问题     William Shakespeare described old age as "second childishness" — sans teeth, sans eyes, sans taste. In the case of taste he might, musically speaking, have been even more perceptive than he realized. A paper in Neurology by Giovanni Frisoni and his colleagues at the National Centre for Research and Care of Alzheimer’s Disease in Brescia, Italy, shows that one form of senile dementia can affect musical desires in ways that suggest a regression, if not to infancy, then at least to a patient’s teens.
    Frontotemporal dementia is caused, as its name suggests, by damage to the front and sides of the brain. These regions are concerned with speech, and with such "higher" functions as abstract thinking and judgment. Frontotemporal damage therefore produces different symptoms from the loss of memory associated with Alzheimer’s disease, a more familiar dementia that affects the hippocampus and amygdala in the middle of the brain. Frontotemporal dementia is also rarer than Alzheimer’s. In the past five years the centre in Brescia has treated some 1,500 Alzheimer’s patients; it has seen only 46 with frontotemporal dementia.
    Two of those patients interested Dr. Frisoni. One was a 68-year-old lawyer, the other a 73-year-old housewife. Both had undamaged memories, but displayed the sorts of defect associated with frontotemporal dementia — a diagnosis that was confirmed by brain scanning.
    About two years after he was first diagnosed, the lawyer, once a classical music lover who referred to pop music as "mere noise", started listening to the Italian pop band "883". As his command of language and his emotional attachments to friends and family deteriorated, he continued to listen to the band at full volume for many hours a day. The housewife had not even had the lawyer’s love of classical music, having never enjoyed music of any sort in the past. But about a year after her diagnosis she became very interested in the songs that her 11-year-old granddaughter was listening to.
    This kind of change in musical taste was not seen in any of the Alzheimer’s patients, and thus appears to be specific to those with frontotemporal dementia. And other studies have remarked on how frontotemporal dementia patients sometimes gain new talents. Five sufferers who developed artistic abilities are known. And in another lapse of musical taste, one woman with the disease suddenly started composing and singing country and western songs.
    Dr. Frisoni speculates that the illness is causing people to develop a new attitude towards novel experiences. Previous studies of novelty-seeking behavior suggest that it is managed by the brain’s right frontal lobe. A predominance of the right over the left frontal lobe, caused by damage to the latter, might thus lead to a quest for new experience. Alternatively, the damage may have affected some specific neural circuit that is needed to appreciate certain kinds of music. Whether that is a gain or a loss is a different matter. As Dr. Frisoni puts it in his article, De Gustibus Non Disputandum Est. Or, in plainer words, there is no accounting for taste.
From the passage, it can be inferred that

选项 A、the damage of the left frontal lobe may affect some specific neural circuit.
B、the lawyer patient has the left frontal lobe damaged.
C、the damage of the left frontal lobe decreased the appreciation of certain kinds of music.
D、every patient has the same taste.

答案B

解析 先看四个选项,[A]“左半脑体受损影响一些特殊神经电路”,文章最后一段虽有提到,却讲到了两种可能。所以,[A]的说法是不全面的。[B]“那位律师病人的左前脑体受损了”,律师对音乐的喜好发生了变化,根据文章最后一段医生的推测可知,这位律师病人的左前脑体受损了;[C]“左半脑体受损能减少对音乐的喜好”,文中只提到会影响对音乐的喜好,至于是增加还是减少则不一定;[D]“每个病人有同样的品味”,从文章最后一句可以看出,每个人品味是不同的。故本题选[B]。
