关系词在从句中充当主语宾语,

关系词分为关系代词和关系副词,都是定语从句中的成分关系代词在定于从句中一般充当主语或者宾语关系副词在定语从句中则只作状语充当主语比如：The student who answered the question was John.回答问题的那个学生是...The student who answered the question was John.who在从句中为什么充当主语， 什么意思，讲详细点谢谢The student was John.是主句who answered the question 是定语从句，修饰student 其实定语从句就和形容词修饰名词一样，只不过形容词是一个词，放在被修饰的名词前，比如 a good student;而定语从句是一个句子，放在被修饰的词后定语从句顾名思义也一定是个句子，是个句子就要有主谓宾，这个定语从句中主语就是who，谓语是answere，宾语是the questionwhich I bought yesterday 那么这半个句子中，I是主语，which是宾语？吗在从句中做状语又是怎么回事对 关系副词作状语，例如，He came last night when I was out.这句话中的定语从句是when I was out，修饰last night 当从句中主谓宾都有的时候就用关系副词引导定语从句关系副词一般有when where why等如果你想彻底搞懂定语从句的话我想你还是买本语法书看看吧~
