In the process of literature reading, we should learn and develop the habit of purposeful and focused reading, so that we can be good at discovering key points, new problems, new ideas and new materials when reading. In the process of reading or after reading a book, you should learn to take some reading notes, record the ins and outs of the book, the main characters, deeds and reading feelings, and also extract some beautiful words. For example, paragraph: the most convenient way to grasp the meaning of a paragraph is to grasp the "main sentence", that is, to grasp the sentence that explains the main meaning of the whole paragraph. Secondly, grasp the context of the article: some articles explain the central idea in the title, some point out the central idea at the beginning and end of the article, and some express the central idea through major events, as long as the central idea can be quickly determined according to major events. Thirdly, we should consciously remember the main characters, deeds, opinions and central ideas in articles and books, form our own mind map and promote better understanding.
