請把這句話譯成漢語According the Department of Labor,many colleges raised their fees at twice the rate of inflation from 1980 to 1984 because faculty salary increase in the late 1970's grew much faster than inflation and schools had to raise them to retain faculty members.

據人力部門（勞務部門？）的資料顯示，很多學院在1980到1984年間學費的加幅，都在兩倍通漲的水平以上。原因是學院薪酬在1970年代后期的漲幅是遠高於通漲，故此學院都有需要相應調整學費，以應付及減輕優質教師流失的壓力。
