「as well as」应该是英文学术论文写作时最常被误用的表达之一。

今天就来八一八 这个 as well as 吧！

在所有的错误使中，最常见的就是将「as well as」和「and」作为同样的意思来使用，是不是大多数人觉得as well as看起来比and更书面，更高bigger，所以就任意替换了。实际上，这两者确实有着相近的意思，但是二者之间从更深层的含义上以及语法上都有明显的区别。

说二者具有相近的意思，and常作为连词，as well as在这里是做介词，更确切的说，应该是和「in addition to」有着相近的意思。因此表达「A as well as B」的话，并不是传达「A and B」这样「A与B具有等同地位」的AB「对等性」的信息，而是「除了B以外A也具有」、「和B一样A也」、「不仅B。。。A也。。。」，它表示A与B的关系是「不对等性」的。

[注1] 「as well as」这一语法有 两种用法，一种如上所述，另一种「as [副词・形容词] as」这样作为更一般的表达形式，也就是「与～具有相同程度的」这样的用法举例，如：「in as satisfactory a way as」、「with equal skill as」、「with equal thoroughness as」、「as carefully as」、「to the same degree/extent as」、「as much as」等语法表达具有相同的意思。这一用法的话，错误使用较少，在这里就不做赘述了。
