常見錯誤
What are common mistakes with "Brother"?Which "Brother" sentences look correct but are wrong?
×I have two brothers. They are my older brother and younger brother.
✓I have two brothers. They are my older brother and younger brother.
雖然文法正確，但在英語中重複使用 'brother' 聽起來冗餘。通常會用 'elder' 和 'younger' 或直接說出名字來區分。
×He is brother of my friend.
✓He is my friend's brother.
表示所有格關係時，應使用所有格形式（'s）或 'of' 結構，但 'brother of my friend' 在口語中較不自然。'my friend's brother' 是最常見且自然的說法。
×We are brother.
✓We are brothers.
'Brother' 是可數名詞。當主詞是複數（we）時，表語也必須使用複數形式 'brothers'。
×He is a brother.
✓He is my brother. / He has a brother.
單獨使用 'a brother' 意思模糊，可能被誤解為「他是一名修士」或語意不清。若要表達家庭關係，應使用所有格（my, his, her）或明確上下文。
×My brother is older than me five years.
✓My brother is five years older than me.
比較年齡差距時，英語的語序是「數量 + 時間單位（years, months） + 比較級形容詞（older）」。
×I and my brother went shopping.
✓My brother and I went shopping.
英語中，出於禮貌，提到自己和他人時，通常將 'I' 或 'me' 放在最後。且當 'I' 作為主詞時，應使用主格 'I' 而非受格 'me'。
