先行词 关系词
从句
which、that 是关系代词，它在从句中代替先行词the building,
同时担任从句中的主语，也起连词的作用，把两个简单句连接 起来。
❖ 关系代词的使用取决于先行词，它们的关系非常密切，因为关系代词在
定语从句中代替主句中的先行词，所以它在一般情况下都跟在先行词之后， 而且它的 人称、数必须和先行词一致。
He knew the teacher (that) we met yesterday. 4.whose 是代词的所有格形式, 它既可以代人也可以代物。 I saw a woman . Her bag was stolen .
I saw a woman whose bag was stolen. Please show me the book . Its cover is red.

• 2）“先行词”的意义决定“关系词”的选择“关 系词”的选择往往是由“先行词”自身表达的意 义，以及它在从句中的语法功能而决定的。例如：
• Some people who are successful language learners often fail in other fields. 有些在语言学习上很有成就的人,在其他领域常常 一无所成。
Water whose boiling point is at 100 degree Centigrade has no color, no flavor. 沸点在摄氏100度的水无色、无味。
2021
关系代词which: 用于代替"表示事物意义"的先行词， 在从句中作主语、宾语。例如： Views which are entirely new or foreign may also be hard to accept. (做主语) 那些全新的或是来自国外的观点或许也很难被接 受。 I've got a novel which you may like to read. 我有一本你或许想看的小说。(做动词read的宾语)
2021
• （本句中的关系词where = 先行词（in） situations 。如果把这个复合句拆成两个分 句，那就是：
• They often become easily frightened or feel uneasy in situations.
• people normally would not be afraid in situations. 由此可以看出，"先行词"与"关系 词"之间实质上是互等、互换的关系）。
• In our class, we have some students whose families are not in Wuhan. 我们班上有些家不在武汉市的同学。
2021
• There are many sounds which have a meaning and yet are not words.
二：非限制性定语从句 定语从句前有逗号分隔，主要起补充说明作用，
如： Mr. Brown has a son, who joined the army 3 years ago.
2021
需要了解的概念
先行词： 定语从句所修饰的词称为先行词 通常是由名词或代词充当 They are the boys who you like to play with. Friends are those who make you smile, always share your happiness and sorrows.
2021
关系代词that： 既用于代替“表示人的意义” 的先行词，也用于代替“表示事物意义” 的先行词；在从句中既可以作主语，也可 以作谓语动词的宾语，但是不能作介词的 宾语。
定语从句
2021定语从句的定义源自• 首先我们先了解定语的概念

先行词与关系词的联系
• 1）"先行词"与"关系词"的内在联系"先行词"与"关 系词"之间实质上是互等、互换的关系。也就是说， 关系词的作用就是将先行词所表达意义"代到"从 句中来起作用。例如： They often become easily frightened or feel uneasy in situations （先行词）where (关系 词)people normally would not be afraid . 他们常在人们一般不会感到害怕的情况下却很容 易感到恐惧或是感到不自在。

• 关系代词whose ：用于代替"表示人或物意义"的 先行词，在从句中作定语，往往与它所修饰的名 词一起构成一个名词短语在从句中担当成分。 Whose常表达"某人的、某物的"之意。例如： Do you know the name of that girl whose brother is your roommate? 你知道她的哥哥与你同寝室的那位女孩的名字吗？
• 2）“先行词”的意义决定“关系词”的选择“关 系词”的选择往往是由“先行词”自身表达的意 义，以及它在从句中的语法功能而决定的。例如：
• Some people who are successful language learners often fail in other fields. 有些在语言学习上很有成就的人,在其他领域常常 一无所成。
Water whose boiling point is at 100 degree Centigrade has no color, no flavor. 沸点在摄氏100度的水无色、无味。

关系代词which: 用于代替"表示事物意义"的先行词， 在从句中作主语、宾语。例如： Views which are entirely new or foreign may also be hard to accept. (做主语) 那些全新的或是来自国外的观点或许也很难被接 受。 I've got a novel which you may like to read. 我有一本你或许想看的小说。(做动词read的宾语)

• （本句中的关系词where = 先行词（in） situations 。如果把这个复合句拆成两个分 句，那就是：
• They often become easily frightened or feel uneasy in situations.
• people normally would not be afraid in situations. 由此可以看出，"先行词"与"关系 词"之间实质上是互等、互换的关系）。
• In our class, we have some students whose families are not in Wuhan. 我们班上有些家不在武汉市的同学。
