This study analyzes and evaluates the textbooks based on the four sets of college English textbook corpus on account of the word family, and discusses their inter-discourse lexical growth patterns, lexical density and word families of CET4 and CET6. The coverage rate and the inter-discourse vocabulary repetition rate of the word family tables in each textbook are take into account in evaluation. The results show that the Brunet model has a good fit to the vocabulary growth curve of the four sets of textbooks. This model can be used to predict the vocabulary coverage of the four sets of textbooks for natural texts of any length outside the textbook. The overall difference in vocabulary density of the four sets of textbooks is not very large, but some textbooks are not arranged according to the difficulty of each book; four sets of textbooks can not completely cover the CET4 and CET6 family table, moreover, two-word family table has lower inter-discourse vocabulary in the four sets of textbooks. On the basis of qualitative analysis, using the corpus as a means to quantitatively analyze the vocabulary of the 21st Century College English Applied Comprehensive Course, and to calculate the relatively objective evaluation results, I hope to bring some new ideas to the current textbook evaluation. And provide some reference for the design and preparation of the textbook.
