4、进行补充、 解释或附加说明,缺少也不会影响对全句的理解。它与主句或先行词之间一般用逗号隔开, 常常单独翻译, 没有它, 主句意思仍然完整。 引导非限制性定语从句的关系代词有 as, which, who,whom,whose 等,作定语从句的主语、宾语、表语及定语。关系副词有 when,where 等,作定语从句的状语。关系代词和关系副词在非限制性定语从句中一般不能省略,注意: that,why 不用来引导非限制性定语从句。 The sun,which rises in the east,gives us heat and light. 太阳从东方升起,带给我们光和热。 二、非限制性定语从句应
