Once there lived a rich man,{#blank#}1{#/blank#} wanted to do something for the people of his town. But first he wanted to find out {#blank#}2{#/blank#} they were worth his help or not.

    In the center of the main road into the town, he placed a very large stone. Then he {#blank#}3{#/blank#} (hide) behind a tree and waited. Soon an old man came along with his cow. “Who put this stone in the centre of the road?” said the old man, but he did not try to remove the stone.{#blank#}4{#/blank#}, with some difficulty he passed around the stone and continued on his way. Another man came along and did {#blank#}5{#/blank#} same thing; then another came, and another. All of them complained {#blank#}6{#/blank#}the stone but none tried to remove it.

    Late in the afternoon a young man came along. He saw the stone,{#blank#}7{#/blank#} (say) to himself, “The night will be very dark. Some neighbors will come along later in the dark and will fall against the stone. ” Then pushing and pulling with all his {#blank#}8{#/blank#} (strong), the young man began to move the stone ... How {#blank#}9{#/blank#} (surprise) he was! There was a bag of money under{#blank#}10{#/blank#}.

    I am Adam Rouse. I first {#blank#}1{#/blank#} (buy) cannabis from a man in the street and continued to buy cannabis from{#blank#}2{#/blank#} (he) for six months and as a result, I got addicted {#blank#}3{#/blank#} it. One day, the man offered me some crack cocaine, a more {#blank#}4{#/blank#}（power）addictive. When I went back to the man for more crack cocaine, he asked me for a lot of money. I was in terrible pain when I couldn't afford to buy any drugs. {#blank#}5{#/blank#} (get) money, I broke into{#blank#}6{#/blank#} house and stole something to sell for money. The more drugs I took, the more addicted I became. So I had to steal something every day to pay for the drugs. One day, I{#blank#}7{#/blank#}（catch）stealing and sent to the police station. The next day, a doctor came to see me and told me that I could die {#blank#}8{#/blank#} I couldn't stop taking drugs. I took his advice and stopped {#blank#}9{#/blank#}(immediate). Now I work in a center for drug addicts, {#blank#}10{#/blank#} (help) others to stop taking drugs.

    In the age of the smart phone, there seems no reason to ask questions about: the weather forecast, a business's phone number or directions, {#blank#}1{#/blank#} can be easily found on Google, but very often people {#blank#}2{#/blank#}(actual) ask these things by {#blank#}3{#/blank#}(make) a phone call. Your answer may be replied to with a thank­you e­mail. This isn't the first time that great changes {#blank#}4{#/blank#}(take) place in our manners due to technology. In {#blank#}5{#/blank#} late 1870s, when the telephone {#blank#}6{#/blank#}(invent), people didn't know how {#blank#}7{#/blank#}(greet) a caller. Often there is just {#blank#}8{#/blank#}(silent). Alexander Graham Bell, the inventor, suggested that people say "Ahoy", {#blank#}9{#/blank#} finally "Hello" went out. The greeting is now used in everyday face­to­face communications. Try to be respectful no matter who you communicate {#blank#}10{#/blank#}. Just keep it in mind that politeness never goes out of fashion.

    You may not know the name John Smith Pemberton, but you must know the name of his{#blank#}1{#/blank#}(invent):Coca-Cola.

    Pemberton was a US chemist. When he was wounded in the Civil War, lie used medicine to ease the pain and gradually got{#blank#}2{#/blank#} (addict) to it. To light the addiction, he created his own drink by{#blank#}3{#/blank#} (use) leaves of coca and nuts of kola. He named{#blank#}4{#/blank#}," Pemberton's French Wine Coca". In the same year, the local government passed a ban on alcohol. Pemberton had to change the recipe to remove the alcohol.

    In 1886, Pemberton invited Willis Venable to help him perfect his new recipe. They used carbonated water and finally invented a new drink. It had no alcohol{#blank#}5{#/blank#}could still ease pain and clear the mind. Pemberton decided to sell it{#blank#}6{#/blank#}a drink rather than a medicine. In 1887, Pemberton sold part of the stock of his company to As a Candler,{#blank#}7{#/blank#}later created the Coca-Cola Company.

    Nowadays. Coca-Cola has become one of the most popular{#blank#}8{#/blank#}(drink) in the world. The company only offers semi-finished products to partners and won't sell the{#blank#}9{#/blank#}(origin) ingredients (成分).Its secret recipe was kept in the Sun Trust Bank in Atlanta for 86 years until the end of 2011. Since then, it{#blank#}10{#/blank#}(keep) in the World of Coca-Cola center in Atlanta.
