Unit 1 Wish you were here Grammar & Usage 详解课件 新译林2020版 选必三 非限制性定语从句的用法 定语从句可以分为限制性定语从句和非限制性定语从句。非限制性定语从句由关系代词和关系副词引导，但不能用that引导。例： 多伦多是我常想去参观的一个城市。 Toronto is a city (that) I’ve always wanted to visit. 限制性定语从句 非限制性定语从句 他借给我一本词典，这正是我所需要的。 He lent me a dictionary, which was just what I needed. 劳拉不能来参加我们的聚会，这真遗憾。 Laura couldn’t come to our party, which was a pity. 戴维斯想参观袁博士的新农场，那里种了海水稻。 Davis wanted to visit Dr Yuan’s new farm, where the seawater rice was grown. 非限制性定语从句的用法 限制性定语从句与其所修饰的先行词关系密切，在意义上是先行词不可缺少的定语，如果省略，主句意义往往不完整；而非限制性定语从句和主句的关系并不十分密切，它往往是对先行词或整个主句的附加说明，与主句之间通常用逗号隔开。例： A five-year-old boy can speak two foreign languages, ___ surprises all the people present.
