throughout history man has had to accept the fact that all living things must die

为什么要用完成时，这种不属于一般规律用一般现在时不就可以吗？
throughout history man has to accept the fact that all living things must die.
两者有什么区别？

◆这个句子没有使用完成时啊？has to 是have to 这个词组的单数第三人称，不是完成时。

你说的很对，是要用一般现在时，而原句正用的就是一般现在时。！！throughout history man has to accept the fact that all living things must die. has to 是个情态词！！ 再看看别人怎么说的。
