as well as的疑惑

as well as的疑惑
在星火02年专四真题作文中 看到一句话
one who does physical exercise every day tends to strengthen his respiratory system as well as building a strong immune system.
在这里,as well as 后怎么是接building?不应该是build吗?
请给予一定的语法分析
答
一般来说AS WELL AS前后是一致的,如本句就可改为one who does physical exercise every day tends to strengthen his respiratory system as well as（to） build a strong immune system.但这只是它的一种用法,as well as 在与动词连用的时候也可以连接其ing形式,这种情况就是你在作文中看到的那种.此时,你可以将as well as 理解为in addition to.要注意,连接ing的这种情况时,as well as 常放在句子的开头!
