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.

求解

请问这道题为什么选B呀？

请问余数可以不是整数嘛？这道题怎么解释？

老师这个问题还没有解答 As引导的句子问题： 第一个句子as...as...是表示链接的内容程度一样吗，翻译起来感觉不太顺。the circumstances翻译成了这些规律和原则，哪些规律和原则？指代的是什么？此外with引导的是伴随状语？那as...as...作什么成分呢 第二个句子insofar查了是adv.在这个范围；到这个程度的意思。insofar as引导的是什么？insofar as the literature analysis is concerned怎么理解呢 第三个句子，四个as...第一个as意思是作为,第二个as意思也是作为？generally accepted as a race in any given region of ethnic competition怎么理解？第三和第四个as,表示和。。。一样，并列的是哪两个部分，什么和什么一样呢，后面the Chinese in California and the Jew in medieval Europe省略了什么

画线部分不理解。more...than..more后面的of the preindustrial European population比the 2 or 3 percent多？the preindustrial European population是不是应该放在investigate后面比较好

所以这一题c选择creating之所以修饰individual是因为这不是一个svo，+doing的形式所以采取的是就近修饰原则吗？

想问一下金老师，这道题c选择og解释里面说的是修饰individual不是reactions呀，您为啥说是修饰reactions呢

请问怎么从第二段看出来作者的观点是enable to enforce property right不是因为arbitrary 而是因为earlier parents often violated copyright law

我画粉色的这个是一个svo+doing形式吗 还是说它跟在that之后就不算一个完整句

请问什么情况下可以跳着修饰呀？
