OG-紫皮-CR-07

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 people with normal or high immune-system activity.The researcher concluded from this 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 systems.
(C)  People with high immune-system activity cannot develop mental illness .
(D)  Mental illness does not cause people's immune-system activity to decrease .
(E)  Psychological treatment of mental illness is not as effective as  is medical treatment.

分享下偶的想法 

low levels of immune-system activity 相对 high level  来说 脑力健康方面得分低

结论: immune system protects against mental illness as well as against physical disease.

意思就是low levels of immune-system activity致使 脑力健康方面得分低


        
A  文中是比较 low levels 与 normal or high levels,A却比较normal levels and high levels,无关比较

B  文中是说 immune system 对mental illness and physical disease的影响,B选项反过来说,而且说的不是immune system而是body system. 无关

C  把选项取非。People with high immune-system activity can develop mental illness .对原文起不到削弱作用。排除

D  取非。 Mental illness cause people's immune-system activity to decrease . Mental illness 影响了immune-system activity levels,削弱了原文所说的是由于immune-system activity 影响Mental health.

E  明显的无关比较。

ASSUMPTION 题一般采用取非,如果某选项能够weaken原文,就是答案。屡试不爽嘿嘿

ya.

我觉得A、B、D是可以直接排除的,

C的话,绝对化了,肯定也不不正确,

但是我不明白为什么D是正确的,

如果取非的话,意思差不多是和结论相反了,

这就是Waken的效果吗?

D取非不是和原文结论相反啊,

是让结论不成立,这就是削弱的效果。

因果倒置的削弱,是比较TRICKY的一种
