小学英语问句总复习
★必备知识点:
1. be动词:am、is、 are、 was、 were形式。
2. 助动词:do、does、did、 have、 had 3. 情态动词can、must、will、may、need
一、肯定句、否定句定义
1.肯定句:表示肯定的意思, 即不含有否定词“不”。
例:我是一个学生 I am a student. 他去上学 He goes to school. 2.否定句:表示否定的意思。
例:我不是一个男孩。 I am not a boy 他不去上学 He does not go to school.
二、一般疑问句
(一)、什么是一般疑问句
用Yes或No作答的疑问句叫一般疑问句。一般疑问句还有下列特点: 1、以be动词、助动词或情态动词开头;
例:Is your father a teacher? Does Catherine like animals?
Can Jenny speak French?
2、往往读升调;
3、译成汉语,都可以带上“吗”,例如上面三句可分别译为:你父亲是老师吗?凯瑟琳喜欢动
物吗?詹妮会说法语吗?
★(二)、如何将陈述句变成一般疑问句?
要将陈述句变成一般疑问句,可以遵循下列步骤: 1.看句中有没有be动词(am、is、 are、 was、 were)、助动词(do、does、did、 have、 had)或情态动词(can、must、will、may等),如果有,将其提到句首,句末打上问号即可。 例:It was rainy yesterday. →Was it rainy yesterday?
Tom's father can play the piano. →Can Tom's father play the piano? I have finished my homework.→Have you finished your homework?
2.如果句中没有be动词、助动词或情态动词,则根据谓语动词的形式借助do的相应形式放
在句首。具体方法是:如果谓语动词是原形,则借do;如果谓语动词是一般现在时第三人称单数形式,则借does;如果谓语动词是过去式,则借did.需要注意的是,借does或
例:They go to school by bike. →Do they go to school by bike?
Bill gets up at 6:30 every day.→Does bill get up at 6:30 every day?
The students saw a film yesterday. →Did the students see a film yesterday?
★(三).陈述句变一般疑问句应注意的事项
陈述句变成一般疑问句除了遵循上述规则以外,还应注意下列几点: 1.如果陈述句中有第一人称,则变问句时最好要变为第二人称。 例:I usually have lunch at school.
→Do you usually have lunch at school? My father is playing soccer. →Is your father playing soccer?
2.如果陈述句中有some, 则变问句时往往要变成any 。 例: There is some water on the playground. →Is there any water on the playground? 3.复合句变一般疑问句通常只变主句,从句不变。 例:I know he comes from Canada.
→Do you know he comes from Canada?
4 .如果句中含有实义动词
have且表示“有”时,除借do外,也可将其直接提到句首。
例:I have some friends in America.
→Have you any friends in America?/Do you have any friends in America?
(四).一般疑问句的回答
一般疑问句往往采用简短回答,共由三部分(三个单词)组成,对这三部分(三个单词)的确定可以概括例下:
1.第一个词:不是Yes就是No。(注意:有时根据语气的不同,Yes可由Sure, Certainly,
Of course等代替.No可由sorry 代替.)
2.第二个词:问谁答谁。即答语中的主语须与问句的主语一致。 例:Does she clean her room every day? Yes, she does. Is Anna′s father a doctor? No,he isn′t.
如果主语是 this that,回答时用 it 代替,如果问句中主语是these, those
回答时用 they代替。
3.第三个词:用什么问,用什么答。即沿用问句中的引导词。 例:Can Jim play soccer? Yes, he can.
Does Mr Bean speak English? Yes, he does. 需要注意问题:
用 may 引导的问句,肯定回答用may,否定回答用 can′t 或mustn′t, 用 must 引导的问句,肯定回答用 must,否定回答用needn′t. 例:May I go to the park now? Yes, you may. /No, you mustn′t.
Must I wash my clothes now? Yes, you must. /No, you needn′t.
4.用No开头作否定回答时,结尾要加上 not。因为回答必须是三部分,所以否
定回答必须缩写,而肯定回答不能缩写。
例:Did Thomas come here yesterday? Yes, he did./ No ,he didn′t.
