( Based on the growth rates of large modern reptiles such as ) the Galapagos tortoise and examination of fossils of juvenile dinosaurs, scientists estimate that the larger dinosaurs probably lived to be between 100 and 200 years old. A. Based on the growth rates of large modern reptiles such as B. On the basis of growth rates of large modern reptiles such as C. Based on the growth rates of large modern reptiles like D. On the basis of growth rates of large modern reptiles, like those of E. Based on the growth rates as those of large modern reptiles like 答案是B，错选了A。科学家基于爬行动物的生长率，估计了恐龙的存活时间。科学家做based on的逻辑主语有错吗？麻烦老师讲解。 (Based on account of various ancient writers) , scholars have painted a sketchy picture of the activities of an all-female cult that, perhaps as early as the sixth century B.C, worshipped a godness known in Latin as Bona Dea "the good goddess". A. Based on account of various ancient writers B. Basing it on various ancient writer's accounts C. With accounts of various ancient writers used for a basis D. By the accounts of various ancient writers they used E. Using accounts of various ancient writers 答案是E，还是错选了A。做题时在AE纠结了好久，因为不确定学者作为“基于不同作家的解释”的主语是不是错的，而且感觉基于要比使用的表达更好，尽管可以确定using的主语是学者，但还是把E排除了，麻烦老师讲解。 因为不知道这两道题是犯了什么错误，所以去有道查了based on 的例句，发现人是可以做主语的：Based on the finding, one might predict that the bank should increase its display and budget. 以及 Based on that representation, the district judge denied a motion to dismiss the new comlaint. 麻烦老师讲解这几个题的区别。

老师好…这道CR题错选A能求解释一下么？谢谢！

请教唐瑭老师：og上的题，答案是D，选了A。不明白D为什么对，是因为最后一句的Although强调的是前半句吗？although一般强调后半句还是前半句？

老师这道题不知道该怎么解！我是这么算的 6!/3!*3!得出来的结果再乘以2，等于40，但答案是30，不知道是哪里算错了，还是我理解错了，希望老师解答！

老师图片里是作文的标题和我在规定时间内写的东西，您看看我错误找全了吗？找错的思维有没有跳跃？第一段和第二段的论证可以这样写吗？以及我每次都是三十分钟压线写完，字数也不多，请老师给我提一些思维和写作上的建议，谢谢！

老师这道题题目有点看不懂，算不到B选项，不知道是题目理解错了还是公式用错了，求讲解

老师能讲解一下这道题吗？

老师您好，这道题的题目有一点看不懂，请问是什么意思以及为什么选d？

老师您好，我想问一下这道题E为什么有利于支持文中观点？

@英吉老师，我最近在看您的录播逻辑网课，您不推荐我们回读。但是我在日常练习的时候做不到读一遍就能弄懂句间关系，或者读第一遍有时候连句子一起都不太清楚。那我们想要练就读一遍就可以了解句间关系的能力，并且用在考场的话，平时可以怎样练习呢？

老师请问这个“or”应该怎么算？
