The history composition is 800 words 1 mirror, which is your old friend. After brushing my teeth and washing my face every morning, I always habitually go to the mirror, comb my hair, straighten my clothes and tie a red scarf. However, do you know the "resume" of your old friend? Ha, the mirror does have a very interesting history! The earliest mirror was naturally the water surface. China has had such an idiom since ancient times: "The level is like a mirror". In ancient times, people often lay by the river or pond, facing the water and taking a look at their faces. However, such a mirror "wrinkles a pool of spring water" with the wind, and the water waves are sparkling, and nothing can be seen clearly.
Soon, people invented bronze mirrors. The bronze mirrors in ancient China are very famous, which is estimated to be 1800 years old. Not only widely used in China, but also sold to Japan, North Korea and other countries. Li Shimin, Emperor Taizong of Tang Dynasty, famously said: Take copper as a mirror to dress straight, the ancient as a mirror to watch the rise and fall, and people as a mirror to know the gains and losses. Here, "taking copper as a mirror" refers to a bronze mirror. In Egypt, there were bronze mirrors a long time ago. In addition, Europeans made "aluminum mirrors" and Russians made "steel mirrors". But the bronze mirror is too dull, the silver mirror is too expensive and the steel mirror is too easy to rust. The mirrors that people use now are bright, cheap and rustless glass mirrors. The world's first glass mirror was born in Venice, the "glass kingdom". It is achieved by plating a layer of mercury on the glass.
Venice's mirror caused a sensation in Europe and became a very fashionable thing. European princes, nobles and wealthy dignitaries rushed to buy mirrors. When French Queen Marie de Medicis got married, the Venetian King gave her a small glass mirror as a gift. It was a very precious gift at that time, with a value as high as 1.5 million francs! The method of making mirrors is confidential in Venice. They made such a law that anyone who divulges the secret of making glass mirrors to foreigners will be executed immediately. Later, the French ambassador to Venice suddenly received a secret letter from Paris, telling him to try his best to buy several Venetian mirror technicians as soon as possible and smuggle them to France. The French ambassador tried his best to fulfill his mission. 1666, the first French mirror factory appeared in Normandy, France.
But it's too much trouble to make a mercury mirror. It will take a whole month. Besides, mercury is poisonous and the mirror is not very bright. More than a hundred years ago, scientist Libby Xi invented a silver-plated glass mirror-this is the mirror you use now. Mirrors, from the water surface, to bronze mirrors, silver mirrors, steel mirrors, and then to mercury-plated glass mirrors and silver-plated glass mirrors, is this the peak and perfection? Don't! Recently, scientists are experimenting with an aluminized glass mirror. Such a mirror will be cheaper, more durable and brighter than a silver-plated mirror. In addition, people also use gold, aluminum alloy and other metals to make yellow, rose, blue and green color mirrors.
Science and technology are constantly developing, and the history of mirrors is also writing a new page.
Historical topic composition 800 words 2 historical wind chimes, ups and downs in the ear, men and women recite the timbre of history ... "Be a hero when you are born, and be a ghost when you die." You Liu Bangge are shameless and kick down the ladder. Fortunately, your uncles were kind enough to let you die. Hongmen banquet, I sword dance, I didn't stretch your head. Besides, I am Xiang Yu, born as a flying dragon, and my sword refers to mountains and rivers. Today, I let you go home with Liu Bang, making you a "big man" and creating a big man for 400 years. I, Xiang Yu, went out of Jiangdong and led the troops to win the world, but now I am planted in your hands. I have no face to say goodbye to my elders in Jiangdong. I just want the blood of Wujiang River and see that you will benefit the world.
The Wujiang River is rolling, and the river with overlord's blood has already settled, chanting "Born as a hero, died as a ghost", making Li Qingzhao "miss Xiang Yu so far and refuse to cross Jiangdong". On the banks of Wujiang River, the history of despotism and desolation. "With copper as a mirror, you can be well dressed; Taking the past as a mirror can only replace it; Taking people as a mirror, you can understand the gains and losses. " Look at that robe, the golden armor on the battlefield, and the sound of "fifty strings beyond the Great Wall". I, Li Shimin, inherited my father's footsteps and became a military commander of Zhenguan Wenzhi. I hate Yuanji's completion, but he didn't listen to me and made Xuanwu Gate bloody. It is a pity for me that my brothers and sisters are broken and my father and son are broken. I love Ling Xuan Wei Zhi best, and I would rather die than remonstrate with him. If I am forced, I will be destroyed in a snap of my fingers, but I will be taken to North Korea forever.
Hundreds of years later, Chang 'an City is still well known by people, playing the famous saying of the sage, "Water can carry a boat, but it can also overturn it". China's history is the history of Tang Taizong's martial arts, harmony and music. "Although the country is divided, the mountains and rivers remain forever, and the vegetation turns green in spring". As a lonely old man, what can I do? Is it "fighting for fame before death" on the battlefield, or "seeing Nanshan leisurely" in seclusion? When Du Fu saw the officials arresting people in the stone trench, he could only "cry". Seeing the destruction of the capital of Chang 'an, people can only express sadly that "although the country is broken, the mountains and rivers will last forever". I used to say that Xuanzong of the Tang Dynasty was prosperous in the new century, but now the Anshi Rebellion can only be settled in Chengdu. It's a pity that I Du Fu didn't do my best for my country all my life. Looking back on Qu Yuan, an ancient sage, whose soul broke the Miluo River, I can say that "both of them are unhappy-forever and ever". So what, not to mention "it was a long time before I met her, but it has been longer since we broke up". Just look at the Miluo River and you will know the rise and fall of the Tang Dynasty in Chu.
As long as she turns her head and smiles, a hundred spells will be cast. I spent half my life in Li Longji, but I was depressed for the rest of my life. When I started a prosperous new century, the world praised me as "a success before and after my death", but when I owned Yang Yuhuan, I was cast aside as "a pity". This is my contradiction. What is wrong with me? Yuhuan "smiles on the world of mortals", who is not tempted? I have my own love. What's the matter? However, the result of love is indeed a tragic Anshi rebellion. Even so, people still make fun of me, "the meaning of drunkenness is not in wine, but in mountains and rivers." In other words, Yang Yuhuan is indeed, but she is no better than others. Isn't it the beauty that made Gou Jian's "Three Thousand Yue Family Can Swallow Wu"? General Yangmen, why don't you all lead the way?
Listen to it! This is the voice of history. There are patriotic sounds, lofty sentiments, brilliant sounds, court complaints, war sounds in musical instruments ... Time can wear away the surface of historical wind chimes, but it cannot change its timbre. Even after a thousand years, I am still filled with indignation and emotion. The wind chimes of history, rolling in my ear, murmuring the timbre of history. ...
