As someone who loves reading novels, I have no practical experience or use any speed reading materials. But as far as I know, there are many different speed reading materials to choose from, including novels, essays, and other literary works. Different teaching materials may provide different characteristics and techniques, so it is best to choose the right teaching materials according to your own needs and interests. In addition, speed reading materials weren't the only learning resource. Reading, writing, and other learning activities could also be used to improve one's literary attainment.
