Please help me write the mind map for the second unit of mathematics in the second volume of the first year of junior high school

The light phenomenon mind map was as follows: ``` | | V | | E | | H F | | | | G | | C D C | ``` These are the three basic functions of light: reflection, refraction, and interference. Next was the phenomenon of light refraction: ``` | | V | | E | | H F | | | | G | | C D C | ``` This was the new light produced by the refraction of light. The direction and length of these light rays would change when observed from different angles. Next was the phenomenon of light reflection: ``` | | V | | E | | H F | | | | G | | C D C | ``` This is the reflection of light on a flat mirror or other reflective device. The direction and angle of the reflected light remain the same, but the path of the light has changed. Next was the interference phenomenon: ``` | | V | | E | | H F | | | | G | | C D C | ``` This was an interference phenomenon caused by the collision of two or more beams of light. In the interference, the paths of light would intertwine with each other to form interference fringes. The above are the three basic functions of light and the phenomenon of light interference.

The Wolf in the first half of the second grade or The Wolf in the last half of the second grade

Writing a novel required a lot of knowledge and skills, including writing techniques, storylines, character creation, worldview setting, and so on. Before you start writing, it is recommended to try to conceive the plot and character, and determine the theme and style of the novel. In the process of writing, one had to pay attention to maintaining the cohesiveness and logic of the story to avoid contradictions and logical loopholes. In addition, you must pay attention to the use of writing style and language to make the novel read smoothly and naturally attractive. Writing is a process that requires constant practice and improvement. I hope you can persist in writing and constantly improve your level.

Mind maps are visual tools used to organize and display information to help us better understand concepts and information related to memory. The following is a simple fifth grade mind map: 1. Decide on the topic: In this case, the topic could be "Mathematics". 2. List the knowledge points related to the subject, such as the basic concepts of mathematics, formulas, operators, equations, scores, decimals, proportions, sets, etc. 3. classify the knowledge points: classify each knowledge point according to its importance and difficulty. For example, you can classify scores and decimals according to their difficulty or put them on different branches. 4. Draw branches: Draw some related sub-topics or concepts on each knowledge point. These sub-topics or concepts can be further divided into smaller branches. For example, on the topic of "fraction", you could draw branches such as "fraction","percent sign","decimal point", and so on. 5. Add keywords and comments: Adding keywords and comments to the branch will help you better understand and remember the relevant concepts and information. 6. Perfect Mind Map: Add more branches and details to the Mind Map as needed. The following is a simple example of a fifth grade mind map: ``` Title: Mathematics - Basic Concepts of Mathematics - formula - operator - equation - grade - decimals - percentage - gather The practical application of mathematics - geometry - algebraic method - Adding and Subtracting Fraction and Decimals - Adding and Subtracting Percentiles and Decimals - The application of sets ``` I hope this example will help you better understand and use Mind Maps.

Lin Feng had a different temperament from other children since he was young. He didn't like playing hide-and-seek with other children, nor did he like skipping rope or drawing with other children. He preferred reading, especially science fiction. Every time he got a book, he would excitedly run over and finish reading it. As he grew older, Lin Feng's interests became wider and wider. He learned to play the guitar, sing, and even participated in the school's art performance. He always stood at the forefront and sang to express his love for the world and his longing for the future. Lin Feng's change was even more obvious in middle school. He began to like learning programming and often sat in front of the computer to study various software. His grades were getting better and better, and he became the top student in the class. In the last year of junior high school, Lin Feng decided to participate in the county's sci-fi competition. He spent a lot of time and energy writing a story about space exploration. In the competition, he won the first prize and became the best sci-fi author in the county. Since then, Lin Feng's career had been advancing rapidly. His works were adopted by various media outlets and received recognition and appreciation from many readers. He had become a well-respected person and gained a lot of friends and fans. However, Lin Feng's childhood was still the most precious memory in his heart. He remembered those nights when he sat alone in front of the window and those times he spent with his parents. He knew that even if time passed, those memories would remain in his heart.

Loving Mother was a modern novel written by Lao She and published in 1939. The following is the original text of the novel: She was not my mother, but she was my loving mother. She was already in her seventies, and her body was very weak. She often fell sick. The house she lived in was small and cramped. She was the only one in it. She had no son, daughter, or anyone else. Her life was very difficult. She could only eat a little food and drink a little water every day. But she kept living because she knew that if she died, her sons and daughters would have a hard time. I've been to her house before and saw that it was crowded and the environment was very bad. But every time I think of her motherly love, I feel very warm. She was very good to me and always cared about my studies and life. She often cooks delicious food for me and watches movies and tells stories with me. Although her life is very short, the love she gave me will continue. I hope that she can live a long and healthy life and stay by my side. I will always miss her and be grateful for her motherly love.

As a fan of online literature, I won't recommend specific books, but I can tell you some types and topics that might be suitable for middle school students. First of all, for junior high school students, reading some suspense, reasoning, science fiction and other types of novels might be more suitable. These types of books usually had fascinating plots and deep thoughts. For example, The Complete Sherlock Holmes, The Three-Body Problem, The Galaxy Empire, and so on. Secondly, he could also read some classic literary works such as Dream of the Red Chamber, Journey to the West, and Water Margins. These works are all classics of Chinese literature, with profound thoughts and cultural implications, which are of great help to improve the language and literary appreciation ability. In addition, you can also read some modern literature works such as "One Hundred Years of Solitude","1984","The Kite Runner" and so on. These works reflect different eras and cultures, allowing students to have a deeper understanding of human civilization and social development. Finally, he could also read some popular science books such as " A brief history of time,"" The past of Earth,"" A cosmic tour," etc. These books could help students understand the universe, Earth, science, and other fields to improve their scientific literacy. In short, reading was a very good way of learning. It could broaden students 'horizons and increase their knowledge. When reading, you should choose books that suit you and pay attention to the quality and depth of your reading in order to better improve your language and literary appreciation.
