七年级英语上改一般疑问句.doc

如何改一般疑问句 首先看句中是否有情态动词【1. can, could, may, might, must, will, would, shall, should, had better, used to 2. need, dare(敢) 二者只有在疑问句及否定句中才能用作情态动词】，助动词，be动词，如果有，把它们提到句首即可。如果没有，必须在句首加助动词do、does 或did。注意点：1.do、does用于一般现在时，does用于主语是第三人称单数。do用于主语是其它人称及数。2. did 用于一般过去时，且无人称及数的变化。3.用了助动词does、did后，原句中动词三单式及过去式必须改为动词原形。4do、does、did作为实义动词“做”时，不能运用其改疑问句及否定句。5. have(has、had) 只有在完成时中才是助动词。即才能运用其改疑问句及否定句。6.陈述句中如果有第一人称的人称代词、物主代词、反身代词，改疑问句时，要改为相应的第二人称的人称代词、物主代词、反身代词。7.陈述句中如果有some及some有关的词，改疑问句时，要改为any及any有关的词。如何回答一般疑问句用yes作肯定回答，用no作否定回答。其结构：Yes, 主语+句首动词。No, 主语+句首动词+not【主语必须是人称代词主格。there be结构除外.】 注意点：yes在回答否定的一般疑问句及陈述句是否定的反意疑问句时，其含义是“不”。 no在回答否定的一般疑问句及陈述句是否定的反意疑问句时，其含义是“是”。不论yes翻译成“是”还是“不”，永远都是肯定回答，后永远跟肯定式。 不论no翻译成“不”还是“是”，永远都是否定回答，后永远跟否定式。把下列句子改为一般疑问句并作肯定与否定回答。1. I am Mary.2. My name is Mary.3. Lily cant speak Chinese well.4. He has an interesting book.5. Tom often does his homework in the evening.6. There is some milk in the glass.7. There are some apples on the tree.8. His sister wants to something to eat.9. Her brother watches TV every evening.10. This isnt an old bike.11. That is an orange orange.12. Those are some knives in the box.13. His mother read newspaper every morning.14. She often bought something on weekends last year.15. Lucy often did housework at noon last year.16. Li Lei has been to Beijing twice.17. The twins have got the same sweater.18. The Whites always have supper at home.19. Li Lei hasnt seen Mary since she left here.20. He has lived in Shanghai for ten years.21. Need Tina return her hometown next week? (作肯定与否定回答)22. Must Lily finish her work in two days? (作肯定与否定回答)注意：1.need和 must 一般疑问句的肯定回答都用 must.否定回答都用neednt.主要因为mustnt表强烈禁止；need 在肯定句中不能用作情态动词。 2.need 用作情态动词时，无人称，时态及数的变化。后必须跟动词原形。用作行为动词，后跟动词，该动词用什么形式取决于主语和 need 后跟的动词之间的关系。二者如果是主动关系，该动词用动词不定式；二者如果是被动关系，该动词用动名词或动词不定式的被动结构。 1. He needs _ (repair) the computer. 2. The computer needs _ (repair). 3. Tom _ a new bike. （多选题） A. needs buy B. needs to buy C. neednt buy D. neednt to buy E. need buying F. needs buying G. need buy H. doesnt need to buy I. doesnt need buy由此可见，need 只有在疑问句及否定句中才能用作情态动词，在疑问句及否定句中不一定用作情态动词。3
