16、，引导定语从句的词叫关系词。 (2) 如何确定关系词方法一：准确判断关系词在定语从句中的成分，关系词作主语、宾语，用关系代词；关系词作状语，用关系副词；关系词作定语则用whose, 或which。方法二：看定语从句中的谓语动词是及物动词还是不及物动词。如是及物动词，用关系代词；不及物动词则用关系副词。2，although与 while相同点：都是连词，都可引导让步状语从句；不同点：although意为“虽然，尽管”，相当于though，所引导的句子通常置于句首。含although从句的复合句可以转化为由but引导的并列句，但although与but不能同时出现；while意为“然而，但是”，可用作并列连词，表示前后的对比，一般不与but转换，所引导的句子不能置于句首。教学后记The Ss cant grasp the attractive clauses.3 版权所有高考资源网
