※ 引述《henry77ha (fsdae)》之铭言：
: For most people, the left half of the brain controls linguistic capabilities,
大部分的人都是用左脑控制语言能力
: but some people have their language centers in the right half. When a language
有些人则是用右脑 （心里想到“大部分”跟“有些人”，话没有说死）
: center of the brain is damaged,for example by a stroke,linguistic capabilities
当语言中心受损 则语言能力GG
（心理想到“语言中心”跟上句“控制语言能力”的概念
可能不同）
: are impaired in some way. Therefore, people who have suffered a serious stroke
: on the left side of the brain without suffering any such impairment must have
: their language centers in the right half.
因此 左脑受损 语言能力却没事的人 语言中心一定在右脑
结论的争议点是“（这种人的）语言中心在哪里”
结论讨论的对象是“左脑受伤但却没事的人”
: Which of the following is an assumption on which the reasoning in the argument above depends?
是假设题 但先尝试用削弱方向思考 有没有可能漏洞
1. 语言中心受损＝语言能力GG？
2. 左脑受损＝左脑里的语言中心受损？
（如同 美国被轰炸＝纽约一定被轰炸？）
想完开始看题目
: A) No part of a person's brain that is damaged by a stroke ever recovers.
结论的争议点是“语言中心在哪” 跟 “康复与否”无关
: B) Impairment of linguistic capabilities does not occur in people who have not
: suffered any damage to any language center of the brain.
结论的争议点是“语言中心在哪”，跟“破坏会不会发生无关”
: C) Strokes tend to impair linguistic capabilities more severely than does any
: other cause of damage to language centers in the brain.
结论争议点是“语言中心在哪”跟“严重程度无关”
: D) 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.
正好对中我们一开始质疑的第二个点
你要确保左脑受伤一定会伤到左脑内掌管语言的部份，
才能说左脑受伤却没事的人语言中心一定在右脑
因为若是左脑受伤却没伤到语言中心（取非），
则语言中心有可能不在右脑而还是在左脑（削弱），只是没被伤到而已
且讨论主题也切合结论的争点“语言中心在哪”
: E) It is impossible to determine which side of the brain contains a person's
: language centers if the person has not suffered damage to either side of
: the brain.
结论讲的是“已经受伤的人”语言中心在哪，这个选项讨论的是“完全没受伤的人”
: 答案是D 我选了B 请益! 谢谢各位前辈!
看结论后，先厘清争议点跟讨论的对象 很重要噢。
