陷阱
⚠️on a daily basis vs. daily：同义但语域不同
The safety inspector visits the construction site on a daily basis to check compliance with health and safety regulations.
✗
on a daily basis = every day（两者完全相同，可随意互换，没有语域差异）
✓
on a daily basis（每天，正式书面）和 daily（每天，较简洁，口语书面均可）含义相同，但 on a daily basis 更正式冗长，常见于报告/合同语言；daily 更简洁自然；此句 visits on a daily basis = visits daily，书面场合两者均可，但 daily 更简洁；on a basis 结构适合强调「以某种条件/方式」
安全检查员每天到访建筑工地，检查是否符合健康和安全法规。（on a daily basis = daily，正式语境前者更常见）
⚠️basis 复数 bases（不规则，× basises）
✗
The report identifies three main basises for the government's decision to reform the pension system.
该报告确定了政府改革养老金体系决定的三个主要依据。（× basises → ✓ bases，不规则复数）
basis 的复数是 bases（不规则复数，读 /ˈbeɪsiːz/，与 base 的复数 bases 拼法相同但读音不同）；× basises 不是正确复数
✓
The report identifies three main bases for the government's decision to reform the pension system.
该报告确定了政府改革养老金体系决定的三个主要依据。
