老师在给同学们批改作业的时候,经常用√表示正确,用×表示错误。可是你知道吗,这个√和×是由两个英语单词演化而来的。√与right有关,因为right的中文意思是“正确的”;×与fault有关,因为fault的中文意思是“错误的”。那 When the teacher corrects homework assignments for the classmates, they often use √ to indicate correctness and x to indicate mistakes. But did you know that this √ and × were evolved from two English words. √ √ right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right right. that
