8、类）。2.每种分类的结构总结。3.做题思路。做题思路1（是基本句型）说明：由于考试时所考的陈述句变一般疑问句绝大多数都是源自所学过的基本句型。因此提供下列做题思路。1.识分类根据划线位置确定变化后的特殊疑问句的分类。2.查人称检查陈述句中是否有第一人称相关的词。若陈述句中含有情态动词，还需检查是否含有第二人称相关的词。3.转中文将划线部分遮住后，翻译成中文。（翻译时就要记得更改人称）4.想句型回忆所学的基本句型。5.现场套根据所学的基本句型为基础，现场更改及套用到基本句型中。6.勤检查。根据所背的对应分类的特殊疑问句的结构总结，来检查所写的句型结构是否正确。做题思路2（非基本句型）说明：万一要

9、是出现非基本句型，导致无法现场更改和套用，请用下列做题思路。（1,2,3与做题思路1中的相同）1.识分类根据划线位置确定变化后的特殊疑问句的分类。2.查人称检查陈述句中是否有第一人称相关的词。若陈述句中含有情态动词，还需检查是否含有第二人称相关的词。3.转中文将划线部分遮住后，翻译成中文。（翻译时就要记得更改人称）4.疑问词根据划线内容现场判断需选择哪个疑问词。5.现场写根据所背的对应分类的特殊疑问句的结构总结，现场写出答案。语法：特殊疑问句的分类一、如果疑问词对主语或主语的定语提问，则疑问词后的语序是陈述句的语序。如：（由于针对主语的定语提问的基本句型大多没有学。因此此处不给出具体例句。只需

10、理解主语的定语是什么意思即可）I am drawing the picture.Who is drawing the picture?/Who are drawing the picture?(除非明确知道是多个人在画画，不然则默认主语who指代的单数，因此be动词用is)I like spring.Who likes spring?/Who like spring?(除非明确知道是多个人喜欢春天，不然则默认主语为单数,需用like的三单形式likes）John can help my friend.Who can help your friend?思考：为何此句只有一种答案？（因为陈述句的谓

11、语由情态动词与动词原形构成。而情态动词没有人称与数的变化，因此答案只有一种）I watched TV before.Who watched TV before？（由于该句时态为一般过去时，其动词过去式只有一种，没有所谓的三单变化，因此变为特殊疑问句后只有唯一的正确答案。）I was young.Who was young?/Who were young?（该句的时态为一般过去时。陈述句为主系表结构。针对主语提问时，由于不知道主语指代的人为单数或复数，因此答案有两种。）（除非明确知道是多个人曾经年轻，不然则默认主语为单数,be动词需用was。）总结：疑问词谓语（宾语）（其他）？（对于现在进行时来

12、说，谓语=be+doing。对于系表结构的句子来说，谓语=be+表语）二、如果疑问词对其他成分提问，其语序是：疑问词一般疑问句的语序。（根据以前讲过的陈述句变一般疑问句的分类，将其分为以下几类）.种类一：含有be动词的陈述句（be动词不作实意动词）I am from China.Where are you from?She is young.Whats she like?Its seven oclock.What time is it？My friend is fine.How is your friend?Today is Tuesday.What day is it today?She i

13、s singing an English song.What is she singing?（此处be动词属于助动词，用作构成现在进行时）They are singing an English song.What are they doing?（此处be动词属于助动词，用作构成现在进行时）总结：疑问词+be动词+主语+（其他）？种类二：实意动词单独作谓语。She went home by bus.How did she go home?They like winter.Which season do they like?John watched TV.What did John do？She

14、watched TV at 8.When did she watch TV?Sarah and John feel well now.How do Sarah and John feel now?（注意：句中出现感官系动词时，将其当做实意动词处理，出现变化与持续系动词时的情况暂不要求掌握。）总结：疑问词+助动词+主语+动词原形+(宾语)+(其他)？种类三：“助动词+动词原形”一起作谓语。I will go to school tomorrow.What will you do tomorrow?（此处的will是助动词，用于构成一般将来时）总结：疑问词+助动词+主语+动词原形+（宾语）+（其他

15、）？种类四：“情态动词+动词原形”一起作谓语。He can dance.What can he do?I can eat healthy food.What food can you eat?I could see stars.What could you see?You should go home.What should I do?I could help you in my house.What could you do in my house?I could help you in my house.Where could you help me?John would like to
