Years before the advent of plate tectonics―the widely accepted theory, developed in the mid-1960's, the holds that the major features of Earth's surface are created by the horizontal motions of Earth's outer shell, or lithosphere―a similar theory was rejected by the geological community. In 1912, Alfred Wegener proposed, in a widely debated theory that came to be called continental drift, that Earth's continents were mobile. To most geologists today, Wegener's The origin of Continents and Oceans appears an impressive and prescient document, containing several of the essential presumptions underlying plate tectonics theory: the horizontal mobility of pieces of Earth's crust; the essential difference between oceanic and continental crust; and a causal connection between horizontal displacements and the formation of mountain chains. Yet despite the considerable overlap between Wegener's concepts and the later widely embraced plate tectonics theory, and despite the fact that continental drift theory presented a possible solution to the problem of the origin of mountains at a time when existing explanations were seriously in doubt, in its day Wegener's theory was rejected by the vast majority of geologists. Most geologists and many historians today believe that Wegener's theory was rejected because of its lack of an adequate mechanical basis. Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor. However, as Anthony Hallam has pointed out, many scientific phenomena, such as the ice ages, have been accepted before they could be fully explained. The most likely cause for the rejection of continental drift―a cause that has been largely ignored because we consider Wegener's theory to have been validated by the theory of plate tectonics―is the nature of the evidence that was put forward to support it. Most of Wegener's evidence consisted of homologies―similarities of patterns and forms based on direct observations of rocks in the field, supported by the use of hammers, hand lenses, and field notebooks. In contrast, the data supporting plate tectonics were impressively geophysical―instrumental determinations of the physical properties of Earth garnered through the use of seismographs, magnetometers, and computers. 我选了E considerable overlap前面是despite XXX说明这个是个成就，他和后面的反对W的观点的事情是相反的。所以感觉D说用这个词的目的是解释为啥W理论。请老师辨析DE！谢谢！

这道题感觉像是要找规律，但还是没有思路，想请教一下老师，谢谢

麻烦唐瑭老师解答一下～这道题在做的时候我其实问题有点没读懂，就读了最后一句，然后提取出来的关键点是在讲tax一直在征收but汽油的税收没有增加，只有CE选项提到的汽油，但是C在讲汽油进口是新东西，所以我选了E。想麻烦老师解释一下正确选项C，再告知一下这道题应该看哪句话。谢谢～

这道题答案选E但我选了D，难道这里的land不是动词然后intact不应该用副词吗？求解答谢谢！

麻烦唐瑭老师解答一下～这道题我做对了，但是没太懂，我定位了最后一句，感觉在讲maize和monarch butterfly之间的关系。没太读懂各选项，但只有C提到了这两个东西，所以选了C。麻烦老师讲解一下～

请王文静老师回答一下这个问题，谢谢！具体疑惑附在图二了

麻烦唐瑭老师解答一下～这道题看了题目后我没有回看题干，想问一下题目是不是在说利润增涨和涨价没有关系？我选了D，正确答案C，麻烦老师讲一下CD，谢谢～

这道题选E，我错选了D，请唐瑭老师讲解一下这种类型的题该怎么写？必须看完全文吗？怎么对比选项？希望老师把方法讲得详细一点，谢谢！

请王文静老师解答一下，谢谢1.不太会判断ACD（C是因为the magazines’…consumption to convince…money无法作主语？D是因为with不好所以排除？2. 感觉后半段“出版者说服R地中产去花钱是内政主要部分”和破折号之前部分的句意并列不了

老师我想问一下这道题，从6b=ab不是可以推出a=6吗，有点懵，求解答谢谢老师！

这道题答案选A，请问老师怎么用A推出来呀？我自己总感觉虽然能确定四个数的大小，但是比值大小不太确定
