Look at the definition of "ancient poetry" first. Ancient poetry is the general name of China's ancient poetry, which refers to 1840 China's poems before the Opium War. From the perspective of meter, ancient poetry can be divided into ancient poetry and modern poetry.
Two. ? It was during the second industrial revolution that mankind began to learn to use electricity. China first started to use electricity as energy in 186 1 year. So there is no story about saving electricity.
Electricity is an energy source driven by electric energy. 19 The invention and application of electric power in the 1970s set off the second climax of industrialization. It has become one of the three major scientific and technological revolutions in the world since the18th century in human history, and technology has changed people's lives since then.
The second industrial revolution was marked by the widespread use of electricity. As early as 183 1, the British scientist Faraday discovered the electromagnetic induction phenomenon and put forward the theoretical basis of the generator. Based on this discovery, scientists have conducted in-depth exploration and research on electricity since the 1960s and 1970s, and a series of electrical inventions have emerged. 1866 generator made by Siemens, Germany. /kloc-in the 1970s, practical generators came out. During this period, a motor was invented that can convert electrical energy into mechanical energy. Electricity began to be used to drive machines and became a new energy source to supplement and replace steam power. Subsequently, electrical products such as electric lights, trams, electric drills and electric welding sprang up like mushrooms after rain. However, in order to apply electricity to production, we must also solve the problem of long-distance transmission. 1882, Frenchman Depreux discovered the method of long-distance power transmission, and American scientist Edison established the first coal-fired power station in the United States, connecting power lines into a network. Electricity is an excellent and cheap new energy. Its wide application has promoted the rapid development of a series of emerging industries such as power industry and electrical appliance manufacturing. Human history has entered the "electrical age" from "age of steam". China first started to use electricity as energy in 186 1 year. 186 1 year later, Wuhan, the British consular residence, was the first, with electric lights. Hankou electric power company, founded by British businessmen, uses the special thermal power generation in British concession. Soon, the concessions of Russia, France, Germany and Japan successively supplied electricity.
Shanghai is one of the earliest cities in China to produce and use lighting appliances. In the eighth year of Guangxu in Qing Dynasty (1882), the first power plant invested by British businessmen was built in Shanghai, and began to supply lighting electricity, which created the history of using electric lights in Shanghai.
1886 (the 12th year of Guangxu), Xiyuan and Sanhai, built large-scale buildings and palaces. During the construction of the palace, modern western scientific and technological products were introduced into the Three Seas, and electric lights were installed in the Ilan Hall.
3. China officially started to save water in 199 1. The Water Law of People's Republic of China (PRC) was revised in 2002. So there are no ancient poems about water saving.
Starting from 199 1, China municipal government will take the second week of May every year as the publicity week of urban water conservation. Further improve the awareness of the whole society to care for, cherish and protect water, and promote the development, utilization, protection and management of water resources.
Starting from 1994, China municipal government changed the time of "China Water Week" to March 22nd to 28th every year. On March 22, 20001year, the "national water-saving symbol" appeared, which indicated that China had a special symbol to publicize water-saving and mark water-saving products.
Article 8 of People's Republic of China (PRC) Water Law (revised in 2002): The state strictly saves water, vigorously promotes water-saving measures, popularizes new water-saving technologies and processes, develops water-saving industries, agriculture and services, and builds a water-saving society. People's governments at all levels shall take measures to strengthen the management of water conservation, establish a system for the development and popularization of water conservation technologies, and cultivate and develop water conservation industries. All units and individuals have the obligation to save water.
Fortunately, there are some ancient poems about saving rice. After all, China existed as an agricultural country most of the time.
Two Poems for Farmers by Don Li Shen
one
In spring, as long as you sow a seed, you can harvest a lot of food in autumn. There is no waste of heaven and earth, and the toiling peasants are still starving to death.
Secondly,
At noon in summer, the sun is very hot, farmers are still working, and beads are dripping into the soil. Who would have thought that our bowl of rice and grain are full of the blood and sweat of farmers?
Millet: commonly known as millet (scientific name: Setaria viridis)
Italian), known as "Ji" in China. The grain made of chaff is named because it is very small, with a diameter of about 2 mm. Originated in the Yellow River valley in northern China, it was the main grain crop in ancient China, so Xia and Shang Dynasties belonged to "millet culture". Millet is drought-tolerant, with many varieties, commonly known as "colorful millet", including white, red, yellow, black, orange, purple millet and sticky millet. The earliest wine in China was also made from millet. Millet is suitable for growing in arid areas without irrigation. Its stems and leaves are hard and can be used as feed. Generally only cows can digest it. Xiaomi is commonly known as Xiaomi in northern China. Western languages generally refer to small grains such as millet, millet and royal millet, which are generally not distinguished by non-agricultural experts. For example, English is called "Xiaomi". Now people also use millet for breakfast and porridge.
