English learning is a long-term comprehensive process. There is no way to say what you can do by learning a textbook. Learning methods are also very important. Just reading the words that have been memorized in the glossary is completely different from reciting all the new words, expression exercises and key paragraphs after class. What's more, learning intensive reading textbooks can only solve the problems of reading and part of writing. It has no effect on listening and speaking. You have studied hard, you may have read very well in the exam, but you still can't understand a word in your listening. Let's answer your question: this textbook is not simple, and the difficulty climbs quickly. 1 basically, it is the college entrance examination to Band 4. I remember when I was a freshman, I thought it was very simple. I could eat all the books in high school. Basically, the difficulty begins, and after learning, it is probably the sixth grade level. 3 and 4 are more difficult, and there are many literary and artistic things. There are also many new words. Study hard and you should reach CET-6 or CET-4. After careful study, you can at least reach a good or even excellent level and lay a good foundation for TEM-8. But I strongly recommend that students of other majors use this textbook to teach themselves. The text is very long and contains a lot of content. But also in line with the teaching direction of English majors: it is very literary. There are many excerpts from essays, short stories and novels. Learning efficiency is low, and it is likely that you will not be able to persist. The suggestion is to brush a lot of questions to prepare for the exam.
