knees-up

Lie down on your back and bend your knees up please.

请仰着躺下,把腿蜷起来.

OK. Keep those knees up.

好, 膝盖抬高.

It is also a good excuse for a knees-up; specifically, according to a national tradition dating to the "peace teas" held to celebrate the Versailles treaty in 1919, for decking residential streets with Union flags and setting up makeshift tables in the road.

这也是举办一场活跃聚会的好理由，尤其是按照国家传统，可追溯至为庆祝1919年凡尔赛条约签订的“和平茶”，人们用欧盟旗装饰住宅街道并临时在道路上放置桌子。

Let me examine your abdomen. Lie down on your bak and bend your knees up please.

让我检查一下您的肚子, 请仰躺,把腿卷起来.

We'll be having a bit of a knees-up on Thursday evening after work.

星期四晚上下班以后我们要办点庆祝活动。
