1) 一般都熟知 as well as 常常用于并列多个概念（这些概念可以表现为名词、代词、形容词、副词、介词短语，甚至谓语动词，as well as 后面的一个概念通常是已知的或是作为衬托的，重点往往在前一个概念上）。

• He gave me clothes as well as food.他给了我食物还给了衣服。
• I can't carry his bags as well as my own.我拿了自己的箱子，就拿不了他的。
• It has symbolic as well as economic significance.它既有经济意义，也有象征意义。
• He designs as well as makes fashionable dresses.他既裁制时装，也设计时装。

但是，as well as 有时候的作用不在于并列概念，而是表示两者的相似。

• Women, as well as men, have a fundamental right to work.妇女和男子一样，也有参加工作的基本权利。

此时 as well as 甚至可以像 than 或 as 那样连接一个有谓语动词的不完整的从句。

• Although IQ tests were not originally intended for use in business, studies have shown that these instruments predict work performance at least as well as competency interviews do.尽管智商测验原先不是为了用于工作业务，但是一些调研结果显示，这些手段起码能够同能力面试一样预示工作业绩。

另外，as well as 究竟是表示并列还是比较，以及拿什么同什么相比或并列，要看全文。

• A new study has found that a diet of fruits, vegetables, whole grains and low-fat dairy lowers blood pressure as well as drugs.不是拿 blood pressure 与 drugs 并列，也不是拿来相比较，而是拿 a diet of... 与 drugs 相比较（一项新近的研究发现，由水果、全麦和低脂乳制品组成的食谱，可以同药物一样降低血压）。

2) 此外，由于 as well as 的原意是“同…一样好”，有时候这个原意仍然保留，就可能产生歧义，例如：

• Jennifer plays the violin as well as Sylvia.

这一句可以是“詹尼弗也同西尔维亚一样拉小提琴”，也可以是“詹尼弗拉小提琴同西尔维亚一样好”。为了避免歧义，如果意思是前者，可以改为 Both Jennifer and Sylvia play the violin，如果意思是后者，可以改为 Jennifer and Sylvia play the violin equally well.
