as well as的用法总结如下：

as well as 表示又、不但…而且….

as well as后是已知信息， 因此不强调其后的内容，而强调其前的内容，翻译时先译后再译前

She is brave as well as clever. 她不但聪明，而且勇敢。（已知: 聪明; 强调：勇敢）

It is cold as well as damp today. 今天不仅潮湿，而且冷。

It is pleasant in spring as well as in autumn.不但秋天，而且春天让人感到惬意。

as well as 与主语连用时，谓语动词与其前的主语（强调的内容）保持一致：

Mary, as well as her parents, was delighted to hear the news. 玛丽和她的父母一样，很高兴听到这消息。

Jane as well as her friends is late. 和她的朋友一样，简迟到了。

注： 

as well as 更常被视为介词，其后接的动词为-ing形式

He hurt his arm, as well as breaking his leg. 他不但摔断了腿，而且还伤了胳膊。

He dances as well as playing the guitar. 他不但会弹吉他，而且会跳舞。

若前接带to动词不定式，则后接动词原形

I have to clean the floors as well as cook the food. 我不但要煮菜，还要打扫地板。

He expects me to close the deal as well as make friends with clients. 他不仅指望我与客户做朋友，而且期望我能做成这笔生意。
