wasn't
一般疑问句:Was it very hot yesterday?答语:Yes, it was./ No, it wasn't.
特殊疑问句How was the weather yesterday?=What was the weather like yesterday?
由以上例子可知，含有be动词was/were的
一般过去时的句子，变否定句时是在
was/were后面加not,可缩写为wasn’t/weren’t;变一般疑问句时是把was/were
提至主语前
其肯定回答为：Yes,主语+was/were;
否定回答为： No,主语+wasn’t/weren’t.

3)一般疑问句:Was/Were+主语+表语? Were they in the classroom?
