最簡單的問式就是把助動詞前移至主語的前面，從而形成問句。
- Will Jill come tomorrow?
- Have I found a new job?
- Is the house cleaned today?
簡單問句
在一般現在時的問句中，要搭配do/does。
you lives here變成問句就是：
- Do you live here?
Nancy has lunch at 12:30變成問句就是：
- Does Nancy have lunch at 12:30?
在一般過去時的問句中，要搭配did。
you sold the car變成問句就是：
- Did you sell the car?
但是，如果問句中who/ what/what是表示主語的話，就不能搭配do/does/did。
Jill telephoned Marco.（Marco是這句話裡的who，作賓語）
轉變成問句，可以搭配，變成
- Who did Jill telephone?
Marco telephoned Jill. (Marco是這句話裡的who，作主語)
轉變成問句，就不能搭配，變成
- Who telephoned Jill?
還有一種簡單問句叫“否定疑問句”（isn't it...?/ didn't you...?/ haven't we...?）。
我們用它來表示驚訝：
- Didn't you hear the bell, I rang it five times.
難道你沒聽到鈴響嗎？我都按了五次了。
或者是強調，希望傾聽者同意我們的看法：
- Isn't it a beautiful day today!
=It is a beautiful day today, isn't it?
今天天氣很好，不是嗎？
而且，在否定疑問句中，經常會被yes和no所迷惑。
Don't you want to go to the party?
你不想去派對嗎？
- Yes.=Yes, I want to go.對的，我想去。
（好多人會以為此處的Yes是肯定“不想去”的意思）
- No=No, I don't want to go. 是的，我不想去。
長問句
長問句，我自己的理解就是在問句中，至少會有兩部分組成，藉助其他句子進行提問，最常見的就是Do you know......?/ Can you tell me......?/ I wonder......?等句式。
如果是以這樣子的句式開頭，部分單詞的位置是要調整的，是區別於簡單問句的。比如：
簡單問句： Where has Nancy gone?
長問句： Do you know where Nancy has gone?
簡單問句： What time is it?
長問句： Do you know what time it is?
簡單問句：Who is that girl?
長問句： I don't know who that girl is?
簡單問句：Where can I find Lucy?
長問句： Can you tell me where I can find Lucy?
其次，特別注意簡單問句中使用了do/does/did的，在長問句中，是不需要的。比如：
簡單問句：What time does the film begin?
長問句： Do you know what time the film begins?
簡單問句：What do you mean?
長問句： I don't understand what you mean.
簡單問句：Why did Ann leave so early?
長問句： I wonder why Ann left so early.
