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.

    One sunny afternoon, a young deer and an old deer were {#blank#}1{#/blank#} under a tree in the forest. Suddenly, in the distance, they {#blank#}2{#/blank#} some sounds of dogs' barking.

    The old deer stood up quickly. He felt nervous and {#blank#}3{#/blank#}. He said to the young deer, "Be quick! It's time to find a place to hide in. The barking dogs are fierce(凶猛的) and they will {#blank#}4{#/blank#} us."

    The young deer laughed and said, "Why should we hide from the dogs? We are bigger and

    {#blank#}5{#/blank#}than them. We can toss(扔)them aside with our big antlers(角). We should fight with them bravely. "

    The old deer admired the {#blank#}6{#/blank#}of the young deer, but he did not believe the young. "We'd better run away now." said the old deer.

    The young deer refused to run away. He decided to fight {#blank#}7{#/blank#} the dogs. As the dogs ran to {#blank#}8{#/blank#}, he put down his antlers and wanted to toss them aside. But he didn't win the {#blank#}9{#/blank#} because there were too many dogs. He was killed by the dogs in the end.

    The young deer lost his life because he didn't know his strength and weakness. We can learn a lesson from the story. Don't be like the {#blank#}10{#/blank#} young deer when we are in danger. We should know our strength and weakness.

    Do animals have their culture? What do we mean by "culture"? Recent years social scientists have begun to ask if culture is found just in humans, or if some animals have their culture too. When we think of culture, we mean a way of life that a group of people have in common(共同的). Culture is the {#blank#}1{#/blank#} and beliefs(信仰) that a country or a group has. It is the way of behaviour that helps people live together. It is also the way of behaviour that makes a group of people {#blank#}2{#/blank#} other groups.

    Our culture makes us lose strength, claws(爪子), long teeth, and other defenses (防卫). Instead we use tools, cooperate(合作) with {#blank#}3{#/blank#}, and communicate with language. But this kind of "culture" can also be found in the lives of some animals. Animals can also make tools, for example. We {#blank#}4{#/blank#} think that the ability to use tools was the dividing line(分界线) between human beings and other animals. However, we have found that is not like this. Some animals can not only use tools but also make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.
