标题: feifei-103

The brains of identical twins are genetically identical. When only one of a pair of identical twins is a schizophrenic, certain areas of the affected twin’s brain are smaller than corresponding areas in the brain of the unaffected twin. No such differences are found when neither twin is schizophrenic. Therefore, this discovery provides definitive evidence that schizophrenia is caused by damage to the physical structure of the brain.


103. If the statements on which the conclusion above is based are all true, each of the following could be true EXCEPT:


(A) People who lack a genetic susceptibility for the disease will not develop schizophrenia


(B) Medications can control most of the symptoms of schizophrenics share many of the characteristics found in those of people without the disorder


(C) The brains of schizophrenics share many of the characteristics found in those of people without the disorder


(D) It will eventually be possible to determine whether or not someone will develop schizophrenia on the basis of genetic information alone


(E) Brain abnormalities associated with schizophrenia are the result of childhood viral infections that inhibit the development of brain cells


答案:C


题干: could be true,  EXCEPT = must be false (按照老管的方法,找最确定的)


选项(从下到上):


E 完全超出原文,不能判断


C完全超出原文,不能判断


B完全超出原文,不能判断


A超出原文,不能判断D 注意文章第一句:“genetically identical”,选项最后一词“alone”。




那么,根据解说,答案应该是D啊. 从文章中只能所C不确定,没办法判定C就是错的. 而且D中的"genetic information alone "与文章不符合,可以看出D是错的.请NN们指点.谢谢先!

C. 有 s. 病的人和很多没有 s. 病的人有很多相似的特征。

这怎么可能?

我觉得这答案题是D,问的是必然不成立的情况`


D:It will eventually be possible to determine whether or not someone will develop schizophrenia on the basis of genetic information alone 。因为TWINS 的genetic information 相同:第一句话:IDENTICAL。所以不能仅从这来判断是否有病


C:The brains of schizophrenics share many of the characteristics found in those of people without the disorder 。这种情况还是可能的,因为用词是MANY,文中也只是说CERTAIN AREAS OF 。。。SMALLER THAN  CORRESPONDING AREAS 。。所以还是可能有些共同之处的。


恳请大家指点!恳请牛牛解答!困惑中。。

我觉得应该是D,但也只能由排除法得出,也不是很affirmative。




首先排除A, B,E,根据Stimulus Material提供的信息无法判断这三个选项是否正确;


然后排除C,我觉得C是正确的:精神病患者只是在大脑的某些特定部位比正常人大脑的该部位小,所以必然有其它地方是相似的。



所以我觉得答案是D



其中B选项我觉得有语法错误。不过好在它讨论的是medications,和主题有关联的可能性应该很低。

同意iwillfly的说法. D是正确选项.

C: 通常某些病的产生是脑的一部分, 因此脑部有病的人还有和正常人一样的情况. 举个最简单的例子: 脑部有病的人和正常人都会条件反射. 因为脑的一部分功能还控制着神经系统.

看了前辈们的讨论,决定不再纠结这道题了。个人认为这道题根本就是错的,没有一个答案是对的。

答案分析错了,关于could be true EXCEPT我觉得是不是可以这么理解。
Could be true EXCEPT和must be true EXCEPT不是一个解法。Could be true except中,选项如果超出原文范围的,都有可能错,去找那些与原文最为关联的选项。

could be true except = must be false.  This is correct.

So D) is definitely wrong based on the fact that identical twins might and might not have the disease.

标题: 我觉得D为正确选项。
题目已经明确指出“schizophrenia is caused by damage to the physical structure of the brain.” 这说明与gene无关。
