【Youhadbetter的反义疑问句】在英语语法中，"You had better" 是一个常见的表达方式，通常用于提出建议或警告。它后面常接动词原形，表示“你最好做某事”。然而，在实际使用中，有时需要对其提出反问，这就涉及到反义疑问句的构造。
一、总结
“You had better” 后面的反义疑问句，通常遵循以下结构：
- You had better + 动词原形，加上一个简短的反问部分。
- 反问部分的构成取决于前半句是肯定还是否定。
- 在“you had better”结构中，由于前面是肯定形式，因此反问部分通常用否定形式。

- You had better not be late, should you?
二、表格总结
| 原句结构 | 反义疑问句结构 | 说明 |
| You had better go. | You had better go, hadn't you? | “had better”为肯定结构，反问用“hadn't you” |
| You had better not go. | You had better not go, should you? | “not go”是否定结构，反问用“should you” |
| You had better call him. | You had better call him, hadn't you? | 肯定结构，反问用“hadn't you” |
| You had better not miss the train. | You had better not miss the train, should you? | 否定结构，反问用“should you” |
三、注意事项
1. “You had better” 实际上是“you had better do something”的缩写形式，其中“had”并非过去时，而是“had better”的固定搭配。
2. 在反义疑问句中，“hadn’t you” 和 “should you” 是最常见的两种形式，具体选择取决于句子的语气和语境。
3. 这类反问句通常带有提醒、劝告或轻微责备的语气，而不是真正意义上的提问。
