对我们小学生来说,如果不进厨房,日常生活中几乎接触不到火,但是每天我们又离不开火。火曾经让人类的祖先敬畏,并改变了人类的生活。你有没有想过,如果人类不会使用火,那会是怎样一种情景?每到新年,漫天的焰火是否激起你对火的另一种思考? For our primary students, if we do not go to the kitchen, there is almost no fire in our daily life, but we can not leave a fire every day. Fire has awe the human ancestors, and changed the human life. Have you ever wondered what it would be like if humans did not use fire? And every New Year, is the fireworks in the sky provoking your other thinking about fire?
