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.

请问唐塘老师此题如何通过对比选项出答案? A有Fail主观 B引号原文内容 E success CD如何选择呢

王文静老师，我想问两道包含be likely to的比较题，第一道我选了a,在abc里面抉择的时候，我觉得a more than没有什么问题，就没去看c了，况且比..多4倍和与...的4倍一样多语义也不一样啊，在a语义没有错误的情况下，不是不应该随意篡改语义吗。而且看到a把are补出来了，用to do还比b用从句连接更加连贯，就选了a。 第二题我选了d,这题我不会，特别是b what我不知道为什么不能指代the patterns of stress

王文静老师，我想请问下这道题目 我看懂了原文：只有可以注射的流感疫苗可以提供，父母不愿意让孩子经历注射的痛苦而孩子也不愿意。但成年人一般会有这个并发症的危险并普遍注射了疫苗。目前一种新的NS的流感疫苗对孩子是有效的，但因为孩子很少会有这个并发症危险，孩子们接种这个新的疫苗不会对社会健康带来很大的好处。我没看出来这个题目有啥逻辑链，我觉的说的很对啊，因为孩子不需要疫苗因此这个新的NS疫苗不会对社会健康带来很大的好处。我无法理解正确答案D。我选E的理由是孩子不需要这个新疫苗，而对大人最有效，也就说明了对孩子大量使用这个疫苗并没有什么好处。

问： 王文静老师麻烦教一下这道题目，我选了b,排除了a,因为我觉得a里面不能用it,1990-2000的经济和农耕文化开始的1000年里面的经济不一样啊，it不是指 between 1990 and 2000 the global economy吗，我觉得要用that.就比如一道小汽车的题目(见下图):由于现代技术的发展，现在的小汽车要比以往任何时候的小汽车都省油。这个小汽车就是不同时代的比较啊。然后c我排除的原因是that which had been时态不对，d it has been这里面的it指的是前面的the growth of the global economy between 1990 and 2000, E名词和主谓比不对等。不知道这样看对吗?

提问： 王文静老师，我想问个关于',＋doing'和and的问题，下面整理的问题，我都是在这个地方出现犹豫或者选错,真的是屡做屡错，字有点多，麻烦老师看下啦 Q849是一个句子＋doing的结构，letting引导的是一个对前面动作进行补充解释的动作，与前面的句子是有关系的，所以不能用and去连接，因为and连的是相互独立的没有关系的动作或者事情 Q851 gives mouth和displace grasses并列，造成的结果用rendering作为引导跟在后面，也算是补充解释 Q862也是句子＋,＋doing作为前面一整个句子的补充解释 但是问题来了，Q858 B选项，south are hunting crops and therefore raising这个为什么能对? and不是连接相互独立的两个部分吗，那therefore就是表示因果关系的啊，这不是矛盾了吗，还是这道题目主要的考点不在这里而在于平行，所以有瑕疵也是可以容忍的? Q 865虽然正确选项B可以通过其他考点排除，但是'overcompensating，growing'为啥不好呢，growing an extra one or two不能作overcompensating的补充解释吗，这里有必须选and不选doing,doing的理由吗？

提问：(上次老师的录音听不见声音，貌似是离话筒太远还是啥原因，麻烦老师再教一次，不好意思啦) 王文静老师，这道题目可以麻烦你讲解一下每个选项吗？句子意思我读懂了，后面选的应该是修饰us stock market的，但是我选不出来。然后如果有一些引申考点，麻烦老师也帮忙拎一下，谢谢

王文静老师，我这道题目不知道要不要用你上课教的补充完整的方法，than是可以补的，但是exceed我就不清楚了，我说一下我的思路 a.rates 不能和other immigrant group去比 b.如果直接看的话，rates 不能和immigrant group 比。但是我如果补足的话，mideast immigrants are exhiting rates of entrepreneurship exceeding virtually every other immigrant group (do) in the...就是主语比较 c.直接看的话rates 对those是对的，但是!上课主谓宾比较第一道例题题目的c选项是错误的，它是这样的:wild animals have less total fat than that of livestock fes on grain and have more fat of a kind thought to be good for cardiac health,错误原因是than后面补全的话就是wild animals have that of livestock逻辑错误。这道题目c选项补全immigrants from the mideast exhibit rates of entrepreneurship exceeding (immigrants from the mideast exhibiting ) those of virtually every other immigrant group in the increasingly diverse united states economy..不是不对吗，我觉得这两道题的c好像啊 D.同B的错误 E.谓语动词单复数错误 请老师帮忙解答一下，谢谢！到底要不要补全，还是直接简单看看就好，到底c为啥在这道题目对，以前的例题又错

陆旭老师，麻烦帮忙看下这道题目的B和E选项，我选了E。这道题目我理了一下: R的人民医疗保障的普及程度比T地高 ,R地大多数病的死亡率比T第低，但是R地男性中死于PC的比率要远远高于T地。问矛盾产生的原因。我就猜测答案一定是指出两个地方的不同之处，才能导致这种情况产生。那么E里面只讲了R地得病的男性很多人是因为没有好好利用这个医疗才死的，的确只说了R地，就是自己和自己比，如果非得说正是因为他们没有好好利用才导致T地的人死得少，那么就过度推理了。我后来想了下，如果R地100个男性里面99个得了这个PC，98个没有好好利用死掉了，那么T地100个男性里面99个得了这个PC，98个人因为没有医疗保障死掉了，这根本没法比。但问题是，B不是也只说了T地吗，T地很多男性无法活到得这个病的年龄，自然男性中死亡率就降低了，但是我怎么知道R地的男性能活到那个时候呢，里面又没有明确指出T与R的对比关系，这是不是也存在过度推理？同时，第一句话在我做题的时候充当什么角色呢，不是premise吗？

陆旭老师，我有一些做过的assumption题目取非的句子搞不清，你能帮忙看下吗(不说这道题目的解题思路，单纯就是取非问题，特别是双重否定或者从句里面有否定词） 1.No part of a person’s brain that is damaged by a stroke ever recovers.---> some part of a person's brain that is damaged by a stroke ever recovers. 2.Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.这个句子我不太会取非，正过来说这个句子就是Impairment of linguistic capabilities occurs in people who have suffered any damage to any language center of the brain.那么我取非是Impairment of linguistic capabilities occurs in people who have not suffered any damage to any language center of the brain. 3.If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them. 取非If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages nothing of them. 4.这题出现两个not The collection fee will not significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out. 我取非直接去前面的not: The collection fee will significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out. 5.这个也差不多 Not all steel producers were unaffected by country A’s newly imposed tariffs. 我取非All steel producers were unaffected bycountry A’s newly imposed tariffs. 6.There are no plants native to western Africa that, if domesticated, could serve as staple food crops. 这个if domesticated是不是可以不管，直接改成There are some plants native to western Africa that, if domesticated, could serve as staple food crops.

陆旭老师，我选了D.请问这道题目D选项怎么理解呢？是可以加强还是无关呢？然后我做这道题目的时候，CE选项觉得比较强烈，AB不是很强烈，D是最不强烈的。希望老师能解答下。还有least strengthen我觉得很难看出来，是找最indirect的那个吗？
