_____helps you should be thanked,anyway A.No matter who B.Nomatter whom c.Whoever D.Who

_____helps you should be thanked,anyway A.No matter who B.Nomatter whom c.Whoever D.Who

whoever引导名词性从句,如主语从句,宾语从句.
此处应该是whoever.
有一个技巧,因为whoever在引导状语从句的时候与no matter who可以互换,所以有whoever和no matter who同时出现的时候,选whoever.

选 C

选D
