as well as和and区别
区别在于：as well as一般只连接单词或短语，连接两个并列主语时，谓语动词用就远原则；而and除了连接单词和短语之外，还可以连接两个句子构成并列句，如果连接两个并列主语，谓语动词用复数形式。
as well as用法
1、as well as常用来连接两个并列的成分，如名词、形容词、动词、介词，通常不位于句首。作“也，还”解。它强调的是前一项，后一项只是顺便提及。因此连接并列主语时，谓语动词与前一项一致；翻译时要先译后面，再译前面。而用not only ...but also...连接时，谓语动词与后一项一致。如：
Your wife as well as you is friendly to me.
不仅你而且你的妻子也对我很友好。
（＝Not only you but also your wife is friendly to me、）
Electric energy can be changed into light energy as well as into sound energy.
电能既可以被转变成声能，又可以被转变成光能。
2、as well as用来表示同级比较，指“一样好”。如：
You look as well as you did ten years ago.
你的身体看起来还和十年前一样好。
He plays the guitar as well as you.
他的吉他弹得和你一样好。
3、用作介词此时，as well as相当于besides，in addition to，意思为“除……之外”，后面通常接名词或动词，尤其是位于句首时。As well as / Besides/In addition to eating five course meals, they drank seven bottles of wine. 除了五道菜外，他们还喝了七瓶酒。
