( one之前有“the only“或“the very修饰时，one就是先行词.故从句的谓语动词应该使用单数形式)他是学生中唯一迟到的一个。【巧学记忆】关系代词的用法.:关系词来引定从，它们的用法各不同. That可做主宾用，指人指物它都行.which只能指物用，主宾定语它也能。who和whom指人用，分作主宾要弄清。whose一词真叫行，指人指物都能用。时间状语when才行，地点状语where能。原因状语why对应, as用作主和宾。修饰全句或部分，which和as要分清。固定搭配应分明，从句当中定功能。考点突破考点1 考察关系代词的用法1.(哈尔滨中考)Everyone has his aim in life.
