宾语从句我全解.pptVIP

宾语从句语序：陈述句语序 主句 +连 接 词 +主语 +谓语 +其他成分. 1.连词that引导：作从句的原句是陈述句。 I hear（that） English is not easy. 2.if/ whether “是否”，用它引导从句， 说明对陈述的事物不明确或不清楚。常用在ask, wonder, can(could) you tell me 等后。原句为一般疑问句，选择疑问句或反意疑问句。 Could you tell me if (whether) Miss Brown lives in that house? 3.当从句原本是特殊疑问句时，用以下连接代词和连接副词引导： what, which, who, whom, whose, when, where, how, why, how far, how long, how many, how much, how often… 作用：连接主句和从句，并在从句中担任句子成分，具有一定的意义。 eg:I didn’t hear __ what__he wanted me to do. I want to know __ who __is that young man. Tom asked us__ when __we would start the party. 一般疑问句变宾语从句的步骤：1、把句子变为肯定句 Is Jim at home? Jim is at home. 2. Is June a good time to visit Hong Kong? June is a good time to visit Hong Kong. 3. Does he like sports? He likes sports. 4. Will they play basketball after school? They will play basketball after school. 2.在句子前加上从属连词 whether, if 变化方法： 主句 + if / whether + 一般疑问句。 if/whether 引导宾语从句 ，表示“是否”之义， 在句中不充当句子成份， if/whether可互换。 但if常用于口语中，whether比较正式 只能用whether不能用if的情况 1.在介词后面： I’m thinking of whether we should go fishing. We didn’t think about whether it would rain the next day. 2.在动词不定式前： They asked me whether to sit at the front. 3.当与or not连用，或提出两种选择 时: I don’t know whether he’s free or not. Mary asked whether I was doing my homework or not. Tell me whether you’d like to go shopping or tidy the room. 4.宾语从句提前时： Whether this is true or not, I can’t say. 5.在动词discuss后的宾语从句中: We discussed whether we would have a sports meeting next week. 6.引导表语从句或位于句首的主语从句用whether： Whether he is right or wrong is a question. The question was whether he went there last night. 用if不用whether的情况: 1.引导否定概念的宾语从句时： He asked me if I hadn’t finish my homework. 2.引导条件状语从句，if意为“如果”时: We’ll go hiking if it doesn’t rain tomorrow. 把下列各句变为宾语从句 Is Jim at home? (I wonder…) I wonder whether / if Jim is at home. 2. Is June a good time to visit Hong Kong? ( He wonders…) He wonders whether/ if June is a good time to visit Hong Kong. 把
