双解例句
小知识
Always round, often bouncy, a ball is a vital part of many games and sports, from soccer to four square to ping pong.
The most common ball is the kind you hit, kick, bat, or duck and avoid on a playground, court, or field. In fact, most sports involve a ball in one way or another. Another fun kind of ball is a grand party that usually includes dancing, food, live music, and guests dressed up in glamorous clothing. These two meanings have different origins — the “fancy dance” kind of ball comes from a Greek root, ballizein, “to dance or jump about.”
