My brother is very busy. He often{#blank#}1{#/blank#}     day and night.

—What do you think of this math problem?

    A road is a bridge between two places. The Silk Road has been a bridge East and West for more than 2,000 years. The Silk Road has been {#blank#}1{#/blank#} included into the UNESCO World Heritage List（世界文化遗产名录）at the 38^th session of the World Heritage Committee in Doha.

    But did you know: the Silk Road is not a single route（路线）! It is a series of {#blank#}2{#/blank#} and cultural transmission（传递）routes. It began during the Western Han Dynasty. The trade route starts from the city of Xi'an in Shannxi Province and  {#blank#}3{#/blank#} in Eastern Europe, near today's Turkey and the Mediterranean Sea. The Silk Road was about 6,500 kilometers long. It went  {#blank#}4{#/blank#} one-fourth of the planet.

    The Silk Road got its name  {#blank#}5{#/blank#} Chinese silk used to be carried along this road. Apart from silk, jade, ceramics and iron went west to Rome. From the west came glass, gems and food {#blank#}6{#/blank#} carrots and sesame（芝麻）.

    The Silk Road was very  {#blank#}7{#/blank#} to both China and the rest of the world. Besides trade, knowledge about science, arts and literature, as well as crafts and technologies was  {#blank#}8{#/blank#} across the Silk Road. In this way, languages and cultures developed and {#blank#}9{#/blank#} each other.

    Today, {#blank#}10{#/blank#} along the Silk Road are great travel destinations（目的地）,such as the Terracotta Warriors in Xi'an and Mogao Grottoes in Dunhuang Gansu.

    Jack's uncle lives in a village. This summer Jack went to stay with him. He {#blank#}1{#/blank#} his holiday there. Every day they went out for a walk and his uncle {#blank#}2{#/blank#} at everyone. Jack didn't {#blank#}3{#/blank#} and asked，“ Uncle George, do you know {#blank#}4{#/blank#} around here?”

    “No,” said his uncle.

    “Then why do you smile at them?” asked Jack.

    “Well, when I smile at someone, if he {#blank#}5{#/blank#} me, he'll be happy. But when I smile at someone, even though he doesn't know me, he'll feel {#blank#}6{#/blank#} and think, ‘Who is that man? Why does he smile at me?' He'll think about these {#blank#}7{#/blank#} all the way, and he will be {#blank#}8{#/blank#}, too. So I give everyone happy {#blank#}9{#/blank#} I think nobody refuses the smiles.”

    “I see, Uncle George. Being kind to others is also be kind to {#blank#}10{#/blank#},” Jack said happily.

    Each nation has many good people who help to take care of others. For example, some high school and college students in the United States often {#blank#}1{#/blank#} many hours as volunteers in hospitals, orphanages (孤儿院)or community( 社区)homes for {#blank#}2{#/blank#}people. They read books to the people in these places, or they just visit them and play games with them or listen to their{#blank#}3{#/blank#}.

    Other young volunteers go and work {#blank#}4{#/blank#}the homes of people who are sick. They paint, {#blank#}5{#/blank#}up or repair their houses, do their shopping or mow (修剪) their lawns (草坪) . For boys who have lost their fathers, there is an organization {#blank#}6{#/blank#}Big Brothers. College students and other men take these boys to baseball games or on fishing tips and help them to get to know things that boys usually {#blank#}7{#/blank#}from their fathers.

    Most children like to have parties for their birthdays {#blank#}1{#/blank#} they can ask their friends to go to their parties. The birthday boy or girl is in beautiful{#blank#}2{#/blank#}. They play games, sing, dance and {#blank#}3{#/blank#}  At the birthday party, the birthday cake is their{#blank#}4{#/blank#}  food. Their parents buy a big cake for{#blank#}5{#/blank#} and there are some candles（蜡烛）on it. Everyone sings the birthday songs and{#blank#}6{#/blank#} "Happy Birthday" to the birthday boy or girl. If you see twelve candles, it is his or her{#blank#}7{#/blank#}  birthday.

    The children usually get gifts {#blank#}8{#/blank#} their friends and parents. They are happy to have them. In{#blank#}9{#/blank#} , children always open the presents after the party. But in England, children open them at once(立刻)and {#blank#}10{#/blank#}  say "thank you". If you have a birthday friend, go and buy a gift for him or her.
