新概念英语全四册

新概念英语全四册 is a comprehensive English learning app based on the classic New Concept English textbook series. It supports learners from beginner to advanced levels with structured lessons covering listening, speaking, reading, writing, grammar, translation, and vocabulary.

Key features include bilingual Chinese-English audio, sentence and passage looping, animated videos for Books 1 and 2, lesson vocabulary with dictionary access, vocabulary lists, and detailed teacher-led video explanations. The built-in vocabulary book supports English-only or Chinese-only display, random or alphabetical sorting, and interactive memorization. Learners can also switch between day and night modes while studying. Watching a short video each day can remove advertisements for the rest of the day.
