这是虚拟语气的用法。
在It is +形容词(important, necessary, good, essential,right, wrong, better, natural, proper, funny, strange, surprising) +that从句中,谓语动词的虚拟语气用“(should)+动词原形”的结构。如:
It is natural that she (should) do so. 很自然她应该这样做。
before换成end语法上是对的,但含义有所变化。
before the end of the month在这月底前
at the end of the month在这月底
