问
Whichever they may differ widely in function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm. (TOEFL)
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:
-
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。
-
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。
-
The painting looks wrong however you look at it. (AEG) 这张画不论怎么看都显得不对劲。
