选择题
_______in the ocean, it becomes powerless once it is on the beach.
A．However a whale is powerful
B．However powerful a whale is
C．Whatever a powerful whale is
D．Whatever powerful a whale is
答案
答案：B
考查让步状语从句。However修饰形容词或副词，Whatever修饰名词，排除A,D；且根据句意，应是不管鲸鱼在海里怎样强大，一旦到了海滩上它就变得没有力量了。However无论怎样，Whatever无论什么。所以选B。
