This book is good, but it is not realistic to finish it in a short time and improve your writing level. As we all know, the improvement of composition level is not achieved overnight, but the result of accumulation over time, so it is of course no problem to read good books, or you can look at crazy reading. But reading a book should not just read, we need to think about the contents. For example, why is this composition written like this, what kind of structure is used, and what words are used. These are all worth thinking about, so generally speaking, books can be bought, which is helpful to improve the writing level.
