Revising useful structures

1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。

2．先行词：被定语从句修饰的词叫先行词。

3．关系词：引导定语从句的词叫关系词。

关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有when, where, why等。

关系词通常有下列三个作用：A、引导定语从句；B、代替先行词；C、在定语从句中担当一个成分。

定语从句｛限制性定语从句(restrictive)

非限制性定语从句( non-restrictive）

The teacher told me that Tom was the only person that I could depend on.

老师告诉我说汤姆是我唯一的可以依靠的人。

His mother, who loves him very much,

is strict with him.

他妈妈十分地爱他，对他要求很严格。

1. 限制性定语从句和非限制性定语从句:

限制性定语从句:所谓限制性定语从句就是先行词在意义上不可缺少的定语,如果去掉, 主句就会失去意义或意义不完整。这种从句和先行词的关系十分密切,写时不用逗号和主句分开。

e. g. I was the only person in my office who was invited. 我是我们办公室唯一被邀请的人。 (如果把从句部分去掉, 整个句子的含义就变了)

非限制性定语从句:非限制性定语从句和主句的关系并不十分密切,只是对先行词做些附加说明,如果去掉,主句的意思仍然清楚。这种从句和主句之间往往用逗号隔开。在讲话时语调上须停顿。一般不用that引导。

1) His dog, which was now very old, became ill and died.

他的狗当时很老了, 生病后就死了。(去掉从句, 主句的意义仍然完整:他的狗生病死了。)

2) Yesterday I met Li Lei, who seemed to be very busy.

昨天我碰上李雷了,他好象很忙。 (去掉从句, 意义仍然完整:昨天我碰上李雷

2. 非限制性定语从句中的一些问题：

a. 非限制性定语从句中, 指物时, 用which而不用that。

1) Football, which is a very interesting game, is played all over the world.
