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.

作文，感觉这个有点难找，有些地方不知道驳了算不算抬杠，请英吉老师指点一下改善一下我的思路，谢谢！

作文，感觉这个找不到更多点能驳了，请英吉老师赐教！以及马上要考试了，请问作文一定要找四个以上才稳吗？

这个题C选项为什么不可以呀 按照唐老师的方法的话只看了最后一句怎么拍出C呀 希望唐老师能回答一下

2/1 + 3/2 + 5/4 + 8/8 + 12/16 + 17/32 +…到无穷，问和是多少 6 8 10 12 16

May老师，我这个题解出来是纯算数做出来，感觉有点麻烦，有没有比较简便的方法可以做这个题呢？ 谢谢老师

金栩竹老师，这道题为什么要选择to doing 呢？to do 与to doing有哪些区别呢？感觉没怎么见过to doing 的形式。

Tina老师，这个E的those of 没有问题吗？这个指代的是哪里呢？ B哪里有问题呢？C的错误是在of嘛？

Tina老师，这个come在这里是谁的谓语呀，前面efforts 的谓语不是aimed吗？这里也只有一个连词，连词后的account不也是谓语么。

【张慧雯】老师 不好意思，不好意思🤦‍♀️ 刚刚手抖打错字了。 就是这道题，我刚重新看了一会，文章思路大致有了谱，但是这个题要问什么，自己怎么定位到原文这里，不太懂了。其他题中，像这样的，让你找最不可能的，排除东西做的题，也都不太懂🤦‍♀️

请英吉老师看一下我这个作文的思路有无什么不足，打问号的是我不太确定的，谢谢！
