楼上都没做全对,正确答案如下：
I live (in the countryside) when i was a child.
Where did you live when you were a child?
They travel there (by train)
How do they travel there?
He (has a lot of stamps)
What does he have?
The woman (in a red skirt )is our English teacher
Which woman is your English teacher?
The bike (under the tree) is mine
Which bike is yours?
倒数第二句似乎括号不对,若照楼主所划的那样,就做成：
The woman (in a red skirt is our English teacher)
Who is the woman?
