A.what B.when C.that D.if 答案：B 解析：从句为特殊疑问句转化而来，询问”会议何时开始”，需用表时间的连接副词wh,符合” 特殊疑问句作宾语用疑问词引导”规则。 真题2（语法填空）： She asked_I could help her with her homework.(填入合适引导词) 答案：if/whether 解析：从句为一般疑问句转化而来，表”是否能帮忙”，需用if或whether引导，符合”一般疑问句 作宾语用if/whether'”规则。 考法二：引导词与语序综合判断 核心：根据从句类型选择正确引导词，并确保宾语从句使用陈述句语序 真题1（单项选择）： Do you knowthe meeting will start? A.when will B.when C.when does D.when is 答案：B 解析：从句为特殊疑问句转化的宾语从句，引导词用whm:宾语从句需用陈述句语序，即”引导 词+主语+谓语”，选项A、C、D均为疑问句语序，故排除。 初三下册北师大版 【寒假专版】 A版知识点全解 真题2（句子改错)： He asked that how he could get to the station. 答案：去掉hat 解析：宾语从句由特殊疑问句转化而来，引导词应用疑问词how,hat为陈述意义引导词，二者不 可同时使用，故删除that。 考法三：宾语从句引导词综合运用与语序判断 核心：结合从句类型选择合适引导词，掌握hat省略规则及if/whether区别，确保从句用陈述语序 真题1（单项选择)： Could you please tell me_the nearest post office is?I need to send a letter.
