A few days ago, some adults around me were still childlike and played games with the children in the kindergarten. Adults have funny language, funny looks and clumsy actions. One of the children said, "it turns out that adults can also be very interesting." these children have not borne the weight of their studies. They are innocent, happy, interesting and enviable; Adults rarely have fun, but in exchange for children's incomprehension, it is touching. Living in the present, with fierce social competition, not only adults are difficult to have fun, but also growing students seem to have the same trouble. A few years ago, I read a report that there was a question in the Chinese test paper of the independent enrollment examination of a University: make up a 150 word joke with the four words "Peking University, Tsinghua University, college entrance examination and No. 1 scholar". One examinee said, "I have the heart to lift the table when I see this topic." I think the reason why the examinee said this is probably because of the lack of fun in life. But who is to blame? In the sea of questions, students surrounded by heavy pressure can hardly have the mood to brew fun. Fun can reconcile life, reduce stress and eliminate negative energy. Adults should be good at brewing fun and take good care of children's fun. At home, parents should cultivate children's fun - they shouldn't kill their fun at will. In school, teachers may as well create more scenes, innovate forms, cultivate students' hobbies, and plant the seeds of fun in their hearts. (outlook new era)
