【語法】疑問句

🧩 一、基本結構：助動詞前置

肯定句 → 疑問句：把助動詞/情態動詞放到主語前面

規律：句中如果有 *be / do / have / 情態動詞(can, will, should…)*，就拎佢出嚟放前面。

🧭 二、特殊疑問句（問「誰、什麼、何時」嗰啲）

公式：疑問詞 + 助動詞 + 主語 + 動詞原形

例子：

• What do you want?
• Where did she go?
• Why are you crying?
• How can I help you?

特殊疑問詞只係多咗一個「領頭」位，後面結構同一般疑問句一樣。

✅ Be doing 疑問句 = 疑問詞 + be + doing

• 冇 do/does/did，因為 be 本身就係助動詞

✅ 疑問詞作主語

• Who is waiting?
• What is happening?

✅ 疑問詞作賓語

• Who are you waiting for?
• What are you doing?

⚙️ 三、主語係疑問詞嘅例外

當疑問詞本身就係主語時，唔需要倒裝。

• Who broke the window? ✅
• ❌ Who did break the window?（錯）

再睇：

• What happened? ✅
• ❌ What did happen?（錯）

⏳ 四、時態同助動詞嘅配合

🌀 五、反意疑問句（Tag Question）

用嚟確認、試探語氣；助動詞同主句對應。

當有插入語（如 do you think, do you suppose）時，疑問詞要放在句首。

插入語：去掉唔影響意思嘅就係插入語。但係去掉影響意思嘅，就唔適用。

適用嘅例如：

✅ do you think ✅ do you suppose ✅ do you believe ✅ do you imagine ✅ do you guess

• Where do you think he went? ✅

• What do you suppose happened? ✅

• Who do you believe did it? ✅

唔適用嘅例如：

✅ do you know ✅ do you remember ✅ can you tell me ✅ I wonder ✅ I don’t understand

• Do you know where he went? ✅

• Do you remember what happened? ✅

例如

✅ How long do you think I need to get there?

❌ Do you think how long I need to get there?

規則解釋

疑問詞 + do you think + 陳述句語序

當句子中有 do you think / do you suppose / do you believe 等插入語時：

結構：疑問詞 + do you think + 主語 + 動詞 …

英文只容許最外層疑問句倒裝，入面嗰層要保持「陳述句語序」。

更多例句

1. Where do you think he went? (你認為他去了哪裡？)
2. What do you think I should do? (你認為我應該做什麼？)
3. Who do you suppose will win the game? (你認為誰會贏？)
4. When do you think the meeting will start? (你認為會議幾時開始？)
5. Why do you believe she left early? (你認為她點解咁早走？)
6. How much do you think it will cost? (你認為會花多少錢？)

記憶要點

• 疑問詞永遠在最前面
• do you think 是插入語，放在疑問詞之後
• 後面用陳述句語序（主語 + 動詞），唔係疑問句語序

對比

可能出現兩個疑問詞的情況

1. 間接疑問句（Indirect Questions）

當主句本身有疑問詞，從句也有疑問詞：

✅ Who knows what he is thinking? (誰知道他在想什麼？)

✅ When did you decide where to go? (你幾時決定去邊度？)

✅ Why are you asking me how to do it? (你點解問我點做？)

✅ How can I know who did it? (我點知係邊個做嘅？)

✅ What do you think when we should leave? (你認為我哋幾時應該走？)

2. 選擇疑問句

✅ Who or what caused the problem? (係邊個定係咩嘢導致問題？)

✅ When and where did you meet him? (你幾時同喺邊度見到佢？)

3. 複合疑問

✅ I don’t know what to do or where to go. (我唔知做咩好，又唔知去邊度)
