In the ancient legend of China, Kirin, dragon and phoenix, and tortoise were combined into four spirits, and they were the king of the hairy beast. Kirin is a godsend of ordinary people. There is a folk saying that "Kirin sent the son", saying that Confucius was sent by Kirin; Kirin is dotted with stars, so it is one of the most famous auspicious animals. Kirin contains benevolence and righteousness. In the ancient culture of China, there are many legends about the rise and fall of emperors and Kirin. Kirin, like Phoenix, is hermaphrodite and Qi is male. The forest is female, and the moose's body, oxtail, fish scales and feet are even-hoofed (but there is also the saying that Kirin has five toes). She has a horn on her head and meat on it. Kirin, as a mascot, was often used in the political affairs of ancient dynasties in China. Historically, Emperor Wu of the Han Dynasty built the Qilin Pavilion in Weiyang Palace, painted heroic images as a reward, and showed the world his love for talents. Kirin is also widely used in official uniforms. The boudoir emblem of Yipin Guan in Qing Dynasty was decorated with Kirin, which shows that its position is second only to that of dragon. In the Qing Dynasty, only the royalty were qualified to wear the dragon symbol. The emperors included Huanglong and Zilong, and the prince, elder brother, Baylor and Beizi were all dragon designs, implying that they were rich and outstanding in martial arts. 6? 1 ? 6? 1 ? 6? 1 ? 6? 1 ? 6? 1 ? 6? 1, 2 nd floor, more than 3 stars: superior intelligence, 4 in Yunlong; Yu Daoshu is amazing. 5 broadsword; His ancestor is Guan Yu.

(5) The word "unlucky" is a Zhejiang dialect, which originated in the late Ming Dynasty. "Unlucky" never appeared in special sentences, and its appearance was related to the imperial examination system and folk customs at that time. At the end of the Ming Dynasty, the imperial examination system of "stereotyped writing for selecting scholars" was implemented. To be an official, a scholar must pass the imperial examination. Due to the great limitations of the imperial examination, the talents of intellectuals have been seriously affected, and the phenomenon of graft in the examination room is serious, so it is difficult for ordinary scholars to gain fame. For good luck, candidates usually put up a flagpole at home before the exam. At that time, people called this flagpole "lintel". If you pass the exam, the flagpole will remain upright. If you fail, you will have to remove the flagpole. People call it "bad luck" to pull the flagpole. Later, this word was more and more used to describe unsatisfactory things in spoken and written language. Today we write "bad luck" as "mildew" or "eyebrow", but we don't write the original "bad luck", which is also true, but when we use it, we should remember that the word "bad luck" evolved from "bad luck" (6) China's calligraphy is an ancient art of writing Chinese characters.

Zhang's painting is round, so it is wrong and fake. Winter vacation homework's mathematics answer three. Geometry and reasoning. 1. Connect AC, because AD=4 and CD=3, so it is obtained from Pythagorean theorem: AC=5, and because AB = 13 = 169, BC+AC = 12+5 = 65438. 6? 1 ? 6? 1 ? 6? 1 ? 6? 1 ? 6? 1 ? 6? 1 fifth floor = (12× 5)/2-(3× 4)/2 = 30-6 = 24.2.ab, AC3. Because AB=AC, ∠ ABC = ∠ C. Because BC=BD, ∠C=∠BDC=∠ABC. Because AD=DE=BE, ∠ A = ∠ AED = 2. 3 ∠ EDB) = 22.5 ∠A=∠AED=2∠EDB。 So ∠ A = 45.4. (1)∫DE is the center line of △ABC. ∠BCF =∠deb = 90∴△cfe?△EDB(SAS)。 ∴ EF = DB。 AD = DB。 ∴ EF = AD。 ∵ Quadrilateral ADEF is a trapezoid. ∴ ∴∠DMA=∠CMB∵M is the midpoint of∴ cm = dm. ∴△CMB≌△DMA(SAS)∴ trapezoid ABCD is an isosceles trapezoid. (3)∵E is the midpoint of BC, and ∴∴ trapezoid ABCD is an isosceles trapezoid. (4) If the extension line of intersection D is at E, then ∠ BDE = 90. If D at f ∫ trapezoid ABCD is isosceles trapezoid, then DE ∫ AC = BD. And AD. AC = DE = BD ∴△ BDE is an isosceles right triangle. Then df =1/2be =1/2 (BC+ce) =1/2 (BC+ad) =1/2 (m+n). = 1/4 (m+n) Therefore, (m+n) = 4s trapezoidal ABCD. (5) In the isosceles trapezoid ABCD, AB=CD ∠ABC=∠DCB BC is the public side. ∴△ABC≌△DCB(SAS).∴AC=BD AD is male * * * side ∴△ Abd △ DCA (SSS) ∴∠ ABO = ∠ DCO ∠ AOB = ∠. From ef =1/2ab =1/2cd (ef is the midline of △AOB) ∴EF=DG=CG(G is the midpoint of CD) ∵E is the midpoint of AO. ∴DE is the middle vertical line of AO. ∞△DEC = 90。 ∴EF=DG=EG CF is also the middle vertical line of BO. ∴∠ DFC = 90 ∴ FG = CG = EF ∴△ EFG where EF=EG=GF. △ EFG is an equilateral triangle. Winter vacation homework geographical answer 1, C 2, A3, South; Pacific Ocean; Indian Ocean; Warm and humid. Monsoon region; 5.( 1) Summer; (2) the southeast coast; Northwest inland; (3) Flood 6-8 is temporarily omitted. The query operations 1 and (1) can remember the location of the provinces and regions through the main geographical things, such as the upper, middle and lower reaches of the Yangtze River and Yellow River, the provinces and regions on both sides of Taihang Mountain (Shandong in the east and Shanxi in the west), the provinces and regions on both sides of Daba Mountain (Sichuan and Chongqing in the south and Shaanxi in the north) and the provinces and regions around Nanling Mountain (Hunan and Jiangxi in the north and Guangdong and Guangdong in the south) As follows: Guangdong, Guangxi, Henan, Hebei, Shandong, Shanxi) Heijiliao, Xiajin, Jingguan (Heilongjiang, Jilin, Liaoning, Tianjin, Beijing), Qinghai-Tibet, Xing 'an League, Mengshan (Qinghai, Tibet, Xinjiang, Gansu, Inner Mongolia, Shaanxi), Yunnan, Guizhou, Sichuan and Chongqing. In addition, China can be generally divided into east, middle and west regions, and then the provinces in these three regions will be remembered. (4) According to the memory of important cities. For example, Wuhan is a grand event in Hubei Province and a regional central city in Central China. The important ports in the middle reaches of the Yangtze River can be associated with Hubei Province being located in the middle of China, Hubei Province being located in the middle reaches of the Yangtze River (the upper reaches of Yichang River), and Sanya being located at the southernmost tip of China, with four seasons like summer. It can be considered that Hainan, where it is located, is also located at the southernmost tip of China. There are many other examples. 2.K304 is an express passenger train, starting from Lianyungang, going west to Xuzhou via Longhai Line, going from Xuzhou to Fuyang in Anhui via Suifu Line, going from Fuyang to Nanchang in Jiangxi via Beijing-Kowloon Line, going from Nanchang to Zhuzhou in Hunan via Zhejiang-Jiangxi Line, and going from Zhuzhou to Guangzhou via Beijing-Guangzhou Line.
