lead in

① I can see a boy. ② The boy is readi ng un der the tree. 合并这两个句子：I can see a boy is

readi ng un der the tree.

二、定语从句的相关概念

1、复合句：复合句是相对于简单句来说的，简单句是只有一个谓语动词的句

子，而复合句是由两个或两个以上的谓语动词够成的。复合句又分为并列复

合句和主从复合句。并列句是由and, but, or等并列连词来连接的句子。而主

从复合句是由从属连词来连接的句子，包括主从，宾从，表从，定从，状从,

同位语从句等。

Eg: He is a student.(简单句He is a good student so that we all like him.复合句)

I hope you will succeed. I think you are right.

①在复合句中作定语，修饰某一个名词或代词的从句叫做定语从句。

②先行词：被定语从句修饰的那个名词或代词叫做先行词。

③关系词：关系词由关系代词和关系副词来引导。

④句型:可分为限制性定语从句和非限制性定语从句。

Eg: (1) I see a girl who is cryi ng.

't a good man.

(2) He who doesn ' t reach the Great Wall isn 3、定从的两个表格：

四、定语从句的做题步骤：①先判断是否是定语从句（从定义）【定定从】

②找先行词（名词或代词）

③明确从句所缺成分（主、宾、表、定或状）

④定关系词（主、宾、表、定一关系代词，状语T关系副词）五、注意事项:

（一）只用that不用which的情况①当先行词为不定代词时（somethi ng, some one, anyon等）

②当先行词前有形容词最高级修饰时

③当先行词前有序数词修饰时

④当先行词既有人又有物时

⑤当先行词前有the very, the only, the last, just, no, little, few等时

⑥当主句是以who, which 开头的疑问句时⑦当主句是there be结构时
