Section Ⅱ　Using language [对应学生用书P9] 非限制性定语从句只是对先行词进行补充说明，主从句的关系并不十分密切，如果省略非限制性定语从句，主句的意思仍然完整清楚。非限制性定语从句和主句之间往往用逗号隔开。 一、非限制性定语从句的关系词 1．关系代词的选择 关系代词 所指 所作成分 who 指人 主语 whom 指人 宾语(不能省略，不能用who替代) which 指代整个主句或主句的一部分 主语/宾语 whose 指人或指物 定语 as 指代整个主句或主句的一部分 主语/宾语 ◆Mr.Zhang，who came to see me yesterday，is an old friend of my father. 张先生是我父亲的一位老朋友，他昨天来看我了。 ◆Peter，whom you met in London，is now back in Paris. 彼得现在回巴黎了，你在伦敦见过他。 ◆Mr.Zhu，whose daughter was admitted to Tsinghua University last year，retired yesterday. 朱老师昨天退休了，他女儿去年被清华大学录取了。 ◆Tom studies hard and is ready to help others，which is what his parents expect. 汤姆学习努力且乐于助人，这正是他父母所期望的。 ◆More and more people in the world，as we see，have come to realize the significance of pollution control. 正如我们所见，世界上越来越多的人已经意识到控制污染的重要性。 [温馨提示]　(1)非限制性定语从句不能用关系代词that引导。 (2)as引导非限制性定语从句时常用于以下结构：as we all know/as is known to all众所周知；as you can see如你所见；as is expected正如预料的那样；as has been said above如上所述；as is often the case这是常见的情况。 (3)as与which引导非限制性定语从句的区别 关系代词 指代 意义 从句位置 as 引导的从句只能指代整个主句的内容 正如；像 可位于句首、句中或句末 which 引导的从句既可指代整个主句的内容，又可指代主句的一部分 这一点；这/那 一般位于主句之后 2．关系副词的选择 关系副词 所指 所作成分 when 时间名词 时间状语 where 地点名词或抽象地点名词 地点状语 ◆We will put off the outing until next week，when we won't be so busy. 我们将把郊游推迟到下个星期，那时我们就不会那么忙了。 ◆I climbed up to the top of the hill with my friend，where we enjoyed a splendid view of the lake. 我和朋友一起登上了山顶，在山顶上我们欣赏到了湖光美景。 [温馨提示]　关系副词why不能引导非限制性定语从句，但可用for which代替why来引导。 ◆None of us accepted the reason he explained，for which he was absent. 我们没有一个人接受他所解释的缺席的理由。 [即时演练1]——用适当的关系词填空 (1)(2025·全国二卷)Yet now，I live in the countryside of Zhejiang，China with my Chinese husband and his family，where bamboo and tea bushes(灌木)grow wild in the mountains，chickens are always free-range，and central heating doesn't exist.
