[填空题]The New Math on Campus
Sexual Imbalance in Colleges
After midnight on a rainy night last week in Chapel Hill, N.C., a large group of sorority (女学生联谊会) women at the University of North Carolina squeezed into a basement bar. Bathed in a colorful glow, they splashed beer from pitchers, traded jokes and shouted lyrics to a Taylor Swift heartache anthem thundering overhead. As a night out, it had everything--except guys.

Women have represented about 57 percent of enrollments at American colleges since at least 2000, according to a recent report by the American Council on Education. Researchers there cite several reasons: women tend to have higher grades; men tend to drop out in disproportionate numbers; and female enrollment leads further among older students, low-income students, and black students.
