1. Physicist Ampère was walking on the street one evening, and suddenly he had a problem in mind, so he walked to the "blackboard" in front of him, took out the chalk head from his pocket, and performed the calculation on the "blackboard". However, the "blackboard" suddenly moved places, and Ampere's calculus was not finished, and he unconsciously followed behind the "blackboard" to calculate. The "blackboard" went faster and faster, and Ampere felt that he could not catch up, and then he saw that the people in the street were laughing at him, and he realized that the moving "blackboard" turned out to be the back of a black carriage.

3. There are thousands of Zhongsu in the book, ** house in the book, and Yan Ruyu in the book. Life has its own sorrows and joys, life has its own separation and integration, and life has its own sweetness and pain. There are ups and downs in the book, joys and sorrows in the book, joys and sorrows in the book.
The book has its own colorful dreams of teenagers, the simple shadow of middle-aged people in the book, and the red of the sunset of the elderly in the book.
4. Lu Yao said: "Each of our lives is a world, but we need to work hard for it to make it live in vain." "Whether it is ordinary or dazzling, we should combine life in front of and behind the scenes to make our world full of wonderful.
We are willing to be unheard of at this moment, to accompany our relatives and embrace friendship. We can also bloom at this moment, write pride with the tip of the pen, shout out our dreams, and make the world pay attention with our actions. This kind of life is not impetuous, not boring, both fulfilling and beautiful.
May we be able to aspire to it.

I have found that some people still smoke in public places such as: schools, restaurants, parks, amusement parks, etc., and I hate those who smoke very much.
Tobacco smoke contains at least three dangerous chemicals: tar, nicotine, and carbon monoxide. Tar is a mixture of several substances that concentrate into a viscous substance in the lungs.
Nicotine is an addictive drug that is absorbed by the lungs and mainly acts on the nervous system. Carbon monoxide reduces the ability of red blood cells to transport oxygen throughout the body. Smoke from smoke is a carcinogen, which means that it can cause cancer in the tissues it comes into contact with, so it is possible for smokers to develop cancer anywhere in their breath.
Nicotine can also increase the heartbeat and blood pressure, and tobacco smoke, possibly due to carbon monoxide, seems to promote atherogenesis, which is a cause of many heart diseases, and people who smoke a lot of cigarettes have a much greater chance of dying from a heart attack than non-smokers. A person who smokes 15 to 20 cigarettes a day is 14 times more likely to develop lung cancer and is 14 times more likely to die from oral or throat cancer than a non-smoker. They are 4 times more likely to die from esophageal cancer than non-smokers; The chance of dying from bladder cancer is twice as great; The chances of dying from heart disease are also twice as high. Cigarette smoking is a major cause of chronic bronchitis and emphysema, and the lungs itself increase the risk of pneumonia and heart disease, and smoking also increases the risk of high blood pressure.
Those smokers who like to smoke, quickly put down the cigarette butts in their hands, protect their bodies together, and contribute to the motherland and society!
During the War of Resistance Against Japanese Aggression, a nationally famous anti-Japanese hero appeared in Moyuan County, Hebei Province, and his name was Wang Erxiao. Wang Erxiao was only seven years old when he died, and when the Japanese devils swept a ravine, in order to cover thousands of fellow villagers and cadres, he risked his own life and led the enemy into the ambush circle of the Eighth Route Army. The angry Japanese devil picked Wang Erxiao on the tip of the gun and fell to his death on the top of the big rock. >>>More

I was also looking for it, and I found my brother.
You didn't know which one.
Heartfelt words to parents.
