在英语中,“not only...but also...”是一个非常常见的结构,用来连接两个并列成分,表达递进关系或强调某种逻辑上的关联。它既可以用于句子内部,也可以用于句与句之间的衔接。正确使用这个结构不仅能提升语言的表达能力,还能让文章更加流畅自然。
一、“not only...but also...”的基本功能
“Not only...but also...”的核心作用是将两个事物进行对比或者强调它们之间的联系。通常情况下,前半部分表示否定的部分,后半部分则为肯定的部分,两者形成一种递进或补充的关系。例如:
- 语法功能:连接主语、谓语动词、宾语、状语等。
- 语义关系:表示递进(moreover)、转折(on the other hand)或补充(in addition)。
二、“not only...but also...”的具体应用
1. 连接主语
当“not only...but also...”连接两个主语时,谓语动词的形式需要根据“就近原则”来确定。即谓语动词的形式取决于“but also”后面的主语。
例句:
- Not only Tom but also his friends are interested in playing basketball.
- Not only she but also I am going to attend the meeting.
2. 连接谓语动词
当“not only...but also...”连接两个谓语动词时,只需要保留一个助动词或情态动词,另一个省略即可。
例句:
- She not only speaks fluent English but also writes it well.
- He not only enjoys reading novels but also likes writing short stories.
3. 连接宾语
当“not only...but also...”连接两个宾语时,可以直接使用该结构,无需改变句子结构。
例句:
- The teacher gave us not only homework but also some useful advice.
- We bought not only books but also stationery for our new term.
4. 连接状语
当“not only...but also...”连接两个状语时,可以用来表达时间、地点、方式等方面的递进关系。
例句:
- Not only did he work hard, but also he was always kind to others.
- She arrived not only early but also prepared everything in advance.
三、“not only...but also...”的注意事项
1. 避免重复:如果“not only...but also...”连接的是相同的成分(如主语、谓语),那么为了避免冗余,可以省略前面的一部分。
例句:
- Not only he but also his brother is talented in music.
(省略为:He is talented in music, and so is his brother.)
2. 保持一致性:无论是连接什么成分,“not only...but also...”前后的内容应尽量保持一致,以确保语义清晰。
3. 注意语气:虽然“not only...but also...”常用于正式场合,但在口语中也十分常见。因此,在写作或演讲时要根据具体情境选择合适的语气。
四、实例分析
通过以下例子进一步理解“not only...but also...”的实际运用:
