1、陈述句变成一般疑问句精编版陈述句变成一般疑问句:陈述句变为一般疑问句,首先看句中有没有系动词be或情态动词,如果有,把be或情态动词直接提到句首就可以了;如果没有,要用助动词do 或does 来帮助。基本句式如下:Be + 主语 +宾语 + 其他 + ?情态动词 + 主语 + 谓语 + 宾语 + 其他 + ?Do(Does) + 主语 + 谓语 + 宾语 + 其他 + ?(1)如果句子中有be动词(也就是说有is,am,are,were,was等)或是情态动词的(如can, could,will,would等),把be动词或情态动词直接提前,剩下的照抄,然后末尾加上问号。如:He is a s
2、tudent.(他是一个学生。)一般疑问句就是:Is he a student?.(他是一个学生吗?)They can play football.(他们会踢足球。)变成Can they play football?(他们会踢足球吗?)注意:如果主语是I或是we的,一般疑问句一般情况下要把人称改为you。反之you要改成I,we,me或us。如:I am a student. 一般疑问句就变成Are you a student?We can help you.(我们能帮你。)变成 Can you help me?(你们能帮我吗?)(2)如果没有be动词和情态动词的,就要用助动词来提问,助动词有
3、do,does,did。而选择哪个助动词就要由陈述句中的动词时态或形式来决定了。如:She speaks English very well.(她英语说得很好。)一般疑问句变成 Does she speak English very well?(她英语说得很好吗?)We finished our homework yesterday.(我们昨天完成作业的。)变为Did you finish your homework yesterday?(你们昨天完成作业的吗?)I go to school on foot.(我走路去上学。)变为Do you go to school on foot?(你走路
4、去上学吗?)选择好助动词后就可以把原句跟上去,要注意的是后面的动词要用原形了。如例子中的speak,finish等。另外,完成时态和have、has got(have got 是“有”的意思) 中的have或has也是提前,即与第一种be动词情态动词的用法相同。如:I have got a sister.(我有一个妹妹)改为:Have you got a sister?(你有一个妹妹吗?)完成时的例子:I have ever been to Beijing.(我曾经去过北京)Have you ever been to Beijing?(你曾经去过北京吗?)英语怎样做否定句,一般疑问句,对划线部
5、分提问 一、否定句1.主语+be动词+表语结构变否定句,直接在be动词后面加个not就可以了。Mr. White is a very good teacher.-Mr. White is not a very good teacher.2.主语+动词+其他当此句为一般现在时,在动词之前加dont或doesnt(第三人称单数形式),并将动词变为原形就可以了He loves playing football with his friends.-He doesnt love playing football with his friends.当此句为过去时,在动词之前加didnt,并且把动词变为原形
6、Toms sister graduated from high school last year.-Toms sister didnt graduate from high school last year.3.主语+情态动词+动词+其他在情态动词后面加not就可以了I can drive a car.-I cannot drive a car.4.主语+have/has+动词过去分词+其他在have/has后面加not就可以了The students have done their homework.-The students have not done their homework.二、一
7、般疑问句1.主语+be动词+表语结构变一般疑问句,把be动词提前,句子就变成 be动词+主语+表语结构?Mr. White is a very good teacher.-Is Mr. White a very good teacher?2.主语+动词+其他当句子为一般现在时,在句首加do或does,并且把动词变为原形,句子变成 Do/Does+主语+动词原形+其他?He loves playing football with his friends.-Does he love playing football with his friends?句子为一般过去时,在句首加did,句子变成 Di
8、d+主语+动词+其他?Toms sister graduated from high school last year.-Did Toms sister graduate from high school last year?3.主语+情态动词+动词+其他将情态动词提前,句子变成 情态动词+主语+动词原形+其他?I can drive a car.-Can you drive a car?4.主语+have/has+动词过去分词+其他将have/has提前,句子变成have/has+主语+动词过去分词+其他The students have done their homework.-Have
9、the students done their homework?三、对划线部分提问先找出划线部分在句子中所占得成分,找到对应的疑问词,将疑问词写在句首,再将原句变成一般疑问句,却掉划线的部分,写在疑问词后面就可以了。Tom bought a new computer from the store yesterday.若划线部分为Tom,Tom 是个人,且作主语,则疑问词应选Who, 此句应该为 Who bought a new computer from the store yesterday?若划线部分为a new computer, 划线部分为物,则疑问词为what,此句应为 What
10、did Tom buy from the store yesterday?若划线部分为from the store,则疑问词应为Where,表示地点,此句应为 Where did Tom buy a new computer yesterday?若划线部分为yesterday,则疑问词为When,表示时间,此句应为 When did Tom buy a new computer from the store?英语怎样变句型 一般疑问句 否定句 反问句 肯定句 画线提问0分 1. 由连系am,is,are构成的句子:变一般疑问句时把am,is,are提到句子的前面,句尾用问号即可。变否定句时直接
11、在am,is,are后面加not即可。例如: 肯定句:He is a student. 一般疑问句: Is he a student? 否定句: He is not a student. 反问句: He is a student, isnt he? He isnt a student, is he? 画线提问: 对he提问: Who is a student? 对 a student 提问: What is he? or What does he do? 2. 由情态动词can, may, should等构成的句子: 变一般疑问句时把can,may,提到句子的前面,句尾用问号即可.变否定句时直
12、接在can,may,后面加not即可. 例如: 肯定句: She can swim. 一般疑问句: Can she swim? 否定句: She can not swim. 反问句: She can swim, cant she? She can not swim, can she? 画线提问: 对she提问: Who can swim? 对swim提问: What can she do? 3. 由行为动词构成的句子: 需要加助词do或does. 变一般疑问句时把do/does放在句子前面. 例如: 肯定句: They play football after school. 一般疑问句: Do
13、 they play football after school? 否定句: They dont (do not) play football after school. 反问句: They play football after school, dont they? They dont play football after school, do they? 画线提问: 对they提问: Who play football after school? 对play football提问: What do they do after school? 对after school提问: When d
14、o they play football? 小学英语语法提高/一般疑问句和特殊疑问句疑问句可再分为一般疑问(General question)和特殊疑问(Special question)两种。 1.一般疑问:用be或助动词或情态动词置于句首,并以“Yes,”,或“No,”或相当于yes / no回答的问句称为一般疑问句. 2. 含系动词be的一般疑问句的构成具体地说,am 只能跟在第一人称的单数 I 后面,are 搭配 you, 不管是单数还是复数,is 跟在第三人称单数 he, she 后面,be 动词的基本意思:是如:Im in Class 2, Grade 1. Are you in
15、Class 2, Grade 1? 你是在一年级二班吗?(如遇第一人称,最好将其置换成第二人称)Its a map of China. Is it a map of China? 这是一幅中国地图吗? be 或 have(有)置于句首来表达疑问,例:Am I wrong again? (我又错了?) Yes, you are (wrong again). (是的,你又错了。) No, you arent. (不,你没错。) Is it your bicycle? (这辆自行车是你的吗?) Yes, it is. (是的,是我的。) No, it isnt. (不,那不是我的。) Were th
16、ere many people at her birthday party? (她的生日宴会来了很多人吗?) Yes, there were. (是的,来了很多人。) No, there werent. (没有,没有很多人。) Have you money with you? (你身上带钱了吗?)(=Do you have money with you?美语) Yes, I have.(Yes, I do.美语)(有,我带钱了。) No, I have no money with me. (No, I dont.美语)(没有,我没带钱。) 3. 含情态动词的一般疑问句的构成一般疑问句面前人人平
17、等:情态动词与am / is / are一样,也可直接将它们提至主语前,所以问题迎刃而解了。如: I can spell it. Can you spell it? 你会拼写它吗? Shall I call a taxi for you ? (需要我替你叫一辆出租车吗?) Yes, please. Thank you. (好的,谢谢你。) No, thank you.(不必了,谢谢你。) Will you do that for her? (你愿意替她做那件事吗?) Yes, I will.(是的,我愿意。) No, I wont.(不,我不愿意。) Can she drive? (她会开车吗
18、?) Yes, she can.(是的,她会。) No, she cant.(不,她不会。)4. 含实义动词的一般疑问句的构成含实义动词的一般疑问句的构成稍微有点讲究,要在句首加do;如逢主语为第三人称单数,谓语动词为一般现在时单数第三人称形式 v-(e)s时,用does,并要将谓语动词变回原形(如hashave,likeslike等);有时陈述句中的some还要变作any等。如:She lives in Beijing. Does she live in Beijing? 她住在北京吗?I like English. Do you like English? 你喜欢英语吗?There are
19、 some books on my desk.Are there any books on your desk? Do you speak Japanese? (你会说日语吗?) Yes, I do.(是的,我会说。) No, I dont.(不,我不会说。) Does she swim very well?(她游泳游得好吗?) Yes, she does. She is a good swimmer. (是的,她游得好。她是游泳高手。) No, she doesnt. She doesnt swim at all. (不,她不会。她根本不会游泳。) Did you tell her the
20、truth? (你向她说了实话吗?) Yes, I did.(是的,我说了。) No, I didnt.(不,我没说。) Dont you like to have a cup of coffee? (你不喜欢喝一杯咖啡吗?) Yes, I do.(要,我要一杯。) No, I dont. Thank you. (不,我不要。谢谢你。) 依循否定疑问要表达否定答案时,中文的习惯是“是的,不(或没有)”,但是英语应为“No, not.”,不可如中文说成“Yes,not.”。 5. 少数口语化的一般疑问句如问一个与前文相同的问句时,可省略成And you?或What / How about.?等;
21、甚至只抓关键词,读作升调。如:Your pen? 你的钢笔?6. 小插曲:一般疑问句的语调大部分的一般疑问句都应读作升调(),并落在最后一个单词身上。如: Is it a Chinese car? Do you have questions? Have you ever been to China before? Dont you think it is a good idea?7. 一般疑问句的应答用yes / no(或相当于yes / no的词)回答,并怎么问怎么答(句首为情态动词/am / is / are还是do /does),简略回答时要注意缩写(否定的nt)和采用相应的人称代词以避
22、免重复:即Yes,主语(代词)+情态动词或am / is / are或do / does.表示肯定;No,主语(代词)+情态动词或am / is / are或者do / does not(nt).表示否定。回答要完整,如: -Is Mary a Japanese girl? 玛丽是日本女孩吗?-Yes, she is. / No, she isnt. 是的,她是。/不,她不是。 -Can Lily speak Chinese? 莉莉会说中国话吗?-No, she cant. / Sorry, I dont know. 不,她不会。/对不起,我不知道。 -Do you like English?
23、 你喜欢英语吗?-Yes, very much. 是的,非常喜欢。小学英语语法时态讲解与归纳现在进行时现在进行时一意义当表示现在正在进行的动作或正在发生的事。 二构成:be (am, is ,are )+动词现在分词-ing形式肯定句: 主语 +be + 现在分词V-ing (+ 其他)Im doing my homework now .否定句:主语+be+not+动词-ing +其他.Im not doing my homework now.一般疑问句:Be+主语+动词-ing +其他?Are you doing your home work now?
