Bob was happy. He was at a new school， and students there were friendly. “Hi， Bob!” some students greeted him， but some students said’ “Hi， Peter!” Bob didn’t understand. He asked one 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 is in a different school. You look like Peter. Some students thought that you were 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.

Soon Bob and Peter’s story appeared 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 exactly like Bob and Peter! 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.
