【notonly的倒装用法】在英语语法中，“not only... but also...”是一个常见的结构，用于强调两个并列成分。然而，在某些情况下，为了强调或使句子更正式，可以将“not only”置于句首，并使用倒装语序。这种用法被称为“not only”的倒装用法。
以下是对“not only”的倒装用法的总结和示例说明：
一、基本用法与倒装结构
| 原句结构 | 倒装结构 | 说明 |
| He is not only intelligent, but also hardworking. | Not only is he intelligent, but also hardworking. | “not only”放在句首，主语前需加助动词（如is, does等）形成倒装 |
| She can not only sing, but also play the piano. | Not only can she sing, but also play the piano. | 助动词can提前，构成倒装 |
| They did not only win the game, but also broke the record. | Not only did they win the game, but also break the record. | 助动词did提前，构成倒装 |
二、注意事项
1. 助动词的选择：倒装时，必须根据原句中的谓语动词选择正确的助动词。例如：
- 原句：He has not only passed the exam, but also got a scholarship.
- 倒装：Not only has he passed the exam, but also got a scholarship.
2. 保持一致的时态：倒装后的句子应与原句保持时态一致。
- 正确：Not only did she finish the work, but also she submitted it on time.
- 错误：Not only did she finish the work, but also she will submit it.
3. 避免重复使用助动词：在“not only... but also...”结构中，第二个分句通常不重复使用助动词。
- 正确：Not only is he smart, but also he is kind.
- 错误：Not only is he smart, but also is he kind.
三、常见错误对比
| 正确用法 | 错误用法 | 原因 |
| Not only does he like coffee, but also tea. | Not only he likes coffee, but also tea. | “not only”在句首时，需倒装 |

| Not only are you wrong, but also you are careless. | Not only you are wrong, but also you are careless. | “not only”在句首时需倒装 |
四、适用场景
- 正式写作：在学术论文或正式演讲中，使用倒装结构可以增强语言的正式感和逻辑性。
- 强调重点：当需要特别强调“not only”后面的内容时，使用倒装结构更加突出。
- 口语表达：虽然在口语中较少使用，但在一些特定场合（如辩论、演讲）中，倒装结构也能增加表达的力度。
五、总结
“Not only”的倒装用法是英语中一种重要的语法现象，能够增强句子的表现力和逻辑性。掌握其结构和使用规则，有助于提升语言表达的准确性和多样性。在实际运用中，应注意助动词的使用、时态的一致性以及避免重复结构，以确保语法正确、表达自然。
