13题解析和今天的句子

昨晚的基础测评课中13题的句子是这样的：
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, self-reliance and a distrust of central planning as falling outside the boundaries of routine, and sometimes legitimate, intellectual investigation.
切分和简化过后是这样的：
1）Professors treat（认为） A as（是） B.
while
2) Professors portrait（认为） C as（是） D
1句和2句之间的关系是转折关系；
B=the proper subject of study （正面评价）
所以可以知道教授对于A是正面评价；
那么教授对于C那就是负面评价了啊；
想明白了吧！?
今天的句子：
It’s an interactive feature that lets visitors key in job criteria such as location, title, and salary, then E-mails them when a matching position is posted in the database.
