☆注意☆ 小结：一般疑问句是在肯定句的基础上，
①把动词be调到首位，其他照写，末尾标点符号变成问号即可。
②没有动词be的句子则要在句首加上一个助动词（do，does，did）再把紧跟在后面的动词变回原形，末尾标点符号变成问号即可。
这三个助动词也要根据人称和时态来选择，其中“does”只用于一般现在时主语是第三人称单数的情况，而“did”只用于一般过去时，不论主语是什么人称和数，都用“did” 。一般疑问句有个重要的原则就是问和答要一致，即问句里的第一个单词（助动词）和简略答句里的这个词是一致的。
4、特殊疑问句：以特殊疑问词（what , where , who , which , when , whose , why , how等）开头引导的句子。此类句子应该问什么就答什么，不能用“yes 、no”来回答。如：
What is this? It’s a computer.
What does he do? He’s a doctor.
Where are you going? I’m going to Beijing.
Who played football with you yesterday afternoon? Mike.
Which season do you like best?
When do you usually get up? I usually get up at 6:30.
Whose skirt is this? It’s Amy’s.
Why do you like spring best? Because I can plant trees.
How are you? I’m fine. / I’m happy.
How did you go to Xinjiang?
☆其中how又可以和其他一些形容词连用组成特殊疑问词组用来提问，如： how many（多少(数量)）,
例句：How many pencils do you have? I have three pencils.
How many girls can you see? I can see four girls.
How many desks are there in your classroom? There are 51.
☆小结：how many 用来提问可数名词的数量，主要有以上三种句式搭配，
How many + 名词复数 + do you have?
How many + 名词复数 + can you see?
How many + 名词复数 + are there…?
完全、缩略形式
I’m=I am
you’re=you are
can’t=can not
isn’t=is not
won’t=will not
