家庭聚会在英语中被称为 family reunion。这个词的来源可能来自于两个英语单词：family 和 reunion。family 指的是家庭，reunion 指的是重聚，因此 family reunion 就是指家庭重聚。

下面是一些例句：

I'm looking forward to seeing my extended family at the family reunion this year.

我期待着今年在家庭聚会上见到我的大家庭。

The family reunion is a great time for catching up with relatives you don't see very often.

家庭聚会是一个与你不常见的亲戚聚在一起的好时机。

I'm responsible for organizing the family reunion this year.
