The good news bucked us all up.

好消息使我们全都为之振奋。

The boat bucked and heaved beneath them.

小船在他们脚下猛烈颠簸着。

The stallion bucked as he fought against the reins holding him tightly in.

那匹种马四蹄离地狂跳，试图挣脱紧紧拴住它的缰绳。

The horse twisted and bucked and finally dismounted its rider.

那匹马扭动并猛然弓背跃起，使得骑手摔下马。

Once the kids have been bucked off, the game generally dissolves into a raucous bout of wrestling and tickling.

一旦孩子们跃起，游戏就会变成一场喧闹的摔跤和挠痒痒。
