Question

There was a library at that time。改办一般疑问句？

Answer 1

1、把原句的be动词（is/are/am/was/were）提到句首，注意时态和原句保持一致；
Was there a library at that time?
那时候（这儿）有个图书馆吗？
2、如果句中有情态动词（must/may/can），改为一般疑问句则把情态动词提到句首，注意句子时态和原句保持一致；
3、如果句中无be动词或情态动词，也借助助动词do(does/did)加not的否定式，改为否定句。

Answer 2

一般疑问句:Was there a library at that time?
句意:当时有图书馆吗？
分析:把含有be动词的句子改为一般疑问句时，把be动词提前，句末加问号。

Answer 3

一般疑问句：Was there a library at that time?
否定句：There was not a library at that time.
was是助动词，直接左边移即可。

Answer 4

一般疑问句是:Was there a library at that time?把be动词提前就可以了。

Answer 5

一般疑问句Was there a library at
that time?
