我不记得他的本名——也许谈不上不记得,因为根本就没人清楚告诉过我他叫什么,整个长沟村里的人,都称他“老头子”。一次家访的时候,“老头子”的奶奶说过他的名字,可老人的西北口音特别重,我根本就听不懂到底那是哪几个字,只知道他姓牛——长沟只有两家姓氏,一家姓牛,一家姓张,“老头子”是牛家人。第一次见到他,是在我中考结束远赴长沟参加暑期支教的第二堂课上。我当时分到的支教任务之一是教会学生玩魔方。 I do not remember his real name - maybe it can not be forgotten, because no one told me what he meant. The whole village in Changgou Village called him “Old Man”. When a home visit, “old man ” grandmother said his name, but the elderly are particularly heavy northwest accent, I simply do not understand what it is in the end, only know that his name is cattle - long ditch only Two surnames, a surname cattle, a surname Zhang, “old man ” is a cow family. The first time I met him, I finished my exams and went to Changgou to participate in the second session of summer teaching. One of the tasks I was assigned to at that time was to teach the students to play Rubik’s Cube.
