First, on the basis of being familiar with the original text, think deeply and imagine reasonably. Because the expansion is based on the original text, the main characters and events have been determined, and we can't make up the process without the original text, let alone change the central idea of the original text. Therefore, when expanding writing, we should first be familiar with the content of the original text. On this basis, we can closely follow the central idea of the original text, grasp the main plot, think deeply about what the original text is not clear about, or what it is not written specifically enough, ask more "how", carry out reasonable imagination and enrich the content of the article.
Second, the expanded article is more specific, vivid and vivid than the original. In order to make the article more concrete, vivid and vivid, it is generally necessary to change the narrative of the original text into description. Can increase the description of the environment and the description of the appearance, manner, movement and psychological activities of the characters. You can also add some details according to your own imagination, and you can also add some discussion or lyric content appropriately.
Third, we should prevent the content from being crammed or the language from being repeated because of the need to lengthen the space. At the same time, when writing, you can regenerate the branches of the original text and generate new branches. However, the backbone of the original text generally does not need to be moved, so as not to change the original intention and lose the meaning of expansion.
For example, the development of "The Mantis Catching Cicada" can describe the detailed process of mantis catching cicada in detail, personify the animals and make the movements vivid. The key is to write a good psychological description of mantis. If you write a good article, you will be able to shine and deepen the theme of the article. Expanding writing requires expanding imagination, being good at digging and expanding capacity. A common problem of primary school students' composition is that their ideas are not broad and their methods are single, and they are often finished in a few words from one direction, one angle and one level. Therefore, we should make great efforts to clarify our thinking and describe it. (1) Read the original text and make sure that the development of the central idea can't be separated from the meaning of the question and the main content and central idea of the original text, and start a new stove. Therefore, it is necessary to guide students to carefully analyze the requirements of the topic and the materials provided: whether to remember people or write scenery. On the basis of clarifying the basic elements and main contents, grasp the central idea of the material and take it as the central idea of the expanded text. (2) Divide the levels of the original text and determine the focus of expansion, which is paragraph expansion or article expansion. It is necessary to divide the levels in a certain order as the basis for amplifying paragraphs, and pay attention to the key levels. Let the students understand that the expansion of the original text is not to be carried out everywhere, but to determine the focus of the expansion according to the central content. For example, on Sunday, Xiaoming went to Xinhua Bookstore to buy Modern Chinese Dictionary. Unfortunately, however, Xiao Ming was very anxious just after reading the book. Aunt Liu, the shop assistant, asked Xiaoming to leave her address, saying that she would look for it in the warehouse and inform Xiaoming if there was any. In the evening, it began to rain heavily. Aunt Liu sent a modern Chinese dictionary to Xiaoming's family, and Xiaoming was very moved. There are two related things in the material: one is that Xiaoming went to the bookstore to buy books, and the other is that Aunt Liu came to deliver books. This article mainly praised Aunt Liu's painstaking efforts and excellent quality of serving readers wholeheartedly. Therefore, the focus of expansion should be "Aunt Liu delivers books in the rain". (3) Expand imagination, learn to describe and determine the center, level and expansion point of the original text, and then expand imagination. Generally, the expanded materials are general, so students should be inspired to integrate their daily experiences and feelings into the expanded content based on the central idea of the original text, and associate relevant plots or details according to their own life experiences. When expanding writing, students can be guided to grasp key words and key sentences, and narrate or describe them by decomposing or asking questions. When writing things, we should fully develop the main plot and write out the cause and effect, development and changes; When writing a character, we should express the character characteristics by describing the appearance, manner, language, action and psychology of the character. When writing a scene, we should grasp the shape, state, color and sound of the scene to describe it in detail and express the characteristics of the object.
