Band 4 mainly remembers vocabulary, and words are not afraid to remember anything. You can use the root memorization method of CET-4 and CET-6 to remember words.

Reading is also very important, accounting for a large proportion, so you should focus on training the quality and speed of reading.

Besides, the form of listening is different from the college entrance examination. There are only options on paper, so there is no problem. You have to listen to the questions by yourself, get used to it first.

If you write a composition, it is estimated that your basic skills are relatively high, mainly by memorizing vocabulary. People who have studied grammar in high school are generally fine.

There are cloze, translation and so on. These all need to memorize vocabulary. There are many vocabulary books on the market. You can read what you like and buy them.

To sum up, I suggest you use Spark's "New Questions of CET-4". This book is comprehensive, from listening to composition to reading, rich in content, good in topic selection and comfortable in typesetting.
