Bob was happy. He was at a new school, and 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 student said." Peter was a student here last year. Now he goes to a different school. You look like Peter. Some students think that you are Peter."
Bob wanted to meet Peter. So he got Peter's address and went to Peter's. Peter opened the door. Bob couldn't believe his eyes. He looked really like Peter! Bob and Peter had the same color eyes and the same smile. They had the same black hair. They also had the same birthday. And they were both adopted (领养) by two different families.
At last, Bob and Peter found 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 didn't know about Bob, either.
Their story was put in the newspaper. There was a photo of Bob and Peter next to the story. A young man named John saw the photo and couldn't believe his eyes. He looked really like Bob and Peter! He had the same color 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 they saw each other, they couldn't believe their eyes. Why did John look really like Bob and Peter? You can guess. Bob and Peter are not twins. Bob, Peter and John are triplets.
