小兔白白有一个坏毛病:学习时很不认真。为这个毛病,兔妈妈不知说过它多少次,可它就是改不了。它曾为此闹过不少笑话,最后吃了大亏。一天,兔妈妈教小兔白白看图识字时,指着一张画着牛的画片说:“这是牛伯伯,是草食动物,它为防御敌害侵袭,头上长着两只角。” The rabbit has a bad problem in vain: study is very serious. For this problem, rabbit mother do not know how many times it, but it can not be changed. It used to make a lot of jokes, and finally suffered a big loss. One day, when a rabbit's mother taught a pupil to read pictures in plain pictures, she pointed at a picture of a cow and said: “This is Uncle Niu, a herbivore. It has two horns on its head against enemy predators. ”
