He is happy 變成 why is he happy ?
將 Be 動詞句子改為 Why 疑問句 (Changing Be-verb sentences to Why-questions)
基本規則 (Basic rule):
當將含有 be 動詞的陳述句改為 "why" 疑問句時，我們需要將 be 動詞移到主詞前面。
例句：
- "The unified data platforms are essential." (統一資料平台是必要的。)
轉換成 why 疑問句：
- "Why are the unified data platforms essential?" (為什麼統一資料平台是必要的？)
語法解析 (Grammar analysis):
- 加上疑問詞 "why" 置於句首
- 將 be 動詞 (are) 移到主詞 (the unified data platforms) 前面
- 保留句子其餘部分不變
其他時態的例子 (Examples with different tenses):
現在式 (Present tense):
- 陳述句："The meeting is important." (這會議很重要。)
- 疑問句："Why is the meeting important?" (為什麼這會議很重要？)
過去式 (Past tense):
- 陳述句："The project was delayed." (專案被延後了。)
- 疑問句："Why was the project delayed?" (為什麼專案被延後了？)
未來式 (Future tense):
- 陳述句："The new system will be implemented next month." (新系統將於下個月實施。)
- 疑問句："Why will the new system be implemented next month?" (為什麼新系統將於下個月實施？)
中文學習者常犯的錯誤 (Common mistakes by Chinese speakers):
錯誤用法 (Incorrect):
- "Why the unified data platforms are essential?" ❌ (未將 be 動詞移到主詞前)
正確用法 (Correct):
- "Why are the unified data platforms essential?" ✓ (為什麼統一資料平台是必要的？)
練習範例 (Practice examples):
- 陳述句：The database security is crucial. 疑問句：Why is the database security crucial? (為什麼資料庫安全至關重要？)
- 陳述句：The software updates were postponed. 疑問句：Why were the software updates postponed? (為什麼軟體更新被延後了？)
