gwd 25-11 逻辑大家帮忙讨论一下

Q11.

which of the following most logically completes the passage?

On the whole, scientists do their most creative work before age forty, a

tendency that has been taken to show that aging carries with it a loss of

creative capacity. An alternative explanation is that by age forty most

scientists have worked in their field for fifteen or more years and that by

then they have exhausted the opportunity for creative work in that field.

Supporting this explanation is the finding that      

A.     the average age of recipients of scientific research grants is signif-

icantly greater than forty.

B.     a disproportionately large number of the scientists who produce

highly creative work beyond age forty entered their field at an

older age than is common.

C.     many scientists temper their own expectations of what they can

achieve in their research work by their belief that their creativity.

will decline as they age.

D.     scientists who are older than forty tend to find more satisfaction in

other activities, such as teaching and mentoring, than they do in

pursuing their own research.

E.      there is a similar diminution of creativity with age in nonscientific

fields, such as poetry and musical composition.

答案是B 实在想不明白。

文中提出两种不同的观点来解释40岁以后科学家的发现就减少了。如果仔细看，第二个观点提出时是以However的感觉提出的，有一定转折，意味着作者可能倾向这个观点。所以，第二个观点之后最有逻辑性的延续应该是进一步证明第二个观点。

第二个观点认为到40岁，大多数人已经在业界做了15年以上了，所以已经把该有的出成果的机会基本上都过了一遍。这个观点的关键之处是从业的时间长短决定出成果的机会，和人的年龄本身关系不大。所以答案B非常明确，那些入行晚的科学家的创造性生命结束的也完。以此来证明从业时间而不是年龄决定科学家的创造性生命的长短。

谢谢指点！

B

文章其实说的是，工作15~20年就没有创造性

B说进的晚，所以创造性工作也出来的晚，当然也就大于一般的40岁，一个普通人工作了15~20年的年龄
