— No, not at all.

    Have you ever heard of friendships among animals? At a zoo in Germany, an unusual friendship developed {#blank#}1{#/blank#} a cat and a bear.

    No one is quite sure how the friendship first began. One day, some {#blank#}2{#/blank#} (worker) in the zoo noticed a black cat was in the bears cage(笼子), and the two animals were playing together peacefully. They were surprised {#blank#}3{#/blank#} well the small cat seemed to get along with the large bear. The bear keeper allowed the cat to stay with the bear, And later the pair and their unusual friendship {#blank#}4{#/blank#} (become)a hot topic at the zoo.

    After several years, a new cage {#blank#}5{#/blank#} (build) for the bear. However, the cat was still in the same cage, so it walked around {#blank#}6{#/blank#} (angry) and cried to be with the bear. The bear keeper finally took pity on the cat {#blank#}7{#/blank#} let it stay with the bear. The cat and the bear got {#blank#}8{#/blank#} (close) than before. They often sat together and shared meals in {#blank#}9{#/blank#} sun.

    Sometimes it may be natural for animals {#blank#}10{#/blank#} (have) their own ideas about who would make a good friend. These may surprise humans, who usually expect animals to form relationships with others of the same species.

    About ten years ago when I was at university, I worked at my university's museum. One day {#blank#}1{#/blank#} I was working in the gift shop, I saw two old people come {#blank#}2{#/blank#} with a little girl in a wheelchair (轮椅).

    As I looked closer {#blank#}3{#/blank#} this girl, I realized she had no arms or legs, just a head, neck and body. She was {#blank#}4{#/blank#} (wear) a little white dress. When the old people pushed her up to me, I was looking down at the desk. I turned my head and gave {#blank#}5{#/blank#} (she) a smile. As I took the money from her grandparents, I looked back at the girl, who was giving me the cutest, {#blank#}6{#/blank#} (happy) smile I had ever seen.

    Just at that {#blank#}7{#/blank#} , her physical handicap (生理缺陷) was gone. All I saw was this beautiful girl, whose smile just impressed me {#blank#}8{#/blank#} almost gave me a completely new idea of what life is all about. She took me from a poor, unhappy university student and brought me into her world, a world of smiles and love.

    That was ten years ago. I'm a {#blank#}9{#/blank#} (success) business person now and whenever I feel frustrated and think about the trouble of the world, I will think of that little girl and the unusual lesson about life that she {#blank#}10{#/blank#} (teach) me.
