13、 true.他说他是一个法国人，这不是真的。2为避免关系词的重复，被关系代词所代替的成分不可在从句中重复出现。This is the factory which we visited last Sunday.(visited 后不可加 it)这就是我们上星期天参观过的工厂。3关系代词的省略。(1)关系代词作主语时不能省略。(2)作动词宾语的关系代词，可以省略；作介词宾语的关系代词，如果不直接位于介词后，可省略，如果直接作介词的宾语，不能省略。(3)关系代词 which 在非限制性定语从句中不能省略。即时演练 2语法填空All things can be done has (have) been
