Unit 3 语法思维导图及专练-2023-2024学年九年级英语全一册基础知识专项讲练（人教版）

Unit 3 Could you please tell me where the restrooms are? （语法讲练） 【知识导图】 【要点拓展】 1.连接代词和连接副词引导的宾语从句。 （1）连接代词：who、whom、whose、which、what，在从句中担任主语、宾语、定语或者表语。 （2）连接副词：when、where、why、how，在从句中担任状语的成分。 2.当疑问词在句中作主语或主语的定语时，变为宾语从句时语序不变，但时态应作相应变化。如： Who can answer the question? The teacher asked.→The teacher asked who could answer the question. Whose book is on the desk? We want to know.→We want to know whose book is on the desk. 【奇思巧计】 一是关键引导词，不同句词相异。 陈述句子用that，一般疑问if/whether替。 特殊问句更好办，引导还用疑问词。 二是时态常变化，主句不同从句异。 主现从不限，主过从必过，客观真理仍用现。 三是语序要记清，从句永远陈述序（特殊疑问词或主语或主语的定语时除外）。 【同步检测】 一、单项选择 1．Could you say it again?
