Question

The old tower must be saved,__the cost.A.however B.whatever C.whichever D.wherever
为什么不选A

Answer 1

答案：B.
翻译：无论代价是什么/费用要多少,这座古老的塔楼都必须被挽救下来.
解释：
1. whatever the cost = whatever the cost is = (no matter what) the cost is = no mater (what the cost is) 无论/不管代价是什么；无论/不管什么代价；无论/不管费用是多少（cost类似于price,用what提问）
此类从句中省略is的用法为非正式用语.
whatever引导一个让步状语从句,其中的whatever = no matter what,且what在从句中充当is的表语,即the cost is what.
2. 如果用however,则变成了however the cost = however the cost is = (no matter how) the cost is = no matter (how the cost is)
此时how充当从句的表语,how the cost is翻译成“代价/费用是怎样/如何”,则句意明显不通.
