### Chinese: 但知识点基本不变，并不代表考试题型单一、试题重复。
### English: However, the knowledge point is basically unchanged, which does not mean that the test questions are single and the test questions are repeated.
### Errors: There is a major error at "knowledge point is basically". There is a minor error at "test questions are single and the test questions are repeated".

### Improved English: However, the unchanging basic knowledge points do not mean there can be single type or repetitive questions.
