( ) We don't know when they will arrive. (√) Could you tell me who is he waiting for? ( ) Could you tell me who he is waiting for? (√) 单元语法聚焦三 考点3:宾语从句在时态上应遵循时态呼应原则 在宾语从句中,谓语动词时态要受到主句谓语动词时态的制约,一般要遵循以下三条原则: 1.如果主句是祈使句或主句中的谓语动词是一般现在时或一般将来时,则宾语从句可根据实际需要选用时态。如: Mary says she will come back soon. Will you tell us which places you visited during the vacation? 单元语法聚焦三 2.如果主句中的谓语动词是一般过去时,则宾语从句需要使用表示过去的某种时态。如: He said that he played computer games last night. I knew she had cleaned the classroom already. 3.如果宾语从句所表达的是客观事实、真理、自然现象、名言、警句、谚语等,多用一般现在时。如: He said time is money. Our teacher told us that light travels much faster than sound. 单元语法聚焦三 考点4:宾语从句的“否定转移” 当主句的谓语动词为think, believe等词,且主语为第一人称时,从句中的否定词not应转移到主句谓语动词。如: I think. She can't come.(合并为一句) I don't think she can come. 考点5:宾语从句的简化结构 由特殊疑问词引导的宾语从句通常可以简化成“特殊疑问词+不定式”结构,此时主从复合句也就变成了简单句,但简化必须符合以下两种条件: 1.简单句的疑问词为原宾语从句的引导词; 2.原从句的主语应与主句的主语或间接宾语一致。 I don't know what I should do next.(改为简单句) I don't know _. what to do next 单元语法聚焦三 考点6:含有宾语从句的复合句的反意疑问句 1.陈述部分是“I/We think (know, believe, suppose, consider)+that从句”或者是“I'm/We're sure that; I'm/We're afraid that; I/We hope that; It seems that”时,附加疑问部分的主语应和从句一致,但需注意否定前移的情况。如: I don't think he is right, _? I'm sure that you know him well, _? is he don't you 2.如果主语是其他人称,附加疑问部分的主语和主句一致。如: Your father believed you could succeed, _? Kate doesn't know if Jim is a good singer, _? didn't he does she 考点7:宾语从句中人称的变化 注意宾语从句中人称代词的正确使用。一般遵循“一随主,二随宾,第三人称不更新”的原则。 Let’s practice Rewrite the questions to make them more polite. 4a Where can I buy some grapes or other fruit? 2.
