英语的陈述句变疑问句,怎么变?

看句子里有没有be动词:如果有,将be动词提前到句首.
例: He is a clever boy.
Is he a clever boy?
没有be动词,看句子的主人是在哪个房间?如果在happy house,句首+Do.如果在sad house,句首+Does. 加过Does以后,后面的动词变成原型.
例: 1. They study English in the classroom.
Do they study English in the classroom?
2. He jumps rope in the park.
Does he jump rope in the park?

例:I am a teacher.
Are you a teacher?
We are happy?
Are you happy?
This is my book.
Is this your book?
These are our books.
Are these your books?
当句子里有some/many…要变成any.
例:There are some cats on the table.
Are there any cats on the table?
I have many shirts.
Do you have any shirts?

一、变为一般疑问句将陈述句变成一般疑问句,要根据陈述句中的谓语动词及其时态确定疑问形式.其句型特点一般是：助动词或情态动词 + 主语 + 谓语 + 动词 + 其他?
如：The policeman told the boys not to play football in the street.(甘肃省中考题) ______ the policeman ______ the boys not to play football in the street?答案：Did,tell
二、变为特殊疑问句将陈述句变成特殊疑问句时,常用的方法是“一选,二移,三变,四代”.
“一选”就是选择疑问词,被选择的疑问代词有：what,which,who,whose；疑问副词有：where,when,why,how；疑问副词词组有：how long,how often,how soon,how far,how many,how much,how old等.
“二移”就是把be动词,助动词或情态动词移到句首.
“三变”就是将原句中第一个单词的首字母改为小写(专有名词除外),将some,something等改为any,anything等,将句号改为问号.
四代就是将选好的特殊疑问词替代划线部分.
如：(西宁市中考题) At the age of three,David weighed 20 kilos.(就划线部分提问) ________ did David weigh at the age of three?答案：How much
三、变为选择疑问句将陈述句变成一般疑问句,在问号前加上“or + 所给的被选择部分”.
如：(*中考题) Most young men like popular music.(用 rock music 改为选择疑问句) ______ most young men like popular music ______ rock music?答案：Do,or (from www.zkenglish.com)
四、变为反意疑问句陈述句变成反意疑问句时一定要遵循“前肯定,后否定；前否定,后肯定”的原则.
------------
陈述句后面加一个简短问句可将陈述句变成反意疑问句,用以对所陈述的事情取得肯定或否定的回应,或
是使表达更加礼貌.反意疑问句很少用在正式的书面英语中.
例如：1） He’s very friendly,isn’t he?他很友好,不是吗?
2） You haven’t seen it before,have you?你以前没有见过,对吗?
2) You form a question tag by using an auxiliary,a modal,or a form of the main verb “be”,followed by a pronoun,the pronoun refers to the subject of the statement.
简短问句由一个动词和一个代词构成,动词主要由助词动词,情态动词和系动词“be”构成,代词指代主语.
例如：1） David’s school is quite nice,isn’t it?大卫的学校还不错,不是吗?
3) You can use a negative statement and a positive question tag to ask people for things,or to ask for his information.
由否定陈述句加肯定简短问句构成的反意疑问句可用以提出请求,要求帮助或寻求信息.
例如：1） You wouldn’t sell it to me,would you?你不会卖给我,是吗?
2） You won’t tell anyone else this,will you?你不会告诉别人,对吗?
4) When you want to show your reaction to what someone has just said,for example by expressing interest,surprise,doubt,or anger,you use a positive statement with a positive question tag.
由肯定陈述句加肯定疑问短句构成的反意疑问句可用以表达对某人所述事情的回应,例如表达兴趣,怀疑或 者愤怒.
例如：1） You’ve been to North America before,have you?你以前去过北美,是吧?
5) When you use an imperative,you can be more polite by adding one of the following question tags.
祈使句后面跟简短问句构成的反意疑问句更加礼貌.
(will you won’t you would you)
例如：1） Look at that,would you?看看那个,可以吗?
6) “Will you” and “won’t you” can also be used to emphasize anger or impatience.“Can’t you” is also used in this way.
“will you”,“won’t you” “can’t you”也可用以表示愤怒或不耐烦.
例如：1） Oh,hurry up,will you?你快点,行吗?
2) For goodness sake be quiet,can’t you?你能不能安静点?
