这个连词：not only...but.as well怎么用?

not only…but also/as well… 不仅……而且.
其实不存在not only but as well的结构,是not only but also,省略了also,然后在句末加上as well来加强语气.as well可以省略.
说明：
若连接两个成分作主语,其谓语通常与靠近的主语保持一致；
修饰主语一类词时,be动词在not only后；
修饰表语一类词时,be动词在not only前；
as well经常放在句尾.
eg;
Not only you but I am student as well.
I am not only a student but a worker as well.
Not only did he speak more correctly,but he spoke more easily.

用在句子开头

not only...but ( also )...是并列连词，用来连接并列成分，与 and 相似，只不过比 and 语气强。
as well 意思是也与 too 同义，常用于口语。

主语+not only +动词... +but also +动词... as well

例句：It contained not only the words to songs but some of the music as well.
