Louis Armstrong, the most influential jazz musicians, is considered great not only because of his {#blank#}1{#/blank#} (achieve) but also because of his personalities.

    {#blank#}2{#/blank#} (bear) in a poor family in New Orleans in 1901, instead of {#blank#}3{#/blank#} (commit) crimes to get money like some boys in his situation, Louis would sing on the streets in order to earn a few cents from {#blank#}4{#/blank#} (passer-by).However, at the age of 12, Louis was arrested because of firing a gun into the air at a New Year's Eve party. In a school of problem boys, he was taught to play drums and the trumpet, {#blank#}5{#/blank#} enabled him to find work related with music after he left the school.A well-known musician Joe “King” Oliver noticed Louis and began to teach him about jazz.When Oliver left New Orleans in 1917，Louis took {#blank#}6{#/blank#} his job in one of the best bands in town.

    After becoming famous, Louis would introduce his particular style of jazz to enthusiastic audiences while {#blank#}7{#/blank#} (travel) around the United States as well as Europe.Apart from being a famous jazz musician, he was also an unofficial goodwill ambassador who spoke {#blank#}8{#/blank#} (public) about the rights of black people in America. Despite the fact {#blank#}9{#/blank#} he became rich and famous, Louis Armstrong continued to live a simple live in a working-class neighbourhood.He continued playing and recording until July 6th, 1971, when he died in his sleep at his home in New York.He is still remembered as the most {#blank#}10{#/blank#} (distinguish) musician in the early history of jazz.

    Last October, while tending her garden in Mora, Sweden, Lena Pahlsson pulled out a handful of small{#blank#}1{#/blank#}(carrot) and was about to throw them away. But something made her look closer, and she noticed a{#blank#}2{#/blank#}(shine) object. Yes, there beneath the leafy top of one tiny carrot was her long-lost wedding ring.

    Pahlsson screamed{#blank#}3{#/blank#}loudly that her daughter came running from the house. "She thought I had hurt{#blank#}4{#/blank#}I)," says Pahlsson.

    Sixteen years{#blank#}5{#/blank#}(early), Pahlsson had removed the diamond ring{#blank#}6{#/blank#}(cook) a meal. When she wanted to put the ring back on later, it was gone. She suspected that one of her three daughters — then ten, eight, and six — had picked it up, but the girls said they hadn't. Pahlsson and her husband{#blank#}7{#/blank#}(search) the kitchen, checking every corner, but turned up nothing. "I gave up hope of finding my ring again," she says. She never replaced it.

    Pahlsson and her husband now think the ring probably got{#blank#}8{#/blank#}(sweep) into a pile of kitchen rubbish and was spread over the garden{#blank#}9{#/blank#}it remained until the carrot's leafy top accidentally sprouted (生长) through it. For Pahlsson, its return was{#blank#}10{#/blank#}wonder.

    Josh Snow was a {#blank#}1{#/blank#} doctor in London—so {#blank#}2{#/blank#} , indeed, that he {#blank#}3{#/blank#} Queen Victoria as her personal {#blank#}4{#/blank#}. But he became {#blank#}5{#/blank#} when he thought about helping ordinary people {#blank#}6{#/blank#} to cholera. This was the deadly disease of its day. Neither its cause nor its {#blank#}7{#/blank#} was understood. So many thousands of terrified people died every time there was an {#blank#}8{#/blank#}. John Snow wanted to face the {#blank#}9{#/blank#} and solve this problem. He knew that cholera would never be {#blank#}10{#/blank#} until its cause was found.

    If you're in a hurricane(飓风)-hit area and plan on riding it out, proper {#blank#}1{#/blank#} (prepare) is key. And there is one thing you should have around at all times: a plastic water bottle. Why? When the weather {#blank#}2{#/blank#} (take) a turn for the worse, a water bottle is one of the most useful things {#blank#}3{#/blank#} you have in your home. It might even save your life. Severe flooding caused by a hurricane can make the local drinking water dirty with some {#blank#}4{#/blank#} (danger) substances. {#blank#}5{#/blank#} (avoid) a serious illness, it's best to store plenty of bottled water to drink safely.

    That's pretty obvious, of course. But keep those empty plastic bottles around after you drink, too, {#blank#}6{#/blank#} they have lots of uncommon uses. For example, {#blank#}7{#/blank#} empty water bottle can turn into a water filter(滤水器) if you need to drink from the tap. If your lights go {#blank#}8{#/blank#}, don't go the old-fashioned way with candles; you can rely on your handy plastic water bottles once again. Simply tape a small flashlight to the bottom of the bottle, and {#blank#}9{#/blank#} (it) plastic (and the water inside) will amplify the glow(增强光亮). Then the little light can {#blank#}10{#/blank#} (use) to light up a room or send signals to rescue personnel.
