what与how引导定语从句例句（what和how从句的用法区别）

1. What he said yesterday made me happy. (what引导定语从句，修饰先行词是he said)
2. How she managed to finish the project in one day amazed me. (how引导定语从句，修饰先行词是she managed)

what与how都可以用来引导定语从句。
其中，what通常引导一般性的定语从句，修饰名词或代词，如“I don't know what you mean."（我不知道你的意思是什么）；而how通常引导特殊性的定语从句，修饰动词或形容词，如“I am amazed at how well he can speak Chinese.”（他中文讲得很好，我很惊讶）。
