These wild flowers are so specia

These wild flowers are so special that I would do_____ I can to save them.
A、whatever
B、that
C、which
D、whichever
【正确答案】：A
【题目解析】：考查名词性的引导词。题意是：这些野花太特别了，我想尽我所能拯救它们。句中do后是一个宾语从句，I can 后承前省略了谓语动词do, to save them 是目的状语。可以看出宾语从句I can do 不完整，缺少宾语成分，所以引导词要用关系代词what 或whatever.人们常把 do what/whatever sb can to do sth 当承一个句式，意为“尽力去做某事”。故答案为A.
