My composition in high school is very unstable, and I didn't find the book until two months before the college entrance examination. After reading the book, I marked the highlights inside, memorized them roughly, analyzed the format of the model essay, and then applied it. At first, one composition per week was stable above 46 points, and with the improvement of proficiency, the score was higher and higher. Later exams were all above 52 points. I got at least 54 points in the college entrance examination. Although I can't get full marks, I am still very satisfied with my short-term results in two months.
I have read many kinds of books before. In my opinion, prose poetry can make some sentences in the article shine, but not all teachers will like it after writing the composition. The same article may be 55 points or 35 points, which is risky and difficult to grasp. You can read in moderation, improve the elegance of sentences and increase the brilliance of articles, but remember that the key point is sentences, and don't learn to write. Readers and Youth Digest are totally entertainment magazines. The stories in them are just for reading, not profound, and the stories are too complicated to sort out. It is suggested to buy a book with composition materials, classify various examples, and there are beautiful poems in it, which can be applied to the text.
Actually, I think it's better to be steady. If the intention is too deep, it is easy to digress. The teacher will talk about innovation, but what he didn't expect after writing it is partial, and innovation is too uneconomical.
These are my personal suggestions to improve your composition score, and I hope they can help you. I wish you good results in the college entrance examination!
