1.引导名词性从句(只用whatever)：无论他做什么都是对的.正：Whatever he did was right.误：No matter what he did was right.无论他说什么似乎都有道理.正：Whatever he says sounds reasonable.误：No matter wha...名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。Whatever he did是个主语从句就是看它在整个句子中做什么句子成分。Whatever he says （主语从句）sounds reasonable.Goats eat whatever they find.（宾语从句）
