### 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, no change in knowledge points does not represent for single exam question types and repetition of questions.
### Errors: There is a major error at "no change". There is a major error at "knowledge points does not represent for single exam question types and". There is a minor error at "tion of".

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