Packed with 200 grammar topics and over 2800 annotated native-speaker audio examples, *Bootstrap Chinese Grammar* is a proven grammar-based approach that gets you communicating in Chinese precisely and with confidence. USER REVIEW: “***** Not your typical Chinese grammar app” : ‘At the time of writing I have 2060 consecutive days on Duolingo. During that time I’ve appreciated Duo for the vocabulary but found it very difficult to learn grammar. I’ve got a couple of grammar books (that I don’t have the time to properly study) and I’ve tried several grammar apps (that are characteristically poorly written, poorly explained and generally very unhelpful). I’ve learned more Chinese grammar from this app in three days than I have in the past five years. If you’re serious about understanding Chinese, this is the best £25 you’ll spend." -- Review by user JezDavis – Aug 26, 2023 * 'Bootstrap Chinese Grammar' provides the solid grounding in grammar basics that is the key to mastering Chinese as a second language. * Grammatical rules and concepts are clearly explained in order. Each topic builds on the last - step-by-step. * Hundreds of new words are introduced with clear contextual meanings alongside the grammar to help learners quickly build their Chinese speaking and comprehension prowess. STEP-BY-STEP TOPICS: Starting from the beginning, the idea is progress in small self-contained steps (called 'topics'). Each topic builds on the last, by incrementally adding new grammatical patterns, new vocabulary and lots and lots of useful examples. 3200 EXAMPLE PHRASES: Each topic includes a thorough explanation of the grammar and then lots of examples that illustrate the grammar. Each example includes an English translation, as well as notes highlighting how each example illustrates that topic's grammar, as well as the meanings of new Chinese words. INTERACTIVE EXERCISES: Once you have understood a grammar topic, you can immerse yourself in interactive drills designed for effective learning. Practice Chinese grammar with engaging exercises for rapid improvement. STUDY LIST: The app now Includes an integrated personal study list feature that streamlines your learning process -- improve your focus and achieve better results in your studies. THE COMPANION BOOK: The companion book is available called "BootStrap Chinese Grammar". The book includes all the content contained in this app - including 185 grammar topics and over 3200 example phrases. -- Just search for "BootStrap Chinese Grammar" on Amazon. -- The book and mobile app are easy to coordinate using QR codes. Just scan the QR code at the beginning of any chapter in the book with the app and it will take you straight to the topic where you will find all the examples with the high-quality audio matching the chapter in the book. -- So if you prefer to have the grammar set out in book form but would also like to be able to listen to the example sentences, then the book/app combination is perfect for you.
