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.

求解

请问这道题为什么选B呀？

请问余数可以不是整数嘛？这道题怎么解释？

老师这个问题还没有解答 As引导的句子问题： 第一个句子as...as...是表示链接的内容程度一样吗，翻译起来感觉不太顺。the circumstances翻译成了这些规律和原则，哪些规律和原则？指代的是什么？此外with引导的是伴随状语？那as...as...作什么成分呢 第二个句子insofar查了是adv.在这个范围；到这个程度的意思。insofar as引导的是什么？insofar as the literature analysis is concerned怎么理解呢 第三个句子，四个as...第一个as意思是作为,第二个as意思也是作为？generally accepted as a race in any given region of ethnic competition怎么理解？第三和第四个as,表示和。。。一样，并列的是哪两个部分，什么和什么一样呢，后面the Chinese in California and the Jew in medieval Europe省略了什么

画线部分不理解。more...than..more后面的of the preindustrial European population比the 2 or 3 percent多？the preindustrial European population是不是应该放在investigate后面比较好

所以这一题c选择creating之所以修饰individual是因为这不是一个svo，+doing的形式所以采取的是就近修饰原则吗？

想问一下金老师，这道题c选择og解释里面说的是修饰individual不是reactions呀，您为啥说是修饰reactions呢

请问怎么从第二段看出来作者的观点是enable to enforce property right不是因为arbitrary 而是因为earlier parents often violated copyright law

我画粉色的这个是一个svo+doing形式吗 还是说它跟在that之后就不算一个完整句

请问什么情况下可以跳着修饰呀？
