The "One Belt One Road" strategy(策略) proposed by President Xi Jinping has drawn public attention to {#blank#}1{#/blank#} oldest and longest trade route-Silk Road．The term in a narrow sense refers to an ancient overland trade route {#blank#}2{#/blank#} （form） in the Western Han Dynasty．This route stretched 4, 350 miles from Chang's an to western China，central Asia and even to Europe, {#blank#}3{#/blank#} （enable） theses regions to have better communications in diplomacy（外交），business and culture．

    China was the first country in the world to breed silkworms and produce silk fabric．This craft skill reached a {#blank#}4{#/blank#} （fair） advanced level in the Zhou Dynasty．As a major export to Europe， "silk" was used to name this great route by a German geographer．China's silk{#blank#}5{#/blank#} （introduce） into western countries through this old trade route．People were {#blank#}6{#/blank#} （familiar）with his product at the beginning，and made many guesses at {#blank#}7{#/blank#} it was produced．According to the record， the idea that silk was picked from trees was widely accepted by folks in Europe．

    {#blank#}8{#/blank#} （garment服装）made of this fabric were always best sellers，and were considered a social status symbol．Ever the gorgeous Egyptian queen，Cleopatra，was also a big fan of the silk．This fascination led {#blank#}9{#/blank#} an increasing demand for this product，and promoted the {#blank#}10{#/blank#}（develop） of this trading route．

    When {#blank#}1{#/blank#} (learn) to drive, we are told to obey the traffic rules and not to drive our vehicles too fast. {#blank#}2{#/blank#} surprises us is that some young people just enjoy the feeling of driving cars or motorcycles at a very high speed. Jack, {#blank#}3{#/blank#} 18-year-old boy, is {#blank#}4{#/blank#} exception.

    Recently, Jack's father has bought him a car, {#blank#}5{#/blank#} is quite admired by his friends. When he is out in the country, where there are a few people driving and the traffic rules are not strict, this {#blank#}6{#/blank#} (adventure) boy will drive {#blank#}7{#/blank#} (extreme) fast. In towns, however, there is a speed limit, that is, fifty kilometers an hour, but Jack often drives much faster.

    One day Jack was driving through towns when a young policeman, who was new to his work, {#blank#}8{#/blank#} (stop) him and said, "I'm afraid you were driving at a more than fifty kilometers an hour, Sir. Please give me your name and address." {#blank#}9{#/blank#} (look) at the policeman carefully, Jack said to him, "Well, sir, I started my journey less than an hour ago." On hearing this, he didn't know the answer {#blank#}10{#/blank#} Jack's excuse. He thought for a few seconds and then let Jack go.

    A few years ago, famous writer and editor Tom became very ill. His body ached and he felt constantly tired. It was difficult for him to even move around. His doctor told him that he would lose the {#blank#}1{#/blank#}(able) to move and eventually die from the disease. He {#blank#}2{#/blank#}(tell) he had only a one in 500 chance of survival.

    Despite the diagnosis(诊断), Tom was determined to overcome {#blank#}3{#/blank#} disease and survive. He was always getting help from medicine books and some doctors {#blank#}4{#/blank#} gave the ideas of curing his disease. The ideas made Tom {#blank#}5{#/blank#}(think) about the possible benefit of several positive {#blank#}6{#/blank#}(emotion).

    He decided {#blank#}7{#/blank#}(concentrate) on positive emotions as a way to treat some of the symptoms of his disease. “Laugh therapy” became part of his treatment. He arranged time each day {#blank#}8{#/blank#} watching comedy films, reading humorous books, and {#blank#}9{#/blank#}(do) other activities that would draw out positive emotions. Within eight days of starting his ''laugh therapy” program, his pain began to decrease and he was able to sleep more {#blank#}10{#/blank#}(easy). He was able to return to work in a few months' time and actually reached complete recovery after a few years.

    One morning, I was waiting at the bus stop, worried about {#blank#}1{#/blank#}(be) late for school. There were many people waiting at the bus stop, {#blank#}2{#/blank#}some of them looked very anxious and {#blank#}3{#/blank#}(disappoint). When the bus finally came, we all hurried on board. I got a place next {#blank#}4{#/blank#}the window, so I had a good view of the sidewalk. A boy on a bike {#blank#}5{#/blank#}(catch) my attention. He was riding beside the bus and waving his arms. I heard a passenger behind me shouting to the driver, but he refused {#blank#}6{#/blank#}(stop) until we reached the next stop. Still, the boy kept {#blank#}7{#/blank#}(ride). He was carrying something over his shoulder and shouting. Finally, when we came to the next stop, the boy ran up to the door of the bus. I heard an excited conversation. Then the driver stood up and asked," {#blank#}8{#/blank#}anyone lose a suitcase at the last stop?" A woman on the bus shouted, "Oh dear! It's {#blank#}9{#/blank#}(I)." She pushed her way to the driver and took the suitcase thankfully. Everyone on the bus began talking about what the boy had done, and the crowd of strangers {#blank#}10{#/blank#}(sudden) became friendly to one another.
