看不太懂
一般疑问句
1．将陈述句变为一般疑问句时,如句中有be 动词（am is are …）时,可直接将它们提至主语前.如主语为第一人称,应将其改为第二人称.如：
I'm in Class 2Grade 1． →
Are you in Class 2Grade
We're watching TV． →
Are you watching TV?
2．陈述句中有情态动词（can may must …）时,也可直接将它们提至主语前,即可成为一般疑问句.如：
He can swim now． →
Can he swim now?
The children may come with us． → May the children come with us?
3．陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does 主语后的实义动词用原形.如：
I like these animals． →
Do you like these animals?
She wants to go to the movies． → Does she want to go to the movies?
4．一般疑问句一般读升调(↑)
5．一般疑问句有时不用yes或 no 回答.如：
Are they in town now?
I think so.
May I sit here?
Certainly．
Does he like soccer?
Sorry I don't know．
6.一般疑问句的第一单词总是虚词,读的时候要读轻声.
二、特殊疑问句
以疑问词开头,对句中某一成分提问的句子叫特殊疑问句.常用的疑问词有：what（什么）,who（谁）,whose（谁的）,which（哪个）,when（何时）,where（哪里）,how（怎样）,why（为何）等.
特殊疑问句有两种语序：
1．如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序：疑问词（＋主语）＋谓语动词＋其他成分?如：
who is singing in the room?
whose bike is broken?
2．如疑问词作其他成分,即对其他成分提问,其语序是：疑问词＋一般疑问句语序?如：
what class are you in?
What does she look like?
Where are you from?
What time does he get up every morning?
How do you know?
注意：
1．回答特殊疑问句时,不能用yes ／ no,即问什么答什么,尤其是简略回答.括号内是完整回答所需部分.如：
Who is from Canada?
Helen (is from Canada)．
Where's the restaurant?
(It is)Near the station．
Why do you like koalas?
(I do like koalas)Because they are cute．
2．特殊疑问句一般读降调(↓).
