你眼中的句子可能就是上面这样的，
黑的地方你是看不懂的。
简单地说就是：
Professors treat A as B while (但是）（professors ) portray C as D.
而我们在考场上只能读懂：B=the proper subject of study
尤其是：proper，
我们就能知道教授们对于：the progressive interpretation of history and progressive public policy 的态度是正态度，
由于有while这个转折词我们就能知道，教授们对于C的态度是负态度
我们来比对一下就能知道：
39. The author implies in Paragraph 5 that professors are________.
[A] supportive of free markets（这个属于文章C的内容）
教授不支持C，所以A选项不对，
[B] cautious about intellectual investigation
这里不是在对文章A或者C表态，
而且教授没有表达过谨慎这种态度，所以不选
[C] conservative about public policy（这个属于文中A的内容）
教授对于公共政策的态度是什么文章也没有表达，
教授是支持激进个公共政策的。
[D] biased against classical liberal ideas
教授确实反对经典自由主义的观点！
所以答案选D！
这个思路要是没有明白就看下面的文字版的解析：
Today, professors routinely treat the progressive interpretation of history and progressive public policy as the proper subject of study while portraying conservative or classical liberal ideas—such as free markets and self-reliance—as falling outside the boundaries of routine, and sometimes legitimate, intellectual investigation.
教授们通常认为对于历史激进的解释和激进的公共政策是恰当的研究对象，但是却认为保守主义或者古典自由主义的观点，比如自由市场，自立等，是位于日常（routine）的知识探究范畴之外的，甚至有时是位于合理（legitimate）的知识探究范畴之外的。
所以教授表达的就是对于”保守主义或者古典自由主义的观点“的鄙视！
所以答案选D！
[D] biased against classical liberal ideas
