你好，很高兴为你解答:
（1）
as well as常用来连接两个并列的成分,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；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.
追问后面不够清楚
