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”解題步驟找be動詞(am is are , was were )有則直接提前;egl. He is / was a teacher. => Is / Was he a teacher? 肯 Yes, he is/was 否 No, he is n' t / wasn' t.二、無be動詞，則再找情動(can may should must need)有情動則直接將其提前；eg2.I can play soccer. => Canyou play soccer? 肯 Yes, I can 否 No, I can ' t.( 注:can &

2、#39; t 容易多寫 n)注：need有可能不是情態(tài)動詞，怎么判斷？ =>根據(jù) "情態(tài)動詞+v原”的共性。因為：need、情態(tài)動詞：“需要”，后接：V原 、實義動詞：“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 needn ' t.eg4. You need to see a doctor. => Do I need to see a doctor?肯 Yes, you don' t. 否 No,

3、 you don' t.(eg3中的need根據(jù)“情態(tài)動詞+V原”的共性可以判斷是情動，但通常也不提前，要根據(jù)語氣選擇must開頭,同樣must開頭的一般疑問句的否定回答，一般要選擇用 needn' t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動詞，無情動，則再找是否有助動詞will,shall,would,have,has,had,有則直接將其提前；注：have.,has.,.had有可

4、能不是助動詞，怎么判斷？=>根據(jù) “完成時態(tài)”的結構。因為只有“完成時態(tài)”中才會有助動詞_hav.e,has_,had的存在，其他時態(tài)或位置的 h,ave,.has,ha.d,都是實義動詞。“完成時態(tài)結構”如下： 、現(xiàn)在完成時：have / has + V-ed(過去分詞)eg. I/She have / has done my homework. 、 過去完成時：had + V-ed（過去分詞）騙子）.eg. She had left before/whe n I realized she was a cheat（eg. We had finished cleaning the cla

5、ssroom before the teacher came. 、現(xiàn)在完成進行時：have / has been V-ing（現(xiàn)在分詞）eg. Ihave been swimming in the 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詞 do,does或did，并將其提前后，且原實義動詞形式務必要還原;形容性物主代詞、名詞性物主代詞;五、變人稱：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應的人稱代詞、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應的

6、人稱代詞、形容性物主代詞、名詞性物主代詞;3#eg. I like apples.=> Do you like apples肯 Yes, I do 否 No, he doesn ' t.eg. This is mybook.=> Is this your book?肯 Yes, it is 否 No, it isn ' t.eg. That computer ismi ne. => Is that computeryours肯 Yes, it is否 No, it isn ' t.#eg. Youare myfriends.=> Am I you

7、r friends? （Be 動也變化了）肯 Yes, you are 否 No, you aren ' t.六、some或與some有關的不定代詞要變成any及any有關的不定代詞。some=> any, someth ing => anything, somebody => an ybody, some one => any one, somewhere => any where不變的特殊情況如下： eg. I would likesomedrink.（ 變一般疑問句）=> Would you likesomedrink?some或someth

8、ing 等不定代詞。原因是：表示發(fā)出誠懇的請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4七、附：句中含有 “used to + V 原”結構的變一般疑問句時，有兩種變法：1、借助助動詞did 且提前， used 還原成 use. eg.I used towatch TV after dinner.=> Did youuse to watch TV after dinner?肯 Yes, Idid .否 No, I did n't.2、也可直接將used 提前 .eg.I used to watch TV after dinner.=> Used y

9、ou to watch TV after dinner?肯 Yes, I used.否 No, I usedn't.八、在含有 “ I think, I guessguessed ) , I believe(believed)”等引導的賓語從句中，變疑問句時，無須考慮從句部分是否有be 動詞、情態(tài)動詞5#或助動詞，只需把主句部分變?yōu)橐蓡栒Z序就可。變成：#I think/guess/believef Do you thin k/guess/ believe,？I thought/guessed/believedf Did you thin k/guess/believe,？#, ？難道你不認為,Idon'tthink/guess/believef Don' t you think/guess/believe#, ？難道你不認為,I didn 't think/guess
