用英语造句"战士们每年休两次假"

Soldiers take vacation twice a year.
Soldiers take two vacations in a year.

注意:
vacation/vacations的用法
第一句 - 每年两次休假，所以vacation是单数。
第二句 - 一年内休两回假，所以vacation是复数。

Soldiers前面是否要加The，看情况，因为The soldiers似乎有特指的意思，但又不明确，甚至带有点贬义。或写成Our soldiers/The PLA soldiers比较顺口，Our soldiers有亲切感，我们的战士，我们的子弟兵啊。

在准一点，Our soldiers are allowed to take vacation twice a year. (准许之意）

The soldiers take a holiday once every two years.

The soldiers have vacations twice a year.

The soldiers have two holidays every year!
