文法句型
how + that-clause (formal)
用法筆記
In this sense, 'how' can be replaced by 'that' without changing the meaning. Most common in formal letters, legal documents, and literary narratives rather than everyday conversation. Often used after verbs of reporting such as 'explain', 'mention', 'write', 'inform', and 'describe'.
常見錯誤
❌ 'I told him how I was going to the store.' (if meaning 'that' in casual speech) — This is grammatically correct but sounds overly formal in casual conversation; use 'that' instead for everyday contexts.
