jauntily

They are like streetcars running contentedly on their rails and they despise the sprightly flivver that dashes in and out of the traffic and speeds so jauntily across the open country.

这些人犹如街上的有轨电车，满足于在自己的轨道上运行；而对于那些不时出没于车水马龙间和欢快地奔驰在旷野上的廉价小汽车却不屑一顾。

I gave up trying to squash the vest into the size of a matchbox, and it springs jauntily back to shape.

我放弃了想把紧身马甲折叠到一只火柴盒大小的努力。一松手马甲又弹回了原来的松散状态。

We could tell there was no warning from the way he sauntered into the bathroom, singing jauntily to himself in russian.

从他轻松愉快地哼着俄文歌走进浴室的那种逍遥自在的样子看，我们可以断定他没有接到警报。
