这是Martin Luther King的演讲Where do we go from here的一个小段落。

This is where we are. Where do we go from here? First, we must massively assert our dignity and worth. We must stand up amidst a system that still oppresses us and develop an unassailable and majestic sense of values. We must no longer be ashamed of being black. The job of arousing manhood within a people that have been taught for so many centuries that they are nobody is not easy.

【参考译文】：这就是我们的现实处境，从这里我们将何去何从呢？首先，我们必须坚定地维护自己的尊严和价值；我们必须在这个依然压迫我们的制度下挺身而出，树立起坚不可摧而又富有尊严的价值观；我们再也不能以生为黑人而羞愧。几个世纪以来，我们一直被灌输我们是微不足道的，我们是一无是处的，如今，要在这样一个民族之中唤醒其勇气，这绝非易事。

【参考解析】：

第一个that 从句为定从，先行词为a people;

第二个that从句为宾语从句，作teach的宾语。属于teach sb sth结构，sth这里为从句，即宾语从句：

The Bible teaches us that we should love each other.圣经教导我们要彼此关爱。
