“With the increase in the number of such advertisements, however, each advertiser within a certain group is competing with others in the same group for the reader’s attention”，故选项D正确。 Psychologists take opposing views of how external rewards, from warm praise to old cash, affect motivation and creativity. Behaviorists, who study the relation between actions and, argue that rewards can improve performance at work and school. Some other researchers who study various aspects of mental life, maintain those rewards often destroy creativity by encouraging dependence on approval and gifts from others.

The latter view has gained many supporters, especially among educators. But the careful use of small monetary rewards sparks in grade-school children suggesting that properly presented inducements indeed aid inventiveness, according to a study in the June Journal Personality and Social Psychology.

“If they know they're working for a reward and can focus on a relatively challenging task, they show the most creativity,” says Robert Esenberger of the University of Delaware in Newark. “But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards.”

A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Esenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore falling grades.

In earlier grades, the use of so-called token economics, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims.

答案与解析：

1. D

心理学家认为外界的奖励对学生会有不同的影响。事实辨析题。根据文章第一句话“Psychologists take opposing views of how external re wards, from warm praise to old cash, affect motivation and creativity”可知，心理学家的分歧在于来自外界的奖励对学生的积极性和创造性究竟有什么影响，故选项D正确.

2. C

许多教育家对外界的奖励持怀疑态度。

文章第二段第一句话提到，后一种观点得到了许多教育工作者的支持，从第一段中可知，后一种观点是：奖励会促使学生对别人的赞许和馈赠产生依赖心理，因此奖励会破坏创造精神。由此可知，他们对奖励的正面作用持怀疑态度。故选项C正确。

3. A

根据文中的研究结果表明，教育家通过给予学生应得的奖励来提高他们的积极性和创造性。文章第三段指出，给予学生恰当的奖励，可使他们发挥更大的创造性，但如果对糟糕的表现也给予奖励，或让学生对奖励有太多的期许，反而会扼杀创造性。故选项A正确。

4. B

从文中可以得知，一些重点大学试图加强等级标准，因为他们相信惩罚比奖励更有效。事实辨析题。从文中第四段可知，许多大学之所以严格考试的评分标准，是因为“A teacher ... who hands out high grades for ordinary achievement ends up with uninspired students”。选项B 与此意相同。

5. C
