     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.
