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.

作文，感觉这个有点难找，有些地方不知道驳了算不算抬杠，请英吉老师指点一下改善一下我的思路，谢谢！

作文，感觉这个找不到更多点能驳了，请英吉老师赐教！以及马上要考试了，请问作文一定要找四个以上才稳吗？

这个题C选项为什么不可以呀 按照唐老师的方法的话只看了最后一句怎么拍出C呀 希望唐老师能回答一下

2/1 + 3/2 + 5/4 + 8/8 + 12/16 + 17/32 +…到无穷，问和是多少 6 8 10 12 16

May老师，我这个题解出来是纯算数做出来，感觉有点麻烦，有没有比较简便的方法可以做这个题呢？ 谢谢老师

金栩竹老师，这道题为什么要选择to doing 呢？to do 与to doing有哪些区别呢？感觉没怎么见过to doing 的形式。

Tina老师，这个E的those of 没有问题吗？这个指代的是哪里呢？ B哪里有问题呢？C的错误是在of嘛？

Tina老师，这个come在这里是谁的谓语呀，前面efforts 的谓语不是aimed吗？这里也只有一个连词，连词后的account不也是谓语么。

【张慧雯】老师 不好意思，不好意思🤦‍♀️ 刚刚手抖打错字了。 就是这道题，我刚重新看了一会，文章思路大致有了谱，但是这个题要问什么，自己怎么定位到原文这里，不太懂了。其他题中，像这样的，让你找最不可能的，排除东西做的题，也都不太懂🤦‍♀️

请英吉老师看一下我这个作文的思路有无什么不足，打问号的是我不太确定的，谢谢！
