Ben: Hello! My name's Ben.

Alice : Hi. I'm Alice and this is my friend Jennifer.

Jennifer: Hello, Ben. Would you like some sweets?

Ben: No, thanks, Jennifer.

Jennifer: I like sweets and ice cream. You see, I'm heavier than Alice .

Alice : I love food but I also love sports. That's why I'm lighter than Jennifer.

Alice : Can you see the two girls over there? They're running. They're our friends Helen and Doris.

Ben: Which one is Helen and which one is Doris ?

Jennifer: The faster girl is Helen and the slower one is Doris . They both love to run but Doris is slower than Helen.

Ben: Are those boys your friends, too?

Alice : The two boys playing basketball? They're Jeff and Kevin.

Ben: They're very tall, aren't they?

Jennifer: Kevin is shorter than Jeff, but you're right, they're very tall. They want to be basketball players.

Ben: And who are the two boys over there?

Alice : Their names are Mark and Carl. Mark is the…

Ben: Oh, let me guess. Mark is the stronger boy and Carl is the weaker one.

Jennifer: Good try but you're wrong. Carl is stronger than Mark. They like to climb.
