The expression "To go down in history" means to become famous and be remembered in the future (like King Henry VIII). To go down in a school subject means to get bad marks or to fail. This boy has gone down in history as he has probably not done very well in his history test.
「To go down in history」解作名留青史，但「to go down in a school subject」就解作那一科考得很差甚至「肥佬」，這個男生「went down in history」恐怕不是像亨利八世般有名（以其有過六段婚姻，還把兩個前妻斬首而聞名於世），而是歷史測驗「凍過水」。■漫畫&說明︰英國文化協會
