③no matter + 疑问词只能引导让步状语从句。如： No matter what you do, you must do it well. No matter who breaks the rule, he must be punished.
例题：-------has eyes can see --------- great achievements we have made since 1978.
A, Whoever;what B, No matter who; what
但whoever可以作为引导让步状语从句的连接代词，而no matter who 不能。
则本题答案选A
翻译：不论谁，只要长着眼睛都能看得见从1978年以来我们取得的重大成就。
