When a wolf was walking near a village, he met a dog. It {#blank#}1{#/blank#} to be a very bony(瘦骨嶙峋的)dog. The wolf had not been hungrier than usual. So he began to move {#blank#}2{#/blank#}towards the dog, while the dog backed away.

    "Let me remind you," said the dog. "it will be an unhappy thing for you to eat me now. Look at {#blank#}3{#/blank#}ribs(肋骨). I am nothing but skin and bone. But let me tell you something in private. {#blank#}4{#/blank#} a few days my master will give a wedding feast (宴会) for his only daughter.

    You can guess how fine and fat I will be on the leftovers(残羹剩饭) from the table.

Then it will be the best time for you {#blank#}5{#/blank#} me."

    The wolf couldn't help thinking how nice it would be to cat a fine and fat dog instead of the bony one. So he went away.

    Some days later, the wolf came back for the promised feast. He found the dog in his {#blank#}6{#/blank#}yard, and asked him to come out and was ready to eat him.

    "Sir," said the dog. "I shall be glad to have you cat me. I will be out as {#blank#}7{#/blank#}as

the porter(看门的人) opens the door."

    {#blank#}8{#/blank#} the "porter" was a huge dog to be very unkind towards wolves, which the wolf knew by a {#blank#}9{#/blank#}experience. He learnt an important lesson {#blank#}10{#/blank#}what you can get when you can get it. So he decided not to wait and ran away as fast as possible.

—I have to hand in the report tomorrow, but I can't        anything to write.

    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.
