LEARN CHINESE GRAMMAR – STEP BY STEP, BEGINNER TO ADVANCED Bootstrap Chinese Grammar takes you through Mandarin grammar in 204 short, clear topics, with over 2,800 example phrases recorded by a native speaker. Understand how Chinese sentences work, then practise until it sticks – so you can speak and understand Chinese precisely and with confidence. STEP-BY-STEP TOPICS Start at the very beginning with 是 (shì) and 不 (bù) and build up one small, self-contained step at a time: questions with 吗 and 呢, measure words, 了 and 过, comparisons with 比, resultative and directional complements, 虽然…但是, 越来越, 连…都 and much more – right through to everyday idioms. Each topic explains one grammar point in plain English, then adds new patterns and new words on top of what you already know. EXAMPLES YOU CAN HEAR AND READ Every topic has plenty of examples, and each one comes with: • Simplified characters and pinyin, written with the tone changes you actually hear • An English translation • Notes showing how the example uses the grammar, with the meanings of new words • Native-speaker audio, at normal or slow speed Tap any word to hear it on its own and see its pinyin and meaning. Pinyin is coloured by tone, and you can hide it to test your reading. EXERCISES FOR DEEP LEARNING Once you understand a topic, practise it: • Phrase builder – put the words of each phrase in the right order • Multiple choice – pick the missing word • "Why?" – make a mistake and see exactly what went wrong NEW: LISTENING & TONES A second set of exercises in every topic trains your ear: • Build each phrase from its audio alone • Hear a word and pick its tones NEW: SPACED REPETITION Every phrase you practise comes back for review just before you're likely to forget it – the next day, then after a few days, a week, and longer. A few minutes a day keeps everything you've learnt fresh. AUDIO REVIEW Play through a topic's phrases hands-free with voice commands ("play", "slow", "next", "meaning"). Record yourself and compare with the native speaker, or set it on auto-play, lock the screen and listen with your phone in your pocket. THE COMPANION BOOK Prefer to study from a book?
