After listening to the scientists who had studied the problem, and citizens who lived near the problem, the government turned to the United Nations for help. Temples and other cultural sites were taken down piece by piece, and then moved and putback together again in a place where they were safe from the water. (refers to people) (refers to a place) Part 01 Presentation 定语从句 在复合句中,作定语修饰名词或代词的从句。 The couple who live next to us volunteered to help after the volcano erupted. 先行词 定语从句所修饰的名词或代词叫做先行词。 关系词 连接主句和从句 指代先行词 在从句中充当句子成分 (作用) 关系代词 关系副词 who whom whose that which as when where why that 关系代词 用法: 关系代词除了指代主句中的先行词外,同时还在定语从句中作主语、宾语、表语等。作宾语时可以省略;但关系代词作介词宾语,而且介词提到它的前面时,关系代词不能省略。 关系代词 修饰的先行词 在从句中所作的成分 who 人 主语、宾语 whom 人 宾语 whose 人或物 定语 that 人或物 主语、宾语、表语 which 物或事 主语、宾语、定语、表语 as 人、物或事 主语、宾语、表语 限制性定语从句 紧跟在修饰对象(即先行词)之后的定语从句, 先行词和限制性定语从句之间紧密相连,前后相接。 非限制性定语从句 先行词与定语从句没有紧密相连,而是被逗号或其它语句部分隔开。 限制性定语从句与非限制性定语从句的区别 限制性定语从句与非限制性定语从句的区别 (1)作用不同 限制性定语从句是先行词在意义上不可缺少的定语,不可去掉,否则主句意思不完整。非限制性定语从句对先行词进行补充说明,可去掉,去掉后主句意思仍完整。 This is the best film (that) I have ever seen for years. 这是几年来我看过的最好的一部电影。 She lost the match, which depressed her greatly. 她输了比赛,这使她很沮丧。 去掉后影响对电影的限定范围 去掉后不影响她输掉比赛这个事实 限制性定语从句与非限制性定语从句的区别 (2)形式不同 限制性定语从句与主句不用逗号隔开,非限制性定语从句用逗号与主句隔开。 (3)先行词不同 大多数限制性和非限制性定语从句的先行词往往为某一个词或短语,而特殊情况下非限制性定语从句的先行词也可为整个主句,此时非限制性定语从句常由 which引导。 The two policemen were completely trusted, which in fact they were. 那两个警察完全受到信任,事实上也确实如此。 限制性定语从句与非限制性定语从句的区别 (4)关系词的使用情况不同 1. that不可用于引导非限制性定语从句。 2.关系代词whom在限制性定语从句中作宾语时可用who代替但whom在非限制性定语从句中作宾语时不可用who来代替。 3.关系代词的省略情况不同:关系代词在限制性定语从句中作宾语时可省略,而非限制性定语从句的所有关系词均不可省略。 The two policemen were completely trusted, which in fact they were. 那两个警察完全受到信任,事实上也确实如此。 which的用法 在定语从句中作主语、宾语,偶尔作定语或表语。 The river which runs through the centre of the city brings us lots of pleasure. 穿过市中心的那条河给我们带来了很多欢乐。 (which 在从句中作主语) Do you remember the holiday (which) we spent together 你记得我们一起度过的那个假期吗 (w ... ...
