It was a slap-happy March evening.

这是一个令人陶醉的三月之夜。

The baby was born a month ago but Mark is still slap-happy about it.

小宝宝是一个月前出生的，但是马克至今还乐得晕呼呼的。

Neither slap-happy comedy nor aggressive action fare, the Beaver is a somber, sad domestic drama featuring an alcoholic in acute crisis.

既非无厘头的喜剧也非动作片，《海狸》是一部严肃的，伤感的室内剧，它表现了严重危机下的酗酒者。

Wip off that full-of-doubt look, slap on a happy grin.

抹去你的满脸疑惑，挂上开心的笑容。

If you're happy and you know it slap your knees!

如果你快乐并且你知道，就拍拍你的膝盖。
