【notonlybutalso用法总结】在英语学习中，“not only... but also...”是一个非常常见且实用的句型结构，用于强调两个并列的事物或观点。它不仅可以增强句子的逻辑性，还能使表达更加生动和有层次感。本文将对“not only... but also...”的用法进行系统性的总结，帮助读者更好地掌握这一语法结构。
一、“not only... but also...”的基本结构
“not only... but also...”是表示“不仅……而且……”的并列连词结构，通常用来连接两个并列的成分，如名词、代词、形容词、副词、动词短语、从句等。
基本结构：
Not only + A, but also + B.
其中，A 和 B 是并列的成分，可以是主语、谓语、宾语、状语等。
例如：
- Not only is he a teacher, but he is also a writer.（他不仅是一名老师，还是一位作家。）
- She not only sings beautifully, but also dances very well.（她不仅唱歌好听，跳舞也很棒。）
二、使用注意事项
1. 并列成分要一致
“not only”和“but also”后面所接的成分在语法上应保持一致，否则会破坏句子的平衡。
- 正确：He not only speaks English, but also writes it.（他不仅说英语，还会写英语。）
- 错误：He not only speaks English, but also to write it.（错误在于“to write”与“speaks”不平行）
2. 倒装结构的使用
当“not only”位于句首时，句子需要使用倒装结构，即把助动词或情态动词提前到主语之前。
- 正确：Not only did he finish the work, but also he did it perfectly.（他不仅完成了工作，而且做得非常完美。）
- 错误：Not only he finished the work, but also he did it perfectly.（错误在于没有倒装）
3. 强调重点
“not only... but also...”常用于强调后半部分的内容，即“but also”后面的部分更为重要。
- 例句：She is not only beautiful, but also very kind.（她不仅漂亮，而且非常善良。）
- 这里强调的是“very kind”，而不是“beautiful”。
三、常见的搭配形式
1. not only + 名词 / 代词 / 动名词，but also + 名词 / 代词 / 动名词
- He not only likes music, but also plays the piano.
- They not only studied hard, but also passed the exam.
2. not only + 形容词，but also + 形容词

- She is not only smart, but also hardworking.
3. not only + 副词，but also + 副词

4. not only + 动词原形，but also + 动词原形

5. not only + 从句，but also + 从句
