九年级上册,英语教学课件系列,Unit 3 Teenage problems Grammar,A Object clauses introduced by question words,We use a question word to introduce an object clause that expresses a wh- question. The word order in the clause should be the same as that in a statement.,Whom is an object pronoun. We can use who instead of whom.,Tip,2019/4/3,I wonder what I should do. Daniel does not know whom he should talk to. Sometimes we forget when we should stop. I do not understand why they are so strict with me. I do not know how I should deal with the problem.,2019/4/3,一、宾语从句的概念,在句子中起宾语作用的从句叫做宾语从句。 We know Mr Green teaches English. She asked if these answers were right.,二、宾语从句三要素,引导词（连接词） 语 序 时 态,Summary,2019/4/3,特殊疑问词引导的宾语从句 当宾语从句是特殊疑问句时，用疑问词作引导词。特殊疑问词引导宾语从句时，特殊疑问词不可省略，而且宾语从句要用陈述句语序。,特殊疑问词引导的宾语从句,2019/4/3,常见的疑问词: where：哪里（状语） what ：什么 when：问时间 (回答用At/ On.等) which：哪一个，哪个 who ：谁 ( 回答用He is.She is. They are.等） whom： 谁（宾格） whose：谁的 (回答用It is These/Those are等) why： 为什么 (回答用Because，问原因) How：怎么样(回答用形容词，问程度） 记法：特殊疑问词的开头一般是wh或h。,2019/4/3,Where will we have a meeting? 我们将在哪儿开会？ Could you please tell me where we will have a meeting? 您能告诉我我们将在哪儿开会吗？ What should I do next? 下一步我该做什么？ I wonder what I should do next? 我想知道下一步我该做什么？,2019/4/3,2. 含宾语从句的复合句与简单句的相互转换 含有疑问词引导的宾语从句的主从复合句中，若主句的主语或宾语与从句的主语一致，则宾语从句可以变成“疑问词+动词不定式”的形式。 I dont know how I should do it next. I dont know how to do it next. 我不知道下一步应该怎样做。,2019/4/3,3. 改写宾语从句的三个关键点： (1)确定从句的引导词：宾语从句的引导词要 根据从句句式来确定，其对应情况如下表：,(2)确保从句语序正确：无论原句是何种句 式，宾语从句要用陈述语序。,2019/4/3,(3)确定从句时态：在主句时态确定的情况下, 宾语从句的时态对应如下：,2019/4/3,I dont know where he lives. 我不知道他住在哪里。 I believe that they will come soon. 我相信他们很快会来。 He asked me whether I was a teacher. 他问我是否是老师。 The teacher said that the earth goes round the sun. 老师说地球围着太阳转。（从句为客观真 理，不受主句时态限制）,宾语从句用法 宾语从句需注意，几点事项应牢记。 一是关键引导词，不同句子词相异。 陈述句子用that；一般疑问是否（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。主句若为现在时，从句时态应看意；主句若为过去时，从句时态向前移。 三是语序要记清，从句永保陈述序。,巧学妙记,More problems and questions A1 The Class 1, Grade 9 students are talking about their problems.
