定语从句
导学案
Period 1
Step 1. Lead-in
Pumas are large, cat-like animals which are found in America.

Step 2. Presentation

一、定语从句的定义、类别、要素
)
(
有最基本、最核心的主语和谓语,才能称之为从句。
)定语从句= 定语 + 从句
(
修饰名词或代词。
)
(
限制性定语从句
)定义:修饰一个名词或代词的从句被称为定语从句,一般紧跟在它所修饰的名词或代词后面。
定语从句类别
(
非限制性定语从句
)
在非限制性定语从句中,先行词与定语从句往往由逗号隔开,定语从句补充说明先行词,而此时的先行词可以是一个单词或前面一整个句子。例如:
He scored 69 in last English test, which was a great success.
(

先行词:
被定语从句修饰的
名词或代词

)
(

关系词:
关系词是用来引导定语从句的连接词。
)定语从句二要素
(
关系代词:
that, which, who, whom, whose

)
关系词(也称之为连接词)
(
关系副词:
when, where, why

)

三、关系代词特殊用法记忆
)
I. 在限制性定语从句中,只能用that不能用which的几种情况:
特殊情况 例句
①当先行词是all, much, little, few, none, anything, nothing, everything, the one等不定代词时; Eg. Do you have anything that you want to say for yourself
② 当先行词被the only, the very (恰恰,正好), any, every, some, no, all, few, little, much, the right, the last, just 等词修饰时。 Eg. This is the very idol that I am encouraged by.
③当先行词是形容词最高级或先行词的前面有形容词最高级修饰时。 Eg. This is the most touching film that I have ever seen.
④当先行词是序数词或它前面有序数词修饰时。 Eg. This train is the last that will go to Zunyi. Eg. What is the first American film that you have seen
⑤当先行词既有人又有物时。 Eg. Look at the girl and her dog that are crossing the street.
⑥当主句的主语是疑问词who或which时。 Eg. Which is the bike that you lost Eg. Who is the girl that won the gold medal
⑦有两个定语从句时,其中一个关系代词宜用which, 另外一个宜用that。 Eg. They secretly built up a small factory, which produced things that could cause pollution.
⑧当先行词在主句中作表语,且关系词也在从句中作表语时。 Eg. Shanghai is no longer the city that it used to be.
⑨主句是there be句型且关系词在从句中作主语时,用that不用which引导。 Eg. There is a seat in the corner that is still available.
II. 当先行词指事或物时,定语从句中关系代词用which 不用that的情况:
特殊情况 例句
①在非限制性定语从句中。 Eg. The sun heats the earth, which is very important to us.
②当动词短语中的介词提前时,用which不用that。但要注意,在一些固定搭配的动词短语中,由于动词和介词不可分割,因此不能把介词置于关系代词之前。 Eg. This is a house in which Lu Xun once lived. Eg. This is the pen (that/which) I am looking for. (√) Eg. This is the pen for which I am looking. (X)
③先行词后面有插入语时。 Eg. Here is the English Grammar book, which, as I have told you, will help you improve your English.
④当先行词本身就是that时。 What’s that which flashed in the sky just now 刚从天空一闪而过的是什么?
