The population in China
   China has the{#blank#}1{#/blank#} population in the world, and about one {#blank#}2{#/blank#} of the people in the world live in China. Because of the large{#blank#}3{#/blank#}  , there is less{#blank#}4{#/blank#} space for each family. And it's difficult for lots of people{#blank#}5{#/blank#}  jobs. The large population also causes many{#blank#}6{#/blank#} difficulties for the whole nation .For example, we're {#blank#}7{#/blank#} of energy and water. Most cities are {#blank#}8{#/blank#}   than before, {#blank#}9{#/blank#} the traffic is much heavier .The large population{#blank#}10{#/blank#} a serious problem.

Not everyone can swim with fish in the ocean. But they can enjoy underwater life in another way-by visiting an aquarium.
There is a very large public aquarium in Atlanta, Georgia. The Georgia Aquarium says it is {#blank#}1{#/blank#} in the world. It has more than one hundred thousand sea animals in thirty million liters of {#blank#}2{#/blank#} . These include two whale sharks —the {#blank#}3{#/blank#} largest fish. And everyone seems to enjoy {#blank#}4{#/blank#} huge public aquariums. They have opened around the world. Visiting an aquarium is a good way for children {#blank#}5{#/blank#} about sea animals. They might even want to start an aquarium at home and join {#blank#}6{#/blank#} of people keeping fish as pets around the world.
We do not really know when people began keeping fish as pets. But people have been interested in fish {#blank#}7{#/blank#} a long time ago. Some say the Chinese kept and studied carp(鲤鱼) and goldfish more than one thousand years ago. The {#blank#}8{#/blank#} Romans kept eels（鳝鱼) as pets . And the Greek philosopher Aristotle(亚里士多德) might be the {#blank#}9{#/blank#} to study sea life, including sharks and dolphins.
Some people say that keeping fish at home in small water tanks called aquarium is very {#blank#}10{#/blank#} today.

    Today my uncle buys a computer for my birthday. It {#blank#}1{#/blank#}a black keyboard and a white mouse. I am very happy {#blank#}2{#/blank#}I can search for information about my homework {#blank#}3{#/blank#}the Internet. I can also listen to music, learn English and go {#blank#}4{#/blank#}on the computer. Do you want to be my friend? Please send emails to {#blank#}5{#/blank#}

    What are best friends like? They must know each other well. They can make fun of each other. They must remember each other's {#blank#}1{#/blank#} .TV host Xie Na and actress Zhao Liying are {#blank#}2{#/blank#}friends. Oct. 16th is Zhao Liying's 30th birthday. Xie Na showed several of their photos on Sina Weibo {#blank#}3{#/blank#} wrote, "Little brother, happy birthday. Wish you have everything you want." Zhao Liying replied to it with a {#blank#}4{#/blank#}pig photo," Thank you, elder brother!" These two have joined many shows, {#blank#}5{#/blank#} Up Idol and Back to Field. They are best friends and call each other "brothers." Once both of them surprisingly wore white clothes in a show. Perhaps they show what best friends are like.

    Every morning my father buys a newspaper on his way to work. Every evening my mother reads magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we{#blank#}1{#/blank#}life without paper or print?

    Paper was first created about 2,000 years ago, and has been made from silk, cotton, bamboo, and since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could{#blank#}2{#/blank#}be produced one at a time by hand and they were expensive and rare. Because there weren't many books, few people learned to read.

    Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. Then more people learned to read. After that, knowledge and{#blank#}3{#/blank#}spread quickly.

    Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD-ROMs or machines,{#blank#}4{#/blank#}MP3 players.

    Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day? I am not sure.
