92. Baking for winter holidays is a tradition that may have a sound medical basis. In midwinter, when days are short, many people suffer from a specific type of seasonal depression caused by lack of sunlight. Carbohydrates, both sugars and starches, boost the brain’s levels of serotonin, a neurotransmitter that improves the mood. In this respect, carbohydrates act on the brain in the same way as some antidepressants. Thus, eating holiday cookies may provide an effective form of self-prescribed medication.
Which one of the following can be properly inferred from the passage?
(A) Seasonal depression is one of the most easily treated forms of depression. (B) Lack of sunlight lowers the level of serotonin in the brain. (C) People are more likely to be depressed in midwinter than at other times of the year. (D) Some antidepressants act by changing the brain’s level of serotonin. (E) Raising the level of neurotransmitters in the brain effectively relieves depression. 答案是D。 我的问题是为什么B不对?feifei logic explaination上说B是“没有提到的无关信息”。 可是不是要架桥吗?把逻辑之间的gap连结起来? 原文:冬天由于天短,lack of sunlight,所以人们容易患抑郁症。而吃碳水化合物可以提高作为神经传导素的血清素的含量,而血清素能improves the mood.所以碳水化合物可以扮演抗抑郁药。 所以吃假日曲奇是有效的自我疗法。 我的理解是要架桥:冬天缺少阳光降低了血清素,所以冬假要多吃曲奇(碳水化合物)提高血清素以改善情绪。 所以我认为B和D都对,但是答案是D。呜呜呜~~~
B中的逻辑关系推不出来 文中给出the brain’s levels of serotonin上升,导致 mood变好;lack of sunlight导致seasonal depression,也就是mood变坏。但得不出the brain’s levels of serotonin和lack of sunlight的因果关系。 这是归纳题i,infer,只能用原文信息进行融合,不能搭桥。 D选项能利用原文信息整合出来的,但不是搭桥搭出来的。
