Question

【题目】I was playing with my phone when my mother came in. (改为否定句)

I________ ________ with my phone when my mother came in.

Answer 1

【答案】wasn't playing

【解析】

句意：我妈妈进来的时候我正在玩手机。我妈妈进来的时候我没有玩手机。

要求改为否定句。根据was playing可知句子时态为过去进行时，句中含有系动词was，其否定形式直接在系动词was后加not，缩写为wasn't，其它成分不变，故答案为（1）wasn't（2）playing。
