This book is only in pure English for Level 4, with no explanation. I think it is enough to be able to immediately know the meaning of an English word when you take the CET-4 exam. Most people will use some common words when they want to translate and write words, and will not use rare words. Therefore, Baozimen who have only pursued CET-4 must immediately react to Chinese words when they see them. Listening is also important!
Purpose: I wish Level 4 students to pass every exam
