Thereisafootballclub改为一般疑问句？
将“There is a football club.（有一个足球俱乐部。）”改为一般疑问句是：
Is there a football club?（有一个足球俱乐部吗？）
今天我们一起来学习，如何将肯定句变为一般疑问句。肯定句变为一般疑句有3种常见情况，下面我们对此逐一进行讲解。
1、肯定句中谓语部分带Be动词
be动词为系动词时，其句型结构为：主语+be+表语 这种系表结构的肯定句型中，变为一般疑问句只要将be动词调到句首即可。下面举例说明。
原肯定句：She is good at drawing .
一般疑问句：Is she good at drawing？
肯定和否定回答：Yes,she is/ No, she isn't.
这里的be动词为is 只要将is 调到句首，后面改为问号就行。是不是比较容易呢？
2、肯定句中谓语动词带情态动词
原肯定句中带情态动词，结构大致为：主语+情态动词+实意动词+宾语/其他。这种情况变为一般疑问句，同样将情态动词调到句首即可。比如下面句子。
肯定句：She can play the piano well.
一般疑问句：Can she play the piano well？
肯定和否定回答：Yes,she can,/No,she can't.
这里can 调句首大写字母c 后面加上问号就行了。也是比较容易的。
3、肯定句中只有实意动词
肯定句中既没有be动词也没有情态动词，实意动词单独做谓语的情况下，不能直接调实意动词到句首了！这个时候，我们用到助动词do或者does（视人称和数而定）助动词顾名思义，是用来帮助句式转换的。例如，
原肯定句：She speaks English well.
一般疑问句：Does she speak English well？
肯定和否定回答：Yes,she does/No,she doesn't.
这句子主语是第三人称单数，所以借助动词为does与之对应。但值得注意的是speaks要还原为speak，因为does是由do变为了第三人称形式的，所以后面的谓语动词speak不必再重复第三人称单数形式了。
但变一般疑问句的时候，主语为第一人称要改为第二人称，比如，I am late for school today. 变为一般疑问句为：Are you late for school ？原句的I为第一人称，变为了第二人称you。
还有特别值得一提的是，如果原句中包含了some的不定代词，变为疑问句和否定句往往都要改为any。再举个栗子给你们吧。
肯定句：She has some eggs for breakfast.
一般疑问句：Does she have any eggs for breakfast？
再如，
They have something to do .
改为一般疑问句为：
Do they have anything to do？
以上3种变一般疑问句的情况适用于其他时态和语态。例如过去时态肯定句：He stayed at home yesterday.
改为一般疑问句：Did he stay at home yesterday？
这个句子是过去时态，所以do 和does 也变为了相应的过去式did了。而变换的方法是相同的。
把“There is a football club.（有一个足球俱乐部。）”改为一般疑问句是：Is there a football club？（有一个足球俱乐部吗？）
关于英语句型转换(陈述句变一般疑问句)
1、什么是一般疑问句？
一般疑问句用于对某一情况提出疑问，通常用 YES 和 NO 来回答，读时可用声调加强语气。
2、变一般疑问句的方法：
A:把句子中的be动词提到句首（be动词包括：am is are）
例如：
I am a student.→Are you a student？
She is a teacher.→Is she a teacher?
They are good friends.→ Are they good friends?
B:把句子中的情态动词提到句首（情态动词包括can may must will should等）
例如：
She can play football.→ Can she play football?
I will help you. → Will you help me？
C:如果句子中没有be动词和情态动词，就要在句首加上助动词帮助其变成一般疑问句。（情态动词包括 do 和 does）
主语是第一、二人称和复数人称时在句首加上Do；
主语是第三人称单数形式时加Does。加上Does之后，原来句子中的三单形式要还原。
人称：第一人称：单数：I 复数：we
第二人称：单数：you 复数：you
第三人称：单数：she、he、it 以及人名 复数：they
例如：
You have a friend. → Do you have a friend?
She likes apples. → Does she like apples?
Amy does her homework at home.→ Does Amy do her homework at home?
注意：
1.句号变问号；
2.句子中的第一人称和第二人称互换；
I can help you . → Can you help me？
3.some→ any；
I have some apples. →Do you have any apples?
4.动词的三单形式还原问题。
She goes to school on foot. →Does she go to school on foot?
