A Corpus-Based Study on the Evaluation of Integrated College English Textbooks Vocabulary

This paper aims to make vocabulary evaluations on 64 reading texts of four volumes in New Horizon College English for Reading and Writing (NHCERW) in the empirical corpus-based method. Results showed that NHCERW has good coverage of basic requirements in College English Curriculum Requirements. The rate above 94% of all the tokens in four books covered most vocabulary at the basic level. The study also gave some suggestions: First, this set of textbooks is suitable for students whose knowledge is not consolidated. Second, teachers whose students have chosen NHCERW can delete certain teaching materials and supplement some more difficult reading materials. Third, compliers should try to increase the vocabulary difficulty of NHCERW to make it close to Intermediate Requirements at least in Book 4. What's more, compliers should consider adjusting the readability of texts in Book 2 and Book 3.
