35、. （定语从句） 刚刚起飞的那架飞机是开往巴黎的。The fact that he has already died is quite clear. （同位语从句） 他已经去世了，这个事实很明了。2定语从句由关系代词或关系副词引导，关系词在从句中担当相应的句子成分，关系代词在从句中作宾语时经常可省略。同位语从句主要由连词 that 引导，在从句中一般不担当成分；有时也由 where, when, how, who, whether, what 等连词引导，这些连词则在从句中担当成分。The news that he told me is true. （定语从句） 他告诉我的消息是真的。The
