Eg. the children are having a frolic on the lawn .
孩子们正在草地上嬉戏玩耍。
They had a frolic in the country .
他们在乡村度过了一段欢乐的时光。
And only one in five children live within walking distance ( a half-mile ) of a park or playground , according to a 2010 report by the federal centers for disease control , making them even less inclined to frolic outdoors .
