OG48的重大发现

zhushanyi

48. A researcher discovered that people who have low levels of
immune-system activity tend to score much lower on tests of mental
health than do poeple with normal or high immune-system activity. The
researcher concluded form thsi experiment that the immune system
protects against mental illness as well as against physical disease.
The researcher's conclusion depends on which of the following assumptions?
(A)High immune-system activity protects against mental illness better than normal immune-system activity does.
(B)Mental illness is similar to physical disease in its effects on body system.
(C)People with high immune-system activity cannot develop mental illness.
(D)Mental illness does not cause poeple's immune-system activity to decrease.
(E)Psychological treatment of mental illness is not as effective as is medical treatment.
前人的因果倒置我非常同意，但是我还有个问题,原文说low levels of immune-system activity  得分底 结论说,免疫系统能抵抗精神疾病,也能抵抗身体疾病
我觉得原文论据中没有提身体疾病,而结论中给出个身体疾病,那假设应该是把身体疾病和结论联系起来,所以我选了b,

请高人指点一下

 顶一下~~

A，文章只是拿low和normal，high比较，不可以拿high和normal比较。

B,我认为是对的，against mental illness as well as against physical disease可以看出来2者有相似性，（排除法也可以得出）

C，太过绝对。没有依据。

D，immune-system activity 的 decrease 没有提到过。

E和D一样是无关选项

答案是D啊，好象没人质疑的

我想了一下，想这样说服自己。

Mental illness 会让人immune-system activity 下降。如果这样，就不能说immune-system activity 有抗击Mental illness的能力了。

up~~请求NN帮助~~

应该是D, 排除因果倒置

B没有道理, 因为根本没有涉及到题干推论的关系, 只是很片面的一个词AS WELL AS, 说明不了什么

zhushanyi

继续指教！

physical在原文中提及，但是原文只说明mental dieases和mental illness之间联系，但是在结论中却出现了physical，所以把它理解成一道补GAP题，为什么不行呢？
