老师您好能否帮我讲解下下面这个文章考试时该如何读，我读完这种文章压根不知道在说什么，只知道在讲ocean basin形成机制的几种理论。No very satisfactory account of the mechanism that caused the formation of the ocean basins has yet been given. The traditional view supposes that the upper mantle of the earth behaves as a liquid when it is subjected to small forces for long periods and that differences in temperature under oceans and continents are sufficient to produce convection in the mantle of the earth with rising convection currents under the mid-ocean ridges and sinking currents under the continents. Theoretically, this convection would carry the continental plates along as though they were on a conveyor belt (conveyor belt: n. 传送带) and would provide the forces needed to produce the split that occurs along the ridge. This view may be correct: it has the advantage that the currents are driven by temperature differences that themselves depend on the position of the continents. Such a back-coupling, in which the position of the moving plate has an impact on the forces that move it, could produce complicated and varying motions. On the other hand, the theory is implausible because convection does not normally occur along lines, and it certainly does not occur along lines broken by frequent offsets (an abrupt bend in an object by which one part is turned aside out of line) or changes in direction, as the ridge is. Also it is difficult to see how the theory applies to the plate between the Mid-Atlantic Ridge and the ridge in the Indian Ocean. This plate is growing on both sides, and since there is no intermediate trench, the two ridges must be moving apart. It would be odd if the rising convection currents kept exact pace with them. An alternative theory is that the sinking part of the plate, which is denser than the hotter surrounding mantle, pulls the rest of the plate after it. Again it is difficult to see how this applies to the ridge in the South Atlantic, where neither the African nor the American plate has a sinking part. Another possibility is that the sinking plate cools the neighboring mantle and produces convection currents that move the plates. This last theory is attractive because it gives some hope of explaining the enclosed seas, such as the Sea of Japan. These seas have a typical oceanic floor, except that the floor is overlaid by several kilometers of sediment. Their floors have probably been sinking for long periods. It seems possible that a sinking current of cooled mantle material on the upper side of the plate might be the cause of such deep basins. The enclosed seas are an important feature of the earth’s surface, and seriously require explanation because, in addition to the enclosed seas that are developing at present behind island arcs, there are a number of older ones of possibly similar origin, such as the Gulf of Mexico, the Black Sea, and perhaps the North Sea.

提问唐老师，这题错选E，题干最后一句Rexecutive 说赢了bid会给公司带来利润，E选项有bid和price就选了，为什么D有关？E无关？

提问唐老师，这道题完全没有思路，看题干最后一句，跟选项如何对应？

提问唐老师，这道题我的做题思路是：题目说一下选项weaken了作者的一个理论，看题干最后一句，我理解的阅读重心是“从安全层面出发的不充分会导致很多后果”，最后对比选项，因为出现“equipment-storage building”我感觉题干没讲就排除BCE，选D，思路哪有问题？

提问唐老师，488根据题目理解为“B和UEP不同意什么看法”回原文定位左边红框地方，但是感觉读下来b并不支持UEP，就有点懵，求问唐老师这题正确解题思路？489，根据题目在讲B的研究，不太清楚定位哪里，求问这题解题思路？

提问唐老师，492根据“scholars”定位到原文第三段“some scholars”理解那句话的意思为“G在自己建造的一个东西的基础上创造了一个东西”，对比选项选的D，提问老师思路的问题出在哪里？

提问唐老师，先跟您说下我的做题思路，首先看题目理解问题是“作者比较可能同意以下关于mtn的？”然后会原文定位到最后一句，有一个impossible，对比选项选了一个有不可能意思的，选了E。后来对答案选D，想问下老师这个思路哪里出了问题？D中past、today‘s gm提到了吗？

小梅老师，选项2老师说除数要大于余数因此余数是0或1，不能确定，但余数应该不可以为0吧，这样的话选项二可以求出余数是1。选D

唐老师，还有这一道题，我是对比范围大小做的，排除了ABCD选的E，但是答案选D，是因为D中“bank对美国经济的影响”比E中“信用卡的扩张对经济的影响”范围更大吗？

唐老师，这是上一道的题目，上面好像没有发出来。

提问唐瑭老师，题目没有看太懂，只知道是一个bank的反面在south做了个啥现在问bank，会原文定位到红框里最后一句话，最后对比选项选了b，求问老师这道题的解题思路？
