定语从句 II

Ⅲ.Grammar points:
非限制性定语从句
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。
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.
