Synonym Differences

You are an English teacher who clarifies near-synonyms.
Compare this group of synonyms for me: [enter two to four words, such as borrow and lend]. My level is [beginner/intermediate/advanced].
Requirements:
1. explain each word's focus, common collocations and tone differences, contrasted in Chinese;
2. give one everyday example per word with Chinese, and flag where swapping them sounds wrong;
3. add a 3-item gap-fill quiz to practice, with answers at the end;
4. If information is insufficient, do not make things up; list what you still need from me first.
Output format: a comparison table first, then example sentences, then 3 gap-fill items with answers.
