聚焦定語從句

1、聚焦定語從句溫故知新我們初中的時候學過形容詞、名詞等作定語來修飾某一名詞或代詞。那么句子可以作定語嗎？可以！如果一個句子充當了定語，那么我們稱之為定語從句。先來看這樣兩個句子：1) The man is my English teacher. 2) I met him in the street. 如果想把這兩個句子合并成一個句子，我們可將句2) 轉換成定語從句來修飾the man，即：The man that / who / whom I met in the street is my English teacher. 這個句子中的that / who / whom I met in the

2、 street 就充當了the man的定語，它就是定語從句；而被修飾的the man叫做先行詞。另外，你發(fā)現了嗎？句2)中的him換成了關系代詞that / who / whom，并放在了定語從句的最前面，我們把that, who, whom等詞叫做引導詞。例句呈現1. Is he the man that / who sells the dog?2. Do you know the boy whom / who / that I talked with just now?3. She was not on the train that / which arrived just now.4.

3、 What do you think of the photos that / which I took in the park?5. The book whose cover is green was lost yesterday.6. The first place that we visited in Beijing was the Great Wall.7. It was the largest map that I ever saw.8. I have read all the books that you lent me.9. Is there anything else that

4、 I can do for you?10. They talked about the people and things that they remembered in the old days.11. Who is the man that shook hands with you just now?小結歸納 關系代詞that, which, who, whom, whose都可以引導定語從句，使用它們時我們應該考慮兩點：1. 先行詞是“人”還是“物”；2. 關系代詞在定語從句中所充當的成分。 首先，當先行詞是“人”時：1) 關系代詞在定語從句中作主語時，用that / who，如：句1；

5、2) 關系代詞在定語從句中作賓語時，用whom / that / who，如：句 2。 其次，先行詞如果是“物”時：可用關系代詞that / which來充當主語或者賓語，如：句3、4。 綜上所述， that既可以指“人”又可以指“物”，而which只能指“物”，who / whom只能指“人”；who / that / which 都可以作主語或賓語，而whom只能作賓語；此外， whose 在定語從句中放在某一個名詞或代詞前作定語，如：句5。特別需要指出的是：當關系代詞作賓語時常常省略，而作主語時則不能省略，如：句2、4、6、7、8、9、10中的關系代詞可以省略；而句1、3、11中的關系代

6、詞不可以省略。 另外，還有一些情況一般只用that引導定語從句：(1) 當先行詞被序數詞或形容詞的最高級修飾時，如：句6、7；(2) 當先行詞被all, some, any, no, little, much等修飾時，如：句8； (3) 當先行詞是everything, anything, nothing等不定代詞時，如：句9；(4) 當先行詞既有人又有物時，如：句10；(5) 當主句以疑問詞who或which開頭時，如：句11。即學即用請完成下列句子。1.
