“肯定句變一般疑問句”解題步驟

1、“肯定句變一般疑問句”解題步驟 “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(wú)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

2、情態(tài)動(dòng)詞，怎么判斷？根據(jù) “情態(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(yǔ)氣選擇m

3、ust開頭,同樣must開頭的一般疑問句的否定回答，一般要選擇用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、 無(wú)be動(dòng)詞，無(wú)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(guò)去分詞) eg. I / She have / has done my homework.、 過(guò)去完成時(shí)：had + V-ed(過(guò)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

I like apples. Do you like apples ? 肯Yes, I do 否No, he doesnt.eg. Th

6、is 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,

7、some 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(chéng)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 watc

8、h 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(yǔ)從句中，變疑問句時(shí)，無(wú)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(yǔ)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/guess/believeDidnt you thin
