标题: prep08 CR1 80 [打印本页] 作者: pinkhelicopter 时间: 2011-8-8 10:48 标题: prep08 CR1 80 In many scientific disciplines, scientists generally do not do highly creative work beyond the age of forty, a tendency that has normally been taken to show that aging carries with it a loss of creative capacity. However, by the age of forty most scientists have been working in their chosen field for at least fifteen years, so an alternative explanation is that spending too long in a single field reduces the opportunity for creative thought.
Investigating which of the following would be most useful in choosing between the competing explanations described above?
A. Whether among those scientists who do highly creative work beyond age forty a large proportion entered their field at a considerably later age than is common
B. Whether scientists' choice of research projects tends to be influenced by their own belief that their most creative work will be done relatively early in their career
C. Whether 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
D. Whether funding agencies are more inclined to award research grants to scientists who are veterans in their field than to scientists who are relative newcomers
E. Whether there is significant variation among scientific fields in the average age at which scientists working in those fields are at their most productive 作者: pinkhelicopter 时间: 2011-8-8 10:49
为什么选c 解释不太看得懂作者: pinkhelicopter 时间: 2011-8-8 23:55
错了，答案是A，题目上给的解释是这样的： 说科学家过了40岁创造力就下降了。但是大多数过了40岁的科学家在自己的领域至少工作了15年了，所以这种单一的模式减少了创新思维的产生，问评价？A选项在说是否那些过了40岁但是高创新的科学家进入该领域晚，言下之意，是的话，那就说明文章的假设是对的，因为进入晚的还没到15年，所以还没失去创造力。如果假设是错的，那么说题干就是错误的，即便过了40岁但是还是创造力高，跟年龄没关系。 又看了一遍，还是不太明白作者: hanshipeng 时间: 2011-8-9 03:44
答案就是一方面不能解释而另一方面能解释的。 一方面：年龄大于40，不容易做出成就。 另一方面：进入领域太久，不容易做出成就。 A答案：年龄大于40还能有成就，这个第一个方面解释不了，但是后半句是转入新领域不久。所以另一个方面就解释了。作者: pinkhelicopter 时间: 2011-8-9 18:45
我觉得还是不对 A是说那些40岁以上有成就的人是不是大部分都被认为进入该领域晚。
