直接疑问句是提问时最常用的句式，在询问简单信息和复杂信息时均可使用。
Eg:
When do you get to work?
Do you like fish?
How long have you been working on this project?
Where are those ties manufactured?
二、是否问题：（Yes / No Questions）
助动词Auxiliary + 主语Subject + 动词Verb Form + (宾语objects) + ?
是否问题常用来询问简单信息，针对性较强，提问人往往只需要得到对方肯定或否定的答复即可。
Eg:
Does he live in New York?
Have you seen that film?
Is she going to come to the party?
三、如何就主语或宾语提问：(Subject or Object Questions)
例如：Jason likes playing golf. 如果我们想就这句话中的某种信息进行询问或确认，就可以使用下列句式：
问主语——Wh? + (auxiliary) + verb + object?
Who likes playing golf? - ANSWER Jason
问宾语——Wh? + auxiliary + subject + verb?
What does Jason like playing? - ANSWER golf
Eg：
Who enjoys playing tennis?
Who is coming to the party next week?
就主语提问的常见形式还有：
Which
Which bicycle goes fast?
What kind of
What kind of cheese tastes mild?
What sort of
What sort of tea costs very little?
Who
Who goes to school here?
四、反意疑问句（Question Tags）：
反问句借助疑问号和疑问语气提问，这种方法常用来确认某些你已经了解到信息或你认为你已掌握的信息，也可以用于检验你是否已经完全理解了对方表达的意思。
构造反问句的方法是：在一般陈述性的语句后写上逗号，再构造与前文相反的陈述（前文为肯定陈述，后文则需否定；前文为否定，后文则需肯定），最后加上疑问号表达疑问含义（口语中还需使用疑问语气）。
Examples:
You're married, aren't you?
He's been here before, hasn't he?
You didn't buy the new car, did you?
Examples:
I was wondering if you know the way to the nearest bank.
Do you know when the next train leaves?
常见句式主要有：
Do you know...
I wonder / was wondering ....
Can you tell me...
I'm not sure...
I don't know...
Do you know when the next train leaves?
I wonder when he will arrive.
Can you tell me where he lives?
I'm not sure what he wants to do.
I don't know if he is coming.
