船上有一个游泳池，是船员们在船底的即兴之作，我们在那儿游过。

There was a swimming pool; the crew had improvised it at the bottom of the ship. We swam in it.

也有充满在行为之间的间歇的喜剧行为，即兴之作若干，和DJ音乐。

There were also comedy acts, impromptu skits, and DJ music to fill the lulls between acts.

另一方面，BLT的堂兄妹，总会三明治（鸡肉夹心三明治），如同十二小节的蓝调-是一次即兴之作的引导者。

The BLT's cousin, on the other hand, the Club Sandwich, is like 12 bar blues - a guiding framework for extemporisation.

今天突然想起了这首算得上是即兴之作的钢琴曲，很搞笑，想了很久都没想起来怎么弹，今天终于想起了。

Today I suddenly have remembered a piano piece that sounds like an impromptu, Very interesting. But I forgotten how to play, Today finally remembered.
