First of all, I think we can practice with real questions and get familiar with the contents of each module of CET-4, as well as the contents examined in each content, such as listening. Listening multiple-choice questions mainly examine our ability to refine words, and the answer is actually the focus of two people's conversation. The lyrics part of the listening part mainly examines our ability to grasp words and key points, especially the dictation of sentences, which is to exercise your ability to a great extent. So here I suggest you listen to the exam questions several times and then read the original text by yourself. By listening, we can improve our ability in a short time.
The reading part mainly examines your ability to refine the key points of the article. Cloze and error correction mainly depend on your grammar. After finishing, it is suggested that you can look at the analysis more, so that you can not only gain knowledge, but also consolidate these problems and review your weaknesses repeatedly.
The final composition and translation part mainly examines your comprehensive ability. This group won't improve much for a while, so we can only look at the routine of writing articles, imitate more and practice more. I believe that as long as you work hard, you may be able to write a qualified article within seven days.
We know what each module needs to check. Next, we practice each module by doing real questions. What needs to be said here is that when doing real questions, I suggest that everyone pinch their watches, so as to really simulate the exam and not let us panic during the exam.
Finally, my suggestion is, don't lose heart in this failure, and continue to implement this learning attitude. I believe you will get good grades next time.
