Grasping the foundation of high school English, grammar is often the foundation of high school, and so is English learning. College English is mainly a deeper expansion and deepening, and the foundation remains unchanged, so it is very important to lay a solid foundation.
The college entrance examination is only distinguished for English graded teaching. All the knowledge before college is examined. If you want to do well in the exam, you can use the summer vacation to review the English you have learned before, no problem. It's just that some schools may take compound dictation in listening, which can be specially prepared.
Some college entrance examinations are for placement, and top students enter experimental classes. If you are not an English major, you may divide English into three classes: Fast, Middle and slow three, or implement different teaching methods according to students' English level, because English is a compulsory course for any major.
In general, this kind of entrance examination is not difficult. Not to mention non-majors, the placement test of the English department at that time was almost as difficult as the college entrance examination, except for one more composition dictation. Non-professional exams are relatively easy, and the questions should be selected in the relatively simple part of CET-4, which may not be as difficult as the college entrance examination.
It is suggested that you can read some books in CET-4 during the summer vacation and get familiar with the questions. It's been a while since the college entrance examination, and some knowledge of high school may have been forgotten, so it may be a little difficult to read the CET-4 books. You don't need to make the CET-4 book as thorough as coping with the college entrance examination, but you must read the general idea and classic examples and be impressed. Because the ultimate goal of college English is to deal with Band 4, the entrance examination will also take Band 4 as the key link. If you have a general understanding of CET-4, you can make preparations in advance to nip in the bud.
