Typing mistakes caused me trouble. Composition (500 words)

Recently, students in our class have always written wrong words, which has caused many jokes and unpleasant things.

Here's the thing. One afternoon after school, Mr. Lei gave us a strange assignment and asked us to write the names of the whole class. In the morning class the next day, Mr. Lei solemnly named himself. "Wang Xiaoming", "Here!" "Li Dongping", "Here!" "Ai Jianhui", the classroom was silent and no one answered. Teacher Lei called "Ai Jianhui" again, but no one answered. Everyone thinks it's strange. Only Yuan Jianhui in our class didn't mourn for him, so the teacher couldn't have mispronounced. Looking at the teacher's serious face, everyone understood at once. The students burst into laughter with a bang. It turned out that in yesterday's homework, many people's names were wrongly written by their classmates. Yuan Jianhui was written as Ai Jianhui, Lan Ya Ping, and Lai Le was written as Lazy Music ... The teacher called the roll according to the names written by his classmates, so no one answered when he called the roll just now, which caused everyone to laugh.

I remember in a Chinese class, Teacher Lan told us a story: In the past, a farmer was accidentally bitten by a snake and did not go to the hospital for treatment in time. I didn't go to the hospital until it was swollen. The doctor diagnosed and said, "Your index finger must be removed, otherwise it will corrode." The farmer was really reluctant to part with it, but there was no other way, so he agreed. When the doctor wrote the prescription, he mistakenly wrote "cutting the index finger" as "cutting the ten fingers". When farmers came out of the operating room, ten fingers were missing, which led to lifelong disability and loss of labor ability, and also caused medical malpractice disputes.

Hey, look, how much damage a typo does! Be sure to form a good habit of writing carefully from an early age, and never write typos!
