I want to know about the question analysis and test skills of CET-4. Who can tell me?

Personally, listening and reading are more difficult, because I didn't take listening in the college entrance examination that year, and as a result, I have to take CET-6 listening in the final exam of college English. Regarding listening and reading, I suggest reciting more words, and then brushing the questions to improve my English slowly. Memorizing words can be done by Flash English "Level 4 Word Flash", which is rich in vocabulary, and can also be divided into frequently tested words, basic words, occasionally tested words, and super-category words. It is focused, time-saving and efficient. If the foundation is general, the resource book recommends "Detailed Explanation of Level 4 True Questions". Reading is explained word by word, and long and difficult sentences have grammar diagrams. It is easier to supplement vocabulary and grammar foundation by separating sentence structures one by one.
