The private automobile (私家车）has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.

    For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.

    Family life has been affected（影响）in various ways. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can't keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims（受害者）of such accidents have formed an organization called MADD (Mothers Against Drunk Driving). These women want to prevent further tragedies (悲剧）. They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends.

    For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sign of becoming an adult. Altogether, cars mean very much to Americans.

    You may not  have heard of Ashoka,  but for the past 27 years,this association, founded by Bill Drayton, has fought  poverty (贫穷)and sickness, promoted education and  encouraged small businesses. To support these worthy causes, Ashoka provides money for the world's most  promising "changemakers" seeking to solve (解决) urgent problems and would like to create a  world in which every citizen is a changemaker.

    Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy,  contributing adult. In fact It is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city ,helped local farmers and provided an income for poor people there .

When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka's streets, Attracting tats and disease , they discovered that 80% of it was natural waste . So they educated the poor people in the city to compost (把……制成堆粪)this waste . They knew that they would have a market for the end product because local farmers were struggling with chemical ferntilisers (化肥) which were expensive and had reduced the natural minerals in the soil over the years . At first , they were refused ,but once they were able to persuade them that there was money to be made , the project took off. In 2009 sales were $14,000.

    Drayton is optimistic that in ten years Ashoka will be making really serious ,practical progress in bringing about social change by changing the way we look at economic development.

    Hummingbirds (蜂鸟) are very small birds. This small bird is quite an acrobat (杂技演员). Only a few birds, such as kingfishers and sunbirds, can hover, which means to stay in one place in the air. But no other bird can match the flying skills of the hummingbird. The hummingbird can hover, fly backward and fly upside down!

    Hummingbirds got their name because their wings move very quickly when they fly. This causes a humming sound. Their wings move so fast that you can't see them at all. This takes a lot of energy. These little birds must have food about every 20 minutes to have enough strength to fly. Their favorite food is nectar (花蜜). Nectar is the sweet water deep inside a flower. Hummingbirds use their long, thin bills to drink from flowers. When a hummingbird drinks nectar, it hovers in front of a flower. It never touches the flower with its wings or feet.

    Of all the birds in the world, the hummingbird's colors are among the brightest. Some are bright green with red and white markings. Some are purple. One kind of hummingbird can change its color from reddish-brown to purple to red!

    The hummingbird's nest is special, too. It looks like a small cup. The inside of the nest is very soft. This is because one of the things the mother bird uses to build the nest is the silk from a spider's web (蜘蛛网).

Dear 17-year-old self,

    When your Laker dream comes true tomorrow, you need to figure out a way to invest in the future of your family. This sounds simple, and you may think it's a no-brainer, but take some time to think on it further.

    I said INVEST.

    I did not say GIVE

    Let me explain.

    Purely giving material things to your siblings（兄弟姐妹） may appear to be right decision. So you buy them a car, a big house, pay, all of their bill. You want them to live a beautiful comfortable life, right？

    But the day will come when you realize that as much as you believed you were doing the right thing, you were actually holding them back.

    You will come to understand that you were taking care of them because it made YOU feel good, it made YOU happy to see them smiling and without a care in the world﹣and that was extremely selfish of you. While you were feeling satisfied with yourself, you were slowly eating away at their own dreams and ambitions. You were adding material things to their lives, but subtracting the most precious gifts of all.

Invest in their future, don't just give.

    Use your success, wealth and influence to put them in the best position to realize their own dreams and find their true purpose. Put them through school, set them up with job interviews and help them become leaders in their own right. Hold them to the same level of hard work and dedication that it took for you to get to where you are now, and where you will eventually go.

    I'm writing you now so that you can begin this process immediately, and so that you don't have to deal with the hurt and struggle of weaning（断绝） them off of the addiction that you facilitated That addiction only leads to anger, hatred and jealousy from everybody involved, including yourself.

    As time goes on, you will see them grow independently and have their own ambitions and their own lives, and your relationship with all of them will be much better as a result.

    Trust me, setting things up right from the beginning will avoid a ton of tears and headache, some of which remains to this day.

Much love

     Fermat's Last Theorem Simon Singh

    In 1963 a schoolboy called Andrew Wiles reading in his school library came across the world's greatest mathematical problem: Fermat's Last Theorem ( 定 理 ). First put forward by the French mathematician Pierre de Fermat in the seventeenth century, the theorem had baffled and beaten the finest mathematical minds, including a French woman scientist who made a major advance in working out the problem, and who had to dress like a man in order to be able to study at the Ecole Polytechnique. Through unbelievable determination Andrew Wiles finally worked out the problem in 1995. An unusual story of human effort over three centuries, Fermat's Last Theorem will delight specialists and general readers alike.

    When I was small, my mother and I would walk to our local library in Franklin Square. As we didn't always have access to a reliable car, walking hand in hand was the most convenient way to get anywhere. It was at story time for children that both my mother and I made lasting friendships.

    Today, I am fortunate to live around the corner from the Cold Coast Public Library in Glen Head and a short walk to the Sea Cliff Children's Library. My 18-imonth-old son, Colin, and I find ourselves in Sea Cliff several times a week, meeting and making friends. Well, that is what many people don't understand-a library is more than books; it's a community.

    Sure, the library in Franklin Square was the place where I was introduced to Judy Blume novels. But it was also the place where I got my first email address in 1997. At the library, friends and I learned how to research colleges and search for scholarships on the Internet. The library was the place where we sometimes giggled(咯咯笑)too loudly, and where the librarians knew us by name. Their knowing our names wasn't a bad thing. When I came home from my first term at Binghamton University, Mary LaRosa, the librarian at the Franklin Square library, offered me my first teaching job.

    I now teach reading at Nassau Community College. My students are often amazed that they can check out books via their smartphones and virtually(虚拟地)visit a variety of Long Island libraries. The app used by Nassau and Suffolk county public libraries, as well as the college library, makes their homework easier by helping them find resources. Even though they can't always easily visit their local libraries, the library is always with them.
