前排谢谢构筑 如果还有回忆出洛基 请敲我哦 么么嗒

睡醒了又想起了几道洛基嗷
扔到帖子最后边了~~

谢谢楼主~记忆力太强大了

XDF的2015.08的阅读考古，关于第二篇的，楼主可以看看是不是~
V1【段落大意】：
　　第一段：早在Apollo登月之前，就对月球的形成有三种学说：
　　(1)分裂说fission：地球甩出去的
　　(2)同源说concurrence：和地球一起形成的
　　(3)俘获说capture：独立形成
　　第二段：
　　登月后采集了样本数据和研究成果，发现三种说法都错：
　　(1)假设：如果是fission，crater应该很厚。但是……：反分裂;
　　现在的地月系统应该转得更快(spin)。但是……：反分裂;(Q2)
　　应该还有很多小的卫星体在地球周围。但是……：反分裂;
　　(2)假设：如果是capture，月亮这个独立的星体应该运动的很慢，才会落入地系：反俘获;(Q3)
　　(3)假设：如果是concurrence，它应该具有和地球类似的组成，但是发现……：反同源;
　　(2)证据：月球上的活泼金属(volatile mental)比如锌铅(zinc, lead)含量比地球少很多：反分裂、同源;
　　(4)证据：月球core size很小，和地球不像，也不可能独立小星星：反同源，俘获;(Q4) (Q5)
　　第三段：提出新理论：collision学说。
　　(1)活泼金属少：因为地球和另一个宇宙中的物体擦肩而过，温度高而挥发
　　(2)core小：因为撞偏了;
　　(3)转速：因为有角度撞击，所以变慢了。
　　【题目】：
　　Q1：主旨/结构
　　Q2：如果fission成立的话月球会是什么样子?
　　Q3：如果俘获论是正确的话，如何加强?
　　Q4：哪个会削弱the objection to俘获说capture?(注意!双否定!)
　　Q5：以下哪个点成立会削弱科学家对concurrence的结论?
　　(参考：月球的core其实比科学家预测的更大一些。)

没错就是这篇!!
问题好像都一样..

Paleontologist: About 2.8 million years ago, many species that lived near the ocean floor suffered substantial population declines. These declines coincided with the onset of an ice age. The notion that cold killed those bottom-dwelling creatures outright is misguided, however; temperatures near the ocean floor would have changed very little. Nevertheless, the cold probably did cause the population declines, though indirectly. Many bottom-dwellers depended for food on plankton, small organisms that lived close to the surface and sank to the bottom when they died. Most probably, the plankton suffered a severe population decline as a result of sharply lower temperatures at the surface, depriving many bottom-dwellers of food.

In the paleontologist's reasoning, the two portions in boldface play which of the following roles ?

(A) The first introduces the hypothesis proposed by the paleontologist; the second is a judgement offered in spelling out that hypothesis.
(B) The first introduces the hypothesis proposed by the paleontologist; the second is a position that the paleontologist opposes.
(C) The first is an explanation challenged by the paleontologist; the second is an explanation proposed by the paleontologist
(D) The first is a judgement advanced in support of a conclusion reached by the paleontologist; the second is that conclusion
(E) The first is a generalization put forward by the paleontologist; the second presents certain exceptional cases in which that generalization does not hold good



构筑宝宝 你看看这个选项是不是这个

不是这个嗷 问的都是态度所以其实挺简单的
知道两句都是支持作者并且作者反驳前一个观点应该就可以做了

请问去哪里看xdf的考古？
