高中定語從句教學

　　對比法導入：

black bag is beautiful.

2. The bag which you bought yesterday is beautiful. 不同：第一個形容詞作定語，第二個句子作定語。

我有一隻蘋果。那隻蘋果是紅色的。

我有一隻紅色的蘋果。(除了用I have a red apple. 還可以用一個定語從句來表達) I have an apple. The apple is red.

I have an apple that / which is red.

I like some friends. Some friend like sports. (用定語從句合併成為一個複合句)

The magazine is mine. He has taken it away. (同上) The students will not pass the exam. They don’t study hard.

The play was wonderful. We saw it last night.

　　如何合併兩個簡單句成為一個定語從句?

找錯誤：(結論：先行詞不能出現在定語從句中)

1. The boy whom/that we saw the boy yesterday is my brother.

2. The car which /that my uncle had just bought it was destroyed in the earthquake.

定語從句:在複合句中作定語，修飾名詞或代詞的從句。這種從句由關係代詞或關係副詞引導，並作句子成分。

關係代詞：引導定語從句的代詞，在句子中充當名詞作用，有： Who, whom, which, that, whose, as

關係副詞：引導定語從句的副詞，在句子中充當副詞的作用。 有：when, where和why

限制性定語從句(識別性從句)：對先行詞起修飾限制作用，如果去掉，主句意思就不完整明確，與主句的關係十分密切。

Do you know the woman who/that lives next door?

非限制性定語從句(補充性從句)：對先行詞作附加的説明，與主句的關係不十分密切，較鬆散。從句和主句之間用逗號分開, 相當於一個插入語, 不能用that和why(可以用for+which)引導，關係代詞做賓語時也不能省略。 night, I saw a very good film, which was about the Long March.討論：討論關係代詞與關係副詞在以下定語從句中的不同作用。 1. Do you know the woman who/that lives next door? 2. The woman whom I want to visit was not in the company. 3. What happened to the money that /which you are looking for?

4. Please pass me the magazine whose cover is yellow.

5. I shall never forget the day when I bought I bought my computer.

6. People would like to live in the country where there is plenty of sunshine and fresh air.

7. The reason why I am phoning you is to invite you to my birthday party.

考點一:如何判定用關係代詞還是用關係副詞

方法一、找出定語從句中是否主語和賓語都齊全。如齊全用關係副詞。 用什麼關係副詞看先行詞。 you made such a great success. The reason ___ she gave was not true.

方法2、確定定語從句的`謂語動詞是不是及物動詞，如是，用關係代詞，如不是，用關係副詞。(常用常考) 方法3、如定語從句中謂語結構是被動結構，有主語，則用關係副詞。 October 1st is the day ________ new China was founded. 考點二：that/which 代物時用that的情況

　　看例子，找規律：

1)English is the most difficult subject that you will learn during these years.

1.先行詞是最高級形容詞或它的前面有最高級形容詞修飾時。

2) This is the last place (that) I want to visit.

2.先行詞是序數詞，或它前面有一個序數詞時。

3)You should hand in all that you have.
