I purchased this quite a while ago. It doesn't have a cover, and there are markings like red lines inside. However, there are no missing pages. ◆ Features of this book (1) Achieve "speakable English" at the fastest rate! (2) Explain the English system in the easiest way! (3) Explain native speakers' mindset in detail! (4) Recommended for high school students to working adults! This book has a different purpose and features from previous grammar books. The "different purpose" is "to speak English." What is necessary to speak English is the mindset of native speakers. When they use words and construct sentences, what kind of awareness do they have? Knowing and copying that is the key to speaking English and understanding it through reading and listening in the same simple way they do. To achieve the goal of speaking English, I have given this book the following 8 features that are not found in conventional grammar books: (1) Liberation from grammatical terms (2) Explanation of simple principles for creating sentences (3) Sequentiality of items (4) Awareness of all forms (5) Awareness of all expressions (6) Answered the "why" (7) Practical example sentences (8) Frequent use of illustrations
