2023年中考英语复习三大从句课件

初中英语三大从句 一、宾语从句 1.宾语： 1）I like English. 2）She enjoys watching TV. ★宾语是动作、行为的对象，是动作的承受者。 ★宾语由名词、代词、不定式或相当于名词的词、短语来担任。 2.宾语从句： 1）We know the man. 2）We know that he is a good man. 充当宾语成分的句子叫做宾语从句。 3.宾从的判断： 动词 介词 ＋ 宾语从句 形容词 4.★引导词： 1）that：that 在从句中无实际含义，不充当成分，在口语中往往省略。 e.g. I believe that you are the best. 2）whether/if: e.g. I asked whether he wanted to go shopping with me. if/whether 引导的宾语从句，表示“是否….”, 不能省略，在大部分情况下二者可以互换，但在以下情况中, 只能用whether，而不能用if。 ①后面有…or not；②在介词的后面； e.g: I am interested in whether he will come tomorrow. ③在不定式 to do 前 e.g: I don’t know whether to do it. ④ 在谓语动词discuss的后面 3） 特殊疑问词 疑问副词 含义 例句 充当成分 how 如何 He asked how he could finish the task. 方式状语 where 哪里 He asked where I lived. 地点状语 when 什么时候 He asked when I would leave for Beijing. 时间状语 why 为什么 He asked why I was worried. 原因状语 分两类：疑问副词和疑问代词。①疑问副词只能做状语 ②疑问代词可做主语、宾语、表语等成分。 疑问副词 含义 例句 充当成分 who 谁 I don’t know who cleaned the window. 主语、宾语和表语 whom 谁（作宾语） He asked whom I would meet. 宾语 what 什么 He asked what I liked. 主语、宾语 whose 谁的 He asked whose book this was. 定语、表语 which 哪一个 He asked which book I liked. 定语 5.★宾从的语序： 1）区分陈述语序& 疑问语序 陈述语序：主语+谓语+其他 疑问语序：谓语提到主语前（有情提情、有be提be、无情无be请求助） 2）宾从的语序：陈述语序 3）引导词在从句中作主语，从句语序与疑问句相同： ①What’s the matter? Would you tell me wha’s the matter? ②What’s wrong with you? She didn’t tell me what was wrong with you. 6.★宾从的时态： 主句为一般现在时，从句可以用语境所需要的任何时态. 主句为一般过去时，从句用相应的过去的时态。 从句内容为客观真理，从句仍然用一般现在时。 口诀：主现从随意，主过从过，真理永一现。 【课堂练习】 1．We don’t know________ , but it tells us the importance of friendship.
