和在一起写的如whichever等与分开写的如No matter which等既可以引导名词性从句,也可以引导让步状语从句,而引导名词性从句时只能用whichever等这种和在一起写的连词了.如:
Whichever breaks laws will be punished .=No matter which breaks laws will be punished.无论哪一个犯了法都要受到惩罚..一个先行词加一个关系代词.你用这种方法替换一下,能讲得通的就是主语从句做主语了.
No matter which breaks laws,we will punish him.无论哪一个犯了法,我们都要惩罚他.前面是一个让步状语从句.
