“not only…but also…”是英语中高频并列连词短语,核心含义是“不仅……而且……”,用于连接两个平行、递进的成分(如主语、谓语、宾语、表语、状语等),强调后者在程度、范围或重要性上的延伸。
“not only…but also…”连接的两部分需语法功能一致(如都是名词、动词、形容词等),确保句子结构对称。以下是常见场景:
此时谓语动词需遵循“就近原则”(与靠近谓语的主语保持人称/数的一致)。
例:
Not only my parents but also I am going to the party.(不仅我父母,我也去派对。)
Not only the students but also the teacher likes this book.(不仅学生,老师也喜欢这本书。)
强调动作的递进(先做A,再/还做B)。
例:
She not only sings well but also dances beautifully.(她不仅唱歌好,跳舞也很美。)
He not only finished his homework but also helped his sister with hers.(他不仅完成了自己的作业,还帮妹妹做了。)
例:
I like not only apples but also bananas.(我不仅喜欢苹果,还喜欢香蕉。)
She enjoys not only reading but also writing.(她不仅喜欢阅读,还喜欢写作。)
例:
The movie is not only interesting but also educational.(这部电影不仅有趣,还很有教育意义。)
He is not only a teacher but also a writer.(他不仅是老师,还是作家。)
例:
We traveled not only to Paris but also to London.(我们不仅去了巴黎,还去了伦敦。)
She speaks English not only fluently but also accurately.(她英语说得不仅流利,还很准确。)
当“not only”置于句首时,其后的句子需用部分倒装(将助动词/情态动词/be动词提前,实义动词位置不变),以强调“不仅……”的内容;但“but also”后的句子仍用陈述语序。
例:
Not only did he pass the exam, but also he got full marks.(他不仅通过了考试,还得了满分。)
(正常语序:He not only passed the exam... → 倒装后:Not only did he pass...)
Not only is she smart, but also she works hard.(她不仅聪明,还很努力。)
若“but also”后的成分与前面重复,可省略重复部分(保持核心词即可)。
例:
She not only plays the piano but also (plays) the violin.(她不仅弹钢琴,还拉小提琴。)
He not only likes math but also (likes) physics.(他不仅喜欢数学,还喜欢物理。)
口语中可省略“also”,简化为“not only… but…”(含义不变)。
例:He not only sings but dances.(他不仅唱歌还跳舞。)
避免误用:连接的两部分需逻辑递进,不可矛盾(如“not only happy but also sad”不符合逻辑)。
“not only…but also…”的核心是“递进并列”,关键要保证连接成分的语法对称,注意“就近原则”和“句首倒装”的特殊情况。通过例句练习(如替换不同成分),能快速掌握其用法~
