What is the attributive clause? (什么是定语从句）
修饰一个名词或代词的单词或短语叫定语，如果定语为一个句子则称为定语从句，一般紧跟在它所修饰的名词或代词后面。
I knw the by wh is sitting n the desk.
I knw the by.The by is sitting n the desk.
定语从句是在句子中作定语，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.因形容词 通常做定语，所以又称之为形容词性从句。
Attributive clause:
定语从句的位置：通常在先行词（在主句中）后。
wh(主语、宾语)，whm(宾语)，that(主语、宾语), whse(定语)
that(主语、宾语),which(主语、宾语)whse(定语)
where (地点状语)
when (时间状语)
This is the by wh wn the first prize in the English Speech Cmpetitin.1. 主句：在含有定语从句的复合句中，除去定语从句后的部分，是句子的主句。2. 定语从句：修饰主句中的一个名词或代词的句子是定语从句。（修饰the by)3. 先行词：先行词就是被定语从句修饰的名词等，它总是出现在定语从句的前面。4. 关系词：关系词指用来引导定语从句的词，分为关系代词和关系副词。
升级为Tw thirds f the peple that/wh lived there were dead r injured.
升级为：There were deep cracks that/ which appeared in the well walls.
1.There were deep cracks . The cracks appeared in the well walls.
Make up attributive clause.
用that/ which 替代,被替代的词不再出现
2. Tw thirds f the peple were dead r injured. These peple lived there.
用that/ wh 替代,被替代的词不再出现
①指人时可以用wh,也可用that D yu knw the by wh/that is my desk mate? The man wh/that was killed in the accident is Tm's uncle.②指物时可以用which,也可用 that I like visiting places which/that are nt far away. Hw d yu like the film which/that was shwn last Sunday?③ whse 可以指人也可以指物，表示从属关系“的” He was a painter whse pictures were nt well-knwn in his life time. The tree whse leaves are red was planted last year.④关系代词作宾语时可以省略 I like the meal (that/which) we had last night. D yu knw the by (wh/whm/that) we talked abut just nw?
A. 作定语从句的一个句子成分 This is the bk that I have been lking fr.B. 连接主句和从句 I have a huse and its windws are very big. I have a huse, whse windws are very big. I have a huse; its windws are very big. I have a huse, its windws very big.C. 指代先行词的意思 He wrks in a factry, which is nt far frm his hme. （which指代factry，并在定语从句中作主语）
定语从句的关系代词的作用：
Eg: This is the schl ____ I nce studied.一找：找主句、从句、先行词 This is the schl ____ I nce studied.二还：根据先行词，把定语从句还原为完整的一句话(添词) I nce studied at the schl.三提问：对添加部分进行提问（用关系词替代添加部分） 对主语/宾语提问用代词，wh(that)/whm/which(that)/whse; 对状语提问用副词，when/where/why。 at the schl在作地点状语，故用where提问
关系词的选择技巧：一找、二还、三提问
6. I'll never frget the days ____ we spent tgether. A. that B. / C. when D. A and B 解析：We spent the days tgether. 主 谓 宾语 关系代词：which/that/省略
关系代词作宾语时可以省略
