Question

小白一问！如何把一般过去时改为疑问句和否定句？

Answer 1

疑问句:1.
Were
you
at
home?
2.Was
she
at
school?
3.Were
you
in
a
traffic
jam?
注意系动词放在句首，人称转化。
否定句：1.
I
wasn't(was
not)
at
home.
2.She
wasn't(was
not)
at
school.
3.We
were
not
in
atraffic
jam.
在系动词后加not，注意was
和
not可以缩合。

Answer 2

改一般疑问句的话
把be动词提前
I
was
at
home。
一般疑问句
Were
you
at
home？
改特殊疑问句的话，疑问词加一般疑问句的语序，去掉提问的部分
如
She
was
at
school。
特殊疑问句
是
Where
was
she?
否定句是在be动词后面加not
如
We
were
in
a
traffic
jam。
否定句
为
We
were
not
(或weren't)
in
a
traffic
jam。
