Can you help me find a sketch about science?

Scientific papers are also called knowledge papers or literary discourses. It adopts the style of prose, that is, with the help of some literary writing techniques, it vividly expresses the scientific content. Scientific papers are written in literary style, which is scientific, informative, interesting and entertaining, and enables readers to gain scientific knowledge in literary appreciation. Science and technology sketches are generally short and pithy, easy to understand, rich in language and lively in form. Reading such articles can activate thinking, enrich knowledge and broaden horizons, which is very popular with readers. With the rapid development of high technology and the popularization of scientific knowledge, the social demand for scientific papers is increasing day by day, and the social benefits are becoming increasingly obvious. Scientific papers have become the content that people like to write and read. In recent years, the proportion of scientific papers in various examinations is getting higher and higher, and there are new attempts and innovations in content, form and proposition design. Therefore, in the study of expository writing, the value of scientific papers can not be ignored, and we should pay more attention to it. 2. Main features of scientific papers A. The scientific nature of scientific papers is very important. The content must be scientific, the quoted materials must be reliable and the data must be accurate. The purpose of writing scientific sketches is to popularize scientific knowledge to people. If the knowledge introduced is unscientific, it will not only fail to achieve the purpose of writing, but also have a very bad influence. For example, there is a scientific sketch "potted flowers should not stay indoors for the night" on the grounds that plants should inhale oxygen and exhale carbon dioxide at night, which is harmful to people's health. In fact, the carbon dioxide exhaled by every 300 square meters of leaves is equivalent to the amount exhaled by a person. It can be seen that putting a few potted flowers indoors for the night will not affect people's health. B. the vividness of words. The vividness of writing is the main sign that scientific papers are different from general expository articles. How to make the writing of scientific papers vivid? One is good at narration and description. For example, it tells a fairy story about the Dead Sea, and there are many wonderful descriptions about the strange peaks and caves in Guilin. The second is to be good at interspersed anecdotes. For example, inserting a fairy tale into the Dead Sea vividly describes the situation that people don't sink in the Dead Sea, and illustrates the scientific truth of the buoyancy of the Dead Sea water from the side. For example, in the article "The Language of Human Beings", two sentences were inserted into the composition of the master elder brother when he was in primary school, which made the writing relaxed and lively. Third, be good at using rhetoric. Read the expositions in Unit 2 and Unit 7 carefully, consciously find out the rhetorical methods used in the text and taste its language characteristics. Because some scientific knowledge is not easy to understand, being good at using figurative rhetoric methods can make scientific principles easy to understand, easy to introduce and popularize scientific knowledge. C. Popular science prose is not for professional scientific research, but for popularizing scientific knowledge. Therefore, they must explain, introduce and express scientific content in simple terms. For example, human language, tea, Shi Tian and other articles are characterized by easy-to-understand content. 3. The form of scientific sketch. With the extensive content of scientific sketches, from basic particles and atoms invisible to the naked eye to the huge earth and sun; No matter in industry, agriculture, physics, chemistry, astronomy, geology, biology and so on. , you can find the theme of scientific sketches. Therefore, the representation of sketch must be diverse and flexible. But to sum up, there are the following common types: a. Descriptive description refers to description; Narrator refers to narration. This kind of sketch is rich in imagination and beautiful in language, with vivid description and narrative; The style of literary prose aims at introducing scientific knowledge. For example, Guilin with strange peaks and caves is one of the most typical examples. This description is convenient to say that from ancient times to the present, the circumstantial evidence is extensive and interesting, attracting readers. B. Self-report Self-report is to give people's thoughts, feelings, language and actions to the scientific knowledge to be introduced by the first person personification, so that the explained things can stand up and introduce themselves. For example, topics such as "dust self-reporting" and "I am electricity" are self-reporting. C. Storytelling is a form of expression that compiles the scientific knowledge to be introduced into vivid and interesting stories, so that people can acquire scientific knowledge when reading or listening to stories. It is different from self-report and uses the third person; Similarly, anthropomorphic methods are mostly used. Using this form, we should not only make the story fascinating, but also pay attention to its rationality. When you tell a story on the phone, you should explain the time and place. "People" is to personalize the things mentioned and have a plot. In terms of expression, narrative and description are generally equally important, and the language is vivid and vivid. Of course, we can't just emphasize stories and ignore scientific knowledge, and the meaning of writing will be lost. D. Conversational conversation, also known as dialogue, is explained in the form of question and answer and dialogue. This way gives people a kind of cordial and real feeling, which is easy to communicate with readers and produces a * * * sound. At the same time, this writing is easier to refine. Conversations are generally divided into three types: question and answer, dialogue between Party A and Party B, and dialogue in the text. The first two are more common and easy to master. The second is to organize the dialogue between characters into concrete stories. The development of storyline is mainly driven by the change of dialogue content, and dialogue is the main body of the article. In short, no matter which form is adopted, it depends on the content, highlighting description as the main line and integrating narrative, description, lyricism and even discussion. It looks like prose, but it is actually an explanation. The infection of literary brushwork achieves the purpose of explanation and is more readable. Several texts selected in Unit 2 and Unit 7 of Book 4 are very literary, but their forms are relatively simple. The Dead Sea is not dead, the rest are descriptive. There is no dialogue, self-report and other forms. It is also necessary to accumulate articles in future reading and enrich the reading content.
