( 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。

请问当遇到这种完全看不懂不明白逻辑关系的题怎么办？可以帮忙分析一下这篇文章吗

011我是把去银行放进了第一个、第二个、第三个然后分别去算它的可能性，我算出来是10种诶，不太懂为什么答案是12种

请金老师帮忙回答下 七龙珠E卷 34 考点： 并列，时态 我自己选的A， 理由：划线外are often dragged under and drowned的 主语that指的就是seabirds， 语义，并列都符合，虽然用的是encountered但是感觉可以接受 给出的答案C，说长线 devastating 海鸟 are often dragged and drowned. 感觉从修饰结构能接受，但是句意不是很理解

请金老师帮忙回答，七龙珠E卷的 32题 考点： 修饰，分号与逗号 读完句子直间排除了BCD， 保留了A，E,做题时没有注意到分号， 是否因为it appears darker是有完整主谓，E不能直接逗号接从而排除

七龙珠E卷的16题 请金老师帮忙解答： 可以看出考点：修饰，指代，时态 根据副词修饰形容词排除了AB， CDE选项，我能看出考点，但是缺选不对答案，比如我知道考点是指代，但是我无法判断percentage of it这个加上到底好不好， 再比如我能注意到 estimated that, 会认为需要用将来式，但是做题的时候感觉读C更顺，而选择C 实际做题的时候，应该怎么结合看出来的考点提高正确率呢？

请问什么时候用从句，什么时候用svo+doing呢？

请问"and consequently"的意思和作用与“and thus" 或“and also"是一样的嘛

since Robert boyle是什么意思怎么感觉怪怪的？所以这道题就是关注语义形式并列而不是看功能并列嘛？还有就是and also到底可不可以用？
