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.

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？
