中考英語“肯定句變一般疑問句”萬能解題步驟、技巧和典例精析

1、 “肯定句變一般疑問句”解題步驟 一、 找be動(dòng)詞（am is are，was were）有則直接提前； eg1. He is / was a teacher. Is / Was he a teacher? 肯Yes, he is/was 否No, he isnt/ wasnt.二、 無be動(dòng)詞，則再找情動(dòng)(can may should must need)有情動(dòng)則直接將其提前； eg2.I can play soccer. Can you play soccer? 肯Yes, I can 否No, I cant. (注:cant容易多寫n)注：need有可能不是情態(tài)動(dòng)詞，怎么判斷？根據(jù) “情

2、態(tài)動(dòng)詞+V原”的共性。因?yàn)椋?need 、情態(tài)動(dòng)詞：“需要”，后接: V原 、實(shí)義動(dòng)詞：“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根據(jù)“情態(tài)動(dòng)詞+V原”的共性可以判斷是情動(dòng)，但通常也不提前，要根據(jù)語氣選擇must開頭,同樣must開頭的

3、一般疑問句的否定回答，一般要選擇用neednt或don't have to作答。eg5.-Must I stay here ? 肯Yes, you must . 否 No, you needn't 或No, you don't have to.三、 無be動(dòng)詞，無情動(dòng)，則再找是否有助動(dòng)詞will,shall,would,have,has,had,有則直接將其提前；注：have,has,had有可能不是助動(dòng)詞，怎么判斷？根據(jù) “完成時(shí)態(tài)” 的結(jié)構(gòu)。因?yàn)橹挥小巴瓿蓵r(shí)態(tài)”中才會(huì)有助動(dòng)詞have,has,had的存在，其他時(shí)態(tài)或位置的have,has,had都是實(shí)義動(dòng)詞。 “完

4、成時(shí)態(tài)結(jié)構(gòu)”如下：、 現(xiàn)在完成時(shí)：have / has + V-ed(過去分詞) eg. I/She have / has done my homework.、 過去完成時(shí)：had + V-ed(過去分詞)eg. She had left before/when I realized she was a cheat(騙子). eg. We had finished cleaning the classroom before the teacher came.、 現(xiàn)在完成進(jìn)行時(shí): have / has been V-ing(現(xiàn)在分詞) eg. I have been swimming in th

5、e cold water for about two hours.四、 無be，無情，也無助，則只有借助 疑問句專用助動(dòng)詞do,does或did，并將其提前后，且原實(shí)義動(dòng)詞形式務(wù)必要還原；五、 變?nèi)朔Q：原句中涉及第一人稱的人稱代詞、形容性物主代詞、名詞性物主代詞要變成第二人稱對(duì)應(yīng)的人稱代詞、形容性物主代詞、名詞性物主代詞；同樣，原句中涉及第二人稱的人稱代詞、形容性物主代詞、名詞性物主代詞要變成第一人稱對(duì)應(yīng)的人稱代詞、形容性物主代詞、名詞性物主代詞；eg. I like apples. Do you like apples ? 肯Yes, I do 否No, he doesnt.eg. This

6、 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動(dòng)也變化了) 肯Yes, you are 否No, you arent.六、 some或與some有關(guān)的不定代詞要變成any及any有關(guān)的不定代詞。someany, somethinganything, somebodyanybody, so

7、me oneany one, somewhereanywhere 不變的特殊情況如下：eg. I would like some drink.(變一般疑問句) Would you like some drink?原因是：表示發(fā)出誠懇的請(qǐng)求希望得到別人的肯定回答，或征求建議的一般疑問句，只能使用表示肯定的some 或 something 等不定代詞。七、附：句中含有 “used to + V原”結(jié)構(gòu)的變一般疑問句時(shí)，有兩種變法：1、借助助動(dòng)詞did 且提前，used 還原成use. eg.I used to watch TV after dinner. Did you use to watch

8、TV after dinner? 肯 Yes, I did. 否No, I didnt.2、也可直接將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)”等引導(dǎo)的賓語從句中，變疑問句時(shí)，無須考慮從句部分是否有be動(dòng)詞、情態(tài)動(dòng)詞或助動(dòng)詞，只需把主句部分變?yōu)橐蓡栒Z序就可。變成：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？難道你不認(rèn)為I didnt think/gue
