27. Which of the following can be inferred from the passage concerning the Sumerians?
A). They were descendants of the Persians.
B). They were the first people to cultivate the valley of the Tigris.
C). They were accomplished musicians.
D).They had the beginnings of an economy.
我不知道选什么,答案是D,我怎么也没找到他们有经济得开端的证据是什么?难道是他们会写字?
35. The fact that the "land is largely the site of erosion" (line 7) is significant because
A). erosion is less destructive than sedimentation
B). fossils are most common in areas subject to erosion
C). erosion contributes to the destruction of skeletal remains
D). few organisms live in areas that experience extensive erosion
我选的是c答案是d
请看下文(原文)
Therefore, organisms must be buried rapidly to escape destruction by the elements and to be protected agents of weathering and erosion.
Marine organisms (thus) are better candidates for
fossilization than those living on the land because the ocean is typically the site of sedimentation, (whereas the land is largely the site of erosion).
注意thus这个单词,意为应此,原因在上一句话,意思很明显:埋得快一点就不会被侵蚀点,这和选项d生存得种类多有什么关系?
45. Why does the author mention “the University of Indiana campus" in line 10-11
A). To provide evidence that intact acorns are hard to find under oak trees
B). To indicate a place where squirrels can aid seed dispersal of oaks
C). To argue in favor of additional studies concerning the destructive force of squirrels
D). To support the claim that squirrels can do great damage to oak stands
请问C和D有什么区别,为什么选C不选D。

我想请教一下27题的D选项是如何推倒出来的呢?我在原文中没有找到答案
原文7-8行,They had invented bronze, ..... out of which they made tools and weapons. They lived in cities,and they had begun to acquire and use capital.我觉得,从这几句话中,能看出他们已经有了初步的经济基础,否则,谈何制造武器,以及acquire and use capital?

45T,D的意思是错的。
C说的是,松鼠有巨大的破坏作用,这和原文是符合的,因为它们很能吃corns
但D说的是,松鼠会对橡树造成巨大伤害,这是和原文不符的,因为实际上松鼠是在帮助橡树繁殖,而并不仅仅是破坏!
