It ought to be universally made known, by means of education, and for this purpose the best informed amongst us would be required to go back to school, that the uses of our intellectual nature are not to be properly realized, without a just regard to the laws of that perishable frame with which it is connected, that, in cultivating the mind, we must neither over-task nor under-task the body, neither push it to too great a speed, nor leave it neglected; and that, notwithstanding this intimate connection and mutual dependence, the highest merits on the part of the mind will not compensate for muscles mistreated, or soothe a nervous system which severe study has tortured into insanity.

如果对与之相联系的死亡法则重视不够，我们的智慧才能是不能够得到适当的发挥的。因此，应当通过教育使其成为众所周知的常识，为了达到这一目的，在我们中学习最好的人要重返校园。在开发大脑的过程中，我们既不应该给身体分派过多的任务，也不能给它分派过少的任务；不能强行加速，也不能忽略；虽然这两者之间存在着紧密依存的联系。这种大脑最大的优点就是不用为肌肉受虐做补偿，也可以舒缓被高强度的学习折磨得发疯的神经系统。

请教曹老师及其他老师，

1.     It ought to be universally made known, 后面跟了两个that 从句，是吗？

2.     It ought to be universally made known和第一个that被隔开了，放了一个句子，这是什么结构，为什么？

请各位老师各抒己见，谢谢曹老师及其他老师。
