（一）定語從句的結(jié)構(gòu)：在復(fù)合句中，修飾某個(gè)名詞或代詞的句子（做這個(gè)名詞或代詞的定語）叫定語從句，定語從句一般放在被修飾的名詞或代詞后面，被修飾的名詞或代詞叫做定語從句的先行詞，它與定語從句之間要有一個(gè)詞連接，這個(gè)詞指代先行詞的內(nèi)容叫做關(guān)系詞（關(guān)系代詞或關(guān)系副詞：that, which, who, whose, when, where, why）。先行詞在定語從句中充當(dāng)主語，賓語，時(shí)間，地點(diǎn)，原因狀語。
結(jié)構(gòu)：先行詞+關(guān)系詞+定語從句。
1. There she saw a wall of water that was quickly advancing towards her.
2. In Japan, someone who sees another person making the gesture will think it means money.
3. A theme park is a collection of rides, exhibitions or other attractions that are based on a common theme.

5. Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie.
6. Oprah Winfrey is a black woman whose rise to fame is an inspiring story.
（二）定語從句分為限定性定語從句和非限定性定語從句：
限定性定語從句：從句對(duì)先行詞進(jìn)行必要的描述或說明，缺少它，則句義顯得不完整，從句與先行詞緊密相連。
非限定性定語從句：對(duì)先行詞進(jìn)行補(bǔ)充說明，解釋，它與先行詞之間有逗號(hào)隔開。
1. Before she could move, she heard a loud noise, which grew to a terrible roar.

3. Flora, whose beautiful hair and dress were all cold and wet, started crying.
4. Their talk includes rhythm and rhyming words as well as tongue twisters, which often make the audience applaud.
（三）關(guān)系詞前面可以根據(jù)定語從句的內(nèi)容加上一些介詞，這些關(guān)系詞在介詞后面常用which 或whom.
1. There was a man with whom I would have to work together and finally the manager of the company.
2. Many people who saw the film were afraid to swim in the sea when they remembered the scenes in which people were eaten by the shark.
