Feifei-127

127. Anthropologists assert that cultures advance only when independence replaces dependence---that is, only when imposition by outsiders is replaced by initiative from within. In other words, the natives of a culture are the only ones who can move that culture forward. Non-natives may provide valuable advice, but any imposition of their views threatens independence and thus progress. If one looks at individual schools as separate cultures, therefore, the key to educational progress is obvious:

which one of the following best completes the passage?

A.        individual schools must be independent of outside imposition

B.        some schools require more independence than others, depending on the initiative of their staffs and students

C.        school systems officials must tailor their initiatives for change to each individual school in the system

D.       outsiders must be prevented from participation in schools’ efforts to advance

E.        the more independent a school is, the more educational progress it will make

费费宝典关于此题详解:

答案:A

A可由文中可得到: cultures advance必要条件是 when independence replaces dependence---that is, only when imposition by outsiders is replaced by initiative from within, 而问题问的是: educational progress, 所以根据cultures advance的必要条件可以推出A, Assumption: individual schools as separate cultures

B，C，E无

D错误，因为: Non-natives may provide valuable advice

我的问题是:

1. 对解释中highlight部分不理解, 请大家指点.

2. 答案A没问题. 只是想问一下A是原文信息"Anthropologists assert that cultures advance only when independence replaces dependence---that is, only when imposition by outsiders is replaced by initiative from within."的infer吗?

原文信息可以推出: cultures advance--->independence 或 initiative from within

难道可以推出: culture separate--->dependence 或 outside imposition 吗?

如果可以, 不成了原命题的否命题也成立了吗? 迷惑中...
