    Bob was happy. He was at a new school, and the other students were friendly. “Hi, Bob!” they said. But some students said, “Hi, Peter!” Bob didn't understand. He asked another student, “Why do some students call me Peter?”
    “Oh, that's easy to answer,” the students said. “Peter was a student here last year. Now he goes to a different school. You look like Peter. Some students think that you're Peter.”
    Bob wanted to meet Peter. He got Peter's address from a student and went to Peter's house. Peter opened the door. Bob couldn't believe his eyes. He looked really like Peter! Bob and Peter had the same colour eyes and the same smile. They had the same black hair. They also had the same birthday. And they both were adopted(领养) by two different families.
    Bob and Peter found out that they were twin brothers. Soon after the boys were born, one family adopted Bob, and another family adopted Peter. Bob's family never knew about Peter, and Peter's family never knew about Bob.
    Bob and Peter's story was in the newspaper. There was a photo of Bob and Peter next to the story. A young man named John saw the photo in the newspaper. John couldn't believe his eyes. He looked really like Bob and Peter! He had the same colour eyes and the same smile. He had the same black hair. He had the same birthday. And he, too, was adopted by another family.
    Later John met Bob and Peter. When Bob and Peter saw John, they couldn't believe their eyes. John looked really like them! Why did John look really like Bob and Peter? You can guess. Bob and Peter are not twins. Bob, Peter and John are triplets(三胞胎).

食物链的理论是美国生态学家林德曼在1942年首先提出的。他曾描述了这样一个场景：这是一个风和日丽的春天，一只彩蝶翩翩飞来落在鲜花上津津有味地吮吸花蜜，冷不防背后划过一道绿色刀影，转眼之间，蝴蝶已在螳螂的绿色大刀下奄奄一息。螳螂正要品尝美餐，蛤蟆出其不意地吐射长舌，一下子把它卷入口中。蛤蟆还没来得及吞咽螳螂，悄悄爬到近旁的长蛇猛地一窜，准确无误地一口咬住蛤蟆。正在这时，盘旋在天空中的鹰一个猛子扎下去用利爪紧紧攫住蛇。在大自然里，这只是一个很普通的场面。
