1. 限制性定语从句可以由_关__系__代__词__、 _关__系__副__词___来引导，关系代词作宾 语时可以省略。
2. 非限制性定语从句既可修饰_先__行__词_, 又可修饰_整__个__主__句___, 不可用 that 引 导且关系代词不可以省略。

注意：
1 非限制性定语从句中, 指物时, 用 which 而不用 that。
2. 非限制性定语从句： 从句对先行词关系不密切, 去掉定语从句, 意思仍然完整。形式上用逗号隔开, 不能 用that 引导。
e.g. Tom’s father, who is over sixty, still
works hard day and night. (who 引导非限制性定语从句, 整个句 子可分成两句来翻译)
2 指人时主格用who, 宾格用whom, 物主 格用whose (也可指物)。
➢ Miss Howe, whom you met in the library, is our new teacher.
➢ The Arabs, who are famous for their horses and camels, use these animals for work and in sports.
2. Shanghai, which is in East China, is developing quickly.
当先行词是地名、人名、世界上独 一无二的事物或家庭唯一成员时， 通常只用_非__限__制__性__定__语__从__句__修饰。
