The president of Smith College in Massachusetts said “A women’s college 30 women to choose classes and activities 31 . For example, if a woman student wants to learn math, she will be given the chance. So the percentage of students who like to study math in a women’s college is 32 than that in a college with men and women.” Experts say men students in the United States 33 have enough courage to speak in class. 34 , women students can’t. In a women’s college, women feel free to say 35 they want to. According to a report, women colleges also 36 leadership ability in many fields. At a women’s college, every 37 office is held by women.

Maybe that is why this kind of college is liked by people now. 21. A. make B. elect C. offer D. call 22. A. some B. most C. few D. none 23. A. liked B. accepted C. attracted D. helped 24.
