What grade was Xu Yuanhuai's debut?

Feiyun Brocade is a kind of plant belonging to the stone lotus of the Crassularia family. Its leaves were of moderate thickness and color, giving people a comfortable feeling. The maintenance was relatively simple. They liked sufficient light, but they could not be exposed to the sun to avoid burning the leaves. They also did not need to control the water too much. They could grow well as long as they maintained ventilation. Watering needed to be controlled well. In spring and autumn, the soil in the pot should be watered after it was dry. When the temperature was high in summer and low in winter, watering should be reduced appropriately. In winter, you should pay attention to keeping warm. The environmental temperature should not be lower than 5 degrees Celsius. The method of reproduction was relatively simple. It could be done by cutting the well-grown stems or leaves and planting them into the medium for cuttage reproduction. The original novel of " The Shadow of Beacon Burning Plum Fragrance " was " The Hitman's Diary of the Pseudo Song Dynasty." The original plot was equally exciting.

The following is a teaching design and reflection on the circumference of a cylinder and a cone: ##1. Teaching Design 1. ** Teaching goal ** - Knowledge and Skill Target - To make students understand the concept of the circumference of the bottom of a cylinder and cone through observation and operation, and master its calculation method (according to the circumference formula of a circle, where r is the radius and d is the diameter). - It could accurately distinguish the difference between the circumference of a cylinder and a cone. - process, method, goal - Through the observation, measurement, and related practical operations of cylindrical and conical models, students 'hands-on ability and spatial imagination were cultivated. - Guide students to explore the calculation of the circumference of the cylinder and cone to improve their logical thinking ability and the ability to solve practical problems. - Emotions, attitudes, values, goals - It allowed students to experience the beauty of geometric figures in the process of mathematics learning and experience the close connection between mathematics and life. - It introduced the history of Pi and stimulated the students 'national pride and passion for learning mathematics. 2. ** Teaching Difficulties ** - teaching focus - Understand the concept of the circumference of the bottom of a cylinder and cone and master its calculation method. - Able to accurately use the circumference formula to solve practical problems related to the cylinder and cone, such as finding the circumference of a known bottom radius or diameter, or finding the radius or diameter of a known circumference. - teaching difficulties - Understand the relationship between the cone's side profile and the circumference of the bottom (the arc length of the cone's side profile is equal to the circumference of the bottom). - To let the students understand the relationship between the length of the cylinder's side expansion and the circumference of the bottom (the length of the cylinder's side expansion is equal to the circumference of the bottom), and to be able to use it flexibly in practical calculations. 3. ** Teaching Method ** - [Intuitative demonstration method: By displaying the physical model of the cylinder and cone, animation demonstration, etc., students can intuitively observe their shape and structure, especially the relationship between the bottom and the side, which is helpful to understand the concept of perimeter.] - Group Cooperation Exploration Method: Arrange students to carry out group activities, such as measuring the diameter and circumference of the bottom of a cylinder and a cone, and discuss the calculation method of the circumference together to cultivate the students 'sense of cooperation and exploration ability. - Question guidance method: Ask a series of targeted questions to guide the students to think, such as "What is the relationship between the length of the cylinder's side expansion and the bottom?" "How is the arc length of the fan-shaped side profile of a cone related to the circumference of the bottom? To encourage students to actively explore knowledge. 4. ** Teaching process ** - lead-in portion - Show the cylindrical and conical objects in your daily life, such as cylindrical cups, cans, conical funnels, Christmas hats, etc., guide the students to observe the shape and characteristics of these objects, and ask the students if they know how to calculate the circumference of their bottom surface, thus leading to the topic of this lesson. - knowledge explanation - Recalling the circumference formula of a circle, C = 2'pi r='pi d', emphasize that' pi 'is a constant (approximately equal to' 3.14'). - For a cylinder, the bottom of the cylinder was two identical circles, and the circumference of the cylinder was calculated using the circumference formula of the circle. At the same time, it was shown that the side of the cylinder was a rectangular shape (in special cases, it was a square). The length of the rectangular shape was equal to the circumference of the bottom circle, and the width was equal to the height of the cylinder. Students could understand it more intuitively through animation demonstration or physical model expansion. - For a cone, the circumference of the bottom was also calculated according to the circumference formula of a circle. Then, through the demonstration of the side view of the cone (fan-shaped), it was explained that the arc length of the fan-shaped arc was equal to the circumference of the bottom of the cone, so that the students could understand this special relationship in the calculation of the circumference of the cone. - group activities - The students were divided into groups, and each group was given a model of a cylinder and a cone, as well as measuring tools (such as a soft ruler). - Students were required to measure the diameter of the bottom of the cylinder and cone and calculate the perimeter of the bottom. - The groups discussed the relationship between the length of the cylindrical side profile and the circumference of the bottom, and the relationship between the fan-shaped arc length of the conical side profile and the circumference of the bottom. Then, each group sent a representative to report. - class exercise - Basic exercise: Give the radius or diameter of the base of a cylinder and cone and have students calculate the perimeter of the base. - For example, if you know the length and height of the cylinder's side profile, find the radius of the cylinder's bottom; if you know the central angle and radius of the cone's side profile, find the perimeter of the cone's bottom. - Class summary - Guide students to review the concept, calculation method, and application of the circumference of the bottom of a cylinder and a cone. - It emphasized the relationship between the circular cylinder's side profile and the bottom circumference, and the relationship between the circular cone's side profile and the bottom circumference. - after-school homework - Arrange some practical homework, such as asking students to measure the diameter of the bottom of a cylindrical or conical object at home and calculate the circumference, or design a cylindrical or conical model according to the given circumference. ##2. Reflection on Teaching 1. ** Success ** - The visual teaching effect was good. Through visual teaching methods such as physical display, animation demonstration, and group measurement activities, the students had a clearer understanding of the shape characteristics of the cylinder and cone as well as the concept of perimeter. Most students could accurately calculate the circumference of the bottom of a cylinder and cone, and could apply the relevant knowledge to simple practical problems. - Teamwork stimulated learning enthusiasm. The development of group activities allowed students to learn from each other and inspire each other through cooperative inquiry, increasing students 'participation and enthusiasm for learning. In the group discussion, students could actively think about the relationship between the side development of the cylinder and cone and the circumference of the bottom, and come to the correct conclusion. - Connecting it with the reality of life to deepen their understanding. In the homework, students were required to measure and calculate cylindrical and conical objects in their lives, so that students could feel the wide application of mathematical knowledge in their lives and further deepen their understanding of knowledge. 2. ** Inadequacies ** - Some students still had difficulty understanding the cone's side profile. Although they had demonstrated and explained it, some students still found it difficult to understand the relationship between the arc length of the circular cone and the circumference of the bottom. It was easy to make mistakes when solving related complicated problems. - The difficulty level of the classroom practice was not clear enough. In the classroom practice session, for students with better foundations, some of the questions were less difficult and did not fully develop their potential. For students with weaker foundations, some of the expansion exercises were too difficult, causing them to be afraid of difficulty. - The timing was not accurate enough. In the group activity segment, because the students were discussing more enthusiastically, they spent more time. As a result, the classroom practice and summary segment were a little rushed, and the students were not allowed to practice and review their knowledge. 3. ** Modification measures ** - In view of the difficulty of the cone side development drawing, more diverse teaching methods were adopted. For example, they could make a conical model that could be disassembled and assembled by the students themselves, so that they could feel the relationship between the arc length of the fan and the circumference of the bottom more intuitively, or they could add some targeted special exercises to let the students deepen their understanding in the practice. - To improve the design of classroom exercises. The practice questions were divided into three levels: basic, improvement, and expansion. They were arranged according to the different learning levels of the students, so that every student could get effective training in the practice. - More precise control of teaching time. Before the group activities, the time limit for the discussion was clearly informed to the students. During the inspection process, the teachers guided the students in the direction of the discussion in time to ensure that each teaching session could be carried out according to the plan to avoid situations where the time was too long or too short. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Autumn Dragon Sword was the sword of Xiao Meng, the leader of the Daoist Heavenly Sect in the series of The Legend of Qin. It was ranked ninth among the top ten famous swords in the Feng Huzi sword manual. This sword contained the power of Taoism and contained the vitality of heaven and earth. It was found by the famous Sword Minister Xue Zhu to match the Clear Sable Sword. It was a peerless divine weapon, and its power was even stronger than the famous sword, Snow Ji. It was dazzling and small, and it was more suitable for girls or handsome men to use. At the same time, it was both a sword and a horsetail whisk.

"Echo" had a deep analysis of human nature in many dimensions: ** 1. Manifestation of human nature in the case ** 1. ** Greed and ugliness ** - In the case of Xia Bingqing's death, the greedy and ugly side of human nature was fully displayed. After Xu Shan Chuan raped Xia Bingqing, in order to get rid of Xia Bingqing's entanglement, he used a series of methods such as bribery and hiring killers to magnify his selfish desires and evil deeds. He had slept with his nephew's fiancée, and his behavior was extremely immoral. This reflected his greedy nature without any moral bottom line. In order to satisfy his own desires, he did not hesitate to trample on others. - Liu Qing hired Yi Chunyang for 100,000 yuan. He knew that there might be a problem, but he still did it. He only had money in his eyes. His disregard for other people's lives reflected the ugliness of human nature. Yi Chunyang had killed Xia Bingqing for 10,000 yuan and cruelly chopped off her hand. This action had exposed the greed and cruelty of human nature towards money. - Wu Wenchao easily sold his love for 500,000 yuan, accepted the commission of both parties, and became the "intermediary" of the complicated relationship in the case. He lost his persistence in love in the face of money, and the greed in human nature made him fall into this big net of interests. 2. ** The Human Choice Behind the Butterfly Effect ** - Starting from Xu Shan Chuan raping Xia Bingqing, it triggered a series of chain reactions. Different people would make different choices for different desires. This was a manifestation of human nature under the influence of interests, emotions, desires, and other factors. Xu Haitao looked for Wu Wenchao to ask Xia Bingqing to leave, and Wu Wenchao looked for Liu Qing to ask Xia Bingqing to migrate. Everyone was considering their own interests. In this process, Xia Bingqing's life became pale and powerless under the balance of other people's interests. This showed that human nature would often ignore the basic rights and interests of others when facing their own interests. ** 2. Humanity in emotional relationships ** 1. ** The conflict between love and trust ** - The relationship between Ran Dongdong and Mu Dafu reflected the complicated human nature of love and trust. Ran Dongdong was an outstanding female criminal police officer with a woman's suspicion and sensitivity. During the investigation, she discovered that her husband had a regular room record and began to suspect that her husband was cheating. As she confronted her husband and went deeper, she found that both of them were at least mentally cheating. Here, love and trust, which were originally thought to be positively related, clashed. Ran Dongdong thought that her love for her husband was love, but after a deeper investigation, she found that it was more trust, and it was difficult to rebuild trust after it collapsed. Her husband's love for her seemed to be based on his control over her human nature, which reflected the complexity and fragility of human nature in emotional relationships. 2. ** Revenge and disloyalty in love ** - Chui Ni as Shen Xiaoying, in order to take revenge on her husband, she had an affair with her own fitness coach, and the daughter beside her was not her husband's at all; Dong Jie as Bei Zhen, who was willing to be Mu Dafu's lover without a name, acting as a third party; Zeng Xiaoling was willing to have an affair with Xu Shanchuan, a married woman, in order to get a promotion. The disloyalty and revenge of these characters in emotional relationships revealed the negative factors of selfishness and vanity in human nature. When their emotions were frustrated or in order to satisfy some of their own needs, they chose to treat emotional relationships in a way that violated morality and ethics. ** 3. The struggle of humanity in the protagonist Ran Dongdong ** 1. ** The conflict between occupation and self-awareness ** - Ran Dongdong regarded investigation as her career. She had the sensitivity and strict logic of a hunter. In the process of solving a case, she asked everything to the end, not only the suspect, but also her husband. Her persistence in the case and her self-exploration reflected her rigorous self-discipline. However, as a woman, there was a conflict between her professional pursuit and her self-awareness. She had to prove herself in the field of criminal investigation dominated by men, but she also had to face her own emotional and family problems as a woman. This conflict reflected the struggle of human nature under different roles and social expectations. 2. ** The exploration of human nature and the exposure of one's own humanity ** - While Ran Dongdong solved the case and explored the humanity of others, he also exposed his own humanity. Her subjective nature in solving cases and her obsession with cleanliness in relationships caused her to bleed when she faced her husband's problems. In the process of exploring the human nature behind the case, she was also constantly examining her own human nature. Her experience reflected that human nature was multi-sided. When she examined others, she would also be examined by others. " The Alliance of Stars: A Symphony of Fate and Power " is equally exciting. Everyone is welcome to click and read it!
