[填空题]Questions 47 to 51 are based on the following passage.
That experiences influence subsequent behaviour is evidence of an obvious but nevertheless remarkable activity called remembering. Learning could not occur without the function popularly named memory. Constant practice has such an effect on memory as to lead to skillful performance on the piano, to recitation of a poem, and even to reading and. understanding these words. So-called intelligent behaviour demands memory, remembering being a primary requirement for reasoning. The ability to solve any problem or even to recognize that a problem exists depends on memory. Typically, the decision to cross a street is based on remembering many earlier experiences.

[单项选择]In American high schools today, it’s taken as a given that extracurricular (课外的) activities bring students of different races together. What’s more, it’s on clubs and sports teams that the conditions of Allport’s Contact Theory are actually met—students are working together toward a single goal, rather than competing against each other.
If school districts can widely integrate their sports teams and clubs, then they might see less self-segregation in the hallways and lunchrooms.
It fell to a Duke University scholar, Dr. Charles Clotfelter, to figure out a way to measure how well schools are doing on this front.
Clotfelter could easily look up the racial composition of every school—those numbers are tracked by the National Center for Education Statistics. But the racial makeup of clubs and sports teams wasn’t as easy. How to go about getting a tabulation (列表) of who’s in the drama club, belongs to the engineering society, and runs the school newspapers
