Introduction
在英语中，疑问句是指需要回答问题的句子，换句话说，就是询问信息的句子。疑问句的构成和分类多种多样，下面我们将探讨不同类型的疑问句。
Yes/No Questions
Yes/No Questions，或称为polar questions，是最基本的疑问句类型。它们通常以“do/does/did”、“is/are/am”、“will/would/can/could”等助动词开头，例如：
Do you like cheese?
Is he coming to the party?
Did she finish her homework?
这类疑问句只需要用一个肯定或否定的回答即可，例如“Yes, I do.” 或 “No, she didn't.”
Question Words Questions
Question Words Questions是对特定信息询问的疑问句类型，问句一般以疑问词（如what, where, when, why, how, who等）开头。例如：
What are you doing?
When is the meeting?
Why did he leave?
How did you get here?
这类疑问句需要提供详细的回答。回答要根据问题所询问的内容进行组成，例如“我正在写一篇文章。”或“会议在下周三下午两点。”
Choice Questions
Choice Questions是对两个或多个选项之间进行选择的疑问句类型。这类疑问句通常以“or”连接两个或多个选项。例如：
Do you want coffee or tea?
Are you going to the beach or the mountains?
这类疑问句需要选择一个选项作为回答，例如“我喜欢咖啡。”或“我会去山里。”
Tag Questions
Tag Questions是在问句最后的总结加上相反的陈述句，以求证或暗示对方同意的疑问句类型。例如：
You don't like broccoli, do you?
This is a great movie, isn't it?
这类疑问句需要给出相符合的肯定或否定答案，例如“Yes, that's correct.” 或 “No, I actually don't like it.”
Conclusion
疑问句在英语中是非常常见的。无论是Yes/No Questions, Question Words Questions, Choice Questions 还是 Tag Questions，都是交流中必不可少的工具。了解这些类型并掌握它们的用法，能够帮助你更流利、更自然地进行英语交流。
