In many middle schools of the US, when the P.E. class begins, the students rush into the gym1. They are not crazy2 for basketball or table tennis. They are crazy for a new thing—a machine3. They can dance with this machine and learn to dance from it.
Such machines can be found in schools in over ten US states. Students can get exercise while they dance with them. They can also do this dance with partners4. They like it very much. In the past, they could only play with dancing machines at the video game room5. At first, the parents were not happy that their kids were dancing at school. But after they learned that dancing is a good way to get exercise, they became6 happy.
One P.E. teacher says, "They never run for basketball like this."
