一般疑问句

一般疑问句

在英语的学习中，一般疑问句的转换及回答是经常碰到的问题，现在我们就来探讨一下有关一般疑问句的问题。

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 she like animals? Can Jenny speak Chinese?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？她喜欢动物吗？Jenny会说英语吗？

二、例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）、和情态动词（can、must、will、may等），如果有，将其提到句首，句末打上问号即可。

例：She is a girl.

→Is she a girl?

Tom's father can play the piano.

→Can Tom's father play the piano?

练习：

1.This is a boy

2.It is a cat .

3.This is your sister.

4.Those are my books.

5.These are apples.

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或者主语是第一人称、第二人称、第三人称复数则借do；如果谓语动词是一般现在时第三人称单数形式，则借does；需要注意的是，借does后，原句的谓语动词要变回原形。

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?

练习：

1.I love my parents.

2.I play computer games every night.

3.I have a TV.

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．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?

综合练习：

1. His father is an English teacher.

2. These cats are crying.

3. They can swim.

4. I like to read English.

肯定句及祈使句变否定句

中考句型转换错误分析肯定句变否定句 1. I think she is there. 误：I think she isn’t there. 正：I don’t think she is there. 析：英语中think, believe, expect, suppose等表示信念和揣测的动词，后接that从句时，习惯上将从句中的否定形式转移到主句上，即否定主句谓语，不否定从句谓语。 2. He can sing this song and that one. 误：He cannot sing this song and that one. 正；He cannot sing this song or that one. 析：肯定句中的连词and在否定句中一般要改为or。 3. Tom went to school too. 误：Tom didn’t go to school too. 正：Tom didn’t go to school either. 析：too和also用于肯定句中时，否定句中用either替换。 4. He has had supper already. 误：He hasn’t had supper already. 正：He hasn’t had supper yet. 析：随着对谓语动词的否定，某些副词也要作相应的变动。 5. He had a good rest just now. 误：He hadn’t a good rest just now. 正：He didn’t have a good rest just now. 析：have在表示开会、吃饭、休息、进行体育锻炼等词组中是行为动词，否定句用助动词来完成。 6. Let’s do it.

肯定句、否定句、一般疑问句和特殊疑问句的讲解与练习一．句子的种类

一、be动词：am, is, are 二、肯定句、否定句、一般疑问句和特殊疑问句定义 1．肯定句：表示肯定的意思, 即不含有否定词“不”。 比如：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。 比如：我不是一个男孩。 I am not a boy. 他不去上学 He does not go to school. 3. 一般疑问句：回答为“是yes”或者“否no”的问句。 比如：你是一个学生吗？ Are you a student? 你喜欢英语吗？ Do you like English? 4. 特殊疑问句：回答不是“是yes”或者“否no”的问句，根据提问内容具体回答。 比如：现在几点了？What’s the tim e? 哪一支笔是你的？ Which is your pen? 三、肯定句、否定句、一般疑问句和特殊疑问句的相互转换 有am, is, are的句子，

肯定句变一般疑问句：把am, is, are提前放到句首并大写Am, Is, Are,其余照抄。 肯定句变特殊疑问句（就划线部分提问）：分3步骤 第一步：先变一般疑问句。 第二步：找合适的特殊疑问词代替划线部分。 第三步：特殊疑问词提前放到句首，并大写，其余按顺序照抄，省略划线部分。 注意：1.一定先变一般疑问句。但是，如果问的是主语或主语的定语时，语序不变， 为"特殊疑问词(+主语)+陈述句"。 如：Liming 's not here today. Who's not here today? 今天谁没来？ 2.划线部分不能在特殊疑问句中出现。
