中考英语“肯定句变一般疑问句”万能解题步骤、技巧和典例精析.doc

“肯定句变一般疑问句”解题步骤 一、 找be动词（am is are，was were）有则直接提前； eg1. He is / was a teacher. Is / Was he a teacher? 肯Yes, he is/was 否No, he isnt/ wasnt.二、 无be动词，则再找情动(can may should must need)有情动则直接将其提前； eg2.I can play soccer. Can you play soccer? 肯Yes, I can 否No, I cant. (注:cant容易多写n)注：need有可能不是情态动词，怎么判断？根据 “情态动词+V原”的共性。因为： need 、情态动词：“需要”，后接: V原 、实义动词：“需要”，后接：sth 或 to do sth.eg3. You need see a doctor. Must I see a doctor? 肯Yes, you need. 否No, you neednt.eg4. You need to see a doctor. Do I need to see a doctor? 肯Yes, you dont. 否No, you dont.(eg3中的need根据“情态动词+V原”的共性可以判断是情动，但通常也不提前，要根据语气选择must开头,同样must开头的一般疑问句的否定回答，一般要选择用neednt或dont have to作答。eg5.-Must I stay here ? 肯Yes, you must . 否 No, you neednt 或No, you dont have to.三、 无be动词，无情动，则再找是否有助动词will,shall,would,have,has,had,有则直接将其提前；注：have,has,had有可能不是助动词，怎么判断？根据 “完成时态” 的结构。因为只有“完成时态”中才会有助动词have,has,had的存在，其他时态或位置的have,has,had都是实义动词。 “完成时态结构”如下：、 现在完成时：have / has + V-ed(过去分词) eg. I/She have / has done my homework.、 过去完成时：had + V-ed(过去分词)eg. She had left before/when I realized she was a cheat(骗子). eg. We had finished cleaning the classroom before the teacher came.、 现在完成进行时: have / has been V-ing(现在分词) eg. I have been swimming in the cold water for about two hours.四、 无be，无情，也无助，则只有借助 疑问句专用助动词do,does或did，并将其提前后，且原实义动词形式务必要还原；五、 变人称：原句中涉及第一人称的人称代词、形容性物主代词、名词性物主代词要变成第二人称对应的人称代词、形容性物主代词、名词性物主代词；同样，原句中涉及第二人称的人称代词、形容性物主代词、名词性物主代词要变成第一人称对应的人称代词、形容性物主代词、名词性物主代词；eg. I like apples. Do you like apples ? 肯Yes, I do 否No, he doesnt.eg. This is my book. Is this your book? 肯Yes, it is 否No, it isnt.eg. That computer is mine. Is that computer yours? 肯Yes, it is 否No, it isnt.eg. You are my friends. Am I your friends? (Be动也变化了) 肯Yes, you are 否No, you arent.六、 some或与some有关的不定代词要变成any及any有关的不定代词。someany, somethinganything, somebodyanybody, some oneany one, somewhereanywhere 不变的特殊情况如下：eg. I would like some drink.(变一般疑问句) Would you like some drink?原因是：表示发出诚恳的请求希望得到别人的肯定回答，或征求建议的一般疑问句，只能使用表示肯定的some 或 something 等不定代词。七、附：句中含有 “used to + V原”结构的变一般疑问句时，有两种变法：1、借助助动词did 且提前，used 还原成use. eg.I used to watch TV after dinner. Did you use to watch TV after dinner? 肯 Yes, I did. 否No, I didnt.2、也可直接将used提前.eg.I used to watch TV after dinner. Used you to watch TV after dinner? 肯 Yes, I used. 否No, I usednt. 八、在含有 “ I think, I guess（guessed）, I believe(believed)”等引导的宾语从句中，变疑问句时，无须考虑从句部分是否有be动词、情态动词或助动词，只需把主句部分变为疑问语序就可。变成：I think/guess/believe Do you think/guess/ believe？ I thought/guessed/believed Did you think/guess/believe？I dont think/guess/believeDont you think/guess/believe？难道你不认为I didnt think/guess
