定语从句：定语从句是由一些关系代词或者关系副词引导的从句组成，用来修饰名词中心词。

定语的翻译要特别注意位子上的变化，即：如果是单词修饰名词就放在中心词的前面，这和汉语的词序是一样的；如果定语太长，定语就要放在中心词的后面，这时就要注意断句，重复先行词，例如：
1.I have the same problem as you concerning the learning of English
在学英语的问题上，我和你有同样的问题。
2.She has a perfect figure.
她身材不错。
3.This is indeed a most pressing problem.
这的确是一个非常棘手的问题。

7. For several hundred years, cases have been reported of children who have been reared in the wild by animals kept isolated from all social contact.
在过去的几百年中，已经有记载说，确实有被动物养大的与世隔绝的狼孩的存在。
另外，翻译成汉语时还要注意未省略关系代词和关系副词的定语从句, 翻译时所遵守的原则和上述的一样：
关系代词引导的定语从句：
8.He is the very person (whom) I’m looking for.
他正是我要找的人。
9.This is the flexible policy that our government has pursued consistently.
这就是我们政府一直追求的灵活政策。
10.Those whose families cannot afford board and expenses can be allowed to receive scholarship.

11.There are forms that occasionally occur which should not be taught to students.
有些形式是不能告诉给学生的。
关系副词引导的定语从句：
12.I took Mr. John to the village, where I had spent my carefree childhood.
我把约翰先生带到我度过无忧无虑童年的乡村。
13.I still remember the time when we studied in the same university.
我还记得我们一起上大学的日子。
具体翻译来说，定语从句的翻译可分为限制性和非限制性定语从句两种，翻译成汉语时不论是在语序方面还是重复先行词方面都有一定的讲究：
