Enjoy, but she regards fame and fortune as dirt. She gave prizes to France in scientific research and war, and gave those medals as toys to her 6-year-old daughter. 7.

(3) Fill in the blanks according to the content of the text and put the correct phrases in brackets: (The new term "radiation" in science textbooks (the new unit of measurement of physics "Curie" (article)) The laws of science) (an eternal milestone in the history of science) These four "changes" describe Madame Curie's life and immortal achievements. Practice writing. Example 1: In this humble laboratory, there is a big pot. Sitting next to the pot is a beautiful and dignified Madame Curie. She has been stirring the industrial waste residue in the pot, and tiny sweat drips from her forehead. There is white smoke floating above the pot. Madame Curie smiled at the contents of the pot and imagined the beautiful radium, just like a loving mother watching a sleeping baby. This work has been going on for quite a long time, but Madame Curie did not waver in her determination, but worked hard as always. Exodus 2: The Curies worked day and night in an abandoned shack and forgot to eat or sleep. In summer, Madame Curie's cabin is like an oven, and in winter, it is freezing cold. Madame Curie stirred dozens of kilograms of waste residue in the pot with iron bars, worked for several hours, even dozens of hours, and perhaps only extracted millions or tens of millions of radium. She left a little burn marks on her face, clothes and hands. Sweat kept flowing on her forehead, her eyes were bloodshot, and her wrinkles were full of her vicissitudes and hardships, but she became a radium mother. Exodus 3: In the center of the laboratory, there is a pot full of smelly slag, and the air is filled with a strong smell. The so-called laboratory is an abandoned laboratory.

Broken shed. Marie Curie took the spoon, held the handle with both hands and slowly stirred the slag in the pot. Her face, skirt and hands left traces of acid and alkali burns. She wiped the sweat from her forehead with her arm and went on working. Her face showed obvious fatigue ... but it was in this harsh environment that Madame Curie discovered the natural radioactive element radium.

If we want to set our goals and move on, we can't hesitate any longer. This is the attitude of perseverance. -Zou Taofen VII. (1) Cross out calculations and accounting corrections (2) "Star" refers to the stacked prime theory written by Hua; "Dust" refers to a calculation error in the book. He's quite right. This teacher is really a talent! (4) China and Chen Jingrun are good at finding talents; Dare to put forward your own opinions. About 200 years ago, a German mathematician named Goldbach proposed that' any even number can represent the sum of two prime numbers', which is called 1+ 1 for short. He never proved it in his life, so he wrote to Euler, a mathematician in St. Petersburg, Russia, and asked him to help prove the problem. After receiving the letter, Euler began to calculate. He tried to prove it to the death. Later, Goldbach passed away with a lifetime of regret, but left this mathematical problem behind. For more than 200 years, Goldbach's conjecture has attracted many mathematicians, thus becoming a big unsolved mystery in the field of mathematics. "For an interesting example, mathematics is the queen of natural science, and Goldbach conjecture is the jewel in the queen's crown!

Six years is as short as a day, but I can't forget every advantage of you. If I were a boat, you would be a sail to guide the direction. Although humble, it keeps me safe. Class one, my example: A: I think Xiao Yu's laughter in Unforgettable Laughter is very vivid. Related sentences: "Gege", this is Xiao Yu's laughter ... which made everyone laugh. Second, warm my heart (1): The students all put down their textbooks and looked up at me with sympathetic eyes. (2) write your own words of comfort. You will always be in my heart: write your own words and write your own characteristics. I deeply feel that the road of life is full of accidents and inevitability, but sometimes you can't succeed without a little encouragement and support. The author also opened the door to literature because of the teacher's guidance. The certificate (1) is eye-catching: the image is obvious, and it is easy to see the glory: glory. Can't wait: it's too urgent to wait. (2) The height here refers to frivolity and pride.

Milestones on the road to growth: the encouragement and support of teachers again and again has become a milestone in my life. I remember when I was in the first grade, half a semester passed, and the exam was coming soon. I was very nervous.

Zhang! I have been comforting myself, don't be nervous, this paper is very simple, you will do well! Although I comforted myself again and again, I still ... Teacher Shen came up to me and said to me gently, "Never mind, relax, believe I can do it!" "To tell you the truth, I am really touched. The old teacher is so kind to me! I started the exam. We were so nervous just now. I calmed down and began to do my test paper. I finished it as quickly as possible. I feel very good. I will definitely get 100 in the exam. I checked it two or three times and handed it in. But when the test paper was delivered to me, I was surprised. I clearly checked and did everything. Why ... I can't help crying? You can't always be discouraged in this exam! You are right! " I wiped my tears and said, "Teacher, you are right. I will report you back and forth with excellent results in the next exam! " "
