文法句型

required + noun

用法筆記

Frequently placed directly before a noun ('the required documents', 'required training'). Not normally used with degree intensifiers like 'very' — 'very required' sounds unnatural. Use 'strictly required' or 'absolutely required' instead to show strong necessity.

常見錯誤

❌This training is very required for the job.
✅This training is strictly required for the job.
💡Use 'strictly', 'absolutely', or 'legally' with 'required'; avoid 'very' as a modifier.
❌She did the requirement training before starting.
✅She did the required training before starting.
💡'Required' is the adjective form; 'requirement' is a noun and cannot modify another noun.
