短语as well as是一个经常误用的表达之一1 。在多数情况下，误用源于把as well as当做和and用法一样的错误认知。尽管这两种表达有相似的含义，但它们有着重要的语法和语义区别。当把as well as用作介词与and含义相似时，它的同义词是in addition to。因此对照A和B，“形式A as well as 形式B”的表达意义类似于这其中之一：不仅B，而且A；类似于B，A也是；当然是B，但也是A；除B外A也是。因此它形容的是A和B的不对称情况。
以下我们举例说明as well as最常误用的情况。
- Here, we investigate all three of these methods, and we find that the first method as well as the second method are applicable to systems of long homopolymers.
- This type of condition is seen in the cases of blunt trauma as well as shaking trauma.
- This theory has been successfully applied to the study of the demographic transition, urbanization and specialization, as well as increased standard of living.
- Here, we consider the five points raised by Miller in his treatment of parliamentary republics. However, we study these in a broader context that includes parliamentary republics as well as presidential republics.
- Experiments were performed for the cases of both increasing temperature as well as decreasing temperature.
上述句子可以用不同的方式纠正。以下应该是最适当的：
- Here, we investigate all three of these methods, and we find that the first method and the second method are applicable to systems of long homopolymers.

(2’) This type of condition is seen in the case of blunt trauma, as well as shaking trauma. - This theory has been successfully applied to the study of the demographic transition, urbanization and specialization, and increased standard of living.
(3’) This theory has been successfully applied to the study of the demographic transition and urbanization and specialization, in addition to that of increased standard of living. - Here, we consider the five points raised by Miller in his treatment of parliamentary republics. However, we study these in a broader context that includes presidential republics as well as parliamentary republics.

1短语as well as有两个主要用法。其中之一有个一般形式的例子[as + 形容词/副词 + as], 它的同义词为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等等。但当用作此类含义时，涉及到as well as的误用会比较少见，因此我们这里没有探讨此类用法。还有几个非标准的用法我们这里也没有考虑进去。
