在英语语法中，定语从句是一种非常重要的句式结构，它能够帮助我们更清晰地表达信息，并使句子更加丰富和生动。通过定语从句的学习与实践，我们可以更好地掌握语言的灵活性与多样性。接下来，让我们通过一些练习题来巩固对定语从句的理解。

例题解析

题目1：

The book ________ you gave me yesterday is very interesting.

A. who

B. whom

C. that

D. whose

正确答案是 C. that。在这个句子中，“you gave me yesterday”是一个定语从句，用来修饰先行词“the book”。由于先行词在从句中作宾语，因此可以用关系代词“that”或省略。

题目2：

This is the man ________ lives next door.

A. which

B. who

C. what

D. whose

正确答案是 B. who。这里的先行词是“the man”，表示人，在定语从句中充当主语，所以使用关系代词“who”。

题目3：

The girl ________ hair is curly is my best friend.

A. who

B. whose

C. whom

D. that

正确答案是 B. whose。这里的关系代词“whose”表示所属关系，“hair”是“the girl”的所有格形式。
