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.

    Global warming is one of the most serious problems facing humans and greenhouse gases are the main cause of it. Greenhouse gases are produced not only by industry but also by individuals (个人). People use energy to drive cars, make homes {#blank#}1{#/blank#}(comfort) and grow and transport food. Finding{#blank#}2{#/blank#}(solve) to the problem of greenhouse gases is not only a political subject but an individual one as well.

    Look for ways {#blank#}3{#/blank#}(reduce) energy at home. Turn off electrical appliances (家用电器) that you are not using. Replace your light bulbs with energy-efficient light bulbs.

    Eat locally. A lot of energy{#blank#}4{#/blank#}(use) to transport food over long distances,{#blank#}5{#/blank#}burns much fuel. Much of the same food may be grown on local farms. Shop at your local farmers, market. Plant your own vegetable garden.

Make your house {#blank#}6{#/blank#}eco-friendly one. Put a sweater on to keep warm rather than turning the heating on. Plant a tree to provide shade in summer so you don't have to use an air conditioner.

    Reduce and recycle. Be careful {#blank#}7{#/blank#}the products you buy. Recycle all paper, plastic, glass and aluminum (铝) cans.{#blank#}8{#/blank#} (when) you go shopping, please choose items that come with small packaging and that {#blank#}9{#/blank#}(be) reusable. Use your own canvas bags for shopping instead of plastic or paper bags.

    Be energy-conscious of transportation. Walk, ride a bike {#blank#}10{#/blank#}take a bus instead of driving.

    We all know that the Friday after Thanksgiving means a mad dash to the shopping centre for ridiculous sales. But how did this bargain shopping get {#blank#}1{#/blank#}(it) start?

    In fact, the first Black Friday had nothing {#blank#}2{#/blank#} (do) with Thanksgiving or shopping. The origin of Black Friday as we know it today started in Philadelphia during the 1950s and 1960s. Crowds of people would come to town the day after Thanksgiving for the annual Army­Navy football game to be held the {#blank#}3{#/blank#} (follow) Saturday. Streets and {#blank#}4{#/blank#} (store) were always crowded, which was great for business but made easy­pickings for shoplifters (行窃者). Local police called this “Black Friday”. Not only did they have to deal with extra traffic {#blank#}5{#/blank#} shoplifting, but they had to work extra hours and couldn't request the day off.

    The term didn't go national {#blank#}6{#/blank#} the late 1980s, but the {#blank#}7{#/blank#} (explain) changed. While shopkeepers {#blank#}8{#/blank#} (general) suffered financial losses most of the year, the increase of holiday shoppers marked the first day of real profit. In traditional accounting (会计) practices a few years ago, losses {#blank#}9{#/blank#} (record) in red ink, and profits in black ink. So the day after Thanksgiving, {#blank#}10{#/blank#} companies go “into the black” and make a profit, became Black Friday.

    If {#blank#}1{#/blank#} (give) the choice, a great many people would change at least one aspect of their appearance. They would request a doctor to give them a straighter nose, {#blank#}2{#/blank#} (big) lips, and so on.

    Firstly, one's appearance is{#blank#}3{#/blank#} or her parents' blessing. After breast enlargement surgery, many women look sexier than before. {#blank#}4{#/blank#}, many of them are later diagnosed with mammary diseases. The more serious effect is {#blank#}5{#/blank#} they risk {#blank#}6{#/blank#} (be) unable to breast-feed. Secondly, the advocating {#blank#}7{#/blank#}such a practice will mislead people in the{#blank#}8{#/blank#} (judge) of beauty. The concept of beauty is quite rich in its content. It should include many virtues like honesty, diligence, and so on, which should form the real mainstream of our spiritual life. The practice and the debates about man-made beauty will confuse those who are to develop {#blank#}9{#/blank#} correct concept of beauty.

    Concerning the above possible {#blank#}10{#/blank#} (harm) the practice may bring about, I am strongly against it and advocate seeking true and natural beauty. Besides, people, especially women, should lay more attention on the cultivation of their inner hearts. The inner beauty outweighs the outside beauty in the long run.
