Friends: Hi, Betty!

Betty: Wow! You look taller, Ann!

Ann: Yes, last year, I was 135 cm tall. Now I'm 140 cm tall.

Peter: And I'm stronger now. Last year, I only did 12 pull-ups. Now I can do 26.

Betty: That's great, Peter! You look stronger now. Oh, here comes Mary. Hello, Mary!

Mary: Hello, everybody!

Peter: Mary, you look strong, too.

Mary: Do I? Well, I ran every day during the holidays. Last year, I ran 100 metres in 18 seconds. Now I can do it in 15 seconds. I'm faster now.

Ann: And you look lighter, John.

John: Yes, I was 55 kg . Now I'm lighter. I exercised every day, and I swam a lot, too.

Bill: Hi, everybody! How are you?

Betty: Bill?

Bill: I know… I'm heavier than before. I ate a lot and didn't exercise at all during the holidays. I'm also slower now. I was almost late this morning!
