do / does / did 疑問句
初級Questions with do / does / did
構成與用法
do/does/did + 主語 + 動詞 — 一般時態的提問
1.什麼時候需要 do / does / did
含有普通動詞（work、like、go、want…）的句子，不能把這個動詞提到前面來構成疑問句，而要借用助動詞 do / does / did。
| 時態 | 主語 | 助動詞 | 例句 |
|---|---|---|---|
| 一般現在時 | I / you / we / they | do | Do you like spicy food? |
| 一般現在時 | he / she / it | does | Does your brother drive? |
| 一般過去時 | 所有主語 | did | Did they call you? |
含有 be、can、will、have got、should… 的句子不用 do——直接把這個動詞提到前面：Are you ready? Can she swim? Have you got a pen?
2.語序
（疑問詞）+ do / does / did + 主語 + 動詞原形 + 其他部分？
| 疑問詞 | 助動詞 | 主語 | 動詞 | … |
|---|---|---|---|---|
| Do | you | live | near here? | |
| Where | does | your sister | work? | |
| What time | did | you | get | home? |
| How often | do | they | visit | you? |
| Why | didn't | he | come? |
助動詞承擔時態和人稱（does = 一般現在時、he/she/it；did = 一般過去時），所以主要動詞永遠用原形：Does she speak…? Did you see…?
3.以介詞結尾的疑問句
日常疑問句中，屬於動詞的介詞通常放在句末。
Who do you live with?
你和誰一起住？
Where does she come from?
她是哪裡人？
What did you talk about?
你們聊了什麼？
4.否定疑問句
用 don't / doesn't / didn't 表示驚訝，或者期待對方同意你。
Don't you like it?
你不喜歡嗎？
Why didn't you tell me?
你為什麼不告訴我？
5.當 who / what 是主語時
如果 who / what 是做這個動作的人或物（即主語），疑問句裡沒有 do/does/did，動詞和普通陳述句一樣。另見“主語疑問句與賓語疑問句”一課。
Who called you?
誰給你打電話了？（who = 打電話的人；不說：Who did call you?）
Who did you call?
你給誰打電話了？（who = 被打電話的人）
What happened?
發生了什麼事？
6.常見錯誤
You like pho?Do you like pho?
書面英語需要助動詞（省略它只是隨意的口語說法）。
Where she works?Where does she work?
缺少 does，而且語序錯了。
Did you went out?Did you go out?
did 後面用原形。
Do you can help me?Can you help me?
有 can 的句子不用 do。
Does she is a doctor?Is she a doctor?
有 be 的句子不用 do。
例句
- Does your sister work in a bank now?
- How often do you eat out?
- Do you have a pen I can borrow?
- Do you like spicy food?
