参考答案【正确答案：C】
推理题。根据关键词limbic system定位到第二段第三句。该句以转折连词but开始，因此需 联系上文来理解这句活的含义。结合上文可知，大脑在快速动眼睡眠（即做梦）中和完全清 醒时一样活跃, 但并非大脑的所有部分都一样活跃, 脑边缘系统（情绪大脑）异常活跃，而前 额皮层（思维和推理的中心地带）则相对平静。下文则引用专家的话进行说明，即“我们从梦 中醒来，或者高兴或者沮丧，而且这些情绪会伴随我们一整天”。关键词emotional, happy Repressed 等都在暗示人的情绪。可见, 该段提到脑边缘系统是为了从大脑结构的角度来说明 梦和人的情绪之间的关系。因此C选项正确。

- 分析下述论证中存在的缺陷和漏洞，选择若干要点，写一篇600字左右的文章，对该论证的有效性进行分析和评论。（论证有效性分析的一般要点是：概念特别是核心概念的界定和使用是否准确并前后一致，有无各种明显的逻辑错误，论证的论据是否成立并支持结论，结论成立的条件是否充分等等。） 地球的气候变化已经成为当代世界关注的热点，这一问题看似复杂，其实简单，只要我们运用科学原理——如爱因斯坦的相对论——去对待，也许就会找到解决这一问题的方法。 众所周知，爱因斯坦提出的相对论颠覆了人类关于宇宙和自然地常识性观念，不管是狭义相对论还是广义相对论，都揭示了宇宙间食物运动中普遍尊在的相对性。 既然宇宙间万物的运动都是相对的，那么我们观察问题时也应该采用相对的方法，如变换视角等等。 假如我们变换视角去看一些问题，也许会得出和一般常识完全不同的观点，例如，我们称之为灾害的那些自然现象，包括海啸、台风、暴雨等等，其实也是大自然本身的一般现象而已，从大自然的视角来看，无所谓灾害不灾害，只是当它损害了人类利益，危及了人类生存的时候，从人类的视角来看，我们才称之为灾害。 假如再变换一下视角，从一个更广泛的范围来看，我们人类自己也是大自然的一部分，既然我们的祖先是类人猿，而类人猿正像大熊猫、华南虎、藏羚羊、扬子鳄乃至银杏、水杉等等一样，是整个自然生态中的有机组成部分，那为什么我们自己就不是了呢？ 由此可见，人类的问题就是大自然的问题，即使人类在某一时期部分的改变了气候，也还是整个大自然系统中的一个自然问题，自然问题自然会解决，人类不必过多干预。
