想接着问个问题,既然假设是取非削弱,那么c选项
取非也可以削弱啊,为什么不可以
还有一个问题,关于因果关系的题目,新东方有特别拿出来讲过,但是我不太会分辨什么样题目属于这种关系得题目,一定是先说结果再说原因的吗,倒过来可以马,比如题目中有reason等词,我记得讲义上在说这种题目的特征时,还提到conclusion这个词,可是我觉得那应该引出结论的啊,怎么是说原因的呢?就像这道题一样。
方便起见,题目再帖一次
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.
48.
The researcher concludes from the association of low immune-system activity with low mental-health sores that, in effect, immune system activity can inhibit mental illness. If, contrary to D, mental illness can depress immune-system activity, the association mentioned does not support the researcher’s conclusion. So D must be assumed |
