not only…but also:【不但……而且……】用法解析
▶ 所属词性:并列连词(递进连词)
核心功能:用于连接两个并列的成分或分句,
表示递进关系,强调后者比前者更进一步,语气上突出后一部分内容。
一、连接并列成分(你给的例句)
可连接名词、动词、形容词、短语或分句,连接并列谓语时,可省略重复的主语。
▶ 1. She not only sings, but also dances.
【她不仅会唱歌,而且会跳舞。】
▶ 2. He not only studies hard, but also helps others.
【他不仅学习努力,而且乐于助人。】
二、句首倒装规则
当not only 放在句首时,后面的分句需要使用部分倒装语序,
将助动词提到主语前面, but also 后的分句保持正常语序。
▶ 1. Not only does she sing well, but also she dances beautifully.
【她不仅歌唱得好,而且舞跳得也很美。】
▶ 2. Not only has he read the book, but also he remembers every detail.
【他不仅读过这本书,而且记得每个细节。】
三、主谓一致:就近原则
当 not only…but also…连接两个主语时,
谓语动词的单复数要与离它最近的主语(即 but also 后的主语)保持一致。
▶ 1. Not only the students but also the teacher is happy.
【不仅学生们很高兴,老师也很高兴。】
▶ 2. Not only he but also his friends are coming.
【不仅他要来,他的朋友们也要来。】
▶ 核心使用禁忌与注意事项
1. 倒装规则不能错用
只有not only放在句首时才需要倒装,放在句中时无需倒装。
▶ 正确:She not only sings, but also dances.
【她不仅会唱歌,而且会跳舞。】
▶ 正确:Not only does she sing, but also she dances.
【她不仅会唱歌,而且会跳舞。】
▶ 错误:Not only she sings, but also dances. ❌
【错误:句首 not only 未倒装】
2. 就近原则必须遵守
连接两个主语时,谓语动词要和but also后的主语保持一致,不能和前面的主语保持一致。
▶ 正确:Not only he but also his friends are coming.
【不仅他要来,他的朋友们也要来。】
▶ 错误:Not only he but also his friends is coming. ❌
【错误:谓语动词与前面的主语 he 保持了一致,违反就近原则】
3. 可以省略 also,但不能省略 but
在口语和书面语中, also 可以省略,但 but 不能省略。
▶ 正确:She not only sings, but dances.
【她不仅会唱歌,而且会跳舞。】
▶ 错误:She not only sings, also dances. ❌
【错误:省略了 but 】
4. 连接的成分要保持结构对称
为了句子的平衡与通顺, not only 和 but also 连接的成分应尽量保持结构一致。
▶ 正确:He is not only kind but also helpful.
【他不仅善良,而且乐于助人。】
▶ 不推荐:He not only is kind but also helps others.
【不推荐:结构不对称,读起来不通顺】
