疑问代词:
在句子中用来构成特殊疑问句,主要用于询问“何人”、“何事”、“什么”。
常见的疑问代词如下表所示:

疑问代词

替代范围

who

whom

whose

which

人、事、物

what

事、物


对事物作出肯定判断的句子叫肯定句。
对事物作出否定判断的句子叫否定句。
结构:主语+谓语+其他 
例:Tom played football yesterday afternoon. 汤姆昨天下午打篮球了。 
         This is my bedroom. 这是我的卧室。
肯定句分类:
A、使用“是”字句,也叫判断句。 
B、使用一般的肯定句式。

肯定句、否定句、一般疑问句和特殊疑问句的相互转换:
1、有am, is, are的句子,
就划线部分提问(变特殊疑问句)
This is a book.
第一步:变一般疑问句 Is this a book?
第二步:找合适的特殊疑问词 Is this what ?
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。What is this?

2、没有am, is, are的句子,
肯定句变否定句:在主语后面加上do not或者does not,其余按顺序照抄动词用原形
肯定句变一般疑问句:在句首加do或者does并大写,其余照抄。注意:动词用原形
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: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"。     

3、划线部分不能在特殊疑问句中出现。
非单三时用do,单三时用does
非单三:
肯定句:I like English.
 一般疑问句:Do you like English?
否定句:I do not like English.
单三 :
肯定句:He likes English.
一般疑问句:Does he like English?
否定句:He does not like English.
就划线部分提问:
I like English.
第一步:先变一般疑问句 Do you like English?
第二步:找合适的特殊疑问词代替划线部分Do you like what?
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。What do you like?

4、特殊:
①some变为any。如:
There are some birds in the tree.→There aren't any birds in the tree.
但是,若在表示请邀请、请求的句子中,some可以不变。如:
Would you like some orange juice?
与此相关的一些不定代词如something, somebody等也要进行相应变化。
②and变为or。如:
I have a knife and a ruler.→I don't have a knife or a ruler.
③a lot of (=lots of)变为many或much。如:
They have a lot of friends.(可数名词)→They don't have many friends.
There is lots of orange in the bottle.(不可数名词)
→There isn't much orange in the bottle.
④already变为yet。如:
I have been there already.→I haven't been there yet.


肯定句的组织结构:
主系表:eg:I'm a girl.
主谓宾:She write a leter to him.
1.主语+系动词(be)+表语                      
2.主语+call +宾语+宾语补足语                      
3.主语+name +宾语+宾语补足语
4.主语+is called +宾语补足语
5.主语+is named +宾语
6.主语+regard +宾语+as +宾语被足语
7.主语+be +no (none)+other than (but)+表语

否定句:
表示否定的句子。必须有否定词。
否定句的构成形式:
a. 谓语为be动词时,“be+not "一名学生。
b. 谓语为实义动词而且没有情态动词和助动词时,“do/ does/ did+not"构成否定。 
例:I do not like dancing. 我不喜欢跳舞。 
      He does not want to go to school. 他不想去上学。
c. 谓语为“情态动词+实义动词”时,“情态动词+not”构成否定。 
例:You must not smoke. 你千万不要吸烟。 
       I can not catch it. 我抓不住它。
否定句在英语语法中可以分为九类:

He doesn't know English, let alone/to say nothing of/not to speak of(更不用说)French.
(6)半否定句

(9)加强否定

否定转移的形式与用法:
一、动词的否定转移
1.形式上否定主句的谓语,实际上是否定从句的谓语
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”的主语是第一人称,谓语动词为没有任何副词修饰的一般现在时,它们的否定式实际上是对宾语从句的否定。
表示说话者提出一种委婉的看法或主张。如:
I think that he will help us.——I don’t think that he will help us. 我认为它不会帮助我们。
I believe that he is right.——I don’t believe that he is right. 我认为他不对。
I suppose that he likes it.——I don’t suppose that he likes it. 我想他不喜欢它。

2. 形式上否定谓语动词,实际上否定复合宾语
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”、“find”的主语是第一人称,谓语动词为没有任何副词修饰的一般现在时,它们前面的否定式实际上是对复合宾语的否定。表示说话者所提出的一种委婉的看法或主张。如:
I think math difficult. — I don’t think math difficult. 我认为数学不难。
I find the story interesting. — I don’t find the story interesting. 我认为这个故事没有趣。
I expect so. —I don’t expect so. 我认为不会。

二、动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”在下列情况下,否定不转移:
1.这些动词跟其他另一个动词一起做并列谓语时,否定不转移。如:
I believe and hope he won’t do that. 我相信并且也希望他将不会那样做。
I feel and admit that we are not foolish. 我觉得并且也承认我们并不愚蠢。

2.用于疑问句时,否定不转移。如:
Do you think it is not going to rain? 你认为天不会下雨吗?
Don’t you believe that he has done a good thing? 难道你不相信他做了一件好事?

3.用作插入语时,否定不转移。如:
Li Lei, I think, won’t be angry with you. 我想李蕾不会生你的气。
Tom, I suppose, won’t be against it. 我猜想汤姆不会反对。
Mike, I believe, hasn’t seen the film. 我认为迈克没有看这场电影。

4.动词前有其他副词修饰时,否定不转移。如:
I really don’t think it’s necessary for us to go there now. 我的确不认为我们有必要去那儿。
I feel strongly that he shouldn’t do such a thing. 我强烈地认为他不应该做那样的事。

5.动词为非一般现在时或主语不是第一人称时,否定不转移。
I thought that he wouldn’t come back soon. 我原以为他不会回来得这么快。
She didn’t believe that he became a good boy. 她不相信它变成了一个好孩子。
He thinks that he isn’t fit for the job. 他认为他不适合这件工作。
He doesn’t believe that what we told him is true. 他不相信我们告诉他的事是真的。

6.当宾语从句中含的否定为“not……at all”、“not a little”、“not a few”、“not enough”、“can’t help”等固定搭配时,否定不转移。如:
I think that he doesn’t know it at all. 我想他对那一点也不知道。
I suppose that it is not enough to remember the words if you want to learn the language well. 我认为如果你想把这门语言学好,那么只记单词是不够的。
I believe that you can’t help singing our national anthem when you win the first place in the Olympic Games. 我相信当你在奥运会上获得第一名时你会情不自禁地唱起国歌来。

7.当宾语从句中含“no”、“nothing”、“nobody”、“nowhere”、“hardly”、“seldom”、“little”、“few”等否定词或半否词时,否定不转移。如:
I believe that nothing can make me give it up. 我想任何事情也不能使我放弃。
I think that no one can escape if the ship sinks in the sea. 我认为如果这艘船沉入海底的话,那么谁也逃不掉。
I suppose that he is a man of few words. 我猜想他是一个言语不多的人。


一般疑问句:
是疑问句的一种。它是以be动词,have或助动词、情态动词开头,用yes(是)或no(否)来回答的句子。
其结构是:系动词be/助动词/情态动词+主语+其他成分
一般疑问句的肯定形式为:
助动词+主语(+实义动词)。肯定答语用“yes+可定结构”。 
一般疑问句的否定形式为:
助动词构成的缩写否定词+主语(+实义动词)。否定答语用“no+否定结构”。
例:
— Do you like this story-book? 你喜欢这本故事书吗? 
— Yes, I do. 喜欢。/ No, I don’t. 不喜欢。 
— Is he a student? 他是一名学生吗?
— Yes, he is. 是,他是。/ No, he isn’t. 不,他不是。

一般疑问句的改写:
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?

四、一般动词的一般疑问句,也要借助助动词do/does,第三人称单数用does,其余人称用do。
其句型为:Do/Does + 主语 + 动词原形+其它?
陈述句:Amy speaks English.
一般疑问句:Does Amy speak English?

一般疑问句的回答:
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.
