I am going to have a long holiday.（改为一般疑问句）
Tim went to Australia yesterday.（改为一般疑问句）
Kate and Bob were in Beijing (for two weeks).对括号部分提问

Answer 1

一般疑问句
Are you going to have a long holiday?

含系动词be的一般疑问句的构成
具体地说，就是当陈述句中有am /is / are时，可直接将它们提至主语前，但如遇第一人称，最好将其置换成第二人称。
如：
I’m in Class 2, Grade 1. →Are you in Class 2, Grade 1?

一般疑问句
Does Tim go to Australia yesterday

含实义动词的一般疑问句的构成稍微有点讲究，要在句首加do；如逢主语为第三人称单数，谓语动词为一般现在时单数第三人称形式"v-(e)s"时，奉does为座上宾并要变回原形(如has→have，likes→like等)；有时陈述句中的some还要变作any等。

对括号部分提问
How long were Kate and Bob in Beijing ?
