what可以用来引导定语从句吗?比如说I don't know what he said?这句话的what 是什么 成分 I don't know what he said的同意句是什么? 请问这是什么从句,That isn't what he wants.请问what引导的是什么从句? Don't you know what I said?-( ) 请问 i don't know what you said “what”作什么成分呢 定语从句可以用What引导吗? what he said是what引导的主语从句. you know what i mean 引导的是什么从句? I don't care what he said? What 引导的主语从句,what可以做哪些成分? I don't know what he needs I don't know what you said just now is what mean 这句话有没有语法错误,
