英语过去进行时变一般疑问句，特殊疑问句如和变化

1英语过去进行时变一般疑问句。
例如 I was watching tv at at that time of yesterday
改为一般疑问句---Was you watching tv at that time of yesterday？

2.特殊疑问句如和变化
特殊疑问句-以特殊疑问词开头，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 、who 、whose 、which 、when 、where 、how 、why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：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：特殊疑问词+一般疑问句【特殊疑问词+be/助动词/情态动词+主语+谓语/表语
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﹖
且回答特殊疑问句时，不能用yes / no，即问什么答什么，尤其是简略回答。如：
Who is from Canada﹖
Helen (is)．
Where's the restaurant﹖
Near the station．
Why do you like koalas﹖
Because they are cute．

与现在进行时相同
e.g. I was reading at this time yesterday.
Were you reading at this time yesterday?
对reading划线提问
What were you doing at this time yesterday?
