這是與教育有關的研究
Some university colleagues of mine discovered a persistently inconsistent hiccup in their masses of research data on students' school performance..
...a hiccup of excellence that could be explained by the fact that the teachers in a particular school gave a damn.
如果把hiccup翻成打嗝好像很怪, 難道是他們在研究學生的不尋常打嗝與老師的關係嗎?
