8、1）as 引导限制性定语从句时，主要用在固定搭配 such. . .as, the same . . . as 中。 He is not the same man as he was. 他和以前不一样了。 （2） as 引导非限制性定语从句时，指代主句的内容，在从句中作主语或宾语，常译为“正 如” 。 Smoking is harmful to ones health, as is known to us all. 众所周知，吸烟有害健康。 （3）as 引导的非限制性定语从句可置于主句前。 As I have pointed out, it is important to include ve

10、d she spoke well. 她很喜欢讲法语，而且讲得确实很好。 （2）当先行词是专有名词或被物主代词、指示代词修饰时，其后的定语从句通常是非限制 性定语从句。 They went to London, where they lived for six months. 他们去了伦敦，在那儿住了六个月。 （3）非限制性定语从句可以补充说明整个主句。 In the presence of so many people he was a little tense, which was understandable. 在那么多人面前他有点紧张，这是可以理解的。 （4）非限制性定语从句表原因时，不

12、 我昨天晚上读了一篇文章，它非常有趣。 （2）作用不同 限制性定语从句可以修饰名词或代词，与先行词关系密切，若缺少，句意则不完整。非限制 性定语从句修饰名词或代词，也可以修饰整个句子，对先行词仅起补充说明作用，若缺少， 句意仍相对完整。 Do you remember the man who taught us English? 你记得教我们英语的那个人吗？ She and her family bicycle to work, which helps them keep fit. 她和家人都骑车去上班，这有助于他们保持健康。 可通过以下两个例句对比理解两者的区别： His brother w

14、个人。 He is a warm-hearted man, who lives next to me. 他是个热心肠的人，住在我的隔壁。 （4）关系词不同 关系代词 that 不能引导非限制性定语从句。在限制性定语从句中，关系代词作宾语时可以 省略；在非限制性定语从句中，所有关系词都不可省略。 Mr. White, whom you met yesterday, is one of my old friends. 你昨天遇到的怀特先生是我的一个老朋友。 (非限制性定语从句，whom 在从句中作宾语， 不能省略） 五、特殊结构“名词代词of + which/whom” There are 30

15、chairs in the hall, most of which are new. 大厅里有三十把椅子，绝大部分是新的。 六、关系代词、人称代词、指示代词的选择 关键是判断句子结构： 非限制性定语从句一选关系代词 并列句一选人称代词或指示代词 He came late again and this made his boss angry. 他又迟到了，这使他的老板很生气。 This is my smart phone and it was bought yesterday. 这是我昨天买的智能手机。 I met Professor Xu, who told me the result of
