What Happened 语法详解

What happened? 是英语中最常见的疑问句之一，用于询问刚刚发生的事件或情况。本文将从结构、时态、用法和常见错误等方面进行详细讲解。

1. 基本结构

What happened? 是一个特殊疑问句，由疑问词 what + 动词 happened（happen 的过去式）构成。

What + happened + (其他成分)?

例如：

• What happened?
• What happened to you?
• What happened at the party?

2. 为什么用过去时？

动词 happen 在这里使用过去式 happened，是因为我们通常在事情已经发生之后才提问。英语中，对已发生事件的询问自然使用一般过去时。

注意：happen 是不及物动词，不能用于被动语态。

3. 常见搭配

• What happened to...? —— 询问某人/某物遭遇了什么
  例：What happened to your phone?（你的手机怎么了？）
• What just happened? —— 强调“刚刚”发生的事
• Do you know what happened? —— 间接疑问句形式

4. 常见错误

• ❌ What did happen?（除非强调，否则不加助动词）
  ✅ What happened?
• ❌ What was happened?
  ✅ What happened?（happen 无被动语态）
• ❌ What happen yesterday?
  ✅ What happened yesterday?

5. 实用例句

1. A: You look pale! What happened?
   B: I fell down the stairs.
2. What happened to the meeting? Was it canceled?
3. I don’t know what happened — everything went black.
