I recently read a book about mathematics: The King of Mathematics. As soon as I got this book, the lovely cover attracted me deeply, and I finished reading it with a happy mood.

Among the Kings of Mathematics, the most impressive one is Adventures in an Embarrassed Country, which mainly tells that Xiaoming is a careless king. When doing math problems, I made a lot of jokes because of carelessness, so that the teacher made a lot of red crosses on the papers handed down. It turns out that Xiao Ming wrote the answer on the paper: an apple weighs 200 kilograms, and the area of a stamp is 1 square meter. It seems that Xiao Ming is really careless enough. On this day, Xiao Ming suddenly saw a man the size of a matchstick on the table. Before he could speak, the villain took Xiaoming's hand and went to the amusement park by train. It is difficult to get on the train. Why does the train go so slowly? Xiao Ming felt very strange and asked the driver. The driver said, "didn't you write it?" I drive at your speed. " "Yes, yes, it's all your carelessness, otherwise I wouldn't be so short." Finally, the train arrived and Xiao Ming couldn't wait to get out of the carriage. "Oh, dear!" "A 200 kg apple hit Xiao Ming hard on the head. Xiao Ming was about to get angry, but then he thought, isn't this his fault? Well, next, he met his small classroom, huge stamps ... Xiaoming secretly vowed that he must get rid of his careless bad habits in the future.

I didn't think it was a big deal to be careless. I'll do it myself anyway. Just pay attention next time. But after reading Xiao Ming's story, I feel that carelessness is really harmful and has caused many consequences.

It's terrible. If the rocket designer is a little careless, the rocket will not go to heaven; If the satellite data has a little error, it will not be able to orbit the earth normally; If the doctor leaves the surgical instruments in the patient's body, it will bring pain to the patient and do harm to the body ... In order for us to study better, gain more knowledge and become useful talents in the future, without making mistakes or delaying things. Everyone should overcome carelessness and get rid of the bad habit of carelessness. Whether studying or working, we should be serious, serious, serious, careful and careful. Let's all study carefully.
