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。
　　
Person has pieced together the worked of hundreds of researcher around the world to produce a unique millennium technology calendar that gives the latest date when we can expect hundreds of key breakthrough and discoveries to take place.
　　
皮而森 汇集了...生产出独特的千年历，这种千年历（它）能够...
　　
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。

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。

关系副词引导的定语从句：

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。
　　
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：
　　
限制性定语从句的翻译可分为以下几方面：
　　
1．前置：
　　
这种定语从句一般比较短，翻译起来比较方便，和汉语的词序完全一样，例如：
　　
a.This is the finest weather that I have ever seen this month.
　　
这是这个月我所看到的最好的天气。
　　
b.Our two countries are neighbors whose friendship is of long standing.
　　
我们两国是友谊长存的友好邻邦。
　　
c.Teachers generally like the students who achieve high scores in tests.
　　
老师通常喜欢考试中成绩好的学生。
　　
d.他不是一个轻易服输的人
　　
He is not the one who will give up easily.

　　
以上的这些例子告诉我们，如果定语很短的话，我们可以把他象汉语一样放在中心词的前面。但是，有的时候，如果定语太长，读起来就不符和汉语的习惯，因此，往往要后置，重复先行词,这就是下面要提到的定语从句的 “后置” 问题，例如：
　　
2．后置：
　　
a. Misers are often lonely and obscure men whose wealth is revealed only after their death.
　　
吝啬鬼经常是看起来年很孤单、不为人所主意，可他们的财富只有等到他们死了以后才 暴露出来。

3．“综合性”的翻译法。
　　
综合性”的翻译就是，翻译时不需要关系词，其中的关系完全靠上下文的意思来表现出来，例如：
　　
a.This is the place where the accident occurred.
　　
这就是发生交通事故的地方。
　　
b.The person who delivered the letter to him is his neighbor.
　　
他的邻居把信交给了他。
　　
c. There is a big oak tree that stands just in front of the village.
　　
村子前面有棵大象树
　　
d.Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble.
　　
大多数病人想找人坦率、诚实地倾诉他们的苦衷。
　　
非限制性定语从句：
　　
1.前置：
　　
a. We need a chairman, in whom everyone has confidence
　　
我们需要一个人人都信赖的主席。
　　
b.The worldly well-known actor , who had been ill for two years, meet thunderstorm applause when reappeared on the stage.
　　
那个病了很多年的著名演员，一上台观众就报以雷鸣般的掌声。
　　
c. Piccaso, whose works inspired many artists, lived until he was a ripe old age.
　　
毕加索的作品曾鼓励了很多人，后来年纪很大时，作品也日趋成熟。
　　
2.后置:
　　
a.He deposits a little sum of money in the bank, by which means he hopes to deal with any potential emergency easily.
　　
我们每个月都在银行里存一些钱，这样，碰到有任何危机时，我们就可以应付了。
　　
b. A table has four legs, one of which is broken.
　　
桌子有四条腿，其中的一条腿是坏的。
　　
c. Living in the central Australian desert has its problems, of which obtaining water is not the least.

d.He decided to resign, which is the best thing he could do under the circumstances.
　　
他决定辞职，而这是他目前所能做的最好的事。
　　
e.He is late for class today, as is often the case.
　　
他今天迟到了，而这是经常的事。

　　
3.省略先行词
　　
这种句行就象前面讲的“综和性”翻译一样，直接把整个句子的意思讲出来，例如：
　　
a.The two universities signed an agreement, under which they would exchange students and scholars.
　　
这两个大学，签定了协议，决定交换学生和学者。
　　
b.He caught a young soldier coming to the farmhouse , whose face turned pale for too much loss of blood.

c. He passed the exam, which can be read from his the light on his face.
　　
我从他脸上就可以看出他已通过了考试。
　　
d. He arrived at the railway station in time , which is expected .
　　
他果然准时到了火车站。
　　
4.译成状语从句
　　
有些作定语的句子听起来却有点象状语从句，因此翻译时可以将其译成状语似的从句：
　　
a.You should take advantage of the opportunity to learn English well, which is very valuable.(原因)
　　
你应该利用这个机会好好学习英语，这太重要了。
　　
b.We examine the quality of our products, which is why they are so reliable.(原因)
　　
我们检验产品很仔细，因此产品都很可靠。
　　
c.I never believe the stories, which is appealing.(让步)
　　
我从不相信他所说的故事，即使它很动听。
　　
5. “as”引导的句子：
　　
除了以上这些例子以外，还有一些特殊的由 “as”引导的句子, 翻译时可参考“as”的比 较结构从句：
　　
a. He is not such as fool as he looks
　　
他并不象看上去的那么傻。
　　
b. They were not such questions as could easily be disposed of.
　　
这些问题可不是那么容易就能处理好的。
　　
c. It wasn’t such a good dinner as she had promised us.
　　
这顿饭可没有她向我们说的那么好。
