题目内容
1．The Internet is a wonderful discovery， of great significance to people's lives．（ ）| A． | which I think is | B． | which I think it is | ||
| C． | as I think | D． | as is I think |
分析 网络是一个伟大的发现，我认为它对人们的生活意义重大．
解答 答案：A 题干中of great significance to people's lives修饰discovery，是一个非限制性定语从句；句子I think是插入语，不影响从句结构；which在从句中作主语．故选A．
点评 定语从句是用来修饰名词的形容词性从句，相当于一个形容词．连接定语从句的引导词分为关系代词和关系副词，关系代词在从句中要作主语或宾语；关系副词在从句中作状语．这也是选择关系词的一个判断方法．
