我知道if是引导后面的状语从句，请问that有什么作用为什么不可省略

译文如下：
我一直告诉我老婆,如果他的（这里指的可能是他们的孩子）身体一直这样长的话,他可能成为一名足球运动员.
that引导宾语从句,说明告诉老婆的内容是.

你是想问什么问题呢？翻译还是句子结构呢？
麻烦补充下问题

我一直在告诉我的妻子，如果他继续像这样成长，他可能会成为一名足球运动员。

我一直跟我老婆说，如果他继续像这样长，他可能会成为一个足球运动员

tell sb. sth. 是固定搭配，后面是一个句子，所以，用that指代。
that 是可以省略的。

如有说不能省略的，请告知原因。我所知道的，是可以省略的，而且，一般都省略。
