50.           

Generally scientists enter their field with the goal of doing important new research and accept as their colleagues those with similar motivation.  Therefore, when any scientist wins renown as an expounder of science to general audiences, most other scientists conclude that this popularizer should no longer be regarded as a true colleague.

The explanation offered above for the low esteem in which scientific popularizers are held by research scientists assumes that

(A) serious scientific research is not a solitary activity, but relies on active cooperation among a group of colleagues

(B) research scientists tend not to regard as colleagues those scientists whose renown they envy

(C) a scientist can become a famous popularizer without having completed any important research

(D) research scientists believe that those who are well known as popularizers of science are not motivated to do important new research

(E) no important new research can be accessible to or accurately assessed by those who are not themselves scientists

此题答案我是通过分析文中第一句话得到的,但用LAWYER的取非削弱就不会了.

向大家来请教思路.谢谢

我觉得D取非后就是

research scientist believe that those who are well known as

popularizers of science are motivated to do important new

research.那么就能满足作为合作者的条件。与结论相反

这题不要取非削弱，有一个GAP

条件：因为有相似的动机，科学家彼此视为同党；

结论：有科学家A搞科普，其他科学家不视之为同党。

“有相似的动机”和“科学家A搞科普”需要搭桥。

假设：“科学家A搞科普”不被视为“有相似的动机”。

这题确实用取非削弱真绕不出来了.呵呵.

但我自己认为最难的就是找这类题目里面的GAP.这是不是说明还是没有理清罗辑顺序? 我一般看完题就是理一句话出来,但从来看不出来里面的GAP,求赐教.

别这么客气，探讨而已

GAP一般是：条件：B推出C

           结论：A推出C

           搭桥或拆桥：A推出B；A推不出B
