Answer 3

其实定语从句就是相当于形容词组，修饰的是前面的名词。
例如：The student （who answered the question ）was John.
括号里的部分就是定语从句，此句修辞的是前面的 The student。 整句翻译成：回答问题的那个学生是约翰。
who 在句中是“关系代词”也就是和前面的名词是什么关系、前面的名词是人，那么“关系代词”可用who 和that等等，其实定语从句主要就考“关系代词”的用法。
This is （the book）名词（ which has been translated into many languages从句）。翻译:这就是译成多种语言的那本书。
其中那个which是“关系代词”
