I go ballroom dancing twice a week.

我一个星期跳两次交际舞。

The only aspect that left a bit to be desired was the fact that most students don't know much about ballroom dancing, even though many wanted to brave the occasion or have a go at it.

美中不足的是，由于是我校第一次举办舞会，虽然事先进行了交谊舞教学，但由于大家的底子浅，面子薄，许多同学还是对舞群“身不能至，心向往之”。
