One day a lion met a spider, who was just busy making a web. The lion 1 for a while and said, "How clever you are! How did you learn to do that?" The spider answered proudly, "I learned it from my mother."

    "I am just a 2 animal," the spider replied. "I cannot run fast or fly. 3 with my web I can catch flying insects, and I don't even have to run after them."

    The lion then asked, "Could you make a 4 for me? Then I would not have to run after animals either."

    The lion tried to scratch his back, but he could not reach where the spider bit. It itched(发痒)for several days. He remembered the smart spider for a long time.
