高中定语从句教学

　　对比法导入：

black bag is beautiful.

2. The bag which you bought yesterday is beautiful. 不同：第一个形容词作定语，第二个句子作定语。

我有一只苹果。那只苹果是红色的。

我有一只红色的苹果。(除了用I have a red apple. 还可以用一个定语从句来表达) I have an apple. The apple is red.

I have an apple that / which is red.

I like some friends. Some friend like sports. (用定语从句合并成为一个复合句)

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.

　　如何合并两个简单句成为一个定语从句?

找错误：(结论：先行词不能出现在定语从句中)

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.

定语从句:在复合句中作定语，修饰名词或代词的从句。这种从句由关系代词或关系副词引导，并作句子成分。

关系代词：引导定语从句的代词，在句子中充当名词作用，有： Who, whom, which, that, whose, as

关系副词：引导定语从句的副词，在句子中充当副词的作用。 有：when, where和why

限制性定语从句(识别性从句)：对先行词起修饰限制作用，如果去掉，主句意思就不完整明确，与主句的关系十分密切。

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

非限制性定语从句(补充性从句)：对先行词作附加的说明，与主句的关系不十分密切，较松散。从句和主句之间用逗号分开, 相当于一个插入语, 不能用that和why(可以用for+which)引导，关系代词做宾语时也不能省略。 night, I saw a very good film, which was about the Long March.讨论：讨论关系代词与关系副词在以下定语从句中的不同作用。 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.

考点一:如何判定用关系代词还是用关系副词

方法一、找出定语从句中是否主语和宾语都齐全。如齐全用关系副词。 用什么关系副词看先行词。 you made such a great success. The reason ___ she gave was not true.

方法2、确定定语从句的`谓语动词是不是及物动词，如是，用关系代词，如不是，用关系副词。(常用常考) 方法3、如定语从句中谓语结构是被动结构，有主语，则用关系副词。 October 1st is the day ________ new China was founded. 考点二：that/which 代物时用that的情况

　　看例子，找规律：

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

1.先行词是最高级形容词或它的前面有最高级形容词修饰时。

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

2.先行词是序数词，或它前面有一个序数词时。

3)You should hand in all that you have.
