编辑同志:我的儿子两岁九个月,能认识一些汉字、英文字母,认识一些基本的几何图形。他早已学会正确地从1数到10,但最近他故意数成1、2、5、7、8,并把早已熟知的英文单词故意发成错误的音。当别人纠正他的错误时,他总说别人不对,请问这是什么原因,应该怎样教育?北京王兆印 Editor’s Comrade: My son, two years and nine months old, knows some Chinese characters, English letters, and some basic geometric figures. He had learned to correctly count from one to ten, but recently he deliberately counted into 1, 2, 5, 7, and 8, and deliberately made the already familiar English word into the wrong tone. When others correct his mistakes, he always said that others wrong, may I ask what is the reason, what should be the education? Beijing Wang Zhaoyin
