not only.but also在句子中的用法

如果是参加考试的话，其实它的考点很简单，就是考not only位于句首时，紧跟的句子要用部分倒装。
至于它的知识点，您可以看看：
1．连接主语：
Not only I but also Tom and Mary are fond of watching television.
不仅我，而且汤姆和玛丽都喜欢看电视。
由于not only A but also B句式的重点在B上，所以谓语动词一般要与B保持人称和数的一致。例如：
但是，1992年第6期《英语学习》问答栏主持人刘承沛教授认为B为单数时动词也可用复数，因为根据意念原则”（principle of notion）主语并列具有复数意义，故下面一句成立：“Not only she but (also) her brother like playing the piano.”
2．连接谓语动词
The Americans and the British not only speak the same language but also share a large number of social customs.英国人和美国人不但语言相同，而且有很多相同的风俗习惯。
注意not only…but also连接的动词一般不重复，这与汉语不同。如汉语说“我不仅懂英语，而且懂俄语”，英语则说“I know not only English but also Russian”，而不说“I not only know English but also know Russian”.再如：“气体不仅改变形状，而且改变体积”，英译为“A gas changes not only in shape but also in volume.”（注意介词常重复）
3．连接宾语：
The problem for the recipient was trying to guess not only who the sender was, but also what his secret feelings might be.收信人不仅要尽力猜出是谁的，还要推测寄信人内心有什么想法。
4．连接宾语补足语：
Light and bright colors make people not only happier but more active.浅色和鲜艳的颜色不但使人看了高兴，也会使人更加活泼。
5．连接表语：
Shakespeare was not only a writer but (also) an actor 莎士比亚不仅是一位剧作家，而且是一位演员。
6．连接状语：
If your friend reminds you kindly of your faults, take what he says not merely pleasantly but thank fully. 如果低你的朋友善意地指明出你的缺点，你不但要欣然接受，而且要心怀感激之情。
7．连接从句：
He didn’t let us off the hook until we had proved not only that we knew what an organism was but also that we had the fortitude to stand up for the truth. 直到我们证明了我们不仅知道什么是生物体，而且具有坚持真理的不屈不挠精神时，他这才放过我们。
8．连接定语：
Man has become master not only of the sky but also of the space. 人类不但征服了天空，而且征服了太空。
9．连接句子：
I not only heard it, but (also) I saw it. 我不仅听到、而且看到了它。 Not only…but also连接句子时, not only 可以置于句首表示强调,这时第一分句要采用倒装结构。例如：
Not only has he a first-class brain but also he is a tremendously hard worker. 他不仅有着头等聪明的脑子，而且工作很能吃苦。
Not only had the poor man been arrested but he had been sent to * as well. 这个可怜的人不仅被逮捕，而且被投进*。

不仅……而且……but also 后面经常倒装,also可省略~eg:1.not only beautiful,but also practical 既美观,又实用 2.not this merely but also; not only so but.不仅如此；不限于此.3.Yes.Not only interesting but ...
