6.定语从句的译法：前置法
把英语原文的定语从句翻译成带“的”的定语词组, 放置于被修饰的词之前, 将英语原文的复合句翻译成汉语的简单句, 这种方法一般用于限制性定语从句比较短的情况。
一些较短的具有描述性的非限制性定语从句也可采用前置法, 但没有限制性定语从句使用得普遍。例如:
例1.For example, one function of friendship seems to fulfill is that it supports the image we have of ourselves, and confirms the value of the attitudes we hold.
例如, 友谊的一个作用似乎是支持我们在自己心目中的形象, 并使我们持有的价值观念更加坚定。
例2.The first two must be equal for all who are being compared, if any comparison in terms of intelligence is to be made.
如果要从智力方面进行任何比较的话, 那么对所有被比较者来说, 前两个因素 必须是一样的。
例3.The first method is to give a synonym, a word that has nearly the same meaning as the word you wish to define: face for countenance, nervousness for anxiety.
第一种方法是同义词法, 即给出一个与 要释义的词在意义上几乎相同的, 如用face表示countenance, 用nervousness表示anxiety.
例4.Behaviourists, in contrast, say that difference in scores are due to the fact that blacks are often deprived of many of the educational and other environmental advantages that whites enjoy.
相反, 行为主义者认为, 成绩的差异是由于黑人常常被剥夺了白人在教育及其他外界环境方面所享有的许多有利条件而造成的。
例5.The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind; it is simply the mode by which all phenomena are reasoned about and given precise and exact explanations.
科学研究的方法不过是人类思维活动的必要表达方式, 也就是对一切现象进行 思考并给以精确而严谨解释的表达方式。
例6.A youngster who has no playmates of his age living nearby may benefit greatly from attending nursery school.
附近没有同龄伙伴和自己玩的儿童，上托儿所可以得到很多的益处。
7.关系分类
关系从句有限制性关系从句（英语：restrictive relative clause或defining relative clause）和非限制性关系从句（英语：non-restrictive relative clause）之分。限制性关系从句起限定作用，修饰特定的名词或名词短语；而非限制性关系从句只起补充说明某种信息的作用。例如：
The government which promises to cut taxes will be popular.（限制性关系从句，指任何一个减税的政府）
The government, which promises to cut taxes, will be popular. （非限制性关系从句，补充说明（现任的）政府的情况）
There were very few passengers who escaped without serious injury. （限制性关系从句，指逃出来的乘客大多受了伤）
There were very few passengers, who escaped without serious injury. （非限制性关系从句，指游客人数本来就很少，这些游客都逃了出来且没有受伤）
7.1.限制性关系从句
从语义上看，限制性关系从句主要起限定作用，修饰特定的人或事物，如果去掉限制性定语从句，整个句子表意会不完整甚至不通顺；从结构上看，限制性关系从句常紧跟先行词，并且同先行词之间一般不加逗号分隔（但不是绝对的）。
限制性关系从句的关系词包括：that, which, who, whom, whose, as, than等。
7.2.非限制性关系从句
从语义上看，非限制性关系从句主要起补充说明的作用，有时相当于一个并列分句或状语从句，可以表达原因、目的、结果、条件、让步等意义。例如：
Dr Lee, who had read through the instructions carefully before doing his experiments, did not obtain satisfactory results. （非限制性关系从句表示让步的意义，相当于though Dr Lee had read through the instructions...）
非限制性定语从句的关系词包括：which, who, whom, whose, as等，另外that在非限制性关系从句中并非绝对不可使用。
