人教英语九上教案单元主题写作三内容摘要：

now when will they arrive. ( ) We don39。 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 注意：特殊疑问词作主语时，如果语序本来就是“主语＋谓语”结构，则语序不再变化。 如： Please tell me. Who will give us a talk this afternoon。 (合并为一句 ) →Please tell me ________________ us a talk this afternoon. who will give 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 e 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 puter 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 can39。 t e.(合并为一句 ) →I don39。 t think she can e. 单元语法聚焦三 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 don39。 t know what I should do next.(改为简单句 ) →I don39。 t know ____________________. what to。
