GMAT阅读虽然难度较大，但考生只要掌握正确的解题方法就能在短时间内快速提升自己的阅读水平。本文小编为大家带来的是GMAT阅读答题套路真题解析，希望对大家的阅读备考有帮助。
GMAT阅读的重点在于知道全文的中心大意，而无需完全理解短文。选择的答案一定要以文章中公开阐明的观点或暗示的看法为基础。对于陌生的单词，如果不影响理解就跳过去。若确系关键词，则可以从上下文中揣测出其含义。考生可以对文章中的关键地方做出标记，并且要特别要注意文章的论点、论据和一些有关的事实，免得读了后面忘了前面，浪费了时间。答题前要认真审题，切不可在阅读全部选项前就匆忙作答。有些选项与文章的问题似乎有些联系，但后面可能还有更适宜的答案。接下来小编将结合具体文章为大家详细介绍一下：
Scientists long believed that two nerve clusters in the human hypothalamus, called suprachiasmatic nuclei (SCNs), were what controlled our circadian rhythms. Those rhythms are the biological cycles that recur approximately every 24 hours in synchronization with the cycle of sunlight and darkness caused by Earth’s rotation. Studies have demonstrated that in some animals, the SCNs control daily fluctuations in blood pressure, body temperature, activity level, and alertness, as well as the nighttime release of the sleeppromoting agent melatonin. Furthermore, cells in the human retina dedicated
to transmitting information about light levels to the SCNs have recently been discovered. Four critical genes governing circadian cycles have been found to be active in every tissue, however, not just the SCNs, of flies, mice, and humans. In addition, when laboratory rats that usually ate at will were fed only once a day, peak activity of a clock gene in their livers shifted by 12 hours, whereas the same clock gene in the SCNs remained synchronized with light cycles. While scientists do not dispute the role of the SCNs in controlling core functions such as the regulation of body temperature and blood pressure, scientists now believe that circadian clocks in other organs and tissues may respond to external cues other than light—including temperature changes—that recur regularly every 24 hours.

3.文章脉络：
第一段：科学家长期以来认为,人类下丘脑神经集群,称为视交叉上核(scn)控制我们的昼夜节律。那些节奏复发的生物周期大约每24小时与地球自转的周期同步。研究已经证明,在一些动物,视交叉上核控制每日的血压波动,体温,活动水平,和警觉性,以及夜间促睡眠物质的释放。
第二段：此外,人类的视网膜细胞用于传输光信息水平的scn最近被发现。并且进行了实验。科学家们现在认为,生物钟在其他器官和组织可能应对外部线索，除了光线温度变化,每24小时经常复发。
