【问】 they may differ widely in all cells have a membrane

and an internal， water-rich substance the cytoplasm. (TOEFL，92. 5)

我看不出whichever用在这里有什么错误。

【答】 whichever与however有一个很重要的区别，就是前者在从句中一般用作定语(后面要跟着名词)，而后者一般在从句中用作状语(修饰动词、形容词或副词)。此外，含however的从句常常用作让步状语：

1. She could not remember，however hard she tried. (EED)

不管她怎么努力去回想，她还是记不起来了。

2. However great the pitfalls may be，we must do our best to succeed. (CGEL)

不管有多大风险，我们也要做出最大的努力去获得成功。

3. The painting looks wrong however you look at it. (AEG)

这张画不论怎么看都显得不对劲。
