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.

王文静老师您好！这道题目我看不出考点，我做题的思路一个是conclude后面跟by还是with，没想到可以to。然后impose不知道是哪个形式比较好？求老师指教

王文静老师您好，这道题目我做题的时候看到了and想到了可能是考平行，但是我记得之前做题好像and后面再加that的话句子算redudant，that..and that这种结构是固定结构吗？求老师指教，谢谢

麻烦老师帮我解决一下这一题，看ABCD这个走向，它主要是想进一步说明一下w是怎么样的。A主要是错在where 不能修饰society CD主要错在就近修饰W的话，主谓不一致。E答案，犹豫了一下，就是living按照语法规则修饰到yellow也是合理的，所以E被排除掉的理由是从and这个并列上来看，是因为it 没有能指代的名词吗？因为前面不管是YJ 还是SPECIES 或 w都是复数的形式
