（几何学）. Instead of painting with different colors, he used different shapes. His paintings made people surprise because they looked like they had been broken and put back together incorrectly. Everything was geometric and abstract. Picasso's new style became known as "Cubism." Cubism was so unique it became very popular.

Pablo Picasso in most remembered for his Blue, Rose, and Cubist periods. But Picasso never stopped experimenting with painting. His painting styles kept changing until his death at the age of ninety-two.

    The world's richest man might seem to have it all, but Bill Gates has one regret. The self-made billionaire said he felt stupid for not knowing any foreign languages.

    Speaking in his third Ask Me Anything question-and-answer session for online forum Reddit(红迪网), the Microsoft founder said that he wished he spoke French, Arabic or Chinese.

    He said, "I took Latin and Greek in high school and got As and I guess it helps my vocabulary. I keep hoping to get time to study one of these—probably French because it is the easiest. I did Duolingo for a while but didn't keep it up."

    Gates, who is worth $79.3 billion, praised Facebook founder Mark Zuckerberg for surprising an audience in Beijing when he spoke fluent Chinese. "Mark Zuckerberg amazingly learned Chinese and did a Q & A with Chinese students—unbelievable, isn't it?" he said.

    This isn't the first time for Gates to admit his regret over language. He also showed his habits at home and personal insights.

    Last February, Gates said he likes to do the dishes himself—to his own special standards every night and also told the interviewer that his wife, Melinda, would likely want Samuel L. Jackson to play her husband in a biopic(传记片).

    He also admitted that he would pick up a $100 bill if he found it on the street.

    As he took the top spot on Forbes(福布斯) 28th Annual Billionaires list last year for the fourth time, he said he is pretty basic when it comes to spending on clothes and food, but that he enjoys investing in shoes and rackets(球拍) when he plays tennis.

    When asked a life lesson he had to learn the hard way, the billionaire said staying up too late is a habit he is still trying to break. "Don't stay up too late even if the book is really exciting. You will regret it in the morning. Pam is still working on this problem," he said.
