从句不缺主干成分，但需要添加意思——状语
解题步骤第一步：识别名词性从句的种类1．首先确定主句的谓语动词，确定主句的主谓结构。2．分析从句在主句中所充当的成分，确定从句所属类型：主语从句、宾语从句、表语从句、同位语从句。第二步：分析从句结构，确定从句引导词确定从句的结构和意义是否完整，结合句意填写适当的连接词。1．若从句结构完整，用从属连词：陈述事实用that；表示疑问“是否”用if或whether。2．若从句缺少主语、宾语或表语，则考虑用连接代词。3．若从句缺少状语，则用连接副词。

口诀： 主过从必过 主现从不限 客观真理用一现
主过从必过（主句是过去时，从句也要用过去的时态）I nly knew he was studying in a western cuntry, but I didn’t knw what cuntry he was in.我只知道他当时在西方的一个国家读书,可不知道是哪个国家。He asked me if I was reading the stry The Old Man and the Sea when he was in. 他问我他进来的时候我是否正在读《老人与海》。He tld me that he had tld Mary abut the meeting already.他告诉我他已经把有关会议的事情告诉的了玛丽。The reprter asked if the gvernment wuld take necessary measures t prevent the pllutin.记者问政府是否会采取必要的措施预防污染。
主现从不限客观真理用一限如果从句是一个客观真理,那么从句的时态不根据主句的时态而变化The teacher said that the mn ges arund the earth yesterday.老师昨天说月亮绕着地球转.
一律用陈述语序，即主语+谓语+
