I'd like to tell you a story about my best friend Jane. Last week in school we had a big fight, and she didn't {#blank#}1{#/blank#} me. It all started when she asked me if she could copy my homework. I asked her why she wanted to do that, and she said that she had forgotten to do hers. I said I didn't think it was a good idea. I said it would start a bad{#blank#}2{#/blank#} and she should do her own work. She got really {#blank#}3{#/blank#} at me and said she didn't want to be my best friend anymore. I said that was OK and that I was sure she would {#blank#}4{#/blank#} it. And she did. Yesterday she told me she was {#blank#}5{#/blank#}. She said it was much better if she did her own work.

Dear Dennis,

    We just want to say thank you for having us before we caught the plane last week. It was a nice evening, and we enjoyed {#blank#}1{#/blank#} Pete and Sarah. With your help we were able to get to the airport with plenty of time. We often tried to get an {#blank#}2{#/blank#} flight than usual, but it wasn't possible.

    We had {#blank#}3{#/blank#} holiday in Spain. We just loved driving {#blank#}4{#/blank#} the countryside, and we often {#blank#}5{#/blank#} to walk round a mountain village. We met {#blank#}6{#/blank#} friends, Bill and Sue, and they invited us to have a meal with them. They wanted us to stay with them, {#blank#}7{#/blank#} we couldn't, as we had already booked two {#blank#}8{#/blank#} in a hotel.

    The weather was nice. There {#blank#}9{#/blank#} so much beautiful sunshine all the time we were there. Leaving Spain was very sad. It made me want to cry.

    Anyway, we're looking forward to hearing from you, and hope to see you {#blank#}10{#/blank#}. Let me know if you're ever in the area. You must call in.

Yours,

Ray

    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.
