我觉得我的问题是自己做的时候思路不是很清楚。 我现在有上十月份的机经班，然后我在跟着老师分析的时候我就是比较清楚，然后正确率就比我平时自己做的时候高很多。 我平时做prep之后也会听自主答疑，然后找问题的思路，但是对自己没有很深入。我要怎样才能就是让思路变得更清晰一点呢？ 因为我是大四在读学生，平时除去上课时间，晚上有时间还有平时抽出来的时间可以复习GMAT. 然后我还有一个月就考试了，然后我制定了一下计划，希望老师帮我改一下。 1. 再重新看一遍OG,着重看讲解，搞懂里面的语法讲解，总结出OG里面的语法知识和做题思路。用一个星期。 2. 每天练一篇OG的阅读精读和作文。 3. 第二个星期专项练习 CR, RC,SR,PS,DS. 4. 第三个星期做PREP和GWD， 然后做专项分析。 5. 第四个星期做计时的全 GWD set，模考当天考试的情况，找出这个考试当时可能会出现的问题。

麻烦郭老师帮我看看这几题，没写的或者标红的是完全没思路的，谢谢老师

请问陆旭老师！这里的pattern of number"8"是什么呢？！还有其他的pattern of 3之类的，都没看懂，类似的题目也不会做。谢谢老师指导！

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，我觉得这题条件1/2同时成立可以出结论。 因为条件二:X2＞XY，X2一定是正数，那么右边XY，Y＞0。所以X一定为大于0(因为一个正数不可能＜一个负数)。所以能推出结论选C.

想问一下金老师，句子最后加逗号后面有ed形式的非谓语动词，它的主语是不是可以是主句的主语，也可以是整个主句，还可以是离它最近的一套完整主谓宾的主语？还有如果是逗号加ed形式的非谓语动词在句子中间的话，是直接当做修饰前面的句子的主语还是离得最近的一个名词，还是后面句子的主语呢？
