### Chinese: 但知识点基本不变，并不代表考试题型单一、试题重复。
### English: But the knowledge points are basically unchanged, and do not mean that the exam is single and the test is repeated.
### Errors: There is a major error of incorrect translation is missing content from the correct translation at "the exam is single and the test is repeated". There is a major error of incorrect translation has stylistic problems at "knowledge points are basically unchanged". There is a major error of incorrect translation includes information not present in the correct translation at "and do not mean that".

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