as well as是用就远原则。当用作主语的成分后面跟有由but，except，besides，including，like，along with等引出的短语时，谓语动词习惯上要与这些结构前面的主语保持一致(即与比较远的那个主语保持一致,简称“就远原则”。
as well as简介
1、在传统用法中，as well as并不等同于and。我们知道，在not only A but also B的结构中，语义上侧重B，而在A as well as B结构中，语义上侧重A，所以，一般翻译成“不仅B，而且A；既B，又/也A”。例：
In greenhouses,computers control the watering of the plants as well as the light and the temperature.在温室里，计算机既控制光照和温度，也控制作物的灌溉。
She is clever as well as beautiful.她不仅漂亮，而且聪明。（她既聪明又漂亮。）
2、在现代英语用法中，A as well as B可以用来表示A和B同等重要，即等同于and。例：
You helped him as well as me.你帮助了他和我。
She is clever as well as beautiful.她既聪明又漂亮。
