To write a good essay on the topic, we should pay attention to the following points: First, grasping the style of the essay on the topic is often not limited to the style, so that candidates can play freely. However, unlimited style does not mean no style. The "unlimited style" of topic composition is actually not limited to one style, so that students have the freedom to choose a style. When you choose a style, you must write according to the characteristics of this style. Some students have strong observation ability and rich life accumulation, so they might as well extract the wonderful fragments of life and write vivid and touching narratives; Some students are imaginative and good at writing stories. They might as well write fairy tales, fables or science fiction. Some students have strong logical thinking ability and are good at reasoning, so they might as well write an argumentative essay with sufficient reasons; Some students have delicate and rich feelings, so they might as well write a beautiful essay to express their feelings, which will be excellent. Second, narrow the topic composition only provides the topic of writing, and there are no restrictions on center, material, structure, style and language. It gives candidates a relatively open thinking space, allowing candidates to maximize their imagination and creativity. However, if we don't pay attention to the topic and narrow the gap in writing, there will be a problem of "writing thousands of words and pulling Wan Li". Therefore, no matter how broad the topic is, we should be good at narrowing the "encirclement circle" and choosing small groups, such as one thing, one person, one thing, one feeling, one opinion and so on. Concentrate on the breakthrough, write the topic of your choice in detail and thoroughly, and achieve "seeing the big from the small".
