When we talk about paper, we think of newspapers and books. But there is some paper{#blank#}1{#/blank#}(use) in many other ways. Only half of{#blank#}2{#/blank#} world's paper is used for books and newspapers. Paper , on{#blank#}3{#/blank#}we usually write and draw , is very good for keeping you warm. You have perhaps seen homeless men asleep on a large number of newspapers. In Finland, it is sometimes -40℃ in winter. The farmers wear paper boots in the snow. Nothing could be{#blank#}4{#/blank#} (warm).

    Each year, more and more{#blank#}5{#/blank#} (thing) are made of paper. We have had paper cups and plates for a long time. But now we hear that chairs, tables, and even beds can{#blank#}6{#/blank#}(make) of paper. With paper boots and shoes, you can also wear paper hats, paper dresses, and paper raincoats{#blank#}7{#/blank#}you have used paper cups once, you throw them away and buy new{#blank#}8{#/blank#}(one).

    The latest use of paper seems to be paper houses. These are not small houses for children {#blank#}9{#/blank#}(play) in, but real, big houses for people to live in. You can buy a house with three rooms for about 500 dollars. You can put it up by yourself in a few hours{#blank#}10{#/blank#}you can use it for about five years.

    Recently a really strange thing happened in a middle school in China's Hubei Province. Over 600 students there took part in a "caring for an egg like a baby"{#blank#}1{#/blank#} (active), in which they were asked to keep an egg close at hand for a month{#blank#}2{#/blank#}breaking it.

    "It's hard for parents to bring up their children {#blank#}3{#/blank#} many students just ignore it," said Liu Kang, the school's director. "They should {#blank#}4{#/blank#} (teach) to be grateful to their parents, who have given them life but ask for nothing in return."

    Li Ming is one of the students. His egg didn't break during the month, but he felt   {#blank#}5{#/blank#}(exhaust). "I now understand what great difficulty my parents have had{#blank#}6{#/blank#}(bring) me up. I'll do all I can to make their life easier and {#blank#}7{#/blank#} (comfort) when I grow up," promised the 13-year-old boy.

    {#blank#}8{#/blank#}(luck), about 450 students broke their eggs. Yan Yueming broke his egg after just five days, which made him frustrated. He said, "I can't imagine {#blank#}9{#/blank#} sad my parents would be if there was something wrong with me, their 'egg'! It is now time I {#blank#}10{#/blank#}(do) something in return for their love," said Yan.

    Johann Strauss was{#blank#}1{#/blank#}Austrian composer of light music，particularly dance music and operettas (轻歌剧). He was born in Vienna in 1825. Although his father didn't want him{#blank#}2{#/blank#}(become) a musician, Strauss studied the violin{#blank#}3{#/blank#}(secret) when he was a child. When his father discovered his son was practicing on a violin one day, he gave him a beating,{#blank#}4{#/blank#} (say) that he was going to beat the music out of the boy. But that didn't prevent the boy from becoming one of the greatest{#blank#}5{#/blank#}(composer) of all time. He wrote his first waltz at six. At the age of 19, he decided to devote himself to{#blank#}6{#/blank#}(write) music. He formed his own orchestra and made a successful tour to Europe and soon became famous. The emperor of Austria was so{#blank#}7{#/blank#}(please) with his music that he appointed him the conductor at the court balls of Vienna. It was for these occasions that he wrote some of his most popular waltzes, among{#blank#}8{#/blank#}was the well­known favorite TheBlueDanube. In all，the talented Johann Strauss wrote more than 500 masterpieces. In his lifetime, he was known{#blank#}9{#/blank#}the Waltz King, and was largely responsible for the{#blank#}10{#/blank#}(popular) of the waltz in Vienna during the 19th century.

    Every Wednesday at 7 pm, a group of running enthusiasts from different countries gather at a bar in Shanghai before setting {#blank#}1{#/blank#} on their 5-kilometer run. But this is no ordinary run. These people {#blank#}2{#/blank#} (arm) with trash (垃圾) bags. The members of this group don't simply run for the sake of good health. They do it for the sake of the Earth {#blank#}3{#/blank#} well.

    Called "plogging", this new fitness activity originated in Sweden in 2016 and was introduced to Shanghai in 2018. The term is a combination of the words "jogging" and "plocka upp", {#blank#}4{#/blank#} means "pick up" in Swedish.

    By the summer of 2018 just a few months after Trash Running China was founded, {#blank#}5{#/blank#} (it) WeChat group had grown to include more than 400 runners. To make the activity more fun for both {#blank#}6{#/blank#} (newcomer) and regular ploggers, Trash Running China also {#blank#}7{#/blank#} (frequent) organizes longer weekend runs in the suburban areas. "We want more people to hold small 'plogging' groups and have a {#blank#}8{#/blank#} (responsible) to organize trash running activities in their own neighborhoods," says Eisenring, who founded Trash Running China." 'Plogging' is a way {#blank#}9{#/blank#} (know) the people and the city a bit more," says Robbin Trebbe, one of the {#blank#}10{#/blank#} (late) runners to join the group.

    No one thought that young Albert Einstein would grow up to change the world. He was so slow in learning to speak that he was considered a bit {#blank#}1{#/blank#}(fool).

    Albert Einstein was never happy in school. He answered slowly because he was very thoughtful, and he asked difficult questions, which made {#blank#}2{#/blank#}(he) teachers think that he was trying {#blank#}3{#/blank#}(make) trouble. The strict discipline(纪律)of a German school made him very unhappy.

    However, young Einstein {#blank#}4{#/blank#}(do) learn what interested him, and he was interested in what lay below the surface of  {#blank#}5{#/blank#}(thing). For instance, his father once gave him a compass(指南针). This made Albert curious {#blank#}6{#/blank#} the unseen forces that could keep a compass needle always pointing north. In his teens he read deep in science. He had already started to wonder about the mysteries of {#blank#}7{#/blank#} universe.

    At 17, Einstein entered the Polytechnic Institute in Zurich, Switzerland, {#blank#}8{#/blank#} he studied mathematics and physics. He stayed away from many lectures and did not impress his professors, but he was {#blank#}9{#/blank#}(actual) studying very hard all the time. When he graduated in 1900, he asked to be appointed as an assistant in the physics department but {#blank#}10{#/blank#}(refuse).

    It's so close, and yet it always seemed so far away. {#blank#}1{#/blank#}(get) to the rural district just a few hundred {#blank#}2{#/blank#}(meter) away on the other side of the bay, native people used to have to jump on a boat or drive about 160 kilometers－part of that journey on {#blank#}3{#/blank#}(dust) road.

    Now anyone wanting to get from downtown Maputo, capital of Mozambique, to Katembe, or vice versa, can do so easily, and in a matter of minutes, thanks to the longest twin­tower suspension bridge in Africa, {#blank#}4{#/blank#} hangs over Maputo Bay.

    "Mozambique had long planned to build a bridge linking the north and south of the bay, but nothing came of them because {#blank#}5{#/blank#} a lack of money and technology,"  said Wang Lijun, vice­president of China Road and Bridge Corporation (公司), which built {#blank#}6{#/blank#} bridge.

    The Maputo­Katembe Bridge, {#blank#}7{#/blank#}(open) in November after four years of construction, is part of the Maputo Bridge and Link Roads project which {#blank#}8{#/blank#}(build) by CRBC. It {#blank#}9{#/blank#}(be) 187 kilometers long and serves as an important highway that directly links Maputo to the border with South Africa, to the south.

    "By night, when the lights are on, it's {#blank#}10{#/blank#}(especial) impressive," Wang said, and as a landmark it could help develop tourism and attract overseas investment for Mozambique.
