今天,我和外公、外婆一起去欧尚大卖场。走过我们的学校,听到知了发疯一样的叫声。暑假前,我怎么没有听到?放假了,知了就都飞进学校里来了?外公笑着说:“越越,阳浦小学知了本来就很多,你没有注意到。”我说:“秋天开学,知了声就没有了。《十万个为什么》书中说,雄蝉的生命只有10天。” Today, my grandmother and my grandfather went to Auchan hypermarket. Walked through our school, heard the same crazy voice. Before the summer vacation, how did I not hear? Holiday, and I knew they were flying into the school. The grandfather laughed and said: “The more you go, the Yangpu Primary School knows a lot and you did not notice it.” “I Says: ”Autumn begins and there is no knowing sound.“ One Hundred and Thousand Why ”said in the book that the life of a male is only 10 days.“ ”
