GRE阅读逻辑题求翻译求解释

Fossils of the coral Acrocora palmata that date from the last period when glaciers grew and consequently spread from the polar regions are found at ocean depths far greater than those at which A. palmata can now survive. Therefore, although the fossilized
A. palmata appears indistinguishable from A. palmata now living, it must have differed in important respects to have been able to live in deep water.

　　The argument depends on the assumption that

　　(A) no fossils of the coral A. palmata have been

　　found that date from periods when glaciers

　　were not spreading from the polar regions

　　(B) geological disturbances since the last period

　　during which glaciers spread have caused no

　　major downward shift in the location of

　　A. palmata fossils

　　(C) A. palmata now live in shallow waters in most

　　of the same geographical regions as those in

　　which deep-lying A. palmata fossils have been

　　found

　　(D) A. palmata fossils have been found that date

　　from each of the periods during which glaciers

　　are known to have spread from the polar region

　　(E) A. palmata can live at greater depths where the

　　ocean temperature is colder than they can

　　where the ocean temperature is warmer

Answer 1

Fossils of the coral Acrocora palmata that date from the last period when glaciers grew and consequently spread from the polar regions are found at ocean depths far greater than those at which A. palmata can now survive. Therefore, although the fossilized
A. palmata appears indistinguishable from A. palmata now living, it must have differed in important respects to have been able to live in deep water.
这种珊瑚色藻类的化石随着冰川生长型卜而逐渐从极地向外蔓延，这些化石发现的地方比活的藻类生活芹派的海域要深很多嫌租贺。虽然活的和化石长的像，但是，他们能不能在深水里生活是区分他们的标志。
The argument depends on the assumption that
(A) no fossils of the coral A. palmata have been
found that date from periods when glaciers
were not spreading from the polar regions（在冰川没蔓延时，也没化石发现）
我觉得选这个
(B) geological disturbances since the last period
during which glaciers spread have caused no
major downward shift in the location of
A. palmata fossils（地理灾害没有让化石向下移动）
(C) A. palmata now live in shallow waters in most
of the same geographical regions as those in
which deep-lying A. palmata fossils have been
found（现在藻类生活在这些化石发现地的浅摊）
(D) A. palmata fossils have been found that date
from each of the periods during which glaciers
are known to have spread from the polar region（藻类被发现的日期是每一个冰川被认为从极地蔓延的时期）
　(E) A. palmata can live at greater depths where the
　ocean temperature is colder than they can
　where the ocean temperature is warmer（当海域温度更低，藻类可以生活在更深的地方）

追问

答案是B。

追答

我想了一下，的确是B
题目说要证明这个化石在下面的原因，是化石随着冰川生长下去的
他后面给的条件：这些化石发现的地方比活的藻类生活的海域要深很多。虽然活的和化石长的像，但是，他们能不能在深水里生活是区分他们的标志。
应该说化石不是因为活的游下去 然后变成了化石
B排除另一个原因，说明不是因为geological disturbances使得冰滑下去而下去的，隐含是因为冰生长下去的。
如果A是对的话，并不能说明冰grew之后，那个化石是怎么下去的

Answer 2

珊瑚Acrocora palmata化石遗留下来的最后时期长大,因此蔓延冰川极地发现在海洋深处远远大于那些在答:palmata现在可以生存。
所以,虽然化石
答:palmata区分开来palmata出现答:现在还活着,就必须在一些重要的方面,有著汪敏能在深水中生活。
争论困卖枝取决于一个假设
(一)没有化石珊瑚答:palmata已经发生
发现日期从冰川时期
没有从极地传播
(B)地质扰动自从上次的时期
在传播造成号冰川
主要向下移动的位置上
答:palmata化石
答:palmata(C)现在住在浅水区在大多数
相同的地理区域一样
答:palmata者的化石
发现
(D)答配哪:palmata化石发现的日期
分别从这段时期,冰川
众所周知,在极地地区蔓延
答:palmata(E)能生活在更深处的地方
天气冷海水温度比他们能
在海洋温度更暖和
希望能帮到你!!~ ^_^

Answer 3

此题升轮李有个吵迟很明显的假设，就是认为化石在哪发现桐手，它就一定生活在哪里。
换句话说就是，它死后的化石的位置是不变的。
