Emma Cleveland was teaching a class in mathematics at a college. She began to explain to the students how to solve a very difficult problem. She undersood it very well. But somehow, at that moment, she could not explain it. Emma said, "I must be losing it." Emma Cleveland在大学里教数学.她开始向学生们解释如何解决一个难题,她对此理解得非常透彻.但是,在那一刻,不知怎么了,她却解释不出来.Emma说:"我一定解答不出来这道题了." Americans seem to have a lot of concern about losing it. At least that is what you would think from hearing them talk. 美国人似乎对Losing it的问题很关心.至少你会听到他们这么说时,会这么想. ________________________
