For students who study Chinese as a foreign language, it''s crucial for them to enlarge the scope of their reading to improve their comprehension skills. The "Rainbow Bridge" Graded Chinese Reader series is designed to provide a collection of interesting and useful Chinese reading materials. This series grades each volume by its vocabulary level and brings the learners into every scene through vivid storytelling. The series has the following features:
I. A gradual approach by grading the volumes based on vocabulary levels. We have consulted the New HSK Vocabulary (2012 Revised Edition), the Graded Chinese Syllables, Characters and Words for the Application of Teaching Chinese to the Speakers of Other Languages (National Standarat) and the 1,500 Commonly Used High Frequency Chinese Vocabulary, along with the Common European Framework of Reference for Languages (CEFR) to design the "Rainbow Bridge" vocabulary grading standard. The series is divided into seven levels (Starter*, Level 1, Level 2, Level 3, Level 4, Level 5 and Level 6) for students at different stages in their Chinese education to choose from. For each level, new words are no more than 20% of the vocabulary amount as specified in the corresponding HSK and CEFR levels. As the levels progress, the passage length will in turn increase. The following table indicates the corresponding "Rainbow Bridge" level, HSK and CEFR levels, the vocabulary amount, and number of characters.
