同学们,首先,我想给大家讲一个故事:有一个男孩,智力比一般孩子差。一天,他站在地图前,呆呆地看着埃及,看着金字塔所在的位置。他父亲走过来说:“你别看了,我保证,你永远也到不了那个地方。”几年后,这个孩子从埃及给他父亲寄来一张照片:他站在埃及的土地上,他的身后就是金字塔。照片的背后写着一行字:生命不能被保证! My classmates, first of all, I want to tell you a story: There is a boy, and his intelligence is worse than the average child. One day, he stood in front of the map, staring at Egypt, looking at the location of the pyramid. His father walked in and said, “Don’t read it, I promise, you will never be able to reach that place.” A few years later, the child sent a photo from Egypt to his father: He was standing on the land of Egypt. He Behind is the pyramid. Behind the photo is a line of words: Life cannot be guaranteed!
