“not only...but also” 是英语中常用的并列连词短语，用于连接两个对等成分（如词、短语、从句或句子），强调两者均存在或成立，其核心用法和注意事项如下：

一、基本结构

Not only + 成分A + but also + 成分B

● 成分A和B 需保持词性或结构一致（如名词+名词、动词+动词、从句+从句等）。

● but also 可简化为 but（尤其在口语中），但正式写作中建议保留完整形式。

示例：

● She not only speaks English but also French.（动词+动词）

● He is not only a teacher but also a writer.（名词+名词）

● Not only did he arrive late, but he also forgot his notes.（从句+从句）

二、语法规则

1. 主谓一致

● 当连接两个主语时，谓语动词与靠近它的主语保持一致（就近原则）。
示例：

● Not only the students but also the teacher was excited.（谓语与“the teacher”一致）

● Not only the teacher but also the students were excited.（谓语与“the students”一致）

2. 倒装句（部分倒装）

● 若 not only 位于句首，其后句子需用部分倒装（助动词/be动词/情态动词提前）。
示例：

● Not only does she sing well, but she also dances beautifully.（正常语序：She not only sings well...）

● Not only have I finished my homework, but I've also helped my sister.（正常语序：I have not only finished...）

2. 否定转移

● “not only...but also” 本身不表示否定，但若需表达否定意义，否定词通常放在第一个部分。
示例：

● He not only didn't apologize but also left angrily.（更自然的说法，而非 He didn't not only apologize...）

三、常见搭配与扩展

1. 连接形容词/副词

● 强调两者程度均高。
示例：

● The movie was not only entertaining but also thought-provoking.（形容词+形容词）

● She runs not only fast but also gracefully.（副词+副词）

2. 连接从句

● 用于复合句中，连接两个并列的子句。
示例：

● Not only will they win the game, but they'll also break the record.（将来时倒装）

● Not only had she studied hard, but she'd also volunteered extensively.（过去完成时倒装）

3. 替代表达

● 口语中可用 both...and... 或 as well as，但后者不强调并列重要性。
对比：

● She is both intelligent and kind.（中性并列）

● She is intelligent as well as kind.（侧重“intelligent”，“kind”为附加信息）

● She is not only intelligent but also kind.（强调两者同等重要）

四、易错点

1. 成分不一致

● ❌ He not only plays guitar but also sings well.（“plays guitar”与“sings well”结构不对等）

● ✅ He not only plays the guitar but also sings well.（动词短语+动词短语）

2. 遗漏“also”

●❌ She not only speaks English but French.

●✅ She not only speaks English but also French.

3. 倒装错误

●❌ Not only she is late but also forgot her keys.

●✅ Not only is she late but also she forgot her keys.（或更简洁：Not only is she late but also forgot her keys.，但严格语法需重复主语）

五、实际应用场景

1. 学术写作：强调研究的双重价值。

● The study not only provides new insights but also suggests practical applications.

2. 日常对话：纠正误解或补充信息。

● A: Did he just cook dinner? B: Not only did he cook, but he also cleaned the kitchen!

3. 演讲/辩论：增强说服力。

● This policy will not only boost the economy but also improve social equity.
