一、含有be动词的一般疑问句,通常把be动词调到句首。例如:
陈述句:They are in the swimming pool.
一般疑问句:Are they in the swimming pool?
注意:一般疑问句句末要用“?”。
二、含有情态动词的一般疑问句(can, may...),把情态动词调到句首。例如:
陈述句:He can drive a car.
一般疑问句: Can he drive a car?
三、含有have的一般疑问句,have译为“有”。一般疑问句式有两种形式:
1.把have/has调到句首。例如:
陈述句:Tommy has a computer.
一般疑问句:Has Tommy/he a computer?
2.加助动词do/does,第三人称单数用does,其他人称用do。其句型为:Do/Does + 主语 + have...?例如上句可变为:
Does Tommy have a computer?一般疑问句:以be动词, have /has/do等助动词、can/may等情态动词开头,以yes或no来回答的问句。
它的基本结构是:Be/Have /Has/Did等助动词(包括情态动词)+主语+谓语(包括表语)+┄?回答常用简略回答。
四、句子里没有be动词、助动词、情态动词(am/is/are/was/were/will/can/may/must/could/have/has[有])等,就需要加助动词do, does,(三单)、 did(过去式)来构成疑问句,加上这些助动词后,句子中谓语动词必须用原形。
其句型为:Do/Does/did + 主语 + 动词原形+其它?
陈述句:Amy speaks English.
一般疑问句:Does Amy speak English?
注意:在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody等词,如果有也必须进行改变,already要改成yet,some、something、somebody等分别改成any、anything、anybody等。另外,在改成否定句的时候注意把too改成either,both改成neither,all改成none等.在改成一般疑问句的时候,常常把第一人称I、we改成第二人称you。
好了,知道了如何问话之后,我们来了解一下如何回答一般疑问句。首先要有人称的改变。当主语为名词时,在答语中要改成其相应的代词。另外,答语有两种,肯定的回答(用yes)和否定的回答(用no),否定式常用缩写形式。现在还是让我们分句型一一说明。
一、一般疑问句含be动词时,用be动词回答,句末用句号。例如:
-Is Mary your sister?
-Yes, she is. / No, she isn’t.(缩写)
二、一般疑问句含有情态动词(can, may, should等)时,用情态动词回答。例如:
-May I come in?
-Yes, you may. / No, you can’t.
三、一般疑问句含有have(译为“有”)时,有两种回答方式。
1.直接用have/has回答。例如:
-Have they any pictures?
-Yes, they have. / No, they haven’t.
2.用助动词do/does回答。例如:
-Does Millie smoke?
-Yes, she does. / No, she doesn’t.
四、一般动词的一般疑问句回答时也用助动词。例如:
-Do the workers live in London?
-Yes, they do. / No, they don’t.
陈述句变一般疑问句的方法:
1)对于助动词、情态动词、be动词作谓语的,掉换主谓。如:
He's a teacher.
Is he a teacher?
He can swim.
Can he swim?
He'd like to go there.
Would he like to go there?
2)对于实意动词作谓语的,动词原型借助do,三人称单数借助does,过去式借助did,加在句首,再把谓语改为动词原型。如:
I like him.
Do I like him?
He likes me.
Does he like me?
I liked him.
Did I like him?
特殊疑问句:
先改一般疑问句,去掉要提问的成分,再在句首加相应疑问词。如:
I will go there by bus.
Will I go there by bus?
把一般陈述句里的am,is,are放在主语前,如果是谓语动词则把do,does,did放在主语前,谓语动词还是跟在主语后,如果谓语动词为过去时则把助动词did放在主语前,谓语动词改用一般现在时。然后把句号变成问号。如He is a student.变一般疑问句为:Is he a student?
He finished his homeworks.变一般疑问句为:Did he finish his homeworks?
把be动词(is, am, are)或者助动词(do)提前,其它词语序不变,句末加问号即可 = =
把be动词提前
