完整版非限制性定语从句练习

在英语语法中，非限制性定语从句是一种非常重要的句式结构，它能够为句子增添更多的信息而不影响主句的基本含义。为了帮助大家更好地掌握这一知识点，我们特意准备了这份完整的练习题集。

首先，让我们回顾一下什么是非限制性定语从句。简单来说，非限制性定语从句是对先行词进行补充说明的成分，通常用逗号与其他部分隔开。例如，在句子“Tom, who is my best friend, always helps me with my homework.”中，“who is my best friend”就是一个非限制性定语从句，它对“Tom”进行了额外的描述。

接下来，我们来看一些具体的练习题：

1. The book ________, which was published last year, has been very popular among students.

A) it B) that C) which D) what

2. Mary, ________ works as an engineer, recently won an award for her innovative design.

5. The project, ________ took three years to complete, finally received recognition from the industry.

请尝试解答这些问题，并检查答案是否正确。通过这样的练习，您可以更熟练地识别和使用非限制性定语从句。

此外，值得注意的是，在非限制性定语从句中，关系代词“which”和“whom”经常被用来引导从句。同时，逗号的使用也非常重要，因为它决定了该从句是否为非限制性。
