Dear Malia and Sasha,

    I know that you've both had a lot of fun these two years. You have been to many picnics and had all kinds of junk food your mother and I probably shouldn't have let you eat. But I also know that it hasn't always been easy for you and Mom. So now I want to tell you a little more about why I decided to take our family on this journey.

    When I was a young man, I thought life was all about me—about how I'd make my way in the world, become successful, and get the things I want. But then the two of you came into my world with those smiles and suddenly, all my big plans didn't seem so important any more. I soon found that the greatest happiness in my life was that you were so happy. And I realized that my own life wouldn't mean much if I couldn't make you two happy. In the end, girls, I ran for(竞选)President: Because of what I want for you and for every child in the US.

    I want all our children to go to school so that they can learn and grow. I want them to have the chance to go to college—even though their parents don't have enough money. And I want them to get good jobs.

    I want us to see new technologies and inventions that improve our lives and make our earth cleaner and safer. And I want us to see no difference of different colors and areas because we are all equal.

    I hope both of you will start to give others the chances you've had. You know, this country has given our family so much, so you have to, and really should, give something back. When you are doing something larger than yourself, you will realize how helpful you are.

    These are the things I want for you—to grow up in a world in which you can make your dreams come true. And I want every child to have the same chances to learn and dream and grow and get what you girls have. That's why I've taken our family on this great adventure.

    I am so proud of you. I love you more than you can ever know. And I am thankful every day because you behave so well when we get ready to start our new life together in the White House.

Love，

Dad

    The Silk Road is the name of different roads that long ago connected Europe, Africa and Asia. People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3000 years ago. By the time the Chinese silk trade became important in the world, the Silk Road covered almost 6500 kilometers. It spread from Rome to China, which is from the West to the Far East.

    Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices（香料）,cloth, valuable stones and gold.

    There is a famous old story along the old road. It is said that Roman soldiers（士兵）travelled through central Asia. They started to live somewhere near the ancient Chinese village of Liqian. Some of these Romans married local Chinese women and the story of blue-eyed villages of China was started.

    During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar, Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.

    In modern times, the old Silk Road routes（路线）are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35,000 objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.

    On New Year's Eve(前夕), people in Italy throw"(扔)out all the old things. So there ate chairs, beds, clothes and plates in the streets. In Spain, New Year comes more quietly. Everyone holds a bag of grapes.  When twelve o'clock comes, people start eating the grapes.

    In Japan, people eat noodles on New Year's Eve. This food is said to bring long life. Early the next morning, some families climb Mount Fuji. There they watch the first sunrise(日出) of New Year.
