gre阅读高频机经：长江水稻
<p> 背景介绍：在南亚发现了<span word="domesticated">domesticated</span> <span word="Rice">Rice</span>,然后推测南亚是<span word="Rice">Rice</span>的发源地，然后1985年在中国的长江流域发现了很多 <span word="wilder">wilder</span> <span word="rice">rice</span>的遗址，推测生活在中国的先民有可能更早的驯化了<span word="rice">rice</span>。</p><p> 提出旧理论：<span word="rice">rice</span>-<span word="farming">farming</span>最早在长江以南出现</p><p> 提出新理论：认为长江流域的<span word="rice">rice</span>-<span word="farming">farming</span>可以往前推几百年。最后一段讲，1940年调查的<span word="wild">wild</span>-<span word="rice">rice</span>其实主要确实是分布在南方，但是长江流域也有1、2种，所以还是有可能<span word="farming">farming</span>在北方也开始很早滴。然后我觉得这篇文章需要把握的就是<span word="wilder">wilder</span> <span word="rice">rice</span>和 <span word="domesticated">domesticated</span> <span word="rice">rice</span>。搞清楚谁是野生的，谁是驯化的就可以了。</p><p> 题目：三个题考得都是逻辑相关，比如加强消弱什么的。</p><p> 题目1：最能<span word="undermine">undermine</span>长江流域水稻是水稻祖宗的?</p> 题目3：作者是怎样利用<span word="geological">geological</span> <span word="graph">graph</span>还是什么<span word="graph">graph</span>来证明它的观点的。应该是从文章最后一段找，但我感觉文中没有直说，要自己推理。选项里好几个都很接近。</p><p> <span word="Since">Since</span> <span word="the">the</span> 1970<span
