The characters in the book all have normal intelligence. The detailed descriptions slowly spread out a magnificent foreign world for the readers. The collision between the fourth natural disaster and the residents of the foreign world; the unknown conspiracy of the demon king; the foreshadowing of the grass snake gray line are all amazing. Not bad. 7."Low-Dimensional Revolution": It's especially good. This author's works were all of good quality. The plot is very novel, and the setting is also the type that I really like... Five star recommendation ~ 8."Human Killing Intent, Heaven and Earth Repeatedly": A good book that uses "Qi" to win. First, there was true "chivalrous spirit". Nowadays, most of the books were read by egoists who were extremely exquisite. They paid attention to the softness, wretchedness, femininity, hypocrisy, and ruthlessness of their bodies. Even if they were twisted into a fried dough twist, they would seize the opportunity to make a fortune, be promoted, steal the country, cultivate immortality, and seek development. It had been many years since they had seen such a high-spirited man's book. Some of the twists and turns were slightly abrupt and simple, but it was already difficult to cover up the heroic spirit that filled the paper. It was simple and vigorous, valued righteousness and despised life, and was chivalrous and spirited. It made people's spirits rise! 9."Earth Survival Guide": Read Little Shepherd Boy's old book. The content is vivid, the writing is humorous, and there are all kinds of imaginative stories. It belongs to one of the wooden bucket universes. There are all kinds of interactions. Old readers will even have a surprise egg! 10."Player's Supreme Justice":"Player's Supreme Justice" was a novel with a very interesting setting. The author used nightmares as an explanation for the dungeon. This setting was very exquisite. The power system in the story was also very exciting, especially the setting of the curse that made the entire power system balanced and interesting. In addition, the book also contained a grand worldview that people yearned for. It filled people with anticipation. Although the author seemed to be immersed in the reasoning of the plot, it did not affect the overall plot. Instead, it made the story more interesting. The style of this novel was light, combining elements such as the fourth Calamity Style, the Esoteric Sect simulator, the Summoning Player Style, and the Amber Style. The entire world view was complete. There were both funny and brain-burning elements. The overt and underhanded writing was very exciting. Although the author had dug many holes, these holes were filled in bit by bit, so the readers could not skip through them. They had to slowly appreciate them. "Player's Supreme Justice" was a fantasy dungeon puzzle light novel. It told the story of the protagonist, Annan, who traveled to the fantasy world as a game planner and became the heir of the archduke who was being hunted. He summoned the players from Earth to the other world and led them to crack the dungeon and explore the fantasy world. This world view was magnificent and grand, with precise and rigorous settings. It was also innovative, and the power system was also very novel and interesting. The creation of the puzzle-solving instance was also very ingenious. It perfectly combined the player with the game world, making people very interested. In short, this book was a fantasy game from the west. The story structure was similar to that of a Super Mechanic, but it had its own characteristics. Each character in the book had their own unique characteristics and intelligence. Especially in the setting of the Nightmare Instance Dungeon, it perfectly combined the players with the game world, which was very interesting. I strongly recommend it for everyone to read! "American TV Series World Adventure":"American TV Series World Adventure" was a book that traveled through the main storyline of the male lead of an American TV series. The plot was compact and fascinating. The protagonist had traveled to the world of the Song of Ice and Fire, displaying his wisdom and courage. As the famous young eagle of the Empire, he displayed his elegant demeanor and the temperament of a young leader under the sun. However, he also showed his tenacity and determination in the fog. He traveled through various planes and awakened thousands of corpses, which was unacceptable to the human world. The plot of this book was so tight that it was hard to put it down. At the same time, it also triggered the readers to think about real society and history. Overall, this was a good book worth reading. "Blackstone Code": Similar to a certain empire that was banned in the previous book. No female lead, profit flow, no bottom line. 13."Ten Thousand Enemies of the Warring States Period" [The review is too strict. The single owner really has no choice but to try to modify it back and forth.] [Everyone can leave a message on the book list or contact the fan group of the novel.] "The American Sage":"The American Sage" is a refreshing novel. The author brings a new reading experience to the readers with his unique creativity and stiff writing style. The story was about an international student who met the background of the immortal sect in the United States. It combined immortal cultivation with modern society and showed a world full of imagination. The author added a touch of interest to the novel by describing how the protagonist used modern technology to help him cultivate. The setting of the revival of reiki in the story, as well as the confrontation between the ancient gods and the Native Americans, made the novel more tense and exciting. In short, this book was a work of fodder, and the subsequent developments were worth looking forward to. 15:"Cyber Hero":"Cyber Hero" is an amazing cyberpunk martial arts novel. The author skillfully combined two seemingly unrelated elements to create an amazing world. The story was set in the 1930s. A group of like-minded young people worked hard to change the world. However, in a garbage dump, the first ancestor of the Cyber Martial Arts, Xiang Shan, was lost. "The Infinite Style of the Meta-Universe":"The Infinite Style of the Meta-Universe" was a novel with a new perspective. The author had put in a lot of effort into introducing the plot. Although the long narrative description affected the reading experience, overall, the book still needed to be more readable. The opening was very stunning. The protagonist's IQ fluctuated between high and low, surprising people. At the same time, it also made people praise the excitement of the dungeon. The author's description of the characters was excellent, allowing the readers to feel the excitement of the movie when reading the text. The whole story spanned a long time, and the characters were constantly growing. This continuous attraction made people unable to stop. Overall,'The Infinite Universe' was a very good novel and worth reading. Mystery Makes Me Strong: 90/100 Looking at the ratings, the author's grasp of the plot was comparable to the writing style of "Endless Joy in a Small World" during the same plot development period. However, the author was more realistic and had a better grasp of the main character. He loved it! As for why there was no introduction to the plot, I personally felt that it was only after I read it that I felt like ohh was like this. Sigh, I felt a myriad of emotions. 18:"Out of the Cage": The nucle-powered battleship is an old sci-fi author in Qidian's future. It is a key target of the River Crab God! Currently, only this "Out of the Cage" and the previous "Return" could still be seen at the starting point! I personally like the author's books very much! From "Butterfly in the Plane,""The Battle of the Well," and "Infinite Heavy Resistance," he had basically read all of them. These books were all sci-fi masterpieces with a huge brain hole, a huge structure, a deep accumulation of knowledge, and a top-notch logic! The author's books were more inclined towards the infinite style, but they only told their own stories in the infinite style. The worlds that the main characters entered were mostly original or semi-original worlds. The settings were very interesting, and they were not limited to the plot, but focused on the overall deduction based on the world view. The main characters were all teenagers with strange and upright views. They all had the experience of studying abroad on Earth, so they climbed the technology tree to solve all their problems! The book was mixed with a large number of private goods, but it did not make people feel annoyed. Instead, it made people feel very touched! It was worth a look! Plot summary: A 21st-century youth was influenced by a high-dimensional existence and was reborn hundreds of years later. At that time, it was already after the fourth World No War. The direction of technological development had changed, and he could already explore and discover the secondary plane. The main world of Earth was also full of contradictions. The protagonist was chosen as the explorer of the secondary plane, and thus began to explore and develop the multi-dimensional plane, breaking out of the cage of Earth. 19:"Dream God": Comfortable, the author has a new book, hurry up and add it 20."The Emperor's Angel of Death": This is the 41st millennium of the Milky Way Human Empire. This is the story of that era. Mankind had forgotten the power of science and technology, and had forgotten too much to ever regain them. Mankind had also forgotten the promise of progress and understanding, because in this cruel and dark future, there was only war. There was no peace among the stars, only endless slaughter and slaughter, as well as the wild laughter of the hungry gods. Soshyan Alexei, a combat cultivator of the Astral Knights Legion, was also the only survivor of the World Engine Battle. He shouldered the responsibility of rebuilding the legion, carrying secrets that could shake the galaxy, and headed into the unknown…

Guanyin gave birth to a Buddha statue, jade ware
There were many forms of Guanyin's child-giving Buddha statue jade. Among them, the jade Guanyin child-giving statue was an old cultural relic collected by the Qing Palace. It was 17.2cm high and 6cm wide at the bottom. The jade material of the jade Guanyin child-giving statue of the Ming Dynasty was bluish-white and slightly yellow. The whole statue was carved with a standing Guanyin and a baby in both hands. This was produced under the background of the obvious secularized tendency of jade articles in the Ming Dynasty. At that time, jade products were more about daily life in terms of shape and decoration. This kind of "Guanyin Sending a Child" jade carving was a display with Buddhist colors. In addition, there were also natural Burmese A-grade jade child-sending Guanyin pendants and other Guanyin child-sending Buddha statues sold in the market. For example, Yuyun Jewelry Store on the south bank of Gaoyao District, Zhaoqing City, Guangdong Province, sold jade child-sending Guanyin pendants wholesale. The price varied according to the number of purchases. The material was Burmese jade, the type of farming was bean seeds, etc. There were also after-sales services such as one-for-three compensation for fakes, payment for reinspection, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Code for children's photography studio layout in residential buildings
The following are some specifications for the layout of a children's photography studio in a residential building: ** 1. Spatial planning ** 1. area - The smallest space of about 20 square meters could be used to build a live studio. Through the combination of several real scenic spots, more than 10 theme shots could be completed. 2. partition - It could be set up in different areas such as the baby room, living room, bedroom, bathroom, bathroom, study, lounge, etc., focusing on a comfortable home environment. ** 2. Scene design ** 1. Material selection - Pay attention to realism and environmental protection. For example, in the renovation of children's studios, the paint should be professional children's paint. Because the content of harmful heavy metals was extremely low, all of them were prepared with water. The content of volatile organic compounds was close to zero, and the colors available were rich and easy to scrub. - Children's furniture is recommended to be composed of modules. It is necessary to consider whether it is environmental friendly and avoid excessive levels of formalin and heavy metals. Even solid wood furniture needs to be paid attention to because the use of glue may contain formalin. At the same time, attention should be paid to avoid the overlapping effect of harmful substances, especially in the studio of a small residential building. 2. security - From the selection of materials to the corners of the tables and chairs, safety must be fully considered and rounded to prevent children from being injured during the filming and playing process. ** 3. Staffing ** - There should be staff with a clear division of labor, such as specialized live photographers, hygiene and item maintenance personnel, guides and assistants familiar with live operations, etc. ** 4. Lighting ** - According to the characteristics of the real scene, the lighting effect was designed reasonably. In order to improve the replication of the work, the lamps could be fixed to ensure the stability of the shooting level. ** 5. Other aspects ** 1. ground processing - If the floor was not tiled, cork flooring could be used to prevent young children from walking unsteadily and falling. 2. electricity safety - Power outlets and switches should be covered with safety covers. Protective devices should be added to electrical appliances to prevent the baby from directly touching the light bulbs and heater. Do not use floor lamps, floor fans, etc. to prevent the baby from tripping and getting an electric shock. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Hello, you were caught selling cultural relics and sent to the detention center.
If he was caught in the detention center for selling cultural relics, it meant that he might be suspected of selling cultural relics. The crime of reselling cultural relics referred to the act of reselling cultural relics prohibited by the state for profit. The circumstances were serious. As for the punishment of the crime, if it is the reselling of general cultural relics, unless the transaction amount is more than 50,000 yuan, it will constitute the crime of reselling cultural relics; If the reselling of cultural relics above Class II, reselling more than 5 pieces of Class III cultural relics or the transaction amount is more than 250,000 yuan, etc. are considered "especially serious circumstances", they will face more severe punishment, with imprisonment of not less than five years but not more than ten years and a fine. If a unit commits this crime, the unit shall be fined, and the person in charge and other directly responsible personnel shall be punished. However, if it was a first offense, actively returning or assisting in the recovery of cultural relics, did not cause any damage to the cultural relics, and did show signs of repentance, it could be considered a minor crime and may not be sued or exempted from criminal punishment. In addition, there may be some problems with the management and medical conditions of the detention center. In recent years, there have been many cases of deaths due to illness in the detention center, but the judicial system will gradually improve the relevant conditions of the detention center to protect the basic rights and interests of the prisoners. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are the beautiful and minimalist photography techniques?
Here are some of the most beautiful and minimalist photography techniques: - * * In terms of background processing ** - * * Simple background **: Simple background is the foundation of minimalist photography. The background could be a single-colored wall, wooden board, or a single-colored background paper or cloth. Whether it was a single subject or multiple subjects (but the number of subjects should be appropriate), the background should be simple. - * * Color matching of background and main body ** - * * Single Color Match **: This is the simplest and less error-prone method. It is suitable for people who are not good at color matching. It can create a harmonious and unified atmosphere. For example, a light brown background with a light brown puppet, a light blue background cloth with a light blue coil, a white background cloth with milk, etc. - * * Neutral and warm colors **: It is more common in daily life. Neutral colors mainly refer to black and white and gray series with different shades of black and white. Warm colors include yellow, yellow-orange, etc. In the minimalist color scheme, white and various warm colors were the most common and not easy to make mistakes, such as orange and white cloth, corn and white tabletop. - * * Picture composition ** - * * Picture blank **: Similar to the blank space in ancient Chinese literati landscape paintings, the blank space in minimalist photography can give people space to imagine, rather than being empty and meaningless. - * * Clear theme **: The theme is clear and the main body may be small due to the large amount of blank space. When composing, you can use the central composition and three-point composition to emphasize the existence of the main body, so that people can see the main body at a glance. When shooting people, they paid more attention to the body posture, movements, and the relationship between the person and the environment rather than the details of the expression. When shooting still life and scenery, they pursued the artistic conception of the existence of the object and the contrast between the object and the surrounding environment rather than a certain detail. - [Remove Messy Elements: This is one of the distinctive features of minimalist photography. By removing the messy elements in the picture, the picture is made simple and clean.] - * * Color usage ** - * * Color simplicity **: In order to highlight the minimalist effect, there is no need for too many colors on the screen. You can refer to formal wear. Generally, there are no more than three colors. - * * In terms of shooting skills ** - * * Shooting Techniques **: Such as pushing the camera, pulling the camera, shaking the camera, moving the camera, following the camera, raising the camera, lowering the camera, and surrounding the camera. This can help the photographer capture the minimalist image better. - [Choose a suitable subject: The sky, windows, and the order of buildings are all good minimalist photography subjects.] For example, when shooting the sky, other simple elements could be incorporated to increase the fun; when shooting the window, light and shadow could be used to pursue perfect symmetries; when shooting the order of the building, it could show the orderly and repeated elements of the building. - * * Use light and shadow effects **: Light and shadow can add a dramatic effect to the picture. For example, when shooting windows, light and shadow can break the original pattern of the picture and give the photo more artistic sense. - * * Using post-production software **: Post-production software is also a part of photography creation. It can be used to strengthen and enhance photos to achieve a minimalist style. For example, changing the color tone, choosing the black and white shooting mode, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Teaching plan and reflection on the small skills of chemical organic problems
** I. Chemistry and organic problems tips lesson plan ** #(I) Teaching objectives 1. ** Knowledge and Skill Target ** - Students can master the types, reaction conditions, and reaction mechanisms of common organic chemical reactions. - Learn to predict the possible reactions of organic matter based on its structural characteristics. - Proficient in writing organic chemistry equations, including the correct writing of reaction conditions. 2. ** Course, Method, and Target ** - Through the induction and summary of the types of organic reactions, the students 'logical thinking ability and induction ability were cultivated. - Using examples to improve students 'ability to analyze and solve organic chemistry problems. 3. ** Emotions, attitudes, values, goals ** - Cultivate the students 'interest in learning organic chemistry and eliminate the fear of learning organic chemistry. #(II) Difficulties in Teaching 1. ** Teaching Focus ** - Reaction mechanisms of common organic reaction types (such as electropathic substitution, nuclopathic substitution, electropathic addition, nuclopathic addition, elimination reaction, free radical reaction, etc.). - Memory and application of reaction conditions in organic chemistry equations. - The relationship between the structure and properties of organic matter. 2. ** Teaching Difficulties ** - Understand the microscopic processes such as electron transfer and intermediate formation in organic reaction mechanisms. - Writing complex organic reaction equations, especially when it involved multi-step reactions. #(3) Teaching Method Teaching method, induction method, case analysis method, group discussion method. #(IV) Teaching process 1. ** import (5 minutes)** - Show some common organic substances in daily life, such as alcohol, plastic, gasoline, etc. Ask the students about their understanding of the nature of these organic substances. Guide the students to think about the variety and complexity of organic substances, thus leading to the theme of this lesson-- 2. ** Explanation of organic reaction types and mechanisms (20 minutes)** - electrophilic substitution reaction - Using the substitution reaction of the aromatic ring as an example, he explained how an electrophile reagent (such as a chloride-positive ion) attacked the electron rich aromatic ring, forming a positively charged intermediate (the carbon positive ion on the aromatic ring), and then leaving a neutron to complete the reaction. The effect of the electron cloud density of the aromatic ring on the reaction was emphasized. - nucleophilic substitution reaction - They introduced the reactions of Sn1 and Sn2 respectively. For the Sn1 reaction, using the example of tert-Butyl Bromine in water, the reaction rate was only related to the concentration of the reagent. The reagent first dissociated into a carbenium ion and a negatively charged leaving group, and then the carbenium ion combined with the nuclophile. For the Sn2 reaction, using the reaction of methybromides and NaOx as an example, it was explained that a nuclophile would attack an electron deficient central atom with a pair of lone pair electrons, forming a transition state. During the reaction, the configuration would flip, and the reaction rate was related to the concentration of the reagent and the nuclophile. - electrophilic addition reaction - Using the addition reaction of ethene and helium as an example, the electrophile (bromination) attacked the saturated bond (carbon-carbon double bond), forming a positively charged intermediate (bromination), and then combined with the negative ion to complete the reaction. - nucleophilic addition reaction - Taking the addition reaction of an aldo or a keto with hydrogen cyanic acid as an example, it was shown that the nuclophile (cyan negative ion) attacked the positively charged carbonyl-carbon atom to form a negatively charged intermediate, and then completed the reaction through steps such as proton-transfer. - elimination reaction - E1 and E2 reactions were described separately. The E1 reaction was based on the dehydration of tert-Butyl alcohol under acidic conditions to produce Isobuten. The reaction rate was only related to the concentration of the reagent. The reaction rate was only related to the concentration of the reagent. The E2 reaction was based on the reaction of the alcoholic solution of bromic ether and lithium ether. The reaction rate was related to the concentration of the reagent and the base. - free radical reaction - The reaction process of the free radical reaction was explained by taking the reaction of the free radical produced by the homolytic cleavage of the bond, and then the chain initiation, chain growth, and chain termination as an example. 3. ** Relationship between the structure and properties of organic matter (10 minutes)** - Demonstrate the structures of different types of organic substances, such as alkyls, alkynes, alkyns, alcohol, aldo, keto, and carbolic acid. - The characteristics of the functional groups were analyzed, such as the unsaturation of the carbon-carbon double bond and the affinity of the hydrogen radical. The students were guided to understand the decisive role of functional groups in the properties of organic compounds. - For example, the difference in properties of the same functional group in different structures, such as the difference in the acidic properties of alcoholic and alcoholic functional groups. 4. ** Writing Skills for the Formula of the organic chemistry (10 minutes)** - It emphasized the importance of reaction conditions, such as temperature, catalyst, and the influence of the reaction. - Using some typical organic reactions as examples, such as the fermentation reaction and the dehydration reaction of a class of aromatic compounds, he explained the correct writing of the reagents and products when writing the equation, as well as the annotation of reaction conditions. - Remind the students to pay attention to the balance in the organic reaction equation, especially when it involves the conservation of elements and charge. 5. ** Group discussion and case analysis (10 minutes)** - Some examples of organic chemistry problems were given, such as the identification of organic compounds and the design of organic synthesis routes. - The students were divided into small groups for discussion. Students were required to use the types of organic reactions, reaction mechanisms, and equation writing skills to solve the problem. - Each group would send representatives to share the results of the discussion, and the teachers would comment and summarize. 6. ** Summing up (5 minutes)** - Review the types of organic reactions, reaction mechanisms, the relationship between the structure and properties of organic substances, and the writing skills of equations. - He emphasized the importance of mastering these small skills to solve organic chemistry problems. #(5) Teaching Resources Multi-media class, blackboard, chalk. #2. Teaching Reflection 1. ** Success ** - Through the combination of various teaching methods, such as lecture method, case analysis method, and group discussion method, students could learn organic chemistry tips more intuitively and deeply. The students showed high enthusiasm in group discussions and were able to use what they had learned to solve practical problems, which showed that this teaching method could help improve the students 'ability to analyze and solve problems. - When explaining the types and mechanisms of organic reactions, students would be able to better understand the abstract reaction process by relying on specific reaction examples, especially for reaction mechanisms that were difficult to understand such as electropathic substitution and nuclopathic substitution. Students would be able to grasp the nature of the reaction through examples. - The emphasis on the relationship between the structure and properties of organic substances and the writing skills of organic chemistry equations would help students establish a systematic knowledge system when learning organic chemistry, laying a good foundation for subsequent learning and solving problems. 2. ** Inadequacies ** - During the teaching process, it was found that some students still had difficulty in understanding the microscopic processes such as electron transfer and intermediate formation in organic reaction mechanisms. Although examples and animations were used, these concepts were relatively abstract, so more teaching methods such as model demonstration were needed to help students understand. - In the group discussion session, although most groups could actively participate, there were still some groups that relied on individual members, resulting in some students not fully participating in the discussion. In the future, he needed to pay more attention to the division of labor and cooperation among the members of the group to ensure that every student could play a role in the group discussion. - As for the explanation of the writing skills of organic chemistry equations, although the students could master the basic writing methods in class, they found that some students still had problems such as the wrong reaction conditions and the wrong equation balancing when they encountered complex organic reactions. In the future, he needed to add more practice and feedback links to correct students 'mistakes in time. 3. ** Modification measures ** - In order to solve the problem of students 'difficulty in understanding the mechanism of organic reactions, they could create some simple molecular models and let the students operate them personally to intuitively feel the process of electron transfer and intermediate formation. At the same time, they could look for more examples related to real life to materialize abstract concepts and improve students 'understanding. - In order to improve the low participation of individual students in group discussions, they could pay more attention to the differences in students 'abilities and personalities when grouping, and reasonably match the group members. Before the discussion, the tasks and responsibilities of each member, such as recorder, reporter, discussion organizer, etc., were clearly defined. At the same time, the inspection and guidance during the discussion process were strengthened, and every student was encouraged to speak actively. - In order to improve the students 'ability to write organic chemistry equations, appropriate targeted exercises were arranged after class, and they were corrected and fed back in time. In class, they could set up quizzes on equation writing to find problems and correct them in time. At the same time, it could guide students to establish a book of mistakes, sort out and analyze the equations that often made mistakes, summarize the reasons for the mistakes, and improve the accuracy of their writing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
