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.

老师请问这个问题如何解答

请Tina老师讲解。这个题目问法第一次遇到，说下面哪个不是削弱。这种问法相当于在问哪个是支持或者无关吗？做题时觉得AB都是与原文逻辑无关选项。CDE都在解释一个城市与另一个相比，心脏相关手术的成本因素不同，感觉都与原文相关，但是也不是削弱。这个题目感觉摸不着方向

请王文静老师解答。我理的逻辑链：因为热的地方容易缺水，且全球变暖让温度更高，所以肾结石病会增加。我选的E，说天气热的地方结石病多，冷的地方少。A选项给我感觉是因果倒置，病多的地方，天气热，反了。请老师讲解这个题的正确解题思路，并且指出我的错误在哪，如何避免

C选项的It为什么是指代不清呀

金老师好，当时看B觉得to conquer 的发起者是登山者，不应是hazards，但是根据including觉得是hazards包括这几个事，E从语法上成了amateur including了，这个Ving找动作发起者的规则这里不适用吗？

请老师讲一下思路

请老师讲下第七题思路。我的理解是条件1可以判断，想要成立则xy的个位数应该是5或者0，这样次方之后依然是5或者0，即xy的个位应该相等，所以答案是No。老师，我是错误理解题意了吗？

徐老师讲下第六题，是用捆绑法吗？做这种题特别没有思路，怎么办？

求问解题思路

请问这两题的解题思路
