高中英語定語從句
英語定語從句在高中是重點知識之一，以下是小編分享的高中英語定語從句，一起來閲讀吧！
一、定語從句之結構
定語從句用來充當句中定語的主謂結構；它主要用於修飾句子中的名詞、代詞。
定語從句的位置常常是緊跟在被修飾的名詞、代詞的後面。在被修飾的名詞、代詞與定語從句之間往往有一個關係詞將其前後兩部分聯繫成一個整體，或是構成一個名詞短語；或是構成一個代詞短語。
從結構上説，關係詞與從句是一個整體。
排除句子的其他各部分，這種帶有定語從句的名詞短語或是代詞短語的構成可演示如下：
1）Three signs that indicate a person is suffering from a panic attack rather than a heart attack.三種意味着一個人是患有驚恐症而不是心臟病的跡象。
在這個帶有定語從句的名詞短語中：signs是：被修飾的名詞； that是：關係詞；that indicate a person is suffering from a panic attack rather than a heart attack是定語從句
2）Those who drink a lot. 那些大量飲酒的人。
在這個帶有定語從句的代詞短語中：those是：被修飾的`名詞； who是：關係詞;
定語從句通過上面的演示,我們可以歸納出定語從句在句子中的位置、結構如下：被修飾的名詞 / 代詞 + 關係詞 + 句子 (其中，"被修飾的名詞/代詞"在語法叫作"先行詞".)
二、定語從句講解
（一）定語從句的結構：在複合句中，修飾某個名詞或代詞的句子（做這個名詞或代詞的定語）叫定語從句，定語從句一般放在被修飾的名詞或代詞後面，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詞連接，這個詞指代先行詞的內容叫做關係詞（關係代詞或關係副詞：that, which, who, whose, when, where, why）。先行詞在定語從句中充當主語，賓語，時間，地點，原因狀語。
結構：先行詞+關係詞+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.
4. The park has a conservation center that helps protect marine animals and their habitats in the rivers and coastal waters of Asia.
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：從句對先行詞進行必要的描述或説明，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：對先行詞進行補充説明，解釋，它與先行詞之間有逗號隔開。
1. Before she could move, she heard a loud noise, whichgrew to a terrible roar.
2. Tree after tree went down, cut down by the water, which must have been three meters deep.
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）關係詞前面可以根據定語從句的內容加上一些介詞，這些關係詞在介詞後面常用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.
